Pneumatic Actuation

Operation: Logan Clutches require a 2-position valve to function properly, (if the solenoid is not activated, air will not pass through the valve). A pressure switch must be installed in the inlet line to ensure that a minimum of 90 psi (6.2 bar) is available prior to clutch engagement. A 20-micron filter element should also be installed before the switch to minimize excessive dirt, oil and moisture.

If an air source is not readily available on your equipment, Logan suggests using an air compressor capable of producing
0.14 SCFM at 100 psi (6.8 bar).


Hydraulic Power-Pack Unit with SOFTSTART™ Feature

For vehicles that are not equipped with an air or fluid source, Logan offer a hydraulic D.C. motor power pack. Units run when clutch is engaged and shut off when full actuation pressure is reached. Units are preset to re-energize when fluid pressure falls to a minimum pressure and relieve (through a pressure relief valve) when pressure exceeds a maximum clutch pressure. A local and remote provision for actuation is supplied. Operated by a 12 VDC or 24 VDC power supply, the power pack should be mounted away from the engine exhaust manifold, dirt and heat.
