Johnson Controls A-4000-141 Oil Removal & Pressure Reducing Station

The Johnson Controls A-4000-141 is a filter/reducing station whose main purpose is to enhance the quality of air to be used in pneumatic control systems and also to control pressure. This minimizes interferences from air borne particles that might contaminate fragile pneumatic equipments and enhance general system efficiency. Primary pressure control maintains the output pressure while secondary pressure control maintains the input pressure and is suitable for use with various HVAC components including thermostats, dampers as well as actuators. Proper pressure management reduces system complexity and eliminates problems with its operation.
