No more guessing! An easy-to-use, easy-to-read gauge to monitor filter media loading so that filter media may be changed when needed. The gauge 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 gauge, 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.
• Dial design is easy to read and interpret when filter needs to be changed.
• Easy to calibrate for new, clean media.
• Easy installation.
• Built-in filter screen removes dust from sampled ambient air to keep clean.
• May be mounted remotely up to 10 feet from monitoring location (with extension kit shown below).
• Easy to disassemble/assemble for service.
• Low cost
The gauge may be calibrated in a negative pressure range from 0.1 to 0.4 inch w.c. When properly calibrated in this range a vacuum increase of 0.10 to 0.15 inch w.c. will indicate a filter change is necessary.
The installer should be an experienced service technician. When drilling the hole in the blower compartment extreme care should be taken not to damage components within the heating or cooling system.
The gauge must be located where it can sense 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 gauge. Mount the gauge in a level position with the pressure sensing tube projecting into the blower compartment
Install a clean filter and run blower on highest speed. With a small screwdriver adjust the calibration screw, on the face of the gauge, to put the pointer in the clear area in the center of the green “FILTER IS CLEAN” range.

The gauge may be disassembled for service although this should rarely be required because it contains a small filter screen to stop dust from entering the area of the vane. Remove gauge and, from the back, push white plastic clips out with a blunt tool. Remove calibration screw, lift of clear cover and dust all parts with a clean brush. Reassemble and test that the vane moves freely in the gauge. A fresh adhesive strip may be required to reinstall.
