These filters have many useful features:
• Self-priming (for a quick and easy start),
• Safety hose adapter (tap unit with 2 hose connections) which for safety reasons, can only be released when the valves are closed,
• Prefilter (traps large particles of dirt which can be cleaned regularly, allowing the maintenance period between media cleaning to be extended),
• Filter baskets (individual filter baskets for biological and mechanical media, which can easily be removed, and contents cleaned using the ‘Easy Clean’ grid).

Also with this model, if the fine filter pad becomes blocked, the flow rate can be increased using the new Xtender control function.
By turning the Xtender control knob on the top of the canister, the water will be re-directed but the biological function will be maintained, allowing the cleaning of the filter to be postponed for a few days.
This is to be used in emergencies for when immediate filter maintenance cannot take place.

Other features included are:
• Large filter baskets,
• High quality wear-free ceramic axle and bearings (which guarantee extremely smooth running),
• Large-area safety locking clips (for a tight and secure connection between the pump head and filter container)
