Industrial filter for a variety of liquids

摘要

The filter unit has a filter box, essentially rectangular, with side walls, and an opening looking down, a filter assembly within the box, and a further sealed, liquid tight box - a tank, joined below the filter box, of similar construction, and having a maximum high fluid level. Both boxes should be liquid tight up to the maximum level, and where there are elements connected from wall to wall their fixtures on the wall must be liquid tight, at least below the minimum liquid level. To simplify construction, wherever possible, the walls of the tank, and/or the box, are one piece, and may serve one or both respectively.
