The BDB series is DIDW centrifugal fans with high efficiency non-overloading backward curved impellers. The fans are suitable for supply or exhaust applications in commercial, process and industrial HVAC systems. Sizes of this series is in accordance with AMCA Standard 99-16.     

The operating limit of different fan types of the BDB series is set according to the requirement of Class 1, 11 and 111 limit as defined in AMCA Standard 99-16.

The full BDB series is AMCA certified to Air, Sound and FEG.

The BDB series is available in type S, C, T, X or Z.

The typical selection range of a BC wheel is approximately 40-85% wide open airflow. The maximum static efficiency is from approximately 65 to 75% and occurs at approximately 50% of wide-open airflow.

Generally, BC fan operates at higher speed and used for moving large volumes of air in high static-pressure applications. Due to this purpose, it is robustly constructed.

The advantage of a BC fan is higher efficiency and non-overloading power curve.  

Quick Facts

•  Size from 315 to 1400 mm

   (Size 1600 to 2000 mm available upon request)

•  Capacities to 680,000 m3/h

•  Total pressure up to 4500 Pa

•  High efficiency and low noise

Application

For supply or exhaust application in commercial, institutions and industrial HVAC systems.

Testing

Both air and sound performance ratings are test in accordance to AMCA210 and AMCA300 Standards. All wheels are statically and dynamically balanced to ISO1940 and AMCA204 - G2.5 Standards.

Casing Drain

This option is available when fans are exposed to the atmosphere or operating in high humidity condition.

Outlet Flanges

Outlet flanges are available upon request.

Inspection Doors

The inspection door is supplied in one of the three positions (P3, P4, P5). Please refer to BDB product catalogue, page 4 for the exact location.

Guards

Inlet guards, discharge guards and non-drive end shaft guards are available on request.

Wheel

The wheel of BDB is made of hot rolled sheet steel backward curved blades with polyester coating finish.

Housing

Except for 1250 and above, the housing is manufactured in galvanised sheet steel with the housing fixed to the side plates in "pittsburgh lock" form system.

Housings for 1250 and 2000 are manufactured in mild steel finished with polyester powder coating finish.

Fully welded steel plate housings with painted finish are available for all sizes upon request.

Frame

The frame is manufactured with galvanized angular bars for type "C". For type "T" and "X", it's manufactured with sections of steel with polyester powder coating finish. 

Shaft

Shafts are manufactured from C45 carbon steel. All shafts are coated with an anti-corrosion varnish after assembly.

Bearings

Bearings used are either deep groove ball bearing type with an adaptor sleeve or spherical roller bearings type sealed at both sides for different duty application as defined in ADA Product Catalogue page 4.
