Forbes Marshall Liquid Drain Trap FMLDT

The Forbes Marshall Liquid Drain Trap is a condensate drain trap ideal for removing condensate from pressurized gas and compressed air systems. The trap body is pressure balanced with the system of the main media through the balancing connection on top of the trap body. This ensures the media (Compressed air or gas) is locked in the trap body.

  • Leak proof operation
  • Can be repaired online after proper separation
  • Robust and reliable
  • Discharges condensate as soon as it is formed.
  • Can handle large quantities of condensate.
  • Avoids corrosion of compressed air lines and consumers.

    Frequently Asked Questions

    What is a liquid drain trap?

    A liquid drain trap is designed to automatically remove condensate, moisture or other liquids from steam or air systems. It operates by separating the liquid from the air or steam, discharging it while preventing the loss of steam or gas.

    Where are liquid drain traps used?

    Liquid drain traps are commonly used in steam systems, air compressors, HVAC and refrigeration applications, to ensuring efficient operation and prevent equipment damage due to trapped liquids.
