Water absorption filter bags

Efficient water removal solution for oils and fuels. High performance at low cost. Water absorbing filter bags form a new type of specially formulated and highly effective water absorbing material, made of cellulose fibre. In its pure form, such an absorber can absorb water from oil up to 100 times its own dry weight. However, in its pure form such water absorber tends to be unstable. Once exposed, it quickly absorbs moisture from the open air. In order to stabilise the water absorber for commercial applications, we mix a certain percentage of polyester fibres in the water absorber to formulate our unique media, which is capable of absorbing and retaining water content up to 70 times its own dry weight.

In addition to standard sizes of water absorbing filter bags, we also offer custom made filter bags. Customers are encouraged to contact us with the specifications of the application. As usual we make custom water absorbing filters that are tailored to the application requirements of each individual customer.
