WASP W-15 Range

A newly designed primary fuel filter/water separator providing protection from damaging water and particulate commonly found in diesel fuel.

WASP W15 fuel filter/water separator Description

The new 4 port high performance WASP W-15ST series is compact and simple to install.

Fuel flow is up to 150 litres per hour together with a water separation efficiency greater than 98% and a pressure drop of only 20 mbar offering minimal restriction to fuel flow.

Either transparent or metal bowl options are available and all models are fitted with a washable stainless steel element which means no replacement elements.

Installation is before the fuel lift pump ensuring full system protection with two port sizes available,  ½'' x 20 UNF/SAE & M14 x 1.5.

The WASP W-15ST series has three stages of operation

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 stainless steel filter element. This removes all particulate above 100 micron still suspended in the fuel after the separation process.

Features

  • Aluminium die-cast filter head/ bracket for easy installation.
  • Transparent (Trogamid® T5000) or aluminium bowl options.
  • Pleated stainless steel washable element, surface area 50 cm2.
  • Thumb screw plug to drain water and impurities from bowl.
  • Ball valve to drain water and impurities from bowl (optional on transparent bowl models only).

Installation

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

Maintenance

  • 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
