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.

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.

Only 3 Companies Like This In The World

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.

Heat, Humidity and Your Enviroment

If you live in a part of the country where the summer months bring high humidity along with the heat, then your indoor living environment needs adequate air conditioning to maintain healthy living. 

High amounts of humidity (moisture) will condense out on cold surfaces and can become a breading ground for mold. If the moisture gets into a crawl space or attic area that is not conditioned, this area can also be a potential place for mold to grow. 

Aside from efficient air conditioning, the home envelope should be under positive pressure. This means that when the HVAC system fan is running, the air pressure inside the home should be slightly higher than the external air pressure. This ensures the home will always be expelling a small amount of air and keeping outside moisture, heat and humidity from entering the home. If the home air balance is not correct, the negative affect of outside air intrusion into the home will far outweigh a good heating/cooling system.

In addition, good filtration should be part of your HVAC system. Whether you use good filters on the return air grills or a good media filter at the fan unit, filters can significantly minimize the levels of airborne dust and the potential for mold build up on interior surfaces.

Pure Air Systems Still Use All Metal Housings

Pure Air Systems began its journey in 1985 producing one of the first true, commercial grade, fan powered air filtration system that could be used in either commercial or residential applications. These units were made from 20 gauge mild steel that is powder coated for a durable, long-lasting finish. 

Today, the line up of 7 different systems made in variations in both size and air flow design are still made from the same high-grade 20 gauge powder coated steel housings now using the latest iteration of the variable speed drive motors that are digitally controlled. The HEPA filters are all 99.99% efficient at .3 microns and larger and the prefilters and carbon filters come standard with each unit. 

The HEPA Shield systems come in air flow ranges from a low of 50 CFM from our portable unit up to 2,000 CFM on our largest model 2000HS unit. These systems can also be modified to be attached to an existing HVAC duct work system or as stand-alone units. 

Pure Air Systems are all made here in the USA with most of the components manufactured in the US. Some of the original units are still in operation and the average longevity of any of the systems is better than 15 years. Making the PAS units one of the best economical purchases for any air filtration system on the market today.

The Price You Pay For Performance

Amazon and other online stores have created a scenario where people look at items that seem to be similar with various pricing. This has led people to believe that all products are similar and price becomes the deciding factor. For the manufacturers of these products it is difficult to up sell the their products. People will typically go to the best priced selection and read some reviews then make their choice. It is for this reason that many of the companies that make high-end products or products with proven superior performance elect not to market their products on Amazon and other similar online websites. They, instead, market them on their own websites.

So, for the astute buyer, often times you are better served to purchase the products from your selected company product website. They may charge a little more and often don’t offer free shipping, but their products are usually far superior and will last and perform better than many of those lesser expensive copies from your favorite online store.

Pure Air Systems has been offering their products online since 1990. Their commercial grade, fan-powered HEPA air filtration systems are some of the best in the world. With an average operating time of 15 to 20 years, these made in the US systems perform as advertised and the service from PAS is second to none.

AI, Becoming The Next Great Employee

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.

US Designed – US Made – Pure Air Systems

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.

3D Printing Becoming New Way To Make Everything

3D Printing or Additive Manufacturing as it is called in the commercial market, has moved into almost every facet of manufacturing from small replacement parts and dental fittings up to Aerospace and Military applications. There are very large 3D printers making boats as well as printing houses and large structures and small bridges.

3D printing has a number of advantages including the ability to try the “what if” and prototyping of new design concepts. In addition, the materials available for the metal printers has moved this process in the main stream of manufacturing. 3D Printers take up much less space than traditional CNC machines and other fabrication systems and require fewer people to complete the manufacturing process.

One of the main advantages of using 3D manufacturing is the ability to get younger people to become more involved with manufacturing. The younger generation is very familiar with and is good at using CAD type software for design and 3D printing of parts. In truth, the ability to make things using 3D printing or Additive Manufacturing is not considered manufacturing to the younger generation. This is important as they are not interested in moving into the old type of making things. 

Pure Air Systems, an air filtration company started in 1985, has bee using some 3D printing processes for prototyping new parts for their metal housed HEPA based air filtration systems. This helps them more quickly determine the correct part design and more quickly complete the final design and get into production with minimal cost.
