LUBRICATOR
1Pages

The pneumatic lubricator is the simplest way of efficiently lubricating the actuators linked to a circuit. As compressed air flows towards the lubricator, it encounters a flexible diaphragm which partially blocks the way, creating a small pressure difference between the inlet and outlet air. Being at the higher pressure, the oil in the bowl is pumped through a tube with a filter towards the regulation pin. The quantity of oil can be metered accurately since the drops can be viewed through the transparent dome. Filling with oil must take place in the absence of pressure, unscrewing the plug next to the dome. On the front and back there is a port (1/8” for size 1 and 1/4” for size 2) that can be used with pressure gauges, pressure switches or as an additional air intake. 1/8’’ 1/4’’ 3/8’’ 3/8” 1/2” 3/4” 1” Oil mist Manual filling from the top 15 13 1.5 1.3 217 188 1300 1700 2200 2300 3900 3900 46 60 78 81 138 138 1600 3000 3650 3650 6100 6100 57 106 129 129 216 216 From -10 to +50 From -10 to +50 185 180 171 480 453 449 437 Compressed air or other inert gases 60 130 Vertical Vertical 1/8”, front and rear, lubricated air 1/4”, front and rear, lubricated air 450 800 16 53 2 M4 screws 2 M5 screws No. No. ISO and UNI FD22 (Energol HPL; Spinesso; Mobil DTE; Tellus oil) Install the lubricator as close as possible to the point of use. Fill the lubricator bowl with oil before pressurizing the system. Do not use cleaning oils, brake fluid oils or solvents in general. For the best lubrication results, set the drip rate to one drop for 300-600 Nl.
