Types of Quick Open Bag Filter Housing
FiltEdge can review quick-open bag filter housing selection against your application, with manufacturing support from SFFILTECH in China. Confirm equipment compatibility and operating requirements before ordering.
2-24 bags, flow rate up to 1000m³/h, suitable for large automobile painting production line, water treatment and other high flow scenarios.
Dead-angle-free design, polishing degree up to 0.4μm, can be used in food, beverage, pharmaceutical and other industries with high standards for cleanliness.
Steam or hot water heating, for resins, adhesives, etc. that are easy to solidify, the temperature is always the same to maintain the fluidity of the filter media.
Characteristics of Quick Open Bag Filter Housing
Our quick-open bag filter housings, carefully designed by our researchers, can not only provide you with “fast” and reduce your downtime costs, but also make maintenance safe and simple.
Built-in spring balancer can offset 90% of the weight of the top cover, even for large equipment, you can operate it with one hand.
Compulsory pressure relief protection device, only when the internal pressure is completely discharged, the locking device can be opened, eliminating high-pressure injection, to protect your personal safety.
The unique O-ring groove used ensures a 100% fit between the filter bag and the shell.
High-strength stainless steel perforated plate is bent and welded to provide strong and stable support for the filter bag and prolong its life.
The inlet and outlet design with various directions allows you to adapt to the complex installation space without additional cost to change the piping layout.
There are various surface treatments such as sandblasting, polishing, electroplating, etc., which can meet the aesthetic cleanliness and at the same time, it is also easy to clean and maintain hygiene.
The precision range of 1-2000μm is suitable for coarse filtration and fine filtration in many industries.
Following the international standard design, it is compatible with 1#,2#,3#,4# standard filter bags on the market, and the procurement of accessories is not restricted.
Application of Quick Open Bag Filter Housing
Our quick-open bag filter housings have a filtration precision of 1-2000μm, and can be widely used in food and beverage, fine chemical, pharmaceutical and other industries; for example, automobile spray paint filtration, edible oil filtration, and viscous resins; and because it can be expanded to a greater flow rate through the parallel mode, it is often used in the water treatment industry for low-viscosity and high solid content.
Certifications for Quick Open Bag Filter Housing

No. FiltEdge’s quick release bag filter housings are less expensive to maintain than bolted ones. This is because the bare double needs to be screwed frequently, and the threads are more likely to be worn out after being wrenched around for a long time. The opening and closing structure of our quick-open type uses high-strength stainless steel, which is very wear-resistant.
You can use the jacket-heated quick-opening bag filter housing to replace the filter bag early through the “fast” action of the quick-opening mode before the viscous liquid cools down. Compared with conventional filters, it is less likely to be clogged.
Of course. In addition to the standard SS304/SS316 material, you can also choose duplex steel, Hastelloy material. The coating can also be made of 2-3mm PTFE, which can cope with strong acids and alkalis through its excellent plastic properties.
Of course, FiltEdge’s quick-opening bag filter housings are made of the same alloy as the housings, and their coefficients of expansion are the same; in addition, the sliding parts are also coated with high-temperature-resistant industrial grease. In addition, the sliding parts will be coated with high temperature resistant industrial grease to ensure that in the alternating hot and cold environments, there will be no “biting” phenomenon due to the expansion of the metal, so that your filter can still be opened and closed freely.
