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.

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.

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.

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.

Air Filtration 101

The use of air filters for removing airborne particulates has been around for over 100 years. Today’s filtration technology is eons ahead of just using cheese cloth to filter our particles for fan powered device. The newer, blended filtration medias are much better at capturing small, sub-micron particles with higher capture rates and lower pressure drops over time.

Air filters range in efficiency from general duty, like furnace filters, to high capacity, high efficiency, like HEPA filters. For most home applications the general duty filters are used as they both help keep the cooling coils in the HVAC system clean as well as minimize the dust in your home. 

The higher efficiency filters, like HEPA, are used mostly in commercial applications like hospitals, clinics, surgery suites, chip manufacturing, clean rooms, laboratories and more. There are also HEPA based systems available for the residential market that utilize their own fan/motor system to augment the blower/motor assembly in the HVAC unit. HEPA filters have a much higher resistance to air flow but can capture particles as small as a virus. 

It should be noted, that the use of non-mechanical filtration devices such as ozone generators or electronic air cleaners are not really that effective at removing particles from the air. Ozone generators are really more effective on the reduction of airborne gaseous contaminants and electronic air cleaners need constant cleaning to make them work.

The Best HEPA Filtration System Line-Up In The Market Today

Founded in 1985, Pure Air Systems offers one of the most complete line-up of HEPA air filtration systems anywhere. In fact, there are now only three companies in the world, including Pure Air Systems, that offer fan-powered, high-performance true HEPA filtration systems in the world. 

PAS currently uses variable speed drive motors in all of its filtration systems and that now includes the HPS series portable units. Unlike the older style induction motors, the variable speed drive motors can be programmed to run at any speed and are capable of ramping up if the pressure drop across the HEPA filters increases. This allows for a constant flow of air ( measured in CFM ) through the filtration systems over the life of the HEPA filter.

The all-metal housing units also include a prefilter and carbon filter along with the scanned HEPA filters. There are three base units, the 600HS, 1200HS and 2000HS units along with the HPS portable series. The housings for the base units are split into two sections, with one section containing the blower/motor and the other section containing the filters. By modifying the sections we can offer straight through units, or left or rignt 90 degree angles and also change the type of filters that are put into the units. This design technique allows us to offer a unti to fit any configuration whether the units are installed as along with existing duct work or as stand alone systems.

Crossing Over

The acceptance by some individuals that when we leave this earth we cross over to some other dimension or plane. Our souls moving among those other people that have crossed over and suspended in some semi-purgatory state. Absolute belief in what happens to us when we cross over is often based on centuries of superstitions that morph from story to fact.

Today, crossing over also refers to those individuals who are moving from country to country to find some form of normalcy. It is a very challenging and global problem that has more challenges than answers.

Companies often find it difficult when they try to cross over to a different market, demographic or geographical area where they are not recognized or have any specific customer base. Being successful in one’s back yard was never a guarantee that across the bridge and over the river would carry your name without difficulty. Great to be optimistic, better to be realistic.

In 1985, Pure Air Systems started a company to make, market and sell a commercial grade HEPA filtration system in one single market. Small amounts of success prompted the company to reach outside its geographical market and through the use of the internet and a growing line of high performance systems the company crossed all borders including the two oceans to make Pure Air Systems an international brand. Of course this only took 31 years, but making those strides was worth the wait.

PAS is the leader in high performance, fan powered, commercial grade HEPA and Carbon based air filtration systems in North America. Their systems use variable speed motors and they can produce from 50 CFM to 2000 CFM in 1% increments. In addition, these systems can be used either attached to ducted HVAC systems in a partial by-pass mode or they can be used as stand alone units.

The systems are used in a wide variety of markets including, commercial, institutional, industrial, medical and residential. The important fact to understand about the systems made by PAS, is they only make one grade. That means that Mrs. Smith in Arkansas gets the exact same 600HS unit that GM uses in their R&D laboratory in Detroit. There are few companies in this country that can say that and mean it.

Politics Is A Noun

With all the action now taking place on TV showing every candidate from both parties vying for the Presidency, one would think that all the rhetoric about what each candidate will do for the US when elected we would have one of the most progressive governments in the world. Unfortunately there is more fluff than reality in the promises made during these primaries. And we should know this as we have heard this song before since the early 70’s; same stuff different day.

The ability to make false promises and still have someone follow you is somewhat exclusive to politics. While small businesses have often done this to their customers it is not something we often see in larger companies and publicly held companies. And the reason is simple. Customers loyalty today is spelled with a small L. If you promise one thing and deliver another in very short order your company will suffer the exodus of customers as they seek to find a more truthful company path. In politics one can easily shift blame to the past office holder or the lack of agreement by the Congress or Senate and in most cases we buy into that excuse.

Pure Air Systems started promising a new way to clean the air in your home, office, factory or medical facility in 1985. Their goal was to provide true, commercial grade HEPA filtration systems using fan powered units capable of moving up to 2000 CFM. Their first attempt to move this commercial use technology into the home market was the introduction of their model 600H unit. Creating a HEPA system that could be used in a partial by-pass configuration designed to fit onto almost any forced air, ducted heating/cooling system was quickly accepted by the heating/cooling industry and customers alike and the continued success of this concept propelled PAS into developing five more systems.

Today, 31 years later, Pure Air Systems is still fulfilling its promises to the customers both old and new to provide the best HEPA and Carbon based, fan powered, commercial grade air filtration systems in the world.
