Note

N/A This table contains both forward (+) and backward (-) flow acoustic and aerodynamic ratings based on test results measured in accordance with ASTM E477. Copies of these test reports can be furnished upon request.
Air flow ratings shown include static regain. Therefore if silencers are installed immediately before or after elbows, transitions, at the intake or discharge of the system, or without duct, allowance to compensate for such conditions must be included when calculating the operating pressure loss thru the silencer. Failure to make allowance for these conditions can add several velocity heads to the pressure loss of the system.
