SECTION 4
Filter Element Servicing
4.1 General
To insure proper function and maintain a high level of filtration efficiency, great care should
be taken when handling the element. The element is most likely to be damaged during
servicing than in operation. Special care should be taken when removing and reinstalling the
inlet cowling, as well as when removing and replacing the element from the duct. The
pleated material’s fragile wire mesh is easily damaged or deformed when allowed to scrape
against other objects. Careful attention to the following section will assure full service from
the filter element.
4.2
Removal And Reinstallation of Element
a) Remove the inlet cowl per Bell instructions, DO NOT SCRAPE INLET FAIRING ON
FILTER MEDIA.
b) Loosen the sixteen 1/4 - turn fasteners holding the elements in place and carefully remove
them from the duct.
c) Reinstallation is reverse of above.
4.3
Filter Element Cleaning
a) Holding the element clean side up. Gently tap the element to dislodge any large
imbedded debris and dirt.
b) Use only INTEC filter cleaner, PN 40- 15
Severe conditions:
Soak element, dirt side down, in a pan of sufficient depth to allow
complete coverage with INTEC filter cleaner. Allow soak for 20 to 60 minutes, depending on
condition. Remove element and shake thoroughly to remove dirty cleaner.
Normal conditions:
Spray INTEC filter cleaner liberally onto the entire element for ten
minutes. Alternatively, soak element in a shallow pan of filter cleaner for ten minutes.

CAUTION:
Failure to service the element correctly will harm the filter media by reducing its
filtration efficiency, restricting airflow, and/or a reduction in service life.
