bag -sized cartridge

shanghai stablefilter has combined the best features of filter bags and cartridges into one single
unit. Like bags, these bag-sized pleatedcartridges are easy to handle and trap
contaminant inside, preventing OFF" when removing spent or dirty cartridges.
Like cartridge elements, they provide larger surface areas and greater dirt-holding
capacities than standard bags. They are the ideal solution when frequent
servicing of filters is a problem.

shanghai stablefilter  bag-sized pleated cartridges are unique. Twenty-five* square feet of high
efficiency material is sandwiched between two flow-enhancing, coarse-mesh screens,
and then pleated in a supported construction. This supported pleat
construction ensures flow cannot be pinched off. It also greatly strengthens
the overall integrity of the element. The seams in these units are ultrasonically
welded, not sewn, to prevent leakage or contamination bypass. The top sealing
ring and cartridge bottom, made of solid molded polypropylene, are sonically welded to the pleated cylinder.

Features
■ Eleven micron retention ratings from
1 to 110 at 95% efficiency, are available
■ Three different top sealing ring designs -
one to fit your needs
■ As/ailable in standard bag sizes 1 and 2,
to fit housings 8-15 and 8-30
■ Low pressure drop

Means Longer LifeFILTRATION LEVELThese elements have been tested using
the Single-Pass Efficiency Test (see diagram) using water and AC Fine lest
Dust. Water is passed through an initial pre-filter (at 0.45 卩)，after which
contaminant is injected into the waterline. An automatic particle counter
analyzes the number of particles permilliliter greater than a selected size,
before the water enters the filter.The water then passes through the test
filter; and the effluent is analyzed for the number of those same-size particles.
The number of particles removed provides the efficiency rating. For
example, if after the single pass, 95 percent of the particles are removed,
then the filter is 95 percent efficient at the specified micron rating.
FILTRATION EFFICIENCY Using the single pass efficiency test,
we've determined the following efficiency ratings for our pleated cartridges. Real
ratings are consistently accurate and reliable, time and time again.
