The EL-O-Matic breather block provides corrosion protection of the actuator spring chamber. It should be used on applications where the actuator is located in a corrosive atmosphere which would otherwise be sucked into the actuator through the “B“ port during the spring stroke. The breather block has an built-in quick exhaust function to improve the spring stroke time (see table in data sheet). An optional speed control can be provided to regulate this closing time.
