W-701 WASP Primary Fuel Filter

W-701 WASP Primary Fuel Filter

“WASP Fuel Filters offer a new cost effective range of primary filtration equipment for marine, heating, industrial and transport applications.”

The problems that can occur due to water and sediment in fuel are well known and WASP Filters offer a wide choice of options to cover most requirements. All metal bowl units meet and exceed the requirements of ISO 10088 Annex B.

Flow rates range from 1 – 20,000 liters per hour and port sizes are from 1/4” BSP to 2” BSP. A DN 50 flanged version is available on the 2” ported model. All models have a maximum working pressure of 4 bar.

These WASP strainers are fitted with a well constructed ‘washable’ stainless steel element that will give many years of effective service. Micron ratings available are 60, 100 and 300 with 400 micron offered on the 2” models.

Pre-cleaning liquids by passing it through a washable strainer will assist in reducing costs down stream. The only consumable item in the WASP Liquid Strainers is a seal kit.

  • Up to 20,000 litres per hour flow rate
  • 1/2'' to 1'' BSP connections
  • Inexpensive solution
  • Choice of separators, paper elements or long life stainless steel
  • LM6 grade aluminium filter heads with reversible stainless steel bracket & bolts
  • Powder coated aluminium filter heads for corrosion prevention & long service life
  • 60 & 300 micron stainless steel washable elements
  • 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 stainless steel filter element. This removes all particulate above 100 micron still suspended in the fuel after the separation process.

The flow direction is indicated by arrows and must be observed. The filters can be installed in any position, however, we recommend that filter units are mounted vertically with the cover uppermost. This will assist the separation and collection of any water and particulate into the bottom of the housing ready for drain off (water separation of diesel fuel will only take place at lower flow rates).


Due to the simple and effective construction very little maintenance is required other than draining off any impurities, and the periodic removal of the washable element for cleaning.

Cleaning the filter is carried out by unscrewing the central bolt and then unscrewing the bowl. Carefully wash the filtering element with clean diesel, gas-oil or gasoline. Remount the unit and check that the seals are integral and well placed. Paper elements should be replaced as they cannot be reused (see above spares). Water can be drained by opening the bleed screw on the lid and then the water drain at the bottom of the bowl.
