DRAINMASTER®
Timed
Automatic Drain Valve
The DRAINMASTER is an automatic drain system designed to
eliminate the need to manually drain water and harmful sediments
from your compressed air system, thereby improving the systems
performance. The DRAINMASTER has a heavy duty motor for operation
under adverse conditions and an adjustable timer to meet specific
user requirements. By design the DRAINMASTER eliminates major
drawbacks of other compressed air draining systems. The valve
is brass for corrosion resistance and it is a full port ball
valve giving maximum and unobstructed flow with no clogging.
