The Martinic QS 500 filter tank builds on the successful QS 400 model and offers greater filtration capacity thanks to the larger tank dimensions. The split polypropylene body, joined by a steel band, guarantees mechanical durability and tightness.
The side-mounted six-way Praher valve with 1 1/2 inch internal threads is connected via a union fitting and allows easy switching between filtration modes. The included handling pallet makes it easier to transport and install the heavier tank at its destination.
The filter media of silica sand with a grain size of 0.4–0.8 mm is included in the delivery, together with the internal connection and a pressure gauge. The tank is designed for larger-volume private pools as well as public facilities with a high daily filtration load.
