SECTION 6
AIR FILTER
STANDARD DUTY AIR FILTER (FIGURE 6–1) – Ser-
vice and replacement instructions are given in the fol-
lowing sections: Filter Element and Filter Element Life.
Filter Element – The element should be serviced when
inspection indicates an accumulation of dirt on the out-
side of the element. Clean every 100 to 500 operating
hours depending on dust conditions. Inspect every few
days until experience determines the proper time inter-
val for servicing.
To Service:
1. Remove element from 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 element.
3. Inspect for rupture by placing a bright light inside
the element. The slightest rupture requires re-
placement of the element.
FIGURE 6–1 – STANDARD DUTY AIR FILTER
Filter Element Life – The element should be replaced
after eight cleanings or if visual inspection indicates a
rupture, crack or pin hole in the pleated media. Inspec-
tion should be done by placing a bright light inside the
element.
Do not oil this element. Never operate
unit without element. Never use ele-
ments that are damaged or ruptured.
Never use elements that won't seal.
Keep spare elements on hand to re-
duce downtime. Store elements in a
protected area free from damage, dirt
and moisture. Handle filter parts with
care.
