Features Different From The Traditional Mechanical Type: This compressed air condensate automatic drain is significantly different from the traditional mechanical automatic drain, which is a continuous drip. Premium Material: The shell of this float drain valve is made of cast aluminum alloy with plastic powder coating on the surface, which is not easy to corrode and rust, and has a long service life. Excellent Performance: This is a fairly stable float drain with excellent performance and a low failure rate. The drain of the drain is large and not easy to be blocked; it is an excellent choice for the drain of the new generation of compressed air equipment. Good Reliability: The automatic drainer is extremely reliable, no electricity, no noise, no loss of compressed air, you can use it with confidence. How It Works: When the drain buoyancy is less than the float weight plus the compressed air pressure, the drain closes; it opens when the buoyancy increases to drain condensate. Specifications: Model: HAD20B Port Size: Inlet=Outlet=1/2BSP Maximum Pressure: 20bar Maximum Temperature: 100℃ Maximum Capacity: 400L/H Weight: 602g(approx.)
