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.
