The length of the device will depend on the length of PP bag filter same as the diameter.
Which Material is used to make Polypropylene Bag Filter Housings?
Just as the name suggests, this device is made using propylene material.
However, not all parts of a Polypropylene Bag Filter Housing are made with this material.
Below are the materials used to make the housing and its related parts:
Housing and basket are made using polypropylene material.
Polypropylene material is chemical resistant.
The seal is made using Buna-N material
How do you Connect Polypropylene Bag Filter Housings to Piping Systems?
You can connect Polypropylene Bag Filter Housings to Piping Systems using a threaded or flange connection.
When installing the pipe connections ensure that they are stress free.
Avoid applying additional weight on the pipe connections unless a manufacturer explicitly states so.
Facilitating this connection has to be professionally and according to local and national codes and regulations.
What are the Components of Polypropylene Bag Filter Housings?
For a Polypropylene Bag Filter Housings to function efficiently on different operating conditions/applications, it must have some important components.
Parts of filter housing
These components include:
- Flanged inlet and outlet connections
- Top vent
- Bottom drain

- Gauge tap
What are the available Designs of Polypropylene Bag Filter Housings?
There are different designs of Polypropylene Bag Filter Housings:
· Multi-bag Filter Housing
Multi-bag filter housing
Multi-bag filter housing is built to hold greater flow rates and greater dirt capacities.
This housing comes with 2-23 bags or more.
It is suitable for solids loading application and higher flow rate.
Not all multi-bag filter housing is a single vessel holding multiple bags.
Some devices are a combination of several single-bag housings, connected together and controlled automatically or manually with valves.
The device, therefore, has a continuous flow filter solution enabling you to divert flow to one or more chambers during a bag change out.
With this design, an application would often need frequent bag changes and can operate with lower costs and maintenance times.
· Single Bag Filter Housing
Single bag filter housing
This Polypropylene Bag Filter Housing design is often constructed with polypropylene material. It has superior corrosion resistance, temperature capabilities and high-pressure.
Single bag filter housing avails technologically advanced filtration capabilities for different applications.
They come in different sizes, models, and pressure ratings.
It is suitable for smaller applications that require solid collections and a lower flow rate.
Single bag filter housing is less complex and highly economical.
How do you Install Polypropylene Bag Filter Housings?
The installation of Polypropylene Bag Filter Housings is easy.
First, you unpack the device and check for any damages.
Take the enclosed data sheets, operating instructions, and illustrations read carefully and then set aside for future use.
Ensure that all the accessories are enclosed.
Also, remove the plastic protective caps from the included flanges.
When installing this device, ensure that you do not reverse the inlet and outlet.
At times, the inlet and outlet may not be market.
In such cases, you should note that the inlet is positioned above the outlet which is often at the bottom.
This inlet allows the flow of liquid into the filter bag so that the direction of flow is from the inside to the outside.
Facilitate secure installation by efficiently bolting the device to the bag filter.
You do not need a separate base frame when installing this device since the housing is built to stand vertically without falling/tipping over.
You have to integrate the device into the right piping system.
You connect the housing to the piping system via a connection to facilitate the flow of liquids during filtration.
Installation onsite is easy because the client gives the parameters such as length, position and diameter.
What should you Consider when Choosing Polypropylene Bag Filter Housings?
You should consider the following aspects when choosing these bag filter housings:
i. Material of Construction
The grade of polypropylene used has to be of high quality.
Besides, the material chosen to make the other parts of the device should be high quality, chemical compatible and meets the FDA regulations.
ii. Operating Conditions
The type of device that you pick must function effectively in the application conditions.
In seawater applications where the conditions increase the risk of rusting, then polypropylene bag filter housing is the best device.
In this case, Steel Bag Filter Housing is not a good option.
iii. Connection Types
When choosing a Polypropylene Bag Filter Housings, you have to pick one that has the suitable connection type.
It could have a flange or threaded or socket connection.
