When setting up an industrial filtration system, one of the most critical choices is whether to use filter housings with filter cartridges or filter bags. Both options are widely used across numerous industries and applications, but they work in different ways to achieve slightly different results.
Precision Filtration is a trusted manufacturer of advanced liquid filtration systems and waste minimization solutions. Our goal is to help you determine whether a bag filter housing or a cartridge filter vessel is best suited for your specific application.
Filter Bag Housings
Also known as filter bag vessels, these housings are designed to enclose a filter bag within a liquid stream. The bag captures contaminants, particulates, and other impurities as the liquid flows through. Once filtered, the purified liquid continues through the system. Because the filter bag is easy to replace, this design helps reduce maintenance costs and prolong the lifespan of expensive equipment.
Advantages of Filter Bag Housings
Filter bag housings are user-friendly and can be opened easily without special tools, allowing for quick cleaning or bag replacement. They generally experience low pressure drops and come with permanently piped housings for reliability.
These housings are available in multiple configurations—single filter housings, multi-basket, cartridge, duplex, and multiplex units—to suit different system setups. For applications dealing with larger solid particles, bag filter housings often outperform cartridge systems in efficiency and cost-effectiveness.
Common Industrial Applications
Bag filter housings are used throughout various industries for their durability and adaptability. When choosing one for your process, consider:
·Maximum operating pressure and temperature
·Chemical and physical compatibility
·Type of filtration duty
·Type of contaminants to remove
·Desired flow rate
Each of these variables influences the best filter bag housing for your operation.
Filter Cartridges
Filter cartridges are designed to trap contaminants and remove fine particles from water or industrial liquids. As the unfiltered liquid enters the cartridge, impurities are captured while the clean fluid continues downstream. Cartridges can be constructed from a range of materials—including stainless steel—to meet the demands of different industrial environments.
Advantages of Cartridge Filtration Systems
Cartridge filter vessels are highly versatile, offering significant flow capabilities while maintaining easy cleaning and maintenance. They are ideal for applications that prioritize hygiene and precision.Depending on their construction, cartridges can support surface filtration or depth filtration, making them an excellent choice for capturing small particles with high accuracy.
Industrial Applications for Filter Cartridges
Cartridge filters are especially valuable in industries that require consistent product purity, such as:
Food and beverage processing
Water purification
Cosmetics and personal care
Pharmaceutical manufacturing
Electric utilities
Hydraulic fluid systems
Bulk chemical processing
Wherever liquid purification is critical, cartridge filters provide dependable performance.
