We are supplying this cheapish compressor to one of our customers. They are a small bakery and need a back up air system to run our liquid handling machinary when the compressor they share with the factory next door is swiched off at night!We will plumb it in with a Non return valve and set the pressure slightly lower than the main compressor.My problem is this, the compressor in the link comes with a manual drain tap / plug (underneath) which must be opened every 24hrs to drain condensate from the tank.A steam trap is a better answer than a solenoid valve. Didn't even think of it. Some of the plastic stuff seems to be way better made than the steel stuff, but people do have pre-conceptions.There are solenoid operated valves controlled by electric timers and float operated valves that do not require power (similar to steam traps). Neither work in freezing conditions.Solenoid valves can be mounted anywhere and a tube run to the lowest drain point. Float valves must be located under the air tank and that is sometimes difficult. The second solution is either a pneumatic operated with spring return actuator, normally closed, small ball valve, y-type seatvalve or membrane valve. Operation via a solenoide valve and timer. (Manual operation in addition should be present for start up and control)Do NOT use a solenoid valve directly, as small particles and dirt inside the tank, plus water can clog and corrode the solenoide valve.
