Airmatic Lubricator
General
The Airmatic lubricator is a simple economical unit with a broad range of output. It is designed to be
operated with shop air. The stroke setting is easily adjusted to suit a wide variety of industrial
centralized lubrication needs. The package can be supplied with either a 1, 4 or 12 liter reservoir.
Application
The Airmatic lubricator is for use with cyclic oil lubrication systems. The unit can be used with single
line resistance (SLR), positive displacement injector (PDI ) and progressive distribution systems.*
Operation
Airmatic® lubricator includes an air actuated, spring return piston pump with an adjustable output
between 2 to 10cc for each piston stroke at discharge pressures up to 500 psi. Oil output is related
to piston travel and cycles per unit time. Stroke movement is preset to a fixed discharge and supply
air pressure governs the output delivery pressure. When used with positive displacement injectors, a
built-in pressure relief device lets the PDI reset after discharge.
For extended service, incoming air must be dry. Always use a suitable FRL unit (filter/regulator/
lubricator) to control air to recommended operating range. Normally, the air-operated Airmatic is
used with a 3/2-way electrical solenoid valve (optional) to control and vent shop air from the pump air
inlet. The 4 and 12 liter models are available with optional 3/2-way valve and cycle controller.
To adjust lubricant delivery, loosen locknut on hex socket adjusting screw (see Figure 1 on right). Turn
delivery adjusting screw clockwise to reduse discharge – use graduated label as guide, set to desired
setting and tighten locknut (insert shows setting at 8cc). For PDI systems, maximum discharge of
10cc/stroke is recommended.
