All ACI pneumatic transducers have a fail safe model.
When the installation requires dampers to close quickly on a power failure, or any actuator to assume a fail safe position quickly, ACI has the answer. Look for the FS suffix on ACI pneumatic interfaces.
- These are not bleed type interfaces. They consume no air at setpoint and require no increase in the size of the compressor. The controlled, high capacity, three-way branch exhaust valve allows the branch line to drop to zero on a power failure.
- Anodized aluminum manifold with gauge port - gauge can be factory installed.
- Air handling capacity of 750 scim.
- Field selectable input ranges.
- 0 -15 psig output (plus feedback).
- Manual Override - allows operation checkout before putting in service.
- Not position sensitive, mounts at any angle, on snaptrack provided.
