4.1.3 Pneumatic Requirements
The factory compressed air supply must be “clean (to a 5 micron level), dry and
unlubricated” air with a regulated maximum pressure of 100 psig (690 kPa). Depending
on your application, the actuator requires between 35 to 100 psi. Stands include an in-line
air filter. Actuators (alone) require a customer-provided air filter. A quick-disconnect fitting
is suggested. Use a lockout device on the air line if required.
Air Filter
Actuators (alone) require a customer-provided air filter which protects from particulate
matter of 5 microns or larger. If a stand is mounted in a position other than upright
(vertical), its air filter must be relocated and oriented so its bowl is the lowest point, and
the air flow across the air filter is horizontal. This may require some re-plumbing of the
existing equipment at the customer site. The air filter is held in place by two screws on a
bracket bolted to the actuator support, and by the factory-installed tubing.
Pneumatic Tubing and Connectors
Actuator assemblies are not externally plumbed from the factory, but provide conventional
1/4-inch OD pneumatic tubing connection at the air inlet. If making connections for an
actuator, or if re-plumbing your system for a new air filter location, you must use 1/4-inch
OD tubing and connectors rated above 100 psi (use Parker “Parflex” 1/4 OD x.040 wall,
type 1, grade E5, or equivalent), and appropriate connectors.
Pneumatic Connections to Actuator
Air connection to the actuator is made to the AIR INLET connector on the top rear of the
actuator, with plastic pneumatic tubing. For installations using actuator-alone assemblies,
you must provide an air filter assembly which will support to at least 100 psig and remove
particulate matter of 5 microns or larger.
