 Bermuda Filterforce Duo 3500 Filter Pump

The Bermuda Filterforce Duo pumps are built to last with an outlet, and also an inlet designed for attaching to a skimmer.

As with the Filterforce, the running costs on the Filterforce Duo are also very low, complete with a 3 year guarantee (excluding impellor & shaft).

An extremely durable range of powerful, specialist filter pumps. All 5 models are extremely low wattage starting with the great value Filterforce Duo 3500 all the way up to the 10000 liters per hour model.

  • The Filterforce range can handle solid particles up to 8mm in size.
  • All Filterforce models are continuously rated so can run 24 hours a day, 7 days a week and 365 days a year.
  • Whether for powering a biological filter, UV clarifier or creating a superb waterfall, the Filterforce Duo is the perfect choice.
