Cartridge Technology

EZ Ultra-Web II cartridges feature Eon™ Fine FiberTechnology by Donaldson. Eon microfibers ensurelongest filter life and highest filtration efficiency.

The ExtraLife filter cleaning system uses proprietaryventuries to deliver more cleaning energy. The result islonger filter life and more reliable performance. The graphshows pulse energy measured one inch from the tubesheet.ExtraLife technology is in blue; conventional technology isin black.

Competitive media has no surface layer of microfibers.(Competitive media magnified 600X.)

Easy to Maintain

Octagonal hopper with no internal ledges prevents bridgingand plugging problems.

Drum Sentry™ indicates when drum is full.

Inclined cartridges and quick removal access covers for easyfilter changeout.

Control Panel Options

The Checker™ board ControlPanel provides color-codeddiagnostic data.

The Torit Delta P Control providesfilter restriction and cleaningcontrol at the set points you choose.
