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.

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.

When Pure Air Systems was established in 1985, there were a number of companies selling HEPA like and HEPA type air filtration systems. Many of these were used in the Asbestos Abatement projects that were prevalent at that time. In fact, Pure Air Systems was a spin-off from HEPA unit designed for abatement but never got into production.

The model 600H unit was a unit with a prefilter, carbon media filter and true commercial grade HEPA filter with a 1/3HP GE motor and Lau Blower. It was in one large section which was subsequently broken into two sections. This was the beginning of the PAS Line of HEPA systems. 

As the popularity of the 600H unit grew, PAS introduced the new ECM motors from GE to make the HEPA system available as a stand alone unit as well as using variable speed motors that were then being introduced by all the HVAC companies.

By 1999 PAS had grown the line from one unit to seven different systems including the new portable unit. It has also moved into a new 9,000 square foot building. As of this date, 90% of the units are still built with parts made in the USA and it is now one of only 3 companies in the world that make this type of HEPA with the size and flexibility in size range and air flow control.

HEPA filters are the best method of removing sub-micron airborne contaminants including, viruses, bacteria, dust particles and airborne allergens ( mold, pollen, etc.).

One of the challenges of using HEPA filters in a residential application is how the HEPA filter is installed to best gather the greatest amount of airborne particles from all rooms of the home. Most air filters in residential HVAC systems are either placed in the air returns for each room or one largepr filter is placed at the return air inlet of the main HVAC fan unit. 

Since HEPA filters have a much higher resistance to air flow than standard duty air filters, they need to be placed in a cabinet that includes its own blower/motor section to assist the air flow through the HVAC system so there is no disruption to the air flow from the HVAC unit. 

Pure Air Systems developed a HEPA filtration system that incorporated its own blower/motor unit along with a true commercial grade HEPA filter, prefilter and carbon media filter. This metal framed housing unit could be attached to the return air side of the HVAC system in what is called a “partial pass” concept. In essence, the HEPA system would pull anywhere from 600 CFM up to 2000 CFM of the return air ( the later used mostly in commercial systems) and then return it back into the HVAC system on the supply side. In this manner the HEPA system would clean all the air in the house after the 3rd or 4th pass. Or, approximately 30 to 50 times  day, depending on how often the HVAC fan system runs.

The PAS units all utililze the newer variable speed drive, digitially controlled motors that can be programmed to operate in sync with any HVAC system.

I have been playing around with the new Google AI app, Bard. It is fast, and easy to use. Further more, it will create anything you ask it to create. The more and better the prompt information you input, the better the end result. I have already used it to write some simple contracts. 

In the field of engineering, AI apps are helping entrepreneurs and manufacturing and design companies to both enhance existing designs and fabrication techniques but also developing whole new concepts is product development. And while there are skeptics out there who believe AI is the end of the world as we know it, this technology is growing so fast that in another 3 months it will become ubiquitous in the field of writing and creating everything.

ChatGPT and other AI apps are gaining popularity and there are now more than 15 of these apps out in the market place. Yes, students are using it to write term papers and do math problems, and this can be an issue down the road, but it also ushers in a new way to increase the speed of creating everything and with fewer employees. This concept has not been lost on major corporations who are already looking for individuals with some experience with these new computer models.

Pure Air Systems has been manufacturing commercial grade HEPA based, fan-powered air filtration systems since 1985 and will begin to utilize this new technology for enhancing its product line as well as writing some of its marketing materials.

Almost 80% of the products purchased on-line from Amazon, Walmart, Ebay and other web based stores, are manufactured in other countries. The majority being made in China. However, many of these products, including Apple iphones, etc, say they are designed in the US but made overseas.

Pure Air Systems has been designing and manufacturing their fan powered, commercial grade, HEPA air filtration systems since 1985. While some of the motors are now made overseas, over 90% of the components that make up the filtration system are made in the USA. These units have shown to be some of the best on the market and many of these systems are still in operation after over 20 years of service.

It is more expensive to purchase components and parts made in the USA and often times a wider selection of component and part types are available from outside the US. Manufacturing is a very challenging process and requires a lot of up front capital to obtain the machinery and skilled labor to make almost anything.

Pure Air Systems continues to look to the US companies to make any new components or parts that are needed for the existing and newly designed units. While these may be more expensive it is important to continue to use parts made in the US to keep these manufacturing operations viable.

Discussions about AI have been around for the past 20 years. However, the ability to use the new AI apps and software to enhance, modify, alter, create and change everything. The new platforms can revolutionize the time it takes to write books, create paintings, develop formulas, and enhance all forms of social media. 

In the area of manufacturing, AI can assist in creating the most efficient way to make an object or select better materials and manufacturing methods to accomplish a task in half the time with less material usage. Companies that utilize this technology will be far ahead of the competition. For all the naysayers and podcasters that are out there down playing AI’s role in the future, the truth is that this technology will very quickly become mainstream before the end of 2023.

Pure Air Systems, a 37 year old company, manufactures a high end line of commercial grade, fan powered, HEPA based air filtration systems and is strongly considering utilizing AI to make changes to its design to cut material and production costs. As the price of all components continue to rise it is becoming more important to utilize all the tools available to maintain the bottom line and scale up the business. AI is one of these tools.

Our eyes allow us to focus on and see airborne particles as small as 20 microns. For comparison, the human hair is about 100 microns in diameter. Most bacteria are in the range of less than 1 to 5 microns in size and viruses are less than 0.12 microns in size. So the old adage that what you don’t see won’t hurt you is not correct.

Bacteria, when present in a warm, moist environment, can stay alive for very long periods of time. From many hours to days. Because it is heavier than viruses it will not stay airborne for very long. So most contact with bacteria comes from contact with a surface or body part that caries the bacteria.

Viruses, on the other hand, are very tiny and light and can stay airborne for long period of time. This is how the flu and cold bugs are normally transmitted. Coming in a room or close contact where these viruses are airborne can infect another human once the viruses are inhaled and ingested. This is the reason masks are used in all medical facilities, especially surgical units.

The Covid issue has been dissected by everyone in every discipline including social media. The fact remains that Covid is virus and like all other viruses it is extremely small ( less than .012 microns in size ) and easily transmitted through the air. While the various types of face masks that are available are not truly capable of removing 100% of the airborne viruses, they can significantly minimize the levels of virus ingestion. 

In 1985 Pure Air Systems introduced an air filtration system utilizing true, commercial grade HEPA filters for the residential and commercial markets. These fan powered systems are capable of either being attached to existing HVAC systems or stand-alone. 

HEPA filters are used in all hospital surgery suites, laboratories, pharmaceutical companies, chip manufacturing and more. These filters are specially designed to remove airborne particles as small as viruses and are extremely efficient over their life. The type of filter media used in the HEPA filters is partially copied in some of the new face masks now on the market. Then N95 mask is one of them.

It is important to know that the viruses that are now out in the world are extremely capable of changing and adapting to new drugs and pharmaceuticals, therefore making them around as long as we inhabit this planet.

Starting a business today is easier than it has ever been. Running it and keeping it a float is another. Longevity in businesses today is no longer the norm. Companies are born, merge, change direction and die faster than ever before, so having a company stay in business and keeping it on a positive revenue stream for 30 plus years is no easy feat. 

Pure Air Systems was started in 1985 by Don Musilli, and was sold in 2006. The concept of manufacturing a high end, fan powered, commercial grade, HEPA air filtration system that could be used in almost any configuration was very foreign in 1985 but the concept, the quality and performance of the systems allowed us to continually increase our market share.

Over time, Pure Air Systems added more products to its catalog and eventually ended up with 7 different systems allowing for complete penetration into the commercial and residential markets requiring high end HEPA based air filtration systems. The addition of the ECM, variable speed motors in 1999 provided an entry into the over seas market allowing us to offer 120/240 volt 50/60 Hz motors for all of our systems.

Pure Air Systems learned that feedback from its customers was important and responding to the feedback in the way of modifications to the systems was essential in growing its business. Keeping the same quality even though prices increased was necessary as people are quick to switch companies when something doesn’t work like it should. Losing customers is easy….keeping customers is hard.

Pure Air Systems is now 37 years old. That puts it in rare company these days especially for a manufacturing operation. The adage of “adapt or die” is very true today and “modifying, changing and altering” your operation to meet the changing needs of the market is critical in keeping your company moving forward and growing.
