Astral Vic Filter -
Astral Vic Filter.
Industrial bobbin wound filters with diameters from 1050mm to 3000mm, with the corresponding flange connections for different filtration velocities. Replaces the Atenas model.
The 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 90mm to 525mm.
A reduced head loss is achieved thanks to the greater diameter of the arms. The 90mm diam 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 difusor head (“freeboard”) has been increased to ensure improved water distribution during filtration and to avoid sand entering into the laterals during the backwashing.
In filters with diameters of 2350mm, 2500mm and 3000mm, the top cover is Ø 400mm, sealed with bolts for high resistance. Available for pressures up to 2.5 and 4 bars.
An interior vinylester coating is required if ozone is to be used.
