WASP Spin-On Range

The WASP spin on filter range is a cost effective method of extracting contaminate from fuel. 


The filters range from a rated flow of 11 litres per minute upwards and can be supplied with paper filters for staining or glass filters for emulsified water removal. For fine cleaning, the range also offers a 3 micron straining filter and head with a high flow rate.

In heavy-duty filtration, the efficiency of the filter is the key to protecting the engine. Analysis of fuel from heavy-duty diesel engines has shown that about 90% of the particles that can harm an engine have a size between 5 and 15 Micron.

Unequalled by any traditional filter media, WASP spin on filters performs at least twice as efficiently as cellulose and delivers almost 100% filtration efficiency for this range of particles. While other filter medias are made of cellulose or glass fibres, the WASP emulsified water removal system is a composite of bonded layers of synthetic filter media.


High Flow Range
