Donaldson DBA5294 Primary Air Filter Assembly

The Donaldson DBA5294 is a primary panel-style air filter element featuring Donaldson Blue Ultra-Web nanofiber media technology. Designed for Fleetguard Direct Flow air cleaners, it delivers 99.99% filtration efficiency per ISO 5011 test standards. The filter utilizes a radial seal design with urethane-sealed pleat ends for leak-resistant sealing. It serves as a direct replacement for OEM filters used on Cummins QSB3.3, QSB4.5, and QSF series engines. Key construction includes a panel configuration with dimensions of 189.3 mm length, 233.5 mm width, and 321 mm height. The nanofiber media provides superior dust holding capacity and lower restriction compared to conventional cellulose media. This filter is engineered for high-dust environments typical in construction, agricultural, and material handling applications.
