Oltre 1 micron pleated filter canister (CF370): 370mm or 510mm dia upgrades for dust collectors. Fine dust capture, constant CFM.

Upgrade your dust extraction system with the Oltre One Micron Upgrade Cartridge Filtration Canister, available in two sizes to suit various dust collectors: the compact 370mm diameter x 500mm height (OT-FC-370) or the larger 500mm diameter x 610mm height (OT-CF-510A). This 1 micron pleated filter canister replaces standard top bags, capturing ultra-fine dust while maintaining consistent CFM for superior airflow in woodworking shops.​

The pleated cartridge design provides significantly more surface area than traditional bags, reducing clogs and cleaning frequency during heavy use with MDF, plywood, or hardwoods. Both variants ship in protective boxes with dimensions optimized for the 370mm model (420x420x600mm) and 510mm model (560x560x700mm), ensuring easy integration into 1HP or 2HP single-bag systems.​

Ideal for Australian workshops seeking HEPA-class filtration without full cyclone upgrades, the CF370 series improves air quality and machine efficiency. Select your size based on collector compatibility for cleaner, safer operations with stationary machinery and hand tools.​
