PHASE (DRY TYPE) AIR CLEANER
The multi
-
phase (or tri
-
phase) air cleaner is a dry type filter for heavy duty applications
extra protection against dirt and dust. On this type, after air is drawn in through the rain cap, it
spins in circular motion around the outside of the dry type element.
This circular motion causes the
heavier particles to be centrifuged or thrown outward
the outer shell of the cleaner. The heavy
particles then fall to the bottom of the shell and are eventually expelled through the automatic dust
unloader. The normal vacuum within the air cleaner holds the lips of the unloader closed until the
weight of the accumulated particles builds up sufficiently to overcome that of the vacuum and the lips
open briefly to
"dump" the accumulation. Air cleaned by centrifugal action is then drawn through the
dry type element and into the carburetor. The dry type element on the multi
-
phase air cleaner is
serviceable
--
it can
be
cleaned in water and soap (see following instructions) up to 10 times before
replacement is required.
Service multi
-
phase cleaner at the intervals stated in the following steps
--
perform services
more often under severe conditions or if power loss is noted.
1. Check condition of screen on rain cap daily
--
keep screen clean and free of debris at all
times.
2.
After every
25
hours of operation, disconnect retainer bar and remove element. Clean
inside of filter body. Compressed air can be used to clean out this element if air pressur
is less than 100 PSI.
(A)
Insert air nozzle inside element and blow dust out.
(B)
Hold nozzle at least
6
inches away from element to clean dust from outside surface.
(C)
If compressed air is not available, gently tap element against palm of hand
--
do not
tap against hard surface.
