BSR MEDIUM AIR COMPRESSOR
GENERAL INFORMATION
The BSR Medium Air Compressor is a basic, but very important, piece of equipment. Be certain
to understand this information before any adjustments are made on this machine.
After the BSR Medium Air Compressor is plugged into the electrical outlet it will run
continuously until the air pressure inside the holding tank reaches the preset pressure. When the
pressure switch notes the proper air pressure inside the holding tank, it will automatically turn off
the motor.
When the motor turns off, the excess pressurized air that is trapped between the compressor head
and the check valve needs to be released. This is done automatically, when the pressure switch
shuts off, via the needle valve, which is bolted to the side of it. The needle valve is pushed open
by a small lever mounted on the side of the pressure switch. The holding tank shouldn t empty
through the needle valve. The check valve prevents this from happening when the needle valve
is open; it allows air to go into, but not out of the holding tank. The needle valve lets air out of
the compressor head so that when the motor turns back on, there will not be any pressure on the
compressor head. This prevents the motor from spinning around. When the motor starts up
again then the small lever comes off of the needle valve, thus allowing pressure to develop in the
compressor head again. This pressure will go through the check valve and into the holding tank.
On the side of the holding tank is a pipefitting. On this fitting is a pressure gauge, safety valve,
and drain valve. The pressure gauge shows you how much pressure is inside the holding tank.
The safety valve has a small metal ring on it. If the pressure gauge shows too much pressure
inside the holding tank, then you will need to pull the metal ring on the safety valve to release the
air. Caution! An excess amount of pressure in the holding tank can cause an explosion!
NEVER REPLACE THE SAFETY VALVE WITH A PLUG! The drain valve is for draining
the holding tank and removing water from it. Water develops in the tank due to condensation.
For your compressor to function properly, the holding tank needs to be drained on a weekly
basis.
There is a pushbutton on the back of the compressor motor. This button resets the motor should
it overheat. Newer models don t have a reset button; they have auto-reset when the temperature
of the motor cools down to the appropriate level.
The air then goes from the compressor (or house supply) to the Filter, Regulator, Lubricator
(F.R.L.) and manifold assembly. The filter collects any water that is in the air and deposits it in
the first glass bowl. This should be drained routinely by means of the petcock on the bottom of
the bowl. The regulator then allows only a preset amount of air pressure into the manifold. The
lubricator automatically puts oil into the air to keep all valves and cylinders in good working
condition. The lubricator bowl should always be kept full with 10w non-detergent oil.
