The pneumatic lubricator provides a simple solution for effect lubrication of actuators linked to a circuit. When compressed air flows towards the lubricator, it comes across a flexible diaphragm resulting in partially air blockage which creates a small pressure difference between the inlet and outlet air. Due to existing high pressure, the oil from bowl is pumped towards the regulation pin through a tube with a filter. the transparent dome provides visual access of the drops with accurate metering. The plug next to the dome is unscrewed to ensure filling of oil in absence of pressure. The front and back of the unit features a port (1/8 for size 1 and 1/4 for size 2) which ccan be used in combination with pressure gauges, pressure switches or
as an additional air intake.
