Best Air Filters for Industrial Equipment: Fit, Flow and Filtration Questions

Start with the outside diameter, inside diameter, height, filter area and required flow. The cartridge uses folded wood-pulp filter media, electro-galvanized end caps, a galvanized diamond-mesh center frame and a closed-cell neoprene sealing ring. These details help define whether the cartridge suits the housing and sealing arrangement.

For example, model ON-3260 measures 320 mm in outside diameter, 220 mm in inside diameter and 660 mm in height. Its filter area is 10 to 25 m², its flow is 600 to 1,250 m³/h, and its filtering efficiency is 99.99% at 2 µm. A buyer replacing a compressor or turbine intake cartridge should compare these figures with the existing housing and required air volume before ordering.

Yes. The cartridge is used for gas turbines, compressors, sandblasting, fly ash, floating dust and other air or gas filtration applications. Its wide-fold design provides a large filtering area. The cellulose media is described with small pore size, high air permeability, low resistance and high efficiency.

The galvanized protective components support the cartridge structure, while the closed-cell neoprene sealing ring provides the sealing interface. In a dust-handling installation, picture the cartridge inside its housing during airflow: measure the available space and check the sealing arrangement before selecting a model. The product description specifies use at normal temperature, so send the actual operating condition with the equipment details when requesting a match.

The listed range includes outside diameters of 320 mm, 350 mm, 408 mm and 440 mm, with several height options. Model ON-4088 measures 408 mm in outside diameter, 292 mm in inside diameter and 880 mm in height. It has an 18 to 35 m² filter area, a flow range of 1,050 to 2,120 m³/h and filtering efficiency of 99.99% at 2 µm.

Use the current cartridge as the starting reference. A replacement order should include the equipment model, current outside and inside diameters, height, required airflow, filtration target, application and quantity. A housing photo or drawing can also help clarify the fit and sealing interface. Send those details to ONLY Technology (hebei Province) Co., Ltd. when requesting a quotation.
