Air trap is useful device to evacuate condensate from air or gases line. It has two types flanged and screwed. Working attributes are: size varies from DN15 to DN25  or 1/2” to 1” and PN16 nominal pressure, 125 working class, 220°C or 428 ˚F maximum working temperature. This air trap is produced base on DIN or ANSI standards.

Air trap Type AT12

  • In air and compressed gasses system, humidity of air and gases is usually converted to condensate and flocked in the system. This condensate causes to inappropriate operation, equipment corrosion and system damage too, so it should be evacuated immediately and it is air trap function. AT12-01 air trap can be serviced or maintained easily without any separation from pipeline. According to the measure of condensate. Floater ball which there is in air trap, is floated and moves the connected lever and this lever changes the position of small shot .it gradually open or close the orifice and transient alteration does not effect on it. This kind of trap is used in gases, compressed air line to evacuating variable measure of condensate.

  • Floater air trap is installed vertically in pipe line or under the tanks and its floater and lever stand horizontally .In fact it stand in a position which its floater goes up and down vertically and arrow on plug shows downward. A bypass system can be considered for emergency or servicing time. In following fig., correct installation are shown.
