Stoddard F64 and F72 intake filters and filter-silencers

The Stoddard F64 and F72 intake filters and filter-silencers are designed to mount directly on the inlet of a blower, compressor, or engine.  They provide 16dB to 20dB noise reduction.

The housing of the F64 series and F72 series are the same; the only difference is the filter element inside.  The F64 models have a paper filter element by default but can also be specified with a felt or wire element.  The F72 models have a polyurethane filter element.  If you have either a F64 or F72 filter you can replace the filter element inside with any of these four options.

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.
