Note: Filter housing selection should also be considered when flow rate per cartridge is determined.
Lower pressure drop for higher flow rates
Flow-Max ® cartridges are pleated, so initial pressure
drop is significantly less compared to depth cartridges,
such a wound, spun, melt blown and resin bonded.
As a result, higher flow rates are possible, reducing
filter housing size requirements to lower capital
equipment costs.

Washable & reusable
Flow-Max ® cartridges are washable
and reusable, five micron and up
to reduce filtration costs. For best
results, direct spray into pleats
to dislodge sediment. Or, let
dry and brush off filter cake
from surface of the media.
All Flow-Max ®`
cartridges are
individually shrink
wrapped for purity
