A drain discharge device for discharging effluent comprises a valve with a single outlet and a plurality of inlets that selectively connects the single outlet to one of inlets in turn. The inlets, each of which corresponds to an outlet of an effluent discharging device, such as an air compressor or an after cooler, are each sequentially connected to the single outlet in order to drain effluent. Due to the sequential connection of the drain points to the outlet, the drain discharge device operates irrespective of air pressure differences at the drain poin...
An effluent drain system for draining effluent from a plurality of devices receiving compressed air from an air compressor, comprising: said plurality of devices including at least first and second devices connected to receive said compressed air in series; said first device having a first air pressure drop; said second device having a second air pressure drop, whereby an air pressure at an outlet of said second device is equal to a supply air pressure at an inlet of said first device minus said first air pressure drop and minus said second air pressure ...
