How does it work?

1. Separation:  

The incoming flow of fuel oil changes velocity and direction, reducing the possibility of further reduction of any water droplets present through impact.   

2. Coalescence:  

This takes place on and just below the flow dispersion member allowing the separated water to descend to the bottom of the filter bowl.   

3. Filtration: 

The fuel finally passes through the filter element to remove particulate.

Installation

A full range of fittings is available for easy installation.

  • If necessary refit the two port plugs supplied with the filter. If they are not to be repositioned check they are correctly tightened.
  • Follow the flow direction according to the arrows on each of the four ports.
  • This range of filters should be installed on the suction side of the fuel supply system before the lift pump.

Servicing

  • Check regularly for separated water
  • Drain off any separated water or impurities regularly via the thumb screw drain plug or valve
  • Remove clean and re-fit the stainless steel element as necessary
  • Replace seals and paper elements as required, see above spares
