How would you like to know exactly when to change your filter You can with the GeneralAire Filter Gage and Remote Installation Kit. Home air filters capture a large amount of contaminants and can become clogged easily. Though many filters may have a suggested rate of replacement, that can vary depending on several different factors. For example, rate of airflow, types of particulates, and the concentration of indoor air pollution in your house can all have an impact on how often your filter should be replaced. Because air pollution can cause or worsen breathing problems and other health problems, it is important to know exactly when to change your filter.
How Does the Gage Work
The G-99 Air Filter Gage provides a visual indication of when your HVAC filter should be replaced. The gage is installed between the blower and the filter where a slight vacuum exists due to the airflow 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 gauge 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 gauge. Mount the gauge in alevelposition with the pressure sensing tube projecting into the blower compartment.
