What is the difference between ADH4000 series heavy-duty auto drains and AD402(-A) auto drains?
-
ADH4000 series heavy-duty auto drains are mainly used by connecting them to equipment that generates a large amount of drainage such as compressors, air tanks, aftercoolers, and large refrigerated air dryers used upstream of the main line filter.
The max. operating pressure is 1.6 MPa, and the product can be used in up to medium pressure lines.
The piping port is facing horizontally and is for connecting to the end of a pipe.
As this is a heavy-duty auto drain, in order to reduce malfunctions caused by foreign matter entering from the compressor or piping, the actuation mechanism is located at the top of the product, and the drain does not directly come into contact with the actuation mechanism.
AD402(-A) series auto drains are used mainly to treat drainage from small compressors, air tanks, aftercoolers, and refrigerated air dryers.
The max. operating pressure is 1.0 MPa. The product is also suitable for use on the downstream side of a pneumatic line.
The piping port is facing upward because it is for connecting to the end of downstream piping branched from the main pneumatic piping.
An element is provided at the bottom of the port so that the drain does not directly come into contact with the actuation mechanism and foreign matter does not flow into the product.
There is a N.O. and a N.C. type AD402-A series auto drain. Select according to the size of the compressor and the desired application.
