The new import tariffs against China and other countries will make component parts and about 80% of what we purchase, more expensive. There is little truth in the fact that many of the companies that are overseas will now return to U.S. shores. Unfortunately, all the companies overseas are either owned and operated locally or are part of an international partner. For all intents and purposes, the U.S. has pretty much given up on building new manufacturing plants as most larger corporations would rather design products here and have them made somewh   ere else. Or if they are going to manufacture in the U.S. they will be using Robotics and few people. 

Intel, one of the largest and most profitable companies in the world, just stopped production of two huge Chip Manufacturing plants in Ohio because of slower chip demand and the fact they have lost over $186 Billion in their stock. They hired a new CEO and put the plants on hold until 2030. Making anything is very difficult, especially high end tech products. Apple designs their iPhones, etc, but they are all manufactured overseas. 

Pure Air Systems, Inc., an Indiana based corporation, has been manufacturing high end, fan-powered, HEPA based commercial grade systems since 1985. While some of its components are now manufactured overseas, 80% of the systems are made from American made components. And now, after 40 years. Pure Air Systems, is one of only 3 companies in the world that make this type of high end product. It is very difficult to compete in the world market when you are constantly searching for suppliers that can meet your demands at a price that allows you to make a profit.

Even though the industrial market has changed and many products are now made overseas, there are many small, specialty manufacturing operations that are using welders, sanders, chemical processes and semi-cleanroom manufacturing systems.

Most of these operations are done inside of small shops or buildings and all of them require some form of dust or gaseous odor control. The utilization of just using a exhaust fan to the outside is still used but in most cases this is no longer allowed as this effluent is going into other businesses or adjacent homes. In addition, when you are exhausting 300 cfm to 1000 CFM of air from inside the building you are throwing out cooled or heated air and have to replace that with make up air and that is expensive.

Pure Air Systems has been making fan powered, commercial grade HEPA and Carbon based systems since 1985 with air flow capacities from 50 CFM to 2000 CFM. These industrial, metal framed units can be used as stand-alone units or can be attached to existing, ducted HVAC systems. These units can be attached to a hood that is placed over or around the industrial process and capture the exhaust gases as well as the particulate and then have it brought back into the room either through a straight duct or into the existing HVAC inlet to be reheated or cooled.

The PAS units can also be fitted with just all carbon for gaseous fume removal or carbon and filters or all filters depending upon the specific application. This makes these units multi-functional and all filters are interchangeable. The motors are all variable speed, digitally controlled and programmable so you have a lot of flexibility for ventilation if your operation has more or less exhaust air for controlling the effluent.

In 1985 and idea to use commercial grade, fan-powered HEPA based air filtration systems was devised by Don Musilli. The concept of using a large HEPA system in conjunction with a standard, forced air, heating/cooling system was never tried before. Normally, contractors just installed a standard pleated air filters or in the early days they used electronic air cleaners, which never really worked that well.

When Pure Air Systems was formed it was a long work in progress and working out of a home office with one old computer and the first use of what was to become the internet as we know it now, but then it was primarily only a landing page and you either used AOL.com or Yahoo.com. Both start-ups. Years later as PAS grew we formed our own URl and found that the use of the World Wide Web had become a very important part of our marketing program which provided almost 60% of our sales leads. 

10 years later after working out of our home and garage we finally had enough money to purchase some land and build a 9,000 square foot building and starting designing different sized units and our sales started to really grow as we added some systems that were four times the size and power of our original 600H unit. By 1999 we started to use the new GE ECM variable speed drive motors that were capable of running at any speed and could be used anywhere in the world. 

By the early 2000’s we had developed 7 different systems that could be used either as stand-alone units or attached to an existing HVAC system and for almost any commercial, industrial, consumer or institutional application. We had to develop a new way to package the units as we had decided to divide each unit into two sections. One housed the blower/Motor and controls and the other half had the three filters. A polyester ring panel prefilter, a carbon media filter and a true commercial grade, certified HEPA filter. We could also use higher grade SULPA  filters for certain applications.

In 2006 Pure Air Systems was sold to Dave Hearns who continues to provide the same high quality systems that now incorporate programmable ECM motors with customer options to change the system air flow and time to run on the fly.

Searching for that special tool or clothing article on Amazon you will find hundreds of options with tools and clothes of many styles, materials and designs. One would think that with all those choices that some of those items would be made right here in the USA. While many items do not indicate their country of origin, when your Amazon package is delivered and the product is removed, 99% of the time made in China or some other foreign country is stamped on the label or item itself.

With the exception of most medical equipment, some machinery, autos and airplanes, the majority of everything else we use in our daily lives is made outside the US or with some components from outside the U.S. It has become more expensive and more challenging to compete with products from other countries as they have greatly improved their technologies or developed something we never made in the US. OLED TV’s are an example. All of this technology was developed in South Korea.

The US has lost most of its’ experienced automotive, aerospace and scientists to old age and retirement. The newer generations are much more into the digital markets such as AI, AR and VR headsets, cell phones, computers for gaming, specialized sports equipment and some new automotive technologies.

Pure Air Systems, was started in 1985 selling modified HEPA based air filtration systems for the residential market and over the past 39 years is had added 7 new systems to its line of high end fan powered air filtration systems with 90% of the components being made in the US. Their systems are now sold all over the world and they are one of only 3 companies in the world that currently manufacture these types of systems.

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.

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.

Removing odors and gaseous pollutants from any environment is much difficult than removing airborne particulate. There are a number of air filter types that can easily remove airborne dust, but the removal of airborne odors and gases requires some very specific materials that can effectively adsorb these organic or inorganic molecules.

The most common material used to remove odors is activated carbon ( charcoal) which comes in a number of sizes. The most common is cocoanut shell carbon that is usually around 1/4″ in size and is often enclosed in a mesh type material or sometimes in a fine opening screen container. Carbon can be used in both air and water for the extraction of gaseous pollutants, making it one of the more popular materials on the market.

When cocoanut shells are placed in a high temperature oven under pressure it expands the surface area of the material and then makes it into a carbon material. The expansion to the shell gives the material a very high surface area and the ability to adsorb up to 100 times its own weight in gaseous pollutants. This means that a small amount of carbon material can remove a large amount of the odors and last a long period of time. 

Pure Air Systems has been manufacturing HEPA and Carbon based, fan powered, commercial grade air filter systems since 1985. The various systems available from PAS include carbon media as a standard part of the filtration unit along with a prefilter an HEPA filter. In cases where a customer only has an odor or gaseous pollutant issue, Pure Air Systems can remove the HEPA filter and replace it with an all carbon bed of material. Depending upon the odor challenge, the systems can hold from as little as 8 lbs of carbon up to 60 lbs of carbon material. And the air flow capacity of the systems range from 50 CFM to 2000 CFM.

Carbon that is used for odor control if often made from expanded cocoanut shell carbon. This type of carbon has a high surface area and very high ratio of molecular adsorption to weight of carbon. This makes this material suitable for both adsorption of organic and inorganic odors and gaseous pollutants in both air and water applications.

For general odors found in most homes; typically pet, cooking and carpet odors, carbon filters placed in the HVAC system will be capable of removing about 50% of those odors with a replacement cycle of once every two months.

For commercial and industrial applications, it may be necessary to use large carbon beds, 10 – 20lb pads of carbon, to significantly reduce the the gaseous pollutants. And, in some cases, a catalytic material like zeolite may be required to enhance the adsorption of the gaseous pollutants. Depending upon the amount of pollutant being released it may be necessary to replace these carbon pads as often as once a week. 

Odors such those produced by cigarettes are some of the most difficult to remove as the nicotine smoke produces a sticky residue with adheres to almost any surface and releases that odor for long periods of time. Carbon can help in these cases but replacement of the carbon can be up to once a day.

The removal of gaseous pollutants ( odors ) is often accomplished by using a masking agent sprayed into the room or area with the odor. If the odor is temporary or infrequent then the aerosol spray deodorizers will usually meet the task. If, however, the odor is from a continuous source and is strong enough or dangerous to breathe then commercial grade carbon media filters will be required.

The use of expanded carbon ( charcoal) for the reduction/removal of airborne gaseous pollutants has been around for over 100 years. These carbon media packs ( usually 1 inch to 4 inches in depth) can be very effective at removing these strong, continuous odors and the carbon can be combined with other materials to catalyze some pollutants that are not removed by just carbon alone.

Pure Air Systems, has been manufacturing HEPA and Carbon based, fan powered, commercial grade air filtration systems, since 1985. These metal framed units incorporate the newer variable speed motors and the air flows range from a low of 50 CFM up to 2,000 CFM. PAS offers a wide range of sizes and configurations to fit any specific need. Some of the large units can hold up to 80 lbs of carbon media or applications where high concentrations of gaseous pollutants are present.

With over 13 years of experience in using FDM and FFF 3D style printers one learns quickly the various quirks in the operation of these printers. While they have improved dramatically since the 2011-2012 introduction of desk top printers, there are still some challenges when printing with various filament types. To be specific, ABS ( Acrylonitrile Butadiene Styrene ) has been one of the more popular materials with which to print. However, this material off-gasses when printing at 245 Degrees C and above and the odor can be quite significant. In addition, the gases produced along with some of the fine particles released during printing can become a health concern if not properly vented or isolated when printing occurs.

One of the other issues when printing with ABS is the layer separation that can take place if the object being printed cools to rapidly during the printing process. To minimize this issue you need to enclose the printer and keep the cold air drafts from falling on the printer bed. This enclosure can also also double as a mechanism to reduce the entry of the odors and particulate into the room. The use of a fan powered exhaust system attached to a vent in the enclosure along with a carbon media and HEPA filter will allow for continued use of the printer inside any room or enclosed area without compromising the environmental integrity of the room.

Pure Air Systems has been making fan powered HEPA and Carbon medial filters since 1985. These systems are designed to move from 50 CFM up to 2000 CFM with the ability to control the air volume in 1% increments. These metal framed units come in seven different configurations with the addition of a portable unit that is a prefect fit for the enclosures that would be placed over the 3D printers.
