Model HDBC: Backward Curved Fan

Features

• All models available with housing and wheel widths from 50% to 100%, in 5% increments, to deliver the performance you need with a direct driven blower.
• Continuous welded housings, instead of lock seams, eliminate air leakage.
• Heavy gauge steel bases, with internal bracing, maximize rigidity and promote long equipment life.
• Blower housings can be rotated in 45° increments, on sizes 300 and smaller, to provide increased configuration flexibility in the field.
• Removable inlet & drive side plates allow for removal of blower wheel or motor, or shaft and bearings on belt driven models, without disconnecting inlet or discharge connections.
• Inlet side support assures a minimal vibration housing.
• All fans receive a mechanical run test to ensure proper balance and alignment before shipping.
• Belt driven models include heavy duty, grease lubricated, self-aligning, cast iron, and pillow block bearings selected for optimal performance.
• Fan shaft on belt driven models is turned, ground, and polished and receives a high-quality rust preventative coating before shipment.
• Arrangement 8 units come standard with shaft/coupling guards
• Arrangement 9 and 9CB units come standard with belt guards.
• Arrangement 10 units come with weather cover.
• All models are also available in aluminum or all stainless steel construction.

Benefits

• Multiple Wheel Selections: Each size and class are available in multiple widths from 50% to 100%, in 5% increments, to deliver the exact performance you need with a direct driven blower. Complete design flexibility.
• Rugged Construction: Housings are heavy gauge steel and are continuously welded to prevent leakage. Fan bases are 7 and 10-gauge steel with internal bracing to prevent pulsation at all conditions. Less field problems.
• Rotatable Housings: Most models have housings that can be rotated in 45° increments in the field. Allows for field conversion without replacing the blower.
• Ease of Maintenance: Replacing a wheel, motor, or shaft and bearings on belt driven models, is easily accomplished without disturbing the inlet and/or discharge connections. Minimizes extended downtime.
• Quality Components: All belt driven models have self-aligning, cast iron, grease lubricated, pillow block bearings sized for a minimum 150,000 hours average life. All fan shafts are turned, ground, and polished and are coated with a high-quality rust preventative before shipment. Long dependable service.
