Integrity Series Filter

The Integrity Series Filter builds on Refuel’s reputation as the leader in closed–loop filtration systems, for long–term stored fuel applications. The Integrity Series Filter delivers industry leading filtration technology, removing particulate from stored fuel down to 0.5μ (microns) and features a water holding capacity of 3L per filter. The result is pristine reliable fuel for emergency generators, ensuring clean start–up and continuous operation.

The Integrity Series Filter uses a patented* covalent bonding process and features self monitoring technology that automatically triggers a system warning when the filter enters the final stages of its effective life. The patented chemistry of the new Integrity Series Filter works by forming a covalent bond with the hydrogen atom of any water molecules present in stored diesel. Covalent bonding is a form of chemical bonding characterized by the sharing of pairs of electrons between atoms, and other covalent bonds. This chemical reaction allows the filter resin to absorb water whether it’s free standing, emulsified or water separated alcohol found within fuel.

The covalent bonding technology creates the self-monitoring properties of the filter. As the filter removes water and reaches its capacity it automatically slows the fuel flow rate through the filter, triggering a system pressure change and alerting the operator of the need to replace the filter element. This ensures the filters are not used beyond their effective specification, allowing maximum protection for mission critical emergency. 

* Refuel’s new Integrity Series Filter technology has been granted patents in Canada, The United States and over 20 other countries.
