2162/2F56D reagent-free filtration unit

The reagent-free filtration unit with a manual valve removes dissolved iron, manganese and hydrogen sulfide from water, along with turbidity and color. A fiberglass housing with internal polyethylene lining, granular filter media, a supporting gravel layer, and a drainage-distribution system — the same layout as in the automatic versions.

Iron and manganese are oxidized directly on the media and precipitate as sediment, which is retained within the media bed; filtering capacity is restored by backwashing, without reagents. The difference from automatic models is in control: the operator starts and switches the backwash manually, so the unit does not depend on electric power, but requires scheduled maintenance. The frequency of backwashing is determined by the combined content of iron, manganese and hydrogen sulfide in the source water.

Design 2162/2F56D: 21×62″ housing, Runxin 2F56D valve. Weight 41.6 kg.

Configuration within the line: vessel size 2162 (21×62″) with control valve Runxin 2F56D. On the same vessel size 2162 (21×62″) the line also offers Runxin F56A. The same control valve Runxin 2F56D is fitted on 2472, 4272, 3072, 3672 and others.

On vessel size 2162 the closest alternatives to Runxin 2F56D are Runxin F56A (weight 42.62 kg instead of 41.6 kg).
