Air compressor with propane tanks need to test every year?

This depends on how much is air tank, 1 cubic 10 kg below is simple pressure vessels, inspection-free is not need for 7 years of experience, a year 1 cubic above 10 kg is in need of an annual inspection. As the compressed air compressor, first to send to air tank inside, the air will stay for some time, here will precipitate the impurities in the air moisture such as foreign body, so the temperature of the compressed air have been reduced, if the absence of freeze drying machine, will send more good quality air.

by air compressor to provide gas source, seems provide water pump, air tank is almost reservoir. Air storage tanks can be uniform according to set the air pressure within the scope of a certain pressure, cushion pressure fluctuations, thereby reducing the start times of air compressor, the other storage tanks still can rise to precipitate the effect of foreign bodies such as the impurity moisture in air. Air quality is better, so after a gas tank, air compressor output air, there is a buffer, out of the air supply can better keep at a set value, can get a constant pressure gas system, the very necessary for the use of modern factory.

provide zero without air, due to the frequent air compressor starts, can make the motor starting current is very big, about general starting current is about 5 times the normal working current, at this time of air compressor for the energy consumption is larger.
