Section 1: Introduction to Fan Systems 1 For the purposes of this sourcebook, the term “fan” will be used for all air-moving machines other than compressors.
Section 6 Particulate Matter Controls
www3.epa.govParticulate matter (PM) is the general term used for a mixture of solid particles and liquid droplets suspended in air. U.S. EPA defines PM 10 as particle matter having a nominal aerodynamic diameter of 10 micrometer ( µm) or less. PM 2.5 is defined as PM less than or equal to 2.5 µm in aerodynamic diameter. In general, “coarse PM” refers ...
