Low Pressure Centrifugal Fans | Inch Blower

Inch Blower Design

These forward curved double inlet centrifugal fans are also known as the “Inch Blower” due to their simple impeller design and size eg “BD-7/7”. The BD Fan is a high quality forward curved centrifugal fan featuring a galvanised steel scroll and impeller, dust and hosed water protected to IP55 standard. Anti-vibration mounts are fitted in 3 places, at the motor pad on the side plate and on the foot corners to prevent electromagnetic vibration transmitting to the unit frame. Standard BD fans are speed controllable by voltage variation, and can be supplied with 3 speed tapped winding. Discharge flanges are available upon request. The fans are fitted with rigid motor supports to withstand mechanical handling damage.

Applications

Forward Curved centrifugal fans such as the BD range are commonly used across an array of low pressure applications including air conditioning units, air curtains, heating and cooling coils, air handling units, ventilated workbenches. Visit our applications page for more information.

Product Range Variants

Inch Blowers are typically available in AC voltages, however Electronically Commutated EC product lines are available on request if applications require a more energy efficient product. Energy efficient technology has grown in popularity over recent years, primary due to the significant European Energy Related Products legislation (ERP). So EC fan motors have become the logical choice in reducing power consumption, costs and ultimately the environment. Interested in how switching to Ec product ranges can equate to cost effective savings? In our case study we examine the use of both products in a simple refurbishment project to show the potential energy savings.
