Air filters should also be checked occasionally to make sure they are not obstructed or
damaged.
For replacement procedures, refer to
Replacing the Fan Filter on page 137
.
If the filter is undamaged, proceed to clean it. There are several methods for cleaning the
air filter.

Vacuum clean : A few passes of a vacuum cleaner can remove accumulated dust
and dirt

Oil-free compressor air : Point the compressed air nozzle in the opposite direction
of the filter’s operating airflow (blow from the filter’s exhaust side toward the intake
side)

Cold water rinse : Collected dirt is washed away using a standard hose nozzle with
plain water, make sure the filter is completely dry before returning to service

Immersion in warm soapy water : Dip the filter in a solution of warm water and
mild detergent and rinse the filter in clear water and let stand until completely dry
before returning to service.
4.7.1 Storing the Filter
The ideal storage condition for the air filter is a cool, dry, dark environment. High
temperature, humidity, and ultraviolet light adversely affect the filter media (foam). Foam
also degrades when exposed to solvents and sulfates, such as engine exhaust.
Controlling relative humidity between 40%-80% and temperature between 4.4°C to 32.2°C
(40°F to 90°F) yields an acceptable environment. Covering the filters with dark plastic
keeps the foam dry and protects it from ultraviolet light. Purchase enough to keep adequate
inventory for no more than a few months, filters could degrade under long term storage
conditions.
Before returning a filter to service, visually inspect it for tears or rips that may have
occurred during cleaning. Do not reinstall a torn filter as it will be ineffective in
trapping particulates and will interrupt air flow distribution. You may order
replacement fan filters (part number RAF1440) by contacting your SMART EC sales
representative.
