Function
1
General Air Regulator/Water
Separator
The general air regulator/water separator filters air, separates
water and controls air pressure to pneumatic tools.
2
Pneumatic Air Regulator/Water
Separator and Lubricator
The pneumatic regulator/water separator filters air, separates
water and controls air pressure to pneumatic tools. The lubri-
cator adds oil to the air supplied to pneumatic tools.
3
Propylene Regulator
The propylene regulator is a two stage regulator. The high-
pressure gage, the inlet side, shows the pressure from the
cylinder and is graduated from 0 to 400 psi. The low pressure
gage, the outlet side, shows the working pressure and is
graduated from 0 to 30 psi (3 – 5 psi is normal).
4
Oxygen Regulator
The oxygen regulator is a two stage regulator. The high pres-
sure gage, the inlet side, shows the pressure from the cylinder
and is from 0 to 4000 psi. The low pressure gage, the outlet
side, shows the working pressure and is graduated from 0 to
200 psi (20 – 40 psi is normal).
5
Argon Regulator
The argon regulator is designed with a low pressure flow me-
ter. The high pressure gage, the inlet side, shows the pressure
from the cylinder and is from 0-4000 psi. The low pressure
flow meter, the outlet side, shows the working pressure and
is graduated from 0 to 30 CFH (5 – 20 CFH is normal).
