Domex Series of Centrifugal Fans Domex Direct & Belt Drive Fans Domex fans are ideal for general purpose exhaust applications PennBarry certifies that the Domex direct drive including: bathrooms, garages, general kitchen areas, offices, and belt drive models shown herein are licensed churches, dormitories, factories, large warehouses and other to bear the AMCA seal.

2 The ratings shown are relatively clean air applications. based on tests and procedures performed in accordance with AMCA publication 211 and AMCA. They feature a weather-resistant, seamless spun aluminum publication 311 and comply with the requirements housing which works in conjunction with a patented wheel of the AMCA Certified Ratings Program. design and deeply spun inlets to provide smooth quiet air flow through the ventilator. The Centrifugal wheels are aluminum, Domex High Capacity Belt Drive Fans nonoverloading, backward inclined, robotically welded, and PennBarry certifies that the Domex high capacity dynamically balanced.

Motor Selection Self-Aligning Bearings Both direct drive and belt drive models are available with a wide Heavy-duty bearings are sized for a minimum L50 life in excess range of voltages and enclosures (see Motor Selection for a of 200,000 hours of operation.)

5 100% factory tested, they are complete listing). Standard belt drive Open Drip Proof (ODP) designed for air handling applications. ball bearing motors are selected using a conservative portion of the NEMA service factor. Standard direct drive ODP motors Drives and Belts have Class B insulation and internal thermal overload protection. Pulleys are pre-set to the specified RPM. Cast iron variable pitch Each size is carefully engineered to match the motor to the wheel pulleys are adjustable, allowing for field balancing based on capacity. actual field conditions.

6 All pulleys are sized for at least 150% of the driven horsepower. Internal Wiring All direct drive models with ODP motors feature a polarized Vibration Isolators disconnect plug between the motor and junction box. This Multidirectional, rubber-in-shear vibration isolators mitigate provides a positive method of electric shut-off. Belt drive units residual vibration transmission from the unit to the building. with ODP motors are factory-wired between the motor and junction box. For either direct drive or belt drive models, an electric disconnect is available.

7 Conduit Both direct and belt drive units include a large 1 nominal conduit Sound Performance chase for easy installation of wiring from the motor dome to below the curb cap. Units deliver outstanding air performance with minimal noise. Reverse Venturi Curb Caps (Base). Reverse venturi reduces turbulence and Curb caps for direct drive and standard duty belt drive models are improves distribution of the air as it enters available in galvanized steel (standard) or aluminum (optional). the wheel inlet and is captured by the Curb caps for high capacity belt drive models are available only blades.

8 In aluminum. All curb caps have fully welded corners and are pre- punched to ensure both a leak-tight and easy installation. Aluminum Wheels Forced Motor Cooling Domex fans offer patented wheel designs. Carefully matched highly-tooled venturis Breather slots between the motor dome and discharge apron enhance the performance of these backward enable fresh air to be drawn into the motor housing during fan inclined and non-overloading Centrifugal operation. This positive cooling promotes longer life for motor wheels. Made of advanced alloys, the and drive components.

9 Various wheel components provide superior strength and durability. Easy Maintenance Access By removing the fasteners, the motor dome lifts off for complete Silent Wheel (Direct Drive). access to all the drive train components. Blades' highly curved leading edge provide unsurpassed low sound numbers with excellent air performance. Structural Integrity Back plate and inlet are stamped for consistency, plus dynamic Durable housings of spun aluminum have a high strength-to- balancing assure smooth, vibration-free operation. weight ratio and incorporate a rolled bead for additional strength.
