First-stage filtration for DeVilbiss systems

The DeVilbiss 190727 is a first-stage replacement filter rated at 5 microns. It fits the HAF-6 housing used on compatible DeVilbiss air compressors and vacuum pumps. This part is intended for technicians and owners performing scheduled maintenance on those units. Buyers needing a different micron rating or a second-stage element should verify the correct part number before ordering.

Normal pressure drop and service life

In normal use the filter removes particles down to 5 microns while maintaining adequate flow for the compressor or pump. Pressure drop increases gradually as the element loads with contaminant, signalling that replacement is due. No unusual noise or power draw is associated with the filter itself; the driving unit operates at its usual sound level and electrical consumption.

Direct-fit replacement with no extra parts

The filter ships as a direct replacement for the original HAF-6 first-stage element. No additional gaskets, adapters or tools are included or required for installation. Orders of $75 or more ship free from the manufacturer. The package contains only the filter element, so installers should reuse existing housing hardware.

Questions about this item

How do I install the DeVilbiss 190727 1st Stage 5 Micron Filter HAF-6 and what step is commonly missed?

Thread the filter into the first-stage housing by hand until the gasket seats, then tighten one-half turn with a wrench; the step often missed is lubricating the gasket with compressor oil to prevent leaks.

What maintenance or replacement will the DeVilbiss 190727 filter need over time?

Replace the element when the pressure drop across the filter exceeds the compressor manufacturer's limit or at the interval specified in the compressor manual, whichever comes first.

What limit appears first on the DeVilbiss 190727 filter during sustained use?

The 5-micron media loads with particulates and oil aerosol, causing a rising pressure drop that eventually restricts airflow to the second stage.
