Swimming pool/pool sand filter polyester BREGENZ II d520

The polyester filter BREGENZ II d520 in graphite gray (RAL7024), d400 is supplied with transparent filter cover and original Praher 1½" 6-way valve, side mount and valve piping.

The filter body of the BREGENZ II filter series, made of isopthal resin, resistant glass fibers and UV-resistant gelcoat, significantly facilitates maintenance and inspection, thanks to its special design. Carefully selected raw materials guarantee the highest mechanical resistance to the constant working stresses such as pressure fluctuations, switching on/off of the pump, closing/opening of the valve, etc. All components in contact with water are corrosion resistant, inhibit bacterial growth and have no negative effect on water quality.
