Ambient air filtration can be used by itself or in combination with source capture to collect residual contaminants not captured by the primary system. Ambient systems are especially valuable when:
- Overhead cranes or other facility constraints make source capture impractical
- Working on large parts that cannot be hooded or enclosed
- Dealing with nuisance fumes or particulate throughout the facility
Ambient filtration works on the “dilution” principle (you may have heard the mantra, “the solution to pollution is dilution”). By continually filtering air in the facility, the system reduces contaminant concentrations to safer levels. The goal of an ambient air filtration system should be to keep concentrations of contaminants below Permissible Exposure Limits (PELs) or Threshold Limit Values (TLVs) set by regulatory bodies (Like OSHA) or scientific organizations (like NIOSH or ACGIH). (More on Exposure Limits.)
Our ambient air filtration systems reduce environmental emissions to help comply with EPA regulations and capture contaminants for safe disposal, rather than sending dirty air into the atmosphere.
