  • Custom Measured – CNC profile frame providing strength and durability
  • Minimal Head and hydraulic Loss
  • Fail Safe Overflow – eliminates flooding when the unit is full
  • Ease of installation/removal – All units are bolted into the cesspits at 2 points allowing ease of removal if required
  • Filter Bags – fabricated  with a 200 micron filter mesh with an internal oyster mesh bag for protection. Handles on the bag allow for ease of removal for cleaning purposes

The PC Environmental Filter is made from durable, non-corrosive materials including:

  • Aluminium
  • Stainless Steel fastenings
  • Silicon sealant
  • 200 micron filter mesh and oyster mesh liners


Filter Frame:

The aluminium filter frame CNC formed to enhance material strength.

The Aluminium filter frame is laser cut for accuracy and a quality finish then CNC formed to enhance the materials strength and rigidity.
