With US companies continuing to use more off shore operations to manufacture their products, the quality of some of these products has become suspect. Where a company once used heavy duty metal construction they now use high density plastics and other non-metalic components to fabricate the end product. In some cases the substitute materials are better, but in many cases they are not.
In the air filtration and air purifying market the trend has been to use lighter, less expensive plastic type materials especially for powered devices. For throw away air filters the use of cardboard frames is still the norm as plastic is more expensive. For some residential applications the use of plastic materials is appropriate as these devices are not usually subjected to harsh environments although they are often placed in unconditioned areas. For the commercial, industrial and institutional markets, however, the environments can and usually are much more challenging.
Pure Air Systems, has been manufacturing high end, commercial grade, HEPA and Carbon based air filtration systems since 1985. From the beginning PAS used nothing but steel for the fabrication of their products. Even the new portable unit now available from PAS is fabricated from steel and the complete product line uses a powder coated paint process to ensure durability in any environment. To be sure there are very few, if any, other filtration companies that use this type of construction for their products.
In the majority of non-residential applications the PAS systems are mounted in and around the heating/cooling air handling systems. In many cases they are used as stand-alone units. Often they are located in non- heated or cooled environments and many times they are located outside. And, in the case of many manufacturing and process facilities, the environments can be caustic or contain gases that can etch or destroy plastic type materials. In thousands of installations in these types of environments the PAS product line has proven to be one of the most reliable and durable filtration systems available on the market today.
Aside from the durability of the product line the overall effectiveness and efficiencies of the HEPA and Carbon based units are second to none. Pure Air Systems makes some of the most powerful, high volume commercial grade, digitally controlled systems on the market today. And because the systems’ variable speed motors are rated 120/240 volt, 50/60 Hz, they can be used anywhere in the world.
Even for those applications in the residential market, the steel construction of the PAS product line offers some major advantages over the plastic type filtration device construction. Many of the PAS 600H and 600HS models, for example, that were sold during the late 1980’s and early 1990’s are still in operation today. Other than changing the filters on an regular basis and perhaps having to replace a motor after 10 years or so, these systems continue to operate effectively and efficiently.
