About this product
The V121‑1 coalescer bag is a fluid filter element designed to remove water and fine particulates from fuel or hydraulic reservoirs. Woven from graded coalescing media, it captures micron‑sized droplets and solids, allowing clean fluid to pass through and improving system reliability. Supplied ready for drop‑in installation, it fits standard cartridge housings in aircraft service carts and maintenance systems.

PRODUCT DESCRIPTION

V121-1

  • Dual‑Layer Media: Inner coalescing layer agglomerates water droplets; outer depth layer captures solid particles.

  • Structural Support Core: Stainless‑steel mesh backing maintains shape under flow and pressure surges.

  • Easy Drop‑In Replacement: Cartridge‑style design fits common coalescer housings without modification.

  • Long Service Life: High media capacity extends the time between change-outs, reducing maintenance downtime.


  • Removes water and particulates during refueling operations.

  • Coalesces water from auxiliary fuel tanks in flight or on the ground.

  • Acts as a final barrier before fuel enters the engine feed lines.

  • Used in portable filter units for field servicing of APU and engines.


  • Will it remove dissolved water?

No, this bag removes free and emulsified water droplets. For dissolved water, use molecular‑sieve dryers.

  • How do I inspect for saturation?

Monitor the pressure gauge on the housing; a rising differential indicates water loading or clogging.

  • Can the bag media be reused?

No, once saturated with water or debris, replace the bag to maintain filtration effectiveness.
