The TOPLINE model bag filter housing is the
highest performance design we offer. Especially if your
application requires ≤25 micron nominal retention or an absolute
(99%) efficient rated retention, the TOPLINE bag filter is the
best choice. Offered in both carbon steel and 316 stainless
steel, TOPLINE bag filters have 2" 150# ANSI flanged connections and
are rated for a maximum pressure of 150 PSI at 400F. There is
also a variation referred to as the "Santary TOPLINE" having all
tri-clover connections with a interior surface polished to 0.8 Ra
micrometers (32Ra microinch) and an electo polished external finish.
TOPLINE bag filter housing are custom fabricted and can be provided
with an ASME UM code stamp (not applicable to the sanitary model).
The
primary difference between the TOPLINE bag filter housing and the
other models we offer is the "over-the-top" or "goose neck" inlet configuration.
This feature allows for the chamber cover to directly compress the
filter bag seal, thereby forming the best seal possible. When
combined with the
SENTINEL filter bag style sealing ring, the
TOPLINE will provide "bypass-free" performance. The Sentinel style sealing ring can also be referred to as crushed
sealing ring, as the compression of the ring forces the angled
portion of the ring to "crush into" the machined sealing groove.
This "crush seal" is superior to a
SNAP-RING filter bag seal or flanged ring relying on a
gasket or o-ring for a good seal. All of the absolute rated
filter bags utilize the SENTINEL style bag seal and it is really
essential for any filtration requirement
≤25 microns.
Another advange of the inlet configuration is a smooth inlet transition, the resulting turbulence entering the filter bag is reduced and the laminar flow sends the larger particles directly to the bottom of the filter bag. The hinged chamber cover has two sealing gaskets, one for the inlet and the other for the filter bag chamber and they are availalbe in Buna-N (inclulding food grade Buna-N), Viton, EPDM, PTFE encapsulated Viton and Silicon.
TOPLINE bag filter housings can be used with HAYFLOW restrainer baskets and filter bags for nominally rated filtration applications from 1 to 100 microns. Using the HAYFLOW configuration increases the maximum flow rate from 130 GPM to 200 GPM because the available filtration surface area is increased by 70%.
If your flow rate requirements exceed 200 GPM or one #2 sized absolute rated filter bag cannot handle your flow, we offer versions of the TOPLINE having from 2 to 8 filter bag chambers.
