The work area will influence the size of this system.

Also, the unique needs of the environment will influence your choice.

Ensure you select a filter housing that meets international standards and integrity tests.

Make sure the work area can accommodate the filter housing.


Ensure the filter housing is within your budget since the cost incorporates

  1. Purchasing
  2. Maintenance
  3. Installing
  4. Extra features

Model and Design

Ensure you buy the correct model and series of the filter housing as varying usages apply different filters.

For example, some designs allow you to place filters at the top, bottom, inside, outside, etc.

Selecting the correct filter housing model and design ensures it works well with your system.

The wrong filter housing will result in incompatibility issues.

Mounting Processes

Installing a filter housing impacts the efficiency and cost of the unit.

For example, systems that need varying fluid cleanliness levels require small filters at the point of usage.

This enables you to achieve an effective filtration than a central installation.

Ensure the installation is in a visible location as it enables one to conduct maintenance easily.

Consider the pressure drops when sizing the unit.

How Can you Test for Leakages in Cartridge Filter Housing?

Here are the steps to test for leakages:

  • Step one

Connect the cartridge filter housing to a gaseous helium tank.

  • Step two

Dip the filter housing underwater and increase the pressure of the helium supply steadily.

  • Step three

Perform this test at 25%, 50%, 75%, and 100% of the maximum working pressure that is allowable.

Continuously monitor the production of bubbles.

  • Step four

When the production of bubbles occurs for over one minute, this illustrates that the cartridge filter housing is leaking.

What are the Factors that Will Determine the Configuration of a Cartridge Filter Housing?

The performance of a cartridge filter housing is directly proportional to its size.

This means that bigger filter housing will perform better.

Here are some factors that will influence the configuration of the cartridge filter housing:

  • Filtration efficiency

What Materials Are Used to Make a Cartridge Filter Housing?

Several materials can make this system and it depends on the needs of your filtration process.

These materials include:

Carbon Steel

This material contains carbon and iron alloys and other materials present are copper, silicon, and manganese.

Its strength depends on the quantity of carbon you add and the different grades of carbon steel include:

  1. Mild carbon steel
  2. Medium strength
  3. High carbon steel

Stainless Steel

This is among the best materials and it has carbon in low quantities of between 0.03% to 1% with iron.

Adding chromium [at least 11%] will enhance the resistance of this material to corrosion.

Depending on the amount of alloy you add, stainless steel comes in different grades like 200, 300, or 400.

Grade 300 stainless steel offers the best corrosion resistance.

Some examples include 304 and 316 stainless steel

Plastic Housing

These are appropriate for use in highly corrosive environments, low pressure, and flow rates.

They are conducive to lightweight, non-corrosive substances, cheap, and can function at high temperatures.

The construction can be of:

  1. Polypropylene
  2. Polyvinylidene difluoride [PVDF]
  3. Nylon
  4. PTFT

PTFT Housing

This is resistant to chemicals and also comes with stainless steel support bars on the exterior.

They are hydrophobic thus suitable for making membrane housings that will eliminate water from gas streams.

Aluminum Housing

They are lightweight and good for a wide array of applications.

However, they are not durable and are weak than steel or carbon steel, and are susceptible to chemicals.

How Does a  Low Pressure and High Pressure Cartridge Filter Housing Compare?

High-pressure cartridge filter housing can handle high pressure and heat as they are durable.

Also, high-pressure cartridge filter housings are costly than low-pressure cartridge filter housings.

Low-pressure filter housings are suitable for low-pressure environments.

What is the Cleaning Process of a Cartridge Filter Housing?

They are:

  • Manual
  • Automatic
How Can Improve the Efficiency of a Cartridge Filter Housing?

Repair or replace all broken or faulty parts with new and genuine parts.

Use lubricants to minimize tear and wear and seal all joints to eliminate leakages.

Completely shut down the system before opening it.

Regularly clean the components to minimize the build-up of dirt.

How Does a Duplex and Simplex Cartridge Filter Housing Compare?

One can use a simplex cartridge filter housing in several applications.

Also, it is simple to open and clean thus lowering downtime

A duplex filter housing is suitable for the continuous filtration process meaning you cannot stop the process midway.

Duplex filter housings are durable with a long service time since they have a high dirt holding capability.

What Factors Influence the Price of a Cartridge Filter Housing?

They are:

  • Pressure rating
  • Flow rating
  • Construction material
  • Size
