This is a used filter tank ( base only ). It suits Filtrite/Quipmaster series 2000 and 3200 D.E. filters and also the cartridge filter that used the same tank. If you still have one, it may not be grey like this one. It may be dark blue or brown. Grey was the last colour they used before the company disappeared many years ago. Its in excellent condition. I dont know if you can get these new anymore, but if you can, you will be paying big dollars.... So save yourself big dollars. Measurements are width = 335mm x height = 335mm, weight is approx. 3kg. It has 2 x 40mm union nuts at the bottom which are inlet and outlet ports, these connect via pipework to your backwash valve. Local pick up OK ( Wyong NSW ) or I will post at cost which will be determined at end of auction. Please dont ask me postage costs, I have very limited time with work commitments, (two jobs).You can visit the Aust. Post web site and work it out with measurements provided.....Thanks.
