What Are FiltEdge Bag Housings?
Types of Bag Housings
FiltEdge is available in single bag, multi-bag, different opening and closing configurations and pressure ratings, etc. There are hundreds of styles. You can contact us and we will analyze and select the most suitable bag housings for you according to your working conditions.
Maximum flow rate up to 40m³/h, #1/#2/#3/#4 bags are available. Suitable for low flow or intermittent conditions, with excellent cost performance.
According to different flow requirements, can be adapted to 2-24 bags, the highest flow rate of up to 1000 + m³ / h. Especially suitable for high flow, low viscosity conditions.
The same two bag housings can be used to switch the liquid from the main filter to the backup filter when the filter bag needs to be replaced, realizing 24-hour non-stop operation.
Features of Bag Housings
The product technology of FiltEdge’s bag housing can solve the filtration problems of high pressure resistance, corrosion resistance, high flow rate and high precision for your filtration system, which can reduce the cost and increase the efficiency for you.
FiltEdge can customize the number of bags according to the flow rate of your working condition.
Spraying and sanding, electrolytic polishing, pickling and passivation and other processes to solve the problems of aesthetics, hygiene and corrosion resistance of your production line.
ANSI/ASME flange, NPT/G thread, quick release chuck and other connection methods, 100% match your existing piping system.
The pressure is relieved before opening the cover, which guarantees the work safety for you.
Heavy-duty 304/316 stainless steel support basket reduces filter bag breakage and lowers your long-term consumable costs.
Our bag housings support bag compatibility, so you can look for the most cost-effective consumables when you replace the filter bag later.
The bag housings are routinely 0.6-1.0MPa, and can be customized with 2.5MPa high pressure models to cope with harsh working conditions.
Even if you are thousands of kilometers away from the project site, you can remotely control the progress of the project and complete the installation quickly and accurately.
Application of Bag Housings
FiltEdge’s bag housing systems can provide you with solutions for reverse osmosis (RO) membrane breakage, wastewater reuse, cooling circulating water; viscous fine chemicals such as paints, inks, resins, etc.; clarification and filtration of beer, beverages, edible oils, etc.; and high-precision filtration of cutting fluids, electrophoresis paints, etc. Our bag housings can be used consistently in these applications and provide excellent filtration.

The choice depends mainly on the impurity content of the liquid to be filtered and the flow rate. Generally speaking, for flow rates of less than 40 m³/h, single bag housings are more suitable. For high flow rates, e.g. 1000 m³/h, multi-bag housings are preferred.
Stainless steel bag housings are normally used, but the temperature resistance depends on the seal material, e.g. Viton/PTFE seals can reach temperatures up to 150 °C. Provide us with the chemical properties and temperature of the liquid you need to filter and we will help you to choose.
This is most likely due to a gas level being discharged from the bag housings tank or a water hammer effect during startup. You can install an exhaust valve to evacuate the gas before feeding the liquid. Also install a slow start valve in the front section of the filtration system to avoid the instantaneous shock of high pressure.
