Installation
PTO SELECTION FOR
TRANSMISSION
Blower speed and pressure require adequate
horsepower and torque. See Performance Curves
on page 14.
Engine speed and blower speed require the
adequate ratio PTO be installed for proper blower
operation.
ENGINE SPEED
Keep engine speed constant when the blower is
in the operating cycle. Install a constant‑speed
governor or throttle control system to ensure
proper blower operation.
PRESSURE RELIEF VALVE
Size the pressure relief valve for the correct air ow
and pressure rating. Install the valve as close to
the blower as possible and before the check valve.
Ensure that pipe compound is used on the threads
of the male end of the relief valve to seal against
air leakage.
An undersized or improperly set relief valve
will cause the blower to operate at higher
temperatures. This can cause the blower to
overheat, causing irreparable damage.
AIR FILTER
Select a lter suitable for the air ow requirement
of the application. Use air lters on food and plastic
products to prevent contamination.

to operate at higher temperatures. This can
cause blower to overheat, causing irreparable
damage.
SUCTION AND DISCHARGE PIPING
All piping should be free and clear of any welding
slag or foreign material.
The suction piping requirement is a minimum
of 5 in. (127 mm) diameter for proper ow to
the blower.
Discharge piping is a minimum of 4 in.
(102 mm) diameter.
Do not use a rubber elbow in the suction line
during vacuum operation. The elbow will fail
causing the blower to overheat. This will cause
damage to the blower.
MOUNTING BRACKET
To reduce stress on the blower housing, be sure to
properly mount the blower with the correct bracket.
