Reservoirs with Filter and Low Level Safety Switch use gravity to dispense liquid.  They are designed to serve as a central reservoir of an oiling system.  They allow visual observation of liquid level and clarity.  This lubricator features a filter and low level safety switch that can be used to actuate warning devices or shut off a machine when lubricant levels become too low.

The durable, shatterproof acrylic reservoir tolerates temperatures up to 160° F.  It features a self-closing filler cap, Buna-N seals, plated steel tie rods, and aluminum alloy top and bottom plates.  A 100 mesh aluminum filter prevents debris from entering the liquid stream.  The low level safety switch has a polypropylene float.  The approximate usable oil level to the switch actuation point is 13/64”.  The circuit is completed when the switch reaches the low level point.  The 18 GA wire leads are 10” long. There is a 1/2” NPSM connection for conduit. The outlet is 1/8” female NPT and there is a 5/8"-18 thread for remote mounting. The diameter of the reservoir is 4 1/4” and total height of the unit is 7 3/4”.

Additional shutoff and sight feed valves are needed for the regulation of liquid flow (see “Oil Flow Control Valves”).
