- Technical Information
The G-99 Air Filter Gage provides a visual indication of the need to replace the air filters in forced heating and cooling systems. The gage is installed between the blower and the filter where a slight vacuum exists due to the air flow resistance of the air filter. Air flowing into the gage, around the calibration screw, lifts a vane in proportion to the negative pressure in the blower compartment. As the air filter loads, the vacuum increases, raising the vane to indicate a filter change is necessary.
Installation Instructions
The gage must be locked where it can sense the pressure conditions in the blower compartment between the filter and the blower. Select a location on a vertical surface enclosing the blower compartment and drill a 3/8" hole. Remove the protective paper from the foam adhesive strip on the back of the gage. Mount the gage in a level position with the pressure sensing tube projecting into the blower compartment.
