Overview

1.4. Air Requirements

The quality of the air that you supply to the stage is important to the operation of the stage. Aerotech
recommends that you connect the air supply to the air inlet with a polyurethane air hose.

(2) The filtration requirement is to prevent particles from clogging the air bearing openings.
(3) Aerotech recommends using a polyurethane air hose.
Aerotech also recommends that you install a pressure switch (P/N: MCA03094) tied to the motion
controller's emergency stop (ESTOP) that will remove power to the air bearing if pressure drops below 40 psi
(a drop in pressure could result in contact between bearing surfaces which could cause damage to the
surfaces). For easier air-supply setup, you can purchase pneumatic kits and filter/filter-dryer kits from
Aerotech. Aerotech's ABF Air Filtration Unit incorporates air filtration plus a pressure monitoring switch.
The pneumatic counterbalance pressure supply is determined by the amount of payload carried by the stage
