Home » Stainless Steel Filter Housings
The dome top bag filter housing is a new type of high-efficiency liquid filtration equipment designed in accordance with the principles of steel pressure vessels. It is manufactured from high-quality pure stainless steel and produced under strict quality standards with precision workmanship. Featuring a top-entry structure and a distinctive turtle-back cover design, the filter has a compact structure, optimized load distribution, excellent sealing performance, and enhanced operational safety, while allowing convenient filter bag installation and replacement. The stainless steel construction provides excellent corrosion resistance and long service life, making it suitable for a wide range of industrial liquid filtration applications. With reliable performance, fine workmanship, and flexible filtration configurations, it is widely used for liquid filtration and solid-liquid separation in industries such as chemicals, food and beverages, pharmaceuticals, water treatment, coatings, inks, and new energy.
Description
Optimal Structural Design to Meet All Filtration Requirements
- Top-tier Single Bag Filter: Currently the best single-bag filter, used with filter bags to satisfy all rigorous requirements.
- Side-Inlet & Top-Entry Design: Features a side inlet with top entry into the filter bag. This design automatically distributes pressure, prevents turbulence, reduces pressure loss, and effectively protects the filter bag.
- Top-Entry Direct Flow: Liquid enters the filter bag directly from the top, minimizing the volume of unfiltered liquid left inside the housing. The top cover compresses the filter bag across its entire surface, delivering exceptional sealing performance.
- Customizable Surface Finish: The inner and outer surfaces of the filter can be mirror-polished or sandblasted to suit various site requirements.
