Superflow 2K Performance
The Superflow 2K filters offer HEPA efficiency at an
ultra low pressure drop for HVAC systems supplying
air to critical areas.
Figure 1 illustrates the Superflow 2K pressure drop
as a function of air flow rate for gasket seal and gel
seal designs.
Superflow 2K Selection
All products have a rated overall efficiency of
99.99% at 0.30 µm and a maximum pressure drop of
1.0 inch w.g. at the rated flow. Specify the following:
Material Types: 8 = Galvanized
5 = Aluminum
3 = Stainless Steel
Gasket Types: G = Neoprene F = Blu Jel
Gasket Locations: 1 = Upstream 2 = Downstream
1.0 General
1.1 HEPA filters shall be Flanders Superflow 2K as
manufactured by Flanders.
1.2 Filter sizes, efficiencies and capacities shall be
as specified on the drawings.
2.0 Construction
2.1 Filters shall be constructed with ten 1” pleated
media packs arranged in a V-bank configuration.
The media packs shall be formed by pleating wet
laid micro-fiberglass media with continuous
beads of a nonvolatile adhesive spaced 1-1/4”
apart.
2.2The filter frame shall be 20 ga. galvaneal steel and
shall consist of eight C-channel supports
attached without the use of mechanical fasten-
ers. The media packs shall be sealed around the
entire periphery to the frame with a two compo-
nent polyurethane.
3.0 Performance
3.1 The minimum filter efficiency shall be 99.99% at
0.30 µm when tested with polydisperse DOP
aerosol at the rated air flow.
3.2 The maximum pressure drop shall be 1.0” w.g. at
the rated air flow.
