Offices that are adjacent to a factory floor are often a problem for the staff that works in these environments. The door that provides access to the factory also provides an entry way for the dust and dirt generated by the factory into the office. When an employee enters the office from the floor he or she may have particles of dust and dirt carried on their clothing especially if this is a machining operation or where there is powdered materials being handled.

Also, if the office is air condition with a central heating/cooling system it is often the case that the office space is under a slight negative pressure when the HVAC fan is running. This compounds the issue by pulling in air from the factory area every time the access door is opened.

One way to eliminate this issue is to place a fan powered, HEPA based air filtration system by Pure Air Systems in the room directly or attached to the return air ducting from the main HVAC system.

The Pure Air Systems unit can assist in both keeping the air clean as well as make the room positive rather than negative. If the unit is placed in the room as a stand alone unit is can bring in a small amount of air from outside to help pressure the area or, use the same concept of outside air introduction if attached to the return air duct from the air handler.

In either case the PAS HEPA unit will significantly reduce or remove a very large percentage of the airborne particulate at an efficiency of 99.99% at 03 microns or larger.  The fan powered systems come in a variety of sizes  ranging from 350 CFM to 2000 CFM units. These systems can be adjusted with the digital controller option to run at any speed from 10 % up to 100% in 1% increments.

The systems use the ECM motors which are rated at 120/240 Volt, 50.60 Hz. So they can be used in any country.
