FEATURES & BENEFITS
Wheels
Fumex fans oer patented wheel designs. Carefully matched, highly-tooled venturis enhance the performance of these backward inclined
and non-overloading centrifugal wheels. Made of advanced aluminum alloys, the various wheel components provide superior strength
and durability, as well as spark resistant construction. The heat and smoke removal conguration utilizes steel construction.
Standard Duty, All Welded Wheel
(Standard Duty & High Pressure Belt Drive)
• Blades are curved for improved air performance while increasing their strength and rigidity.
• Backplate and inlet are stamped for consistency. They include a perimeter rim which enhances strength and improves balancing.
• Wheel assembly is robotically welded to provide extremely durable and consistent performance.
• Wheel is dynamically balanced. Balancing weights are mechanically attached to the inside of the rims of both the backplate and
wheel inlet. This allows a precise placement of the weights anywhere within a full 360º range on two separate planes, without the
possibility of detachment.
Enhanced Direct Drives
These enhanced units have Gplus™ motor selection up to 2 HP (available on single phase and three phase) and are available up to size
24. Design enhancements to Direct Drive Fumex models signicantly improve air performance, while Gplus™ EC motors oer higher
eciency, and quieter, more reliable operation. Combined with PennBarry’s patented, backward inclined, centrifugal wheel, these fan
units deliver low noise and high eciency performance.
Internal Wiring
All direct and belt drive models with ODP motors feature a polarized disconnect plug which is factory wired from the motor to the
junction box. This provides a positive method of electric shut-o as required by most codes without requiring the traditional disconnect
switch. In addition, weather resistant NEMA 3R wiring is available for selection.
Reverse Venturi
Reverse venturi reduces turbulence and improves distribution of the air as it enters the wheel
inlet and is “captured” by the blades.
Silent Wheel (Direct Drive)
• Blades’ highly curved leading edges provide unsurpassed low sound numbers with excellent
air performance.
• Backplate and inlet are stamped for consistency, plus dynamic balancing ensure smooth,
vibration-free operation.
• Riveted or riveted and welded construction ensure superior dependability over other wheel
designs.
