Description

  • Size Range: C15 up to C100

The spring chambers are exposed to the surrounding environment in applications that use a fail-safe actuator. Every stroke generated by the force of the springs introduces air from the surroundings into the actuator’s inner parts. The springs and the interior of the spring chamber become prone to damage. This could cause the product to malfunction in the case of corrosive and abrasive working environments.

The Breather Block isolates the actuator’s internal parts from the corrosive/abrasive surroundings by allowing only dry and filtered instrument air to flow into the spring chamber during the
actuator’s spring stroke. The Breather Block’s exhaust port only allows air to flow out of the spring chamber and prevents outside air from flowing in.
