HEAVY-DUTY AIR FILTER (Figure 6-1) furnished as standard equipment on units with an enclosure is a heavy-duty washable element dry type air filter.

The air filter must receive proper maintenance if maximum service is to be obtained from the unit. Establishing adequate and timely filter service is MOST IMPORTANT. An improperly maintained air filter can cause a loss of compressor air delivery.

Filter Element – The element should be serviced when inspection indicates an accumulation of dirt on the outside of the element. Clean every 100 to 500 operating hours depending on dust conditions. Inspect every few days until experience determines the proper time interval for servicing.

1. Remove the element from the filter housing.

2. Blow off excess dirt with air nozzle. Direct air blast parallel to element pleats at a slight upward angle. Do not point air blast directly at the element.

3. Elements contaminated with dry dirt only:

(a) Mix a sufficient amount of warm water and household detergent to allow the element to be fully submerged.

(b) Place the element into the cleaning solution and allow to soak for five minutes. Agitate in solution for two more minutes. Elements contaminated with oil or greasy dirt deposits:

(a) Mix a sufficient amount of the following cleaning solution to allow the element to be fully submerged. To one gallon of lukewarm water add four tablespoons of mild house hold detergent and one–half teaspoon of trisodium phosphate. Mix well.

(b) Place element into cleaning solution and allow to soak for five minutes. Agitate in solution and allow to soak for five minutes. Agitate in solution for two minutes and remove.

Warning: This maintenance check requires trained personnel with PPE!
