Disposable cartridge filters are filtration devices used in various industries and applications to remove contaminants and impurities from liquids or gases. These filters are designed with a convenient and user-friendly "plug-and-play" concept, allowing for easy installation and replacement. The filter cartridges are typically constructed with high-quality filter media, such as pleated polypropylene, activated carbon, or other specialized materials, to effectively capture and retain particles, sediments, microbes, or chemicals present in the fluid or gas stream. Disposable cartridge filters offer several advantages, including cost-effectiveness, time savings, and reduced maintenance. They eliminate the need for cleaning or reusing filter elements, as the entire cartridge is replaced when it reaches its filtration capacity. This ensures consistent filtration performance and avoids the risk of cross-contamination between different process streams. Disposable cartridge filters are widely used in food and beverage, pharmaceuticals, biotechnology, and water treatment industries, where reliable and efficient filtration is critical for product quality, process efficiency, and regulatory compliance.

Bag filters are one of the most economical ways to remove solids from liquids at moderate to high flow rates. A filter bag sits inside a pressure vessel, captures particles and is simply swapped out when full.
Bag Filter Products
- Filter bags – felt and mesh in polypropylene, polyester and nylon
- Single bag vessels – compact filtration for lower flows
- Multi-bag vessels – high flow and long service life
- High-efficiency bags – absolute-rated and oil-absorbing options
- Baskets and seals – replacement parts for housings
Choosing a Bag Filter
Select micron rating, media and bag size based on the fluid, particles and flow rate. Choose vessel material (carbon steel, stainless, plastic) for pressure and chemistry. Swing-bolt closures simplify bag changes.
Centro supplies bag filters and vessels for water, chemical and process liquid filtration.

- Manufacturing plants use a variety of filtration systems depending on the media being filtered and the contaminants being removed. Liquid filtration systems — including bag filters, cartridge filters, and automatic self-cleaning strainers — remove particulates from process water, chemicals, coatings, and other fluids to protect equipment and maintain product quality. Gas filtration and separation systems remove particulates, oil aerosols, water vapor, and other contaminants from compressed air and process gas streams to protect pneumatic equipment, instrumentation, and downstream products. Strainers (Y-strainers and basket strainers) are installed in pipelines to catch large debris that could damage pumps, valves, and control equipment. Dust filtration systems — including dust collectors with cartridge or bag media — capture airborne particulates generated by grinding, sanding, cutting, conveying, and material handling operations to protect workers and meet OSHA air quality standards. Filter housings hold the filter elements and provide the pressure containment needed for the application's flow rate and operating conditions.
- Bag filters and cartridge filters are both used for liquid filtration, but they differ in design, capacity, and application fit. A bag filter is a flexible fabric or felt pouch that sits inside a filter housing — liquid flows from outside the bag through the media to the inside, trapping particles on the outer surface and within the media. Bag filters handle high flow rates, are cost-effective per unit of filtration area, and are easy to change. They are the standard choice for applications with moderate to heavy particle loads where micron ratings of 1 to 200 microns are sufficient — such as water treatment, chemical processing, paints, and food and beverage production. A cartridge filter is a rigid or semi-rigid cylindrical element (pleated, wound, or melt-blown media) that typically provides finer filtration and higher efficiency than bag filters, with ratings available down to sub-micron levels. Cartridges offer more surface area in a smaller footprint, making them ideal for applications requiring tight particle control, lower volume flows, or polishing filtration after a coarser first-stage filter.
- Filter media material selection depends on the fluid chemistry, temperature, particle characteristics, and regulatory requirements. Polypropylene is the most widely used industrial filter media — it offers broad chemical compatibility (resistant to most acids, bases, and solvents), is FDA compliant for food and beverage applications, and is cost-effective. It is available in melt-blown, spun-bonded, and pleated configurations. Polyester provides higher temperature resistance than polypropylene (up to approximately 300°F) and excellent mechanical strength, making it well suited for higher-temperature liquid applications. Nylon (polyamide) offers good chemical resistance and is commonly used in monofilament woven mesh bag filters for applications requiring precise pore-size surface filtration and bag reusability. Stainless steel mesh and sintered metal media are specified for high-temperature, high-pressure, and aggressive chemical applications where polymer media would degrade. Nomex is used in high-temperature applications such as hot oil filtration and dust collection at elevated temperatures. PTFE media provides universal chemical resistance for the most aggressive acids and solvents. Always verify the media material's compatibility with your specific fluid and operating temperature.
- A filter housing is the pressure vessel that contains the filter element (bag or cartridge) and provides the connections for inlet and outlet piping. The housing seals the process fluid inside, directs flow through the filter media, and allows operators to access the element for replacement. Choosing the right housing involves several factors: the number and size of filter elements it holds (which determines flow capacity), the pressure rating (must exceed the maximum system pressure plus a safety margin), the material of construction (carbon steel for general industrial service, stainless steel 304 or 316 for corrosive fluids, food-grade, or pharmaceutical applications), the connection type and size (NPT threaded, flanged, or sanitary tri-clamp), and the element type it accepts (standard bag sizes #1 through #4, or specific cartridge lengths of 10, 20, 30, or 40 inches). Single-bag housings are the most common for moderate flow rates, while multi-bag housings handle higher flows. Multi-cartridge housings hold several cartridges in parallel for high-volume, fine-filtration applications. Always size the housing to handle peak flow without exceeding the recommended differential pressure.
- An automatic self-cleaning filter continuously removes captured contaminants from its filter element without shutting down the flow or requiring manual intervention. When the differential pressure across the element reaches a setpoint (indicating the element is loaded with contaminants), the system automatically initiates a backwash, scraper, or suction-scanning cycle that cleans the element and discharges the collected debris to drain. The filtered process flow continues uninterrupted during cleaning. Automatic self-cleaning filters are the right choice when the contaminant load is heavy and continuous — meaning manual filter bag or cartridge changes would be required so frequently that labor cost, downtime, and waste disposal become impractical. Common applications include cooling water systems, river or well water intake protection, wastewater reuse, industrial process water loops, and any high-volume, continuous-flow application where filter element changes multiple times per day would be operationally burdensome. The higher upfront cost of an automatic filter is offset by dramatically reduced labor, filter media consumption, and downtime compared to manually changed bag or cartridge systems in heavy-duty service.
