Condensation can also form in the air tank of your compressor. When this
happens, a mixture of air and moisture will be expelled through the service
valve and into whatever is connected to the valve (e.g. air hoses, metal air lines,
pneumatic tools, spray guns). An in-line filter or dryer, available from your
local Quincy distributor, may be required to eliminate the moisture.
Condensation in the air tank can be kept to a minimum by draining the tank
on a daily basis. This also reduces the risk of rust developing and weakening
the tank.
Manual Tank Drain Valve Operation
The manual tank drain valve on portable compressors
and some stationary compressors is located on the
underside of the air tank. Portable compressors can be
tilted in the direction of the drain to allow removal of
tank moisture.
Some tanks use an internal drain tube (Refer to Fig.
3-3, Internal Drain Tube ) to drain the moisture.
Tank pressure is required to force moisture out of the
tank through the drain tube. Safe removal of tank
moisture from the air tank is dependent upon an
internal tank pressure of 20 to 30 PSIG (no more than
30 PSIG). Higher internal tank pressures are danger-
ous and could cause serious injury!
Do not open a manual tank drain valve on any air tank containing
more than 30 PSIG of air pressure!
Never attempt to relieve an air tank by removing a pipe plug or any
other system component!
Manually Draining An Air Tank:
Step 1) Disconnect & lockout the compressor from the
power source (electric models) or disconnect the spark
plug wire from the spark plug (gas engine models).
Step 2) Tank(s) subjected to freezing temperatures
may contain ice. Store the compressor in a heated area
before attempting to drain moisture from the tank(s).
Reduce the air pressure in the tank to 30 p.s.i.g. by
pulling the pressure relief valve ring (refer to
Fig. 3-4,
Checking Pressure Relief Valves & Relieving
System Pressure
).
Step 3) Open the drain valve and allow the moisture
and air mixture to drain from the tank.
Step 4) Once the moisture has been completely drained,
close the drain valve.
