Stainless steel pleated filter cartridges and self-cleaning backwash filter elements — reusable, high-flow, designed for demanding industrial filtration applications.
About This Category
Pleated filter cartridges use a corrugated filter media geometry that increases effective filtration area by 3× compared to cylindrical wound filters. The result: higher flow rates, lower pressure drops, and longer service life between replacements.
Our pleated filters are manufactured from SS316L stainless steel with multi-layer support structure. Suitable for temperatures from -268°C to +371°C and compatible with a wide range of acids, solvents, hydrocarbons, and industrial chemicals. All units undergo passivation testing before shipping.
Standard Pleated
SS316L stainless steel construction. Reusable, high filtration area, pleated geometry reduces pressure drop at high flow rates. Ideal for petrochemical, hydraulic systems, and water treatment.
Self-Cleaning
Self-cleaning design with periodic reverse-flow cleaning — no need to shut down or remove the element for cleaning. Built with stainless steel mesh or reinforced basket structure for high solids loading and continuous operation.
Quick Comparison
| Product | Cleaning Method | Best For | Max Temp | Max Pressure | Structure |
|---|---|---|---|---|---|
| Pleated Filter Cartridges | Manual backwash / chemical clean | Batch processes, intermittent flow | 371°C | 17 bar | Corrugated SS316L media |
| Backwash Filter Cartridges | Self-cleaning, automatic reverse flow | Continuous flow, high solids loading | 300°C | 25 bar | Stainless steel mesh / reinforced basket |

Common questions about pleated filter selection, backwash systems, and our ordering process.
Need help selecting the right filter?
Our engineering team reviews your application details and helps you confirm the right configuration — before you place an order.
Talk to an engineer arrow_forwardMaximum forward differential pressure is 250 psid (17 bar). Reverse differential pressure should not exceed 50 psid (3.4 bar). Exceeding these limits may cause media deformation or collapse.
DOE (Double Open End): Flat gasket on both ends, most common and widely compatible. 222: Fin on the closed end, tab on the open end. 226: Threaded bayonet style, strongest mechanical seal. Connection must match your housing.
Yes. Backwash cleaning with compressed air or compatible liquid is recommended. Avoid harsh chemicals that damage seal materials. Inspect the media after each cleaning cycle.
Backwash filters allow periodic reverse-flow cleaning without removing the element. Standard pleated filters require manual removal for cleaning. Backwash filters are ideal for continuous operation systems.
Approximately 1.8 ft² (0.17 m²) per 10-inch length. A 20-inch cartridge provides roughly 3× the flow capacity of a 9.75-inch cartridge in the same housing.
EPDM (-40°C to +135°C), NBR (-30°C to +120°C), Viton/FKM (-20°C to +200°C), Silicone (-60°C to +230°C). Match to actual operating temperature, not nominal range.
Choose pleated filters for batch processes or intermittent flow. Choose backwash filters for continuous-flow systems, high-solids loading, or when shutdown for replacement is costly.
5–10 μm for general pump/motor protection. 3–5 μm for sensitive servo valves. 10–25 μm for coarse pre-filtration. Consult your hydraulic component manufacturer's specifications.
