What Is Polypropylene Bag Filter Housing?
FiltEdge’s Polypropylene Bag Filter Housing, also known as PP bag filter housing, is a material classification of plastic filter housing. Our Polypropylene Bag Filter Housing is mainly a single bag type, which can accept a maximum flow rate of 45m³/h. It is suitable for small flow rate and low pressure. It is suitable for small flow rate, low pressure and normal temperature working condition, such as electroplating, water treatment, chemical industry, semiconductor, food and so on.
Types of Polypropylene Bag Filter Housing
FiltEdge’s Polypropylene Bag Filter Housing adopts top-entry structure more, if your working condition needs, we can customize more matching pp filter housing for you.
Single Bag Filter HousingDepending on your flow rate, #1, #2, #3, and #4 bags can be installed to handle up to 175 GPM.
#2 Bag Filter HousingOne of the most commonly used filter sizes on the market, can handle over 95% of the conditions you encounter.
Size 1 Bag Filter HousingSize 1 Bag Filter Housing is the most commonly used filter size in the market, and can handle more than 95% of the conditions you encounter.
Features of Polypropylene Bag Filter Housing
Lightweight and chemically superior, the Polypropylene Bag Filter Housing is widely used in a variety of small flow rate applications. Not only does it make your maintenance more difficult, but it also reduces purchasing costs.
Both the housing and the filter basket are made of high quality PP, which will not precipitate metal ions during filtration.
The cylinder body adopts the whole injection molding process, no welding seams, balanced pressure and impact resistance.
Top-in-bottom-out, side-in-bottom-out and other structures optimize the flow channel to reasonably reduce the internal flow resistance and pressure loss.
Usually can be used in the process under 0.6-1.0MPa pressure.
Standard pressure gauge and air venting valve interface, easy for you to observe the internal pressure of Polypropylene Bag Filter Housing and judge whether it is clogged or not.
ANSI/DIN/JIS standard flanges, internal/external threads, and double union connections are available for you to connect with existing piping.
Seals are provided between the top cover and the cartridge, the filter bag and the support basket to prevent liquid bypass.
The #1, #2 Polypropylene Bag Filter Housing has a drain port device on the bottom to prevent acid and alkali solutions from spilling when changing the filter bag.
Advantages of Polypropylene Bag Filter Housing
PP bag filter housing has excellent resistance to acid, alkali and salt solutions, eliminating corrosion leakage caused by chemical reaction and downstream pollution.
Polypropylene Bag Filter Housing is about 60% lighter overall than stainless steel filter housing, making it easy for you to install and maintain.
Polypropylene material is not easy to scale, easy to clean; and compact size, easy to open the cover, convenient for you to change the bag alone.
PP bag filter housing is made of all-plastic material, unlike stainless steel/carbon steel filter housing which is easy to rust in humid environment, the service life is greatly extended.
Both the linking method and the filter basket size are designed in strict accordance with international standards, which is easy to link with your existing pipeline and reduces the cost of remodeling and purchasing.
Compared with metal filters, the initial purchase cost can be reduced by about 50%. And there is no welding problem, no metal corrosion, extended service life and lower cost of use.
Effective Filtration Area of Polypropylene Bag Filter Housing
FiltEdge’s Polypropylene Bag Filter Housing is designed and manufactured to an international standard size of 1:1, allowing the bag to fit into the support basket without folding or wrinkling. 100% of the effective filtration area is freed up to ensure that the filtration efficiency is exactly the same as the design flow rate.
Polypropylene Bag Filter Housing for Long-Lasting Filtration
The Polypropylene Bag Filter Housing employs hydrodynamically optimized flow paths to provide a more even distribution of fluid to the filter bag, so that it is not subjected to fluid shock at any one point for long periods of time, resulting in breakage. This reduces the rate of differential pressure rise, extends the operating hours of the filter bag, and reduces the need for you to stop and change the filter bag.
Certification of Polypropylene Bag Filter Housing
Every Polypropylene Bag Filter Housing you receive has undergone rigorous quality testing and meets ISO and CE standards. Polypropylene Bag Filter Housing used in the food and pharmaceutical industries has even more stringent quality requirements and must meet FDA certification standards before it can be shipped to you.

Applications of Polypropylene Bag Filter Housing
Although Polypropylene Bag Filter Housing is not resistant to high pressure and high temperature, it has good performance on acid, alkali, solvent and other liquids. Therefore, it is often used in the following industries and applications:
Circulation filtration of electroplating baths for copper plating, nickel plating, gold plating, zinc plating and so on. Filtration of pickling and descaling solution in hardware or semiconductor processing, acidic/alkaline etching solution in PCB board manufacturing.
Intercepting tiny sediment, algae and suspended matters in seawater; pre-filtration in ultrapure water and deionized water system; clarification of various strong acidic and alkaline chemical wastewater.
Hydrochloric acid, dilute sulfuric acid, phosphoric acid, sodium hydroxide and other bulk chemical raw materials decontamination; liquid pesticides, chemical reagents, additives clarification and purification.
Various high-purity chemicals used in wafer cleaning process, particle interception of acid and alkali cleaning solution, and pre-filtration of CMP polishing solution.
Soy sauce, vinegar, brine and other high salinity liquids; clarification and filtration of pure water, fruit juice, beer, mineral water.
Interception of decolorized activated carbon in API production, clarification of chemical solvents; filtration of various acidic and alkaline pharmaceutical intermediates and traditional Chinese medicine extracts.

It is two different types of filter housing, Polypropylene Bag Filter Housing does not replace stainless steel filters. Because although Polypropylene Bag Filter Housing has strong chemical performance, strong corrosion resistance and is not easy to precipitate metal ions, the pressure and temperature it can withstand are not as strong as stainless steel filter. So you need to consider all kinds of conditions when choosing filtration equipment, each filter has its own disadvantages and advantages in the face of different working conditions, and you can choose the filter that is favorable to your working conditions.
It mainly depends on your liquid flow rate, usually size 2 Polypropylene Bag Filter Housing can handle a flow rate of 40m³/h and size 1 Polypropylene Bag Filter Housing can handle a flow rate of about 20m³/h. Secondly, you need to choose according to the height of your plant, the length of #2 bag is about 810mm, in order to ensure that the filter bag can be replaced, the height of the filter cover to the plant needs to be left at least about 850mm, while #1 bag is half of #2 bag, the height of the plant can be reduced accordingly.
You can choose a high capacity Polypropylene Bag Filter Housing according to your flow rate; secondly, choose a Polypropylene Bag Filter Housing with flow channel optimization design, which can make the pressure drop rise slower and less clogging, so naturally, the downtime for bag change will be reduced. Finally, by choosing a Polypropylene Bag Filter Housing with an easy-open lid/quick-open structure, it is easier to reduce the time needed to change the bag, thus shortening the downtime as well.
