TheRangeRelief™ Rangehood Pressure Relief Control Switch works with any AirCycler® motorized damper-based system to provide automatic rangehood pressure relief. By simply installing theRangeRelief™ Pressure Switch with the already existing motorized damper,RangeRelief will open the damper allow...
The compensator maintains system pressure between 18 and 33 psi. The inlet check valve controls the hydraulic fluid flow rate into the damper to 70 cu in/min at 50 psi. It also controls the fluid that leaves the damper to 14 cu in/min at 3750 psi. The relief valve protects the compensa...

it may also be possible to include an air pressure relief damper on, for example, the return air duct, or in the wall of the refrigerated space to make sure the refrigerated space does not get over pressurized. The control described above may be used to adjust the return air and outside...
and controls so that the air returned from the individual rooms or areas supplied by the fan is returned via the related return air system . Normally this will involve closing an outside air damper to the minimum position, opening the return air damper, and closing exhaust air and relief ...
