The Reason For The Decline In US Manufacturing

In 2006, almost all of the US based companies that made the majority of the components used in the line of Pure Air Systems fan powered, HEPA based air filtration systems, closed up their R&D and Manufacturing centers and moved them overseas. Many went to China. They only left the sales and management operations in the US. There are a number reasons for this departure.

China and other countries in the far east started to compete with US manufactured goods and they were less expensive and just as good as those made here. Since most of the larger manufacturing companies are publicly held their shareholders were concerned that trying to compete head-to-head on price was not feasible and they did not want to lose any of their profit margins. Secondly, it is very, very, very expensive to build and operate a manufacturing operation. It requires a lot of equipment and experienced, well-trained technicians and engineers. Over the years those people entering the engineering field of study dropped off precipitously. So they decided to minimize their losses and have their products made overseas.

Over time the public came to accept products made in China, Vietnam, Cambodia, Indonesia, etc. and the advent of Amazon changed the way everyone purchased everything without caring about the manufacturing origin. This coupled with the fact that the new generation of workers are primarily involved in the digital world and have little or no interest in working with their hands and see no future in that arena. Their future belongs to AI, Additive Manufacturing, Robotics and VR and AR technologies.

Pure Air Systems has been manufacturing commercial grade, high performance HEPA based air filtration systems since 1985 and now one of only three companies in the world that currently manufacture this type of equipment.

Getting Ahead Using New Technology

The manufacturing world is awash with new concepts and techniques. The use of AI along with Additive Manufacturing and Robotics have enabled many start-ups and small product development companies to offer better products that meet or exceed the expectations of their current customer base.

The use of AI in every aspect of their company structure, from marketing to customer support and product enhancement have created a need, in many cases, for a different breed of employee. In many cases their current base of employees don’t have the expertise to use many of these new concepts. Also, the addition of  VR and AR technologies are providing for collaboration with experts outside their own company to speed up the development of new products and get them into the market faster. The world of technology is now moving at light speed.

Many companies that use CNC machines for making steel parts have additive 3D printers or Additive Manufacturing  do both prototyping and in many cases actual manufacturing in lieu of their CNC machines. This affords faster design changes and the ability to make products that can’t be made using CNC operations.

Pure Air Systems is a manufacturer of high end, commercial grade, fan powered HEPA air filtration systems for both the residential, commercial, industrial and institutional markets. They have been in business since 1985 and were one of the first companies in the US to incorporate ECM motors into all of their systems. They now offer systems with complete digital and computer controlled motors to handle every type of air filtration application.

Pure Air Systems. Staying the course after 37 years.

In today’s global, fast-paced, ever changing business world, companies that last longer than 10 years is unusual. Typically newly formed successful companies are either acquired shortly after they become public or they merge with some similar technology firm to expand their customer base quickly.

Pure Air Systems began its journey in 1985 with one HEPA filtration system that was large and difficult to use or install. HEPA systems were just beginning to be accepted in the residential and commercial markets and the cost of making the systems was steep due to the fact that the housings had to be all metal and the HEPA filters, motors and fans were all commercial grade components that required large quantity purchases to obtain any type of cost reduction. Even at that, the first unit, Model 600H cost over $600.00 in components and another $50.00 in assembly time.

Marketing the systems was somewhat difficult in that the use of computers to promote products was somewhat limited so mail and direct marketing in the form of door-to-door selling was incorporated. It wasn’t until a year later that Pure Air Systems set up it’s first and only URL. www.pureairsystems.com . The ability to use the internet to promote the systems allowed for quick introduction of a unique and highly sought after HEPA air filtration system.

By 1992 PAS had set up a series of distributors and added two more systems to its portfolio and began to outsource its production and assembly to a company in northern Indiana. By 1995 PAS had enough business to start looking for a place of its own to produce the systems and have enough space to store all the replacement filters necessary to feed the hundreds of units now in place across the U.S. In 1998 PAS broke ground on a new 9,000 sq.ft. building. In 1999 the move into the new building allowed for more R&D which produced 4 more HEPA unit designs along with a brand new HEPA portable that was one of the best on the market. 

By 2001 PAS was selling seven different models of its fan powered, HEPA based, ECM motor driven air filtration systems. The use of the new GE ECM motors allowed for use with 120/240 50/60Hz power. Thus allowing for the use in overseas markets which expanded the companies footprint out the U.S. for the first time. 

Today, Pure Air Systems is one of only three companies in the world that make this high performance, commercial grade HEPA air filtration system. The units now range in volume from 50 CFM to 2000 CFM and use programable ECM motors with high end digital controllers.

Training The New Manufacturing Generation

It is no secret that the men and women under 35 are much less likely to enter the field of “making things” including the millennials and generation Z population. Unlike the WWII generation that helped build the US into one of the best manufacturing countries in the world, the new generation is all about the digital world and working from anywhere using the latest in AI and Virtual Reality technology.

There are still some manufacturing done in the US, but the vast majority of small parts, motors, appliances, etc, are now made overseas. Those remaining manufacturing companies are finding that the public school systems, community colleges and four year universities are no longer providing any type of hands-on training in the use of tools or machining equipment.

Many companies have decided to put their own training programs in place and create new manufacturing specialists organically. It seems to be the only answer to keeping their companies up to speed and competitive in a market that is constantly changing and creating new technologies. With the new generation of men and women moving faster into the digital world it is obvious the manufacturing companies in the US are going to have a more difficult time in staying relevant in their fields without some major changes in the way manufacturing is done.

Pure Air Systems manufactures a line of HEPA and Carbon based air filtration systems and as a 37 year old company they are one of only three companies in the world making their type of systems. For more information on the complete line of their air filtration units please go to their website at:  http://www.pureairsystems.com   or call them on their toll-free number at: 800-869-8025.

Additive Manufacturing Moving To Replace Machining Processes

There are two main factors that are moving the process of using 3D Printing or Additive manufacturing into the product producing mainstream and replacing the traditional machining, CNC and injection molding processes. First, the number of skilled machinists and manufacturing engineers is rapidly declining and secondly, and most important, the younger generation has little or no interest in working for or with any manufacturing operation. The new generation sees their future in the digital world.

The other major reason is the speed in which additive manufacturing has advanced in every facet of product production. This is especially true in the use of additive manufacturing in producing parts from ferrous and nonferrous materials. The ability to produce a steel part that is one piece versus multiple parts or pieces using traditional machining is now blazing new trails in the ability to make a part in one print cycle that used to take five to eight steps. Also, the ability to quickly prototype a part and then change it and print again for five or more iterations in the span of one reduces prototyping and product development to less that 10% of the time for traditional machining.

Interestingly, the method of designing a part for manufacturing is identical in both traditional and additive manufacturing. The use of advanced CAD software allows for the design of any part and the design files are saved in different file types depending whether the part is made on a CNC machine or 3D Printer. This new generation of young workers already know how to use this software as their understanding computers, software, programming and object design is already in place. So, the 3D Printer is a perfect fit for this new group of workers who most likely will work remotely from the actual manufacturing operation.

Pure Air Systems began its operation in 1985 using hand drawings for the design of its HEPA based air filtration systems and then eventually moved into the CAD era and today is looking at using AI for some of its advanced equipment designs. The world of technology is moving at light speed and Pure Air Systems is keeping pace.

Artificial Intelligence Now Ubiquitous

In less than one year, the adaption of AI is not used in almost every facet of our lives. There is no industry or service business that is not using one or more of the AI programs that are being added to and updated daily. In fact, if your business is not incorporating AI into its operational profile it will fall behind its competitors very quickly.

For many people the use of AI has created visions of a massive take-over of our lives by some super intelligent machines. ( In truth that has already started). This belief is held mostly by older Americans who have a minimal understanding of technology and the vast knowledge base held in the Cloud. Change is always difficult for some people but the younger generation adapts quickly and they are using AI almost daily.

But AI is also being used in the engineering, design and product development arenas and this is where the real advantages are taking place. The use of engineering AI programs has tripled in the last year and the benefits have been amazing. Companies now know that they can use AI programs to accelerate their prototyping and product to market development process.

Pure Air Systems opened its doors in 1985. The use of any type of digital technology was limited to crude computer systems and reams of paper tape. All of the information gathered came from human sources and books. Designing a new filtration system took months and a fair amount of trial and error. All in all, it took 8 months to a year to develop a new product or modification to an existing system.

Today, adding a new product or modification can take as little as 1 to 3 months to complete, and the information is derived from the digital world. This adaption of digital information and/or AI is a necessary part of using technology to make us more productive and better our lives. It is important to realize that everything changes and change is constant.

Filtered Air Makes for Better Manufacturing

Manufacturing in many cases requires large pieces of equipment that may generate large amounts of particulate during their operation. This is especially true for milling, grinding and cutting machinery. While many of these systems may have some general duty dust collection equipment, fine, airborne particulate may float in the air and land on the various parts and other equipment located in the manufacturing operation.

Fine metal, plastic or wood particles that are sub-micron in size ( not visible to the naked eye ) can get inside areas of a part like threads, gasketed connections, glass layers or liquid containers prior to being filled. Over time these particles will affect the quality and potential performance of the part or parts that are being manufactured.

Pure Air Systems, a manufacturer of commercial grade HEPA based air filtration systems, has been installing their fan powered multi-stage equipment in commercial and institutional facilities since 1985. These fan powered units can be used in either as stand-alone units or configured to attach to existing HVAC units. 

The PAS systems can move up to 2,000 CFM and can be ducted to a hood that is located either over the manufacturing process or using close capture hooding for best reduction/removal of the small sub-micron airborne particulate. Over the past 37 years PAS has installed many of these systems in similar applications with the end result being a greater production rate with fewer rejects and part returns.

Airborne Viruses And Your Health

It has been repeated many times online and in articles in every type of publication that we tend to not become fearful of things we can not see. And yet, the biggest challenge we have as humans is the transmission of airborne viruses that affect everyone multiple times in their lives. From the yearly Flu bug to Covid 19 and the Common Cold, all of these airborne viruses are constantly searching for a warm host to stay alive and grow.

For many of the airborne viruses there are anti-viral shots available to either eliminate your chances of getting it or minimizing the symptoms if you do get sick. For some reason, there are a number of groups ( all non-medical ) that constantly provide warnings about the various bad side affects of getting injections for all types of viruses. This has created a huge problem for the medical industry as more people are getting sick and in many cases requires them to be hospitalized. In many cases these anti-immunization groups even target mumps, measles and now polio. 

Yes, viruses are extremely small and not visible with the naked eye, but they can be and are significantly reduced or eliminated using filters such as HEPA and SULPA filters. These filters capture airborne viruses and are used in medical facilities around the world. Some of these HEPA systems are available to homeowners and small businesses here in the U.S. Since Covid, the increase use of these type of systems in commercial and institutional environments has doubled. However, with the public continuing to deny the value of anti-virual serems, the challenge to the public will continue to grow.

Pure Air Systems manufactures a line of HEPA and Carbon based, fan powered air filtration systems. These range in capacity from 50 CFM to 2000 CFM. These all metal units utilize the latest in variable speed motor and digital controllers to meet any application.

Covid-19 Cases Rising

You can either put you head in the proverbial sand like the Ostrich and believe this is not a problem or grasp the real issue of this virus being around forever and changing and adapting to the new vaccines that are currently on the market. Too many people use other methods of gathering data, especially social media, on health care issues rather than from their medical professionals. This never ceases to amaze me.

Viruses are extremely small and very light and can travel up to 20 feet or more when expelled from a human mouth. While we realize many of the face masks are not capable of removing all of the viruses, they are a great barrier non the less. 

The use of air filters in your home or office are minimally capable of removing very little of the airborne viruses. The only air filters that can do that are HEPA filters and those are normally used in hospitals, surgery rooms and chip manufacturing. However, there is a company that has been around for over 37 years that makes a HEPA air filtration system that can be attached to any HVAC ducted residential system and even used as a stand-alone unit. 

Pure Air Systems has been making commercial grade HEPA and Carbon based air filtration units since 1985. These units range in air flow capacity from 50 CFM up to 2,000 CFM and come in seven different configurations. Over the past 37 years these units have been used in a wide range of air  filtration applications around the world. Pure Air Systems is now one of only 3 companies in the world that make this type of fan powered, HEPA based air filtration system.

Designing Your House With Air Filtration In Mind

People that are either building their first home or third home are always concerned with the interior room sizes, placement of rooms, wall treatments and appliances needed to make their home comfortable and livable. Unless they have had heating or cooling issues with an existing home, people rely on their contractor to put in the adequate cooling and heating systems and seldom think about the air filters or air filtration systems installed in a new home.

Most new homes are much tighter ( in regards to air leakage ) and a positive pressure door test is usually done to ensure that when the HVAC system is operational the home is slightly positive. Meaning air is being pushed out rather than being sucked in. Air filters are normally placed in the air returns that are normally located in most rooms, except the bathrooms. These general duty pleated filters are designed to keep most large airborne dust from entering the HVAC system and have very little resistance so they don’t put a strain on the main blower/motor assembly of the air handler. 

Since the air handlers are designed for the general duty air filters, placing a more restrictive, yet more effective air filter media, in the returns will reduce the fan power and pull less air through your HVAC system that could significantly affect the performance of your HVAC system. Therefore, you need to talk to your contractor prior to putting in your HVAC unit if you want to incorporate a more effective air filter system.

Usually the HVAC contractor will caution you about putting the more restrictive filters in your system and suggest a main air filter unit ( either electronic or media filter ) at the inlet to the air handler itself. This can be difficult and often creates installation issues and accessibility to the unit for servicing.

Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985 and has developed a method of attaching one of their HEPA Shield units in a partial by-pass installation that allows the filter to pull anywhere from 600 CFM to 2000 CFM of air through the air filter and then putting back into the HVAC unit. By pulling only a portion of the air the HEPA Shield unit can clean all the air in the house from 24 to 48 times a day depending upon the frequency of operation of the HVAC unit. And, you can still place the general duty filters in the air returns.
