W-70700 WASP Primary Fuel Filter
|
Flow rates range from 1 - 20,000 lit/hr 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.

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.

Flow rates are approximate
ss = stainless steel gs = galvanised steel F = flanged connections
Aluminium filter body and cover- maximum working pressure 4 bar - maximum operating temperature 90°C Options:
- Models 70501 & 70700 can be fitted with a 300W 230V heater (settings 35°C or 70°C)
- Models 70107 & 70501/3 can be fitted with a magnetic column to remove ferrous particles.
Installation
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).
Servicing
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. Replace elements and seals as required, see Add-on tab.
