Bag filter housings are essential components in industrial filtration systems, used to remove particulates from liquids across a wide range of applications. They are known by several names, each traditionally reflecting different designs, configurations, and uses. This article explores the different names and types of bag filter housings, providing insight into their applications and benefits.
Common Names for Bag Filter Housings
Bag filter housings are referred to by various names, often reflecting slight variations in design or application. Filter Sciences uses the phrase “Bag Filter Housing” most commonly, as this is the technical standard name, though many names and nicknames are used on site around the world. To clear up the confusion, here are the slight variations on these names, and what they may be referring to, though, it is important to remember that these names are essentially all referring to the same technology and filtration methods.
Bag Filter Pots: This term often refers to compact, cylindrical housings used for lower volume applications. These are typically found in smaller industrial settings or for pilot processes where space is limited. They are however, effectively the same as all other Housings.
Bag Filter Pods: Similar to pots, pods are compact units but may come in multiple configurations to handle slightly higher volumes or to accommodate specific installation requirements.
Bag Filter Vessels: This term usually describes larger units capable of handling high flow rates and large volumes. These vessels are robust, often made from stainless steel, and used in heavy industrial applications.
Sock Filter Housings: “Sock” is another term for the filter bag itself. Sock filter housings, therefore, refer to units that hold these filter socks. They are interchangeable with bag filter housings but emphasize form factor of the filter media.
Sock Filter Pots: These are generally smaller units designed for lower flow rates, similar to bag filter pots but specifically referencing the sock like media.
Sock Filter Vessels: These refer to larger units used in high-flow applications, emphasizing the use of sock filters for their filtration media.
Though originally, Bag Filter Housing – Bag Filter Vessel – Bag Filter Pot – Bag Filter Pod all used to denote specific traits of the filter, they are now commonly interchanged, and do not hold as much specific meaning as they once did. However, “Sock” has always been a generalized term, akin to a nickname.
Other Common Terminology
Beyond the most common terms, there are additional names and more specific designs that cater to particular needs:
Single Bag Filter Housings: As the name suggests, these housings hold a single filter bag and are ideal for applications with lower flow rates and where frequent maintenance is feasible.
Multi-Bag Filter Housings: These units can hold multiple filter bags, significantly increasing the filtration capacity and allowing for longer operation times between maintenance. They are used in large-scale industrial processes where continuous operation is critical.
Duplex Bag Filter Housings: These consist of two single bag filter housings connected in parallel. One housing can continue to operate while the other is serviced, ensuring uninterrupted filtration. This is particularly useful in critical applications such as in the chemical and oil and gas industries​.
Top Entry Bag Filter Housings: In these designs, the fluid enters from the top and exits from the bottom, providing easy access for filter bag replacement and maintenance.
Side Entry Bag Filter Housings: These housings have side inlet ports, making them suitable for installations with height restrictions. The horizontal flow design can also facilitate easier bag changes.
General Applications of Bag Filter Housings
Bag filter housings are incredibly versatile and find use in numerous industries. For detailed information on this topic, visit our home page, and explore our “Industries” tab in the main navigation. Some high level applications include:
- Chemical Processing: For removing particulate matter and purifying process fluids.
- Food and Beverage: Ensuring the purity of edible oils, beverages, and syrups, free from sediment and debris.
- Pharmaceuticals: For initial filtration of process water and some solvents.
- Water Treatment: Used in both industrial and municipal water treatment plants for particulate removal.
- Petrochemicals: For filtering oils, fuels, and even process water or salt water to remove contaminants and particulates​.
Bag filter housings, known by these various names and configurations, are crucial for effective, front-end industrial filtration. Understanding the different configurations and their specific applications can help in selecting the right housing for your needs. Whether referred to as bag or sock filter pots, vessels, or housings, these units provide reliable and simple filtration solutions across many industries.
