Operation Manual
Mensor Model 73
Shop Air Booster System
GENERAL INFORMATION
The Mensor Model 73 Shop Air Pressure Booster generates 325 psi to 750 psi using a 70 psi
to 150 psi clean dry shop air source. The Model 73 consists of a single 5 to 1 pressure boost
stage with limits for speed control and maximum output pressure control. To achieve the 325
psi output, a minimum supply of approximately 70 psi is required. To achieve 750 psi, a 150
psi supply is required. 150 psi is the maximum input pressure the unit should be subjected to.
The unit is purely a mechanical device and has no electrical requirements.
WARNINGS AND SAFETY PRECAUTIONS
Caution:
High Pressure Gas can be extremely dangerous if improperly
handled.
Caution:
Unit should be operated, adjusted and maintained by qualified
personnel trained in high pressure pneumatics.
Caution:
All Tubing, Fittings and connected devices must have a working
pressure rating equal to or greater than the maximum required
pressure.
Caution:
All connections should be in good mechanical condition, i.e. good
threads on fittings, tubing free of kinks or nicks, etc.
Caution:
All connections should be properly installed and tightened.
Caution:
Small articles exposed to the escaping gas can be propelled at
ballistic speeds to the endangerment of nearby personnel and
equipment.
Caution:
Under certain conditions the noise level created by gas exiting
equipment under high pressure can become dangerously high.
Caution:
The maximum input pressure to the unit is 150 psi gauge pressure.
The input regulator and the input filter are rated for 150 psi
maximum.
INITIAL SETUP AND CHECKOUT
On initial setup, user should check to insure no shipping damage has occurred to the unit or
the container it was shipped in. Prior to connecting pressure, check all hoses for kinks and
nicks and insure fittings are snug. Verify that the regulator filters are not contaminated with
