Ambient Air Cleaners involve the use of large “Washable, Cleanable or Replaceable Media” filters. These units, both filter and re-circulate the air back into the work place Installation Configurations: Free Hanging "Negative Pressure" “Race Track” "Cross Dilution" Depending upon the designed air pattern, these systems "scrub" the ambient air of contaminants and the result is a dramatic reduction of airborne pollution. These systems are best used in combination with source-collection equipment.

Some important things to consider when purchasing these types of units:

What is the volume of the room you want to clean? (cubic dimension: L'xW'xH')

How many times would you like to change the air in your room? (eg: Welding=8 AC/H)

How much contaminant do I generate? (eg: dust, smoke, fume)

Where am I going to mount these units?

Can I use these units to create a negative pressure in my work area?

Do I want "throw away", "washable", "cleanable" or "self cleaning" filters?

Ducted Air Cleaners are used in a variety of applications where the filter selection often requires a specific configuration. With these collectors you can select a variety of particulate, liquid or gas phase filters such as “HEPA” filters, “Mist Agglomerators” and “Gas Adsorbers” respectively. These systems are available with or without pre-engineered and installed fan packages.
