Air and gas float traps FA31.1 (Carbon steel ; 1/2" to 1" - DN 15 to 25)

The FA31.1 is a series of fully automatic carbon steel eliminators specially designed for condensate drainage in compressed air and gas systems.

Typical applications include chillers, separators and main compressed air distribution lines.

  • Modulating discharge.
  • Unaffected by sudden or wide variations in load and pressure.
  • Direction of flow can be easily changed by repositioning the body relative to the mechanism and cover.
  • Metal to metal sealing.
  • Equalising (drain) and drain connections.
  • BDV - Bleed valve.
  • AFZ - Antifreeze device.
  • FLL - Float lifting lever

  • Compressed air and other non-corrosive gases compatible with the construction
