200 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.
• Industries Served: Commercial HVAC, Ventilation, Heating, Cooling, Construction.

Features:

• Wheel Diameters: 7” through 20”.
• CFM: Approximately 500 to 12,500 CFM in a single blower (twins available).
• Static Pressure: Usage to about 3” static pressure is common, although allowable range is higher.
• Constructed from cold rolled steel, with green baked on powder coat. The outdoor unit uses protective galvaneal steel under the powder coat.
• 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 models.
• As part of an HVAC system Delhi Duct Blowers will not “surge”, “hunt”, or “stall”.
• The variable pitch motor pulley permits field adjustment (typically + or - 15%) to match air delivery needs.
• For the quietest operational needs we offer optional internal spring isolation of the blower/motor from the housing thus greatly reducing radiated cabinet noise.
• Twin units (two duct blowers on a common shaft) offer a wide but not tall solution for situations where vertical space is limited.
• Quiet forward curved blowers operate at ½ the rpm of other inline solutions.
• An outdoor series, 9200, is available.
