The Chicago Pneumatic PNL Zero Air Loss Drain is an electronically operated drain valve, specially designed to drain condensate from compressed air networks. The PNL monitors condensate build-up with liquid level sensors in order to reduce excessive evacuations, minimizing air waste. An integrated alarm is inbuilt so that if a blockage or fault in the diaphragm occurs, a flashing light and volt free contact are activated. Fully automatic monitoring and a self cleaning function reduces labor costs and maintenance.
