Performance Data Notes:
1.Nominal air quantity based on 90 fpm velocity and the module’s gross face area.
2.All fan motors are 1/3 hp single phase; 1570 rpm at 115, 230 and 227V 60Hz, and 1310 rpm at 230V
50Hz. Full load amps: 2.4 at 115V; .94 at 230V and 277V, 60Hz.
3.Based at 80% of nominal air quantity.
4. Weights: 24x48: Std.= 66 lbs, RSR = 92 lbs.
1.0 General
1.1 Fan-Powered Terminal HEPA/ULPA Filter
Modules shall be Pureflo-FPM as manufactured
by Flanders.
1.2 Modules shall be UL listed as a complete unit.
1.3 Module sizes, electrical characteristics, efficien-
cies, capacities, and options shall be as scheduled
on the drawings.
2.0 Module Construction
2.1 Filters shall be the separatorless minipleat type
scan-tested after assembly to meet IEST RP-1
requirements. The filter’s protective grille shall be
expanded 20 ga. steel white powdercoat painted.
2.2 Filters for STD models shall be 2.1” (53 mm), and
shall be sealed into an anodized aluminum frame.
Filters for RSR models shall be 2.76” (70 mm) and
shall incorporate an extruded aluminum frame
with a gel and knife edge seal design
2.3 Fan housing shall be mill finish .063” aluminum.
2.4 The integral fan/motor assembly shall consist of a
backward-curved centrifugal fan with sealed bear-
ings, direct-driven by a single phase 1/3 hp PSC
continuous duty thermally protected motor.
2.5 Motor speed shall be controlled by a solid state
speed controller.
3.0 Performance
3.1 Modules shall produce HEPA or ULPA filtered air
at a velocity of 90 fpm + 15 fpm 6” below the filter
face.
3.2 Using the solid state speed control, the sound
level 30” from the filter face shall be approximate-
ly 53 dbA at 90 fpm average face velocity and less
than 25 dbA ambient sound level.
