Description

BWT PSJ100 Prefilter System 4.5" × 10"

The BWT PSJ100 is a high-capacity commercial prefilter system designed for installation before reverse osmosis equipment or as a standalone filtration system.

Its included BWT FB5W Fibron cartridge provides dual-purpose sediment and carbon filtration, reducing dirt, rust, sediment, chlorine and unwanted tastes and odours from the incoming water supply.

Removing chlorine and sediment before the water reaches a reverse osmosis system helps protect the membrane from degradation, blockages and premature failure.

The PSJ100 features a downstream pressure gauge for monitoring water pressure and identifying when the cartridge is becoming restricted. An integrated vent button allows trapped air and pressure to be released during cartridge replacement.

A mounting bracket and housing sump spanner are included for convenient installation and servicing.

  Coffee Parts Thoughts:
  
  The PSJ100 is an important first stage when installing a BWT bestaqua reverse osmosis system. Its FB5W cartridge removes sediment and chlorine before they reach the RO membrane, helping maintain water flow and extend membrane life.
  The downstream pressure gauge makes maintenance easier by showing when the cartridge is becoming restricted. Cartridge life will vary according to incoming water quality and usage, so it should be replaced earlier if pressure or flow begins to drop.
