SINGLE-STAGE VACUUM GENERATOR
INSTALLATION & OPERATION INSTRUCTIONS
GENERAL INFORMATION
m
DANGER
Do not pump flammable or ex-
plosive gases or operate in an atmosphere
containing them.
Ambient temperature for normal operation should not
exceed 125˚F (52˚C). Low atmospheric pressure at high
altitudes reduces performance of this unit.
Materials used in construction of the single stage vacuum
generator include anodized aluminum and brass. If unit
will ingest substances other than air, consult local Gast
representative for material compatibility.
INSTALLATION
m
CAUTION
Supply pressure regulated air to inlet
of vacuum generator. Excess pres-
sure can cause parts to burst.
1. This Gast vacuum generator may be mounted in any
position. Mounting holes are provided in aluminum
body. Shock mounting is not required. Remove
plugs from the IN and OUT ports
2. Connect a supply of clean, dry, regulated air to inlet
port in aluminum head. Regulator setting should be
between 30 and 70 psig (2-5 bar). Best setting is 68
psig (4,7bar). NO LUBRICATION should be used
with Gast vacuum generators.

occur if hazard is ignored.
WARNING
PLEASE READ THIS MANUAL COMPLETELY BEFORE USING
THIS PRODUCT. SAVE THIS MANUAL FOR FUTURE REFERENCE
AND KEEP IN THE VICINITY OF THE PRODUCT.
3. Vacuum connections to system must be equal or larger
than port. Smaller piping will cause lower vacuum flows.
Sealant should be used on all threads to prevent
leakage. Be sure to keep excess sealant from being
drawn into vacuum generator. Dusty or dirty applications
should have a filter installed to prevent material from
being drawn into generator.
m
WARNING
Do not restrict exhaust air. This can
cause vacuum port to become pres-
surized causing components to burst,
resulting in injury or death.
4. Muffler supplied should be attached to exhaust port.
NOTE: Restricting outlet of this muffler, will reduce both
flow and maximum vacuum.
OPERATION
m
WARNING
Keep away from air stream. Solid or
liquid material exiting the exhaust
port can cause eye or skin damage.
To operate the vacuum generator, turn on the regulated air
supply. Air flowing through unit causes vacuum to develop at
intake ports. Material can enter vacuum generator either in
compressed air stream or at vacuum port, it will be ejected
through exhaust muffler.
After adjusting regulator and supplying inlet air, block off
vacuum line to check for maximum vacuum. Reduced
vacuum may be the result of system leaks. If this condition
appears, check and seal leaks.
SERVICING
This Gast vacuum generator requires no scheduled
maintenance. If performance drops, it may require cleaning.
In most cases it is not necessary to remove vacuum
generator from system.
m
WARNING
Disconnect air supply and vent all air
lines before servicing. Parts may
burst if air is on when unit is
disassembled.
1. Turn off or disconnect air supply.
2. Remove and clean muffler.
3. Remove and wash all parts in mild detergent and warm
water to clean.
4. Reassemble in reverse order.
