IDL Series Low Profile Inline Duct Blowers

• Use as part of an HVAC system.
• Durable galvanized steel construction.
• Delhi forward curved blowers will not 'surge', 'hunt' or 'stall'.
• Ideal for indoor applications.
• Optional variable pitch motor pulley permits field adjustment (typically + or - 15%) to match air delivery needs.
• Quiet forward curved blowers typically operate at 1/2 the rpm of other inline solutions.
• Low profile design for use in bulkheads or other areas with reduced clearance.
• Easy to use drop down access panel provides quick access to blower and motor.

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 workspace.
• 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. 
• Ideal for use in bulkheads and other areas with low clearance.

Features:

• Wheel Diameters: 7” through 15”.
• CFM: Approximately 500 to 5700 CFM in a single blower.
• 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 IDL models.
