Caution:
Incorrect equipment will cause blower failure. If you are not using
a Paragon kit, the following accessories should be installed:
Power Take Off For Transmission
• Horsepower and torque rating must be adequate for blower
RPM and pressure.
• Select ratio for required engine speed and correct blower
shaft speed.
Constant Engine Speed
• The selected engine speed must remain constant throughout
the blower discharge cycle. This requires ECM programming
or a trouble control system.
• Program ECM for max 100 RPM “ramp rate” per second.
Relief Valve
• Sized for correct CFM and blower pressure rating.
• Installed on delivery side before check valve.
• Use pipe compound on male pipe thread of relief valve.
• DO NOT
use thread tape.
Air Filter
• Sized for correct CFM to suit application.
Caution:
An undersized filter will cause immediate
overheating of blower. The filter should not exceed 17” water
restriction. Do not mount air inlet of the filter close to truck
exhaust. This will increase the blower operating temperatures
above the maximum limits.
Suction Delivery and Pipework
• Should be free of weld beads and foreign metal.
• During vacuum applications,
NEVER
use rubber elbows
without internal support.
Rubber elbows will collapse
under vacuum, restricting the airflow to the P858/P1057,
and causing the P858/P1057 to overheat.
Mounting Bracket
• Strong enough to support blower weight and torque
• Allow a minimum of 1/2" clearance between the blower and
frame rail (or other non-moveable object) to prevent damage
to the blower.
Check Valve
• Sized for maximum CFM with minimal restriction.
• Should have at least (1) check valve mounted on the trailer at
the hot air hose connection.
• Must be inspected periodically for damage.
Mufflers
• Sized for maximum CFM with minimal restriction.
• Mounted downstream of the relief valve.
• Stainless steel is required for sensitive product applications
Vacuum Relief Valve (Tractor Mounted)
• Sized for correct CFM ( Not to exceed 15” of Hg ).
• This valve needs to be installed between the P858/P1057
Blower filter and the P858/P1057 inlet.
• Must be fitted with a separate filter element to prevent Blower
damage when it opens.
Note:
When vacuum loading it is important that a vacuum relief
valve is installed within the system.

• Blower shaft to be parallel with first shaft to within 1
degree.
Mounting Plane
• Blower can mount in two planes for horizontal and
vertical airflow.
Note:
1. Pre-cleaners are not recommended.
2. Use only packing-free stainless steel mufflers
for contamination sensitive products.
PTO Drive Shaft Single Piece
• Blower shaft must be parallel with the PTO
shaft axis /- 1 degree to minimize
vibration.
• Use tubular, balanced drive shaft.
• Do not force end yokes into Blower or PTO
shaft.
• Blower shaft is 1-5/8” dia. with 3/8” key.
• Maximum driveline working angle - see table
below:
PTO Drive Shaft Two Piece
• Consult local driveline specialist prior to operation
