The GeneralAire G99 Ventilator Filter Gage is an easy-to-read and easy-to-use gage that monitors the ventilator filter media loading so that your filter can be changed when needed. The air that flows into the gage around the calibration screw lifts a vane in proportion to the negative pressure in the compartment of the blower. As the air filter loads, you will notice that the vacuum increases, that helps to raise the vate to indicate that a filter replacement is necessary.

This GeneralAire Ventilator Unit Air Filter Gage features a dial design that is easy to interpret when your filter needs to be changes. Calibration and installation is easy for a new, clean filter media. The built-in filter screen removes dust from sampled ambient air that helps to keep your air cleaner filter gage clean. With the extension kit, the GeneralAire G99 Gage can be mounted remotely up to 10 feet from the monitoring location. This filter gage is easy to assemble and disassemble when servicing is required.
