High Efficiency Filter Bags
 General Use Filter Bag Series G
The 3M™ General Use Filter Bag features a multi-layered
polyolefin construction that provides clean, uniform, efficient
filtration at high flow rates in both low and high viscosity
liquids.
The bag comes in four nominal micron sizes to satisfy a wide
variety of filtration needs. A plastic collar/handle allows
for quick and clean filter changeouts and is designed to fit
into most existing bag housings. The large amount of surface
area provided by the layers of polyolefin media result in
high oilholding capacities.
High Performance Liquid Filter Bags
Series 100
The 3M™ Series 100 High Performance Liquid Filter Bag
is constructed of polypropylene melt blown microfibers, allowing
for very fine particle capture at high efficiencies. All 3M
Brand Series 100 Liquid Filter Bags are over 90% efficient
at their suggested application rating. The 3M
Filter offers an excellent balance of high efficiencies with
very low initial pressure drops. The bag construction makes
this filter an easy to use, convenient, high performance alternative
to filter cartridges. The 3M
Series 100 Liquid Filter Bag can also adsorb unwanted trace
oils that frequently occur in processed fluids. The high amount
of surface area due to the polypropylene microfiber construction,
results in oil holding capacities from 10-20 times the filter’s
own weight.
High Performance Liquid Filter Bags
Series 500
The 3M™ Series 500 High Performance Liquid Filter Bag
incorporates the patented bypass and transport layer design
that maximizes the amount of surface area in each bag. The
result is a unique filter designed to improve performance
and reduce operating costs. The 3M filter contains up to 38
square feet of usable filter media. Compare this with only
4.4 square feet for most competitive filter bags and 0.65
square feet for most competitive cartridges. To make use of
this entire surface area, the Series 500 Liquid Filter Bag
is constructed using the patented Bypass/Transport concept
invented by 3M researchers. Specially designed bypass holes
are cut into certain areas of the filter media to prevent
premature blinding of the filter. In conjunction with the
bypass design, a second media called a transport layer helps
to distribute fluid flow evenly through the filter. The outer
layers of the filter provide a highly uniform barrier for
final particle filtration. This construction results in very
high dirt loading capacity, even at high flow rates. There
are no sewn seams used in any of the filtering layers, thus
allowing high filtration efficiencies for fine particles.
The 3M Bypass/Transport filter technology is manufactured
in a filter bag form to provide additional operational advantages:
Changeout time – easier and faster, less labor required
Bag compressibility – easier and less costly disposal
Contaminant captured inside the bag – easier handling
The raw materials composing all above mentioned series are
FDA compliant according to CFR Title 21.
