The Stoddard Pressure Drop Indicator “filter minder” gauge provides a simple way to monitor your air filters. The vacuum caused by a dirty filter element is sensed in the void formed by the banjo fitting and locking wingnut. The vacuum is transmitted through the fitting and hose to the filter minder which show the amount of vacuum with a yellow bar graph. When the display area is totally yellow (15″ W.C. drop) then a clean filter is required.
After the filter element has been changed, the display can be reset with a button on the bottom of the indicator.

Cleaning your Stoddard Filter Element
Turn off the air moving device prior to servicing. Remove the wing nut on the housing cover and then lift the cover off. Check the filter elements and then service using the instructions below. After cleaning, check inside the housing for loose articles before replacing the weatherhood and restarting the air moving device.
To extend the service life of a Stoddard paper filter, rap the element to dislodge accumulated dirt. Alternately, compressed air (75 PSIG max) can be directed through the element opposite to the direction of air flow to dislodge dirt. These paper filter elements will eventually need to be replaced.
For the polyester felt elements or polyurethane prefilters, wash in sink or large pan using water and any good washday type detergent and rinse clean. Squeeze out filter by pressing it against metal grid. Let stand and allow to dry completely. Felt and polyurethane elements will eventually need to be replaced.
Epoxy coated wire mesh elements should be soaked in hot water and detergent. After the element has completely dried, adhestive (light oil) can be applied at 1.5 to 2 oz.; allow excess to drain off prior to installing. These elements can be used indefinitely.
