4.4.5 Factory Air
The factory compressed air supply must be “clean, dry and unlubricated” air with a
regulated maximum pressure of 100 psig (690 kPa). Depending on your application, the
actuator requires between 70 to 80 psi. Use a lockout device on the air line if required.
4.4.5.1 Pneumatic Connections to Actuator
Air connection to the Ultraweld L20 Actuator is made to the air inlet connector on the rear
of the actuator with a quick-connect safety pneumatic coupling. Refer to Chapter 5:
Technical Specifications for a pneumatic schematic.
WARNING General Warning
Synthetic air compressor lubricants containing WD-40 or Silicone will
cause internal actuator damage and failure due to the solvents
contained within these types of lubricants.
