DESCRIPTION AND OPERATION
Numbers in parentheses refer to Fig. 1.
The dual dry element air cleaner is remote mounted on
the fender of the vehicle. The air cleaner prolongs
engine life by removing grit and dust from the air as it
enters the engine. Grit and dust, combined with engine
oil, forms a highly abrasive compound which can
destroy the engine in a comparatively short time.

A rubber vacuator valve (18) attached to the dust cup
(17) in a downward position ejects grit, dust, and water
while the engine is running. The vacuator valve
minimizes the need for daily servicing. Even though
the valve is normally under a slight vacuum when the
engine is running, pulsing of the vacuum opens and
closes the rubber valve, expelling dust and water as
they collect. The valve also unloads when the engine is
stopped, by opening and releasing any accumulated
dust or water.
