Built for Performance
Our centrifugal upblast fan collection features models engineered for both commercial kitchen applications and general ventilation needs. The centrifugal wheels pull air in and throw it outward, creating higher static pressure than conventional fans, perfect for complex ductwork systems.
Most hood exhaust units feature heavy gauge aluminum construction that prevents grease buildup in the fan wheel, a crucial feature when dealing with grease laden air from a busy vent hood. The motor compartment cools motor components by keeping them completely outside the exhaust air stream, ensuring long motor life even in demanding food service environments.
We offer everything from lightweight spun aluminum models perfect for a food truck to heavy duty industrial exhaust fans that handle fume hood applications in manufacturing settings. Fan motors typically last 7-10 years with basic maintenance, significantly outlasting budget alternatives.
Choosing the Right Size
Wondering about CFM range and base size specifications? Don't worry, we speak fan language fluently.
Selecting the right centrifugal fan comes down to understanding your air volume requirements, exhaust fan motor capabilities, and mounting dimensions. For most restaurant exhaust fans, building codes dictate minimum air movement rates based on cooking equipment. A standard 6-foot cooking line typically requires between 1,200 to 2,500 CFM, while a small storage room might need just 300 CFM.
The trickier aspect is calculating static pressure requirements, which determine how efficiently your fan can move air through hood filters and ductwork. Think of it like choosing between direct-drive fans (simpler, fewer moving parts) and belt-drive fans (better for higher static pressure applications).
Unlike big-box home improvement retailers that sell everything under the sun, we specialize exclusively in centrifugal exhaust fans and other quality ventilation equipment. Just share your specifications, and our team will help identify the perfect high-efficiency solution for your particular application, whether it's kitchen grease exhaust or solid fuels ventilation.
Installation and Compatibility
"Will this centrifugal upblast exhaust fan fit my existing roof curb?" It's a common concern for facility managers everywhere.
Most units mount on a specialized fan base or roof curb, a raised frame that creates a weatherproof seal between your roof surface and the exhaust equipment. If you're upgrading an older system, we can match your existing curb cap dimensions to ensure perfect compatibility without costly modifications.
For new installations, we provide compatible roof curbs designed specifically for your chosen centrifugal roof exhaust fan. Our popular models include a pre-wired disconnect switch and easy access panels for maintenance. Many units feature quick release latches for simple cleaning and inspection of the drive compartment.
Concerned about noise levels? Our direct drive models offer remarkably quiet operation at 65-85 decibels, while high speed direct drive units deliver maximum performance when needed. For applications requiring adjustable airflow, we offer variable speed control options compatible with most fan types.
All our products include manufacturer warranties and backdraft damper accessories where appropriate. As factory-authorized dealers, we ensure every unit arrives with proper documentation for your upcoming inspections, even in high wind installation areas.
Why Shop at Industrial Fans Direct for Centrifugal Upblast Exhaust Fans?
Why trust your restaurant grease ventilation to big-box stores that can't tell the difference between an open drip proof motor and a nominal wheel specification?
For over two decades, we've focused exclusively on becoming experts in centrifugal fan technology and other specialized ventilation equipment. Our customers appreciate dealing with knowledgeable professionals who understand that a kitchen exhaust fan isn't just another appliance, it's a critical component of your building's infrastructure.
Most importantly, we remain available long after your purchase. When your exhaust or supply fans need maintenance or your restaurant hood exhaust system requires upgrading three years down the road, you'll reach actual humans who understand the intricacies of your equipment configuration. Need a replacement part for your centrifugal wheels or advice about upgrading to an energy-efficient model? Our team provides genuine support without transferring you between departments. Isn't that how shopping should always work?
