Low Pressure Centrifugal Inch Blowers
Forward Curved Low Pressure Blowers for Industrial Cooling
Available to buy online, the BD range of double inlet low pressure centrifugal fans, commonly known as inch blowers, feature a forward curved turbine powered by an external rotor motor. They are designed for a wide range of low air pressure applications. With motors situated within the width of the impeller and fan housing this makes for a compact unit. As the scroll housings of single inlet fans are in fabricated steel, detachable discharge flanges enhance the mounting possibilities of this versatile and popular range.
Inch Blowers: Nominally Dimensioned by Diameter and Length
Our low pressure forward curved double inlet centrifugal fans known in the industry as inch blowers are available in a range of sizes: BD-7/7 means the diameter is 7” and the long impeller is 7” wide too.
The standard IP20 level of ingress protection is offered on most AC compact axial fans with specialist IP55 and high temperature versions are available on variable lead times.
1~ fans are speed controllable by voltage variation, and can be supplied with 3 speed tapped winding.
3~ fans are speed controllable using a frequency speed controller.
To prevent electromagnetic vibration transmitting to the unit frame, anti-vibration mounts are fitted at the motor pad on the side plate and on the foot corners.
Electronically Commutated EC product lines are available on request if applications require a more energy efficient product.
The Forward Curved Fans We all Know As Inch Blowers
Versatile, Cost Effective & Available from Stock
The standard IP20 level of ingress protection is offered on most AC compact axial fans with specialist IP55 and high temperature versions available on variable lead times. Ball bearings are the dominant support system enabling a lifetime span of up to 40,000 hours, but for those looking for a value cost effective range, some models are available with sleeve bearings. Other additional options include bi-directional flow, steel impellers and special voltages.
Contact us to discuss lead time and availability on components required for specific applications or those required for more arduous scenarios.

EC Motors, the Logical Choice in Reducing Power Consumption, Costs and Environmental Impact
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. Most air conditioning units for example are being refurbished using EC backward curved fans (or plug fans). However, EC inch blowers can be used to simplify a refurbishment programme, as they will fit directly into existing units, thanks to their industry standard sizes and fixing points.
Resourceful & Solution Led Thinking
AC v's EC
It's EC to See the Savings
The gain in efficiency can be easily demonstrated by comparing two models; one in AC the other in EC. Comparing the BD10/10.M4.0,59Kwa (AC) and the BD10/10.M4.EEC80 (EC) installed in a unit with an operating point of 2500m³/h at 400Pae protection principle ensures that an ignition source cannot arise
