F5/F6/F7/F8/F9 Pocket Bag Filter and Air Conditioner Pocket Filter
This mainly includes F5, F6, F7, and F8 medium-efficiency bag filters, which can be used for intermediate filtration in air conditioning systems.
The frame is primarily made of aluminum alloy or galvanized plate, with a thickness of 21mm or 25mm.
The filter material is melt-blown synthetic fiber, with a V-shaped bag structure.
The inner frame consists of galvanized inner strips and galvanized pressure bars.
The 'bag support grid' provides reinforcement to prevent the filter from collapsing or deforming in poor working conditions, and a good hot melt technology prevents excessive compression or leakage between bags.
