2.

Pressure drop through a filter with a freshly
cleaned element is below three (3) inches (76
mm) of water with the compressor running at full
load – this would indicate a rupture or crack.

Inlet Tube – Inspect the inlet screen and tube for dirt
accumulation each time the filter is serviced. Clean the

tube when required by ramming a clean dry cloth
through the tube. Wipe the inside of the filter body to
remove any dirt falling from the inlet tube before rein-
stalling the element.

Causes of short element life include: severe dust
conditions, infrequent servicing, improper cleaning, or
contamination by oil or chemical fumes.
