Liquid drainer for compressed-air and gas systems PN 16 For continuous draining of gas and compressed-air system, float traps with "Simplex" control units (i.e. without thermostatic air vent) are used. To ensure perfect drainage, the air traps can be fitted with a balance pipe which allows air in the trap body to escape so that is cannot obstruct the flow of condensate into the trap. A balance pipe is not necessary if the trap is installed directly below the drain line runs vertically. In this instance the pipe leading to the trap should be of sufficient size so that any air can escape by bubbling through the condensate. All air traps are equipped
with a plug allowing a balance line to be connected, and are fitted with
a float lifting lever to facilitate manual purging of the valve area.
UNA traps are fitted with a perbunan rubber valve ball to provide tight
closure; a stainless steel valve ball may be specified for highter temperatures
and pressures. In the case of very small condensate flowrates the tightness
of the valve closure should be considered. |
