Product Details
Industrial bobbin wound filters with diameters from 1050 mm to 3000 mm, with the corresponding flange connections for different filtration velocities. Replaces the Atenas model. New top cover system with quick closing system 400 x 500 mm opening. The air relief valve is fitted into the cover in order to help eliminate air from the filter. 1½” collector arms injected in ABS at the necessary lengths for each of the filters and without joints. Lengths from 90 mm to 525 mm. A reduced head loss is achieved thanks to the greater diameter of the arms. The 90 mm diameter collector tubing is injected in PVC. Water purge and air relief are faster due to a 1" connection. The distance between the top sand layer and the diffusor head (“freeboard”) has been increased to ensure greater water distribution during filtration and to prevent sand entering into the laterals during the backwashing. In the case of filters with diameters of 2350 mm, 2500 mm and 3000 mm, the top cover is Ø 400 mm that screws into place and has a PRFV high resistance neck ring. The 200 mm, 225 mm and 250 mm connections are in PVC and the foot is plain, both of which are features very similar to the Oslo and Prague models.
