Activair Pneumatic Differential Engine
Same as Pneumatic Differential Engine with quicker, easier door speed adjustment knobs and solid-state proximity switches.
Most Vapor bus door actuators are delivered as baseplate assemblies. The baseplate combines the pneumatic engine, linkage, and door suspension into a single pre-assembled unit that mounts directly to the bus structure above the door opening. The baseplate assemblies incorporate a linkage that converts rotary motion from the actuator to linear motion of the linkage rod and back to rotary motion of the door shaft.
- Easy-to-use door speed adjustment knobs
- Cushioning onset knob to set precise door open speed - prevents slamming
- Requires air supply pressure between 90 and 120 psi
- Solid-state, non-contact proximity switches
- Optional mechanical lock
- Maximum velocity and minimum force in the mid-point of its range of motion
- Maximum force and minimum speed at the extremes of its motion
For front or rear door applications
Exceeds all North American requirements
