3.0 Equipment Adjustments
3.1 Suction System Media Flow Adjustment
The ProFormer
™
suction blast system is equipped with the SAR-2 media regulator to
control the flow of media to the suction blast gun. The regulator is located at the
bottom of the storage hopper assembly inside the left component access door.
The amount of media entering the hose is controlled by how far the media hose is
inserted into the regulator. For normal operation, approximately ½ of the air inlet port
is blocked by the media hose. This may vary slightly when changing media size nozzle
size, and/or blast pressure.
To find a uniform media flow, loosen the thumbscrew and slide the media hose into
the SAR-2 regulator to increase and withdraw the hose to decrease media flow at the
nozzle. To determine if media is flowing, look through the media regulator air inlet
while the gun is operating. Listen for the sound of the blast to be smooth and
constant.
3.2 Pressure System Media Flow Adjustment
The ProFormer
™
pressure blast system is supplied with the patented Sure-Flo
®
Media
Regulator which is installed at the bottom discharge port of the pressure vessel. By
rotating the T-handle, media flow through the regulator and out of the blast nozzle
may be adjusted.
Step 1:
Rotate the T-handle counter-clockwise until there is no resistance. Reverse
direction and make three full turns of the handle.
Step 2:
As the T-handle is turned clockwise, the media flow through the regulator will
be reduced. While the system is blasting, make final adjustments in ½ turn, ¼ turn,
or 1/8 turn increments.
IMPORTANT
Optimum and most efficient blast is when the media exiting the blast nozzle is
just visible. Sure-Flo
®
Media Regulator adjustment may vary slightly when
media size, nozzle size, and/or blast pressure is changed. There are occasions
when blast pressure, media, and nozzle size requirements will not allow the Sure-
Flo
®
Media Regulator to be properly adjusted to the desired media flow rate.
Refer to the tag attached to the regulator T-handle for additional instructions
