IDB-X Series Forward Curved Inline Duct Blowers

Applications:

An Inline make-up air solution for cases where a rooftop curb mounted solution is not available.
As an air moving module for systems built up with other components such as heating/cooling coils.
Noise sensitive areas - the low rpm forward curved wheel typically radiates less vibration than higher rpm backward inclined wheel solutions.
When the application requires an air mover in a duct system located in a ceiling space.
Redistribution or recirculation of air in a work space.
Interlocked with entry doors to prevent entry of cold outdoor air into retail sales space and thus greets customers with warmth.
Bathroom/ rest room exhaust - one duct blower serving multiple intakes.

Features:

Wheel Diameters: 7” through 15”.
CFM: Approximately 500 to 5700 CFM in a single blower.
Constructed from galvanized steel for durability.
Forward Curved blowers operate at low RPM for low noise levels.
Heavy duty ball bearings suitable for -65º F to +250º F.
Keywayed shafts both ends for clockwise or counter clockwise rotation.
Saddle type motor mounting platform provides extended belt tension adjustment range on all IDB models.
Delhi blowers will not “surge”, “hunt” or “stall”.
Optional variable pitch motor pulley permits field adjustment (typically + or - 15%) to match air delivery needs.
Quiet forward curved blowers operate at 1/2 the rpm of other inline solutions.
IDB-X models offer external mounted motors & drives for easy access, however they are not ETL or AMCA certified at this time.
