Industrial Centrifugal Fans & Blowers

Your air treatment system is only as reliable as the fan moving air through it.

Mismatched fans mean inadequate ventilation, excessive energy costs, and premature failure. Viron engineers fans and blowers as part of your complete system, sized for your actual CFM, static pressure, and air chemistry, then built from materials that withstand corrosive environments for decades.

Purpose-Built for Industrial Ventilation

You need industrial ventilation blowers matched to your air stream—whether moving clean air or handling corrosive, particulate-laden exhaust. 

Choose the design that solves your challenge:

VCB centrifugal fan
VCF/VCB Centrifugal Fans

Workhorse for industrial exhaust. VCB-1100 Series delivers 400-100,000 CFM across 20 sizes (12"-80" wheels) in PVC, PP, or FRP. Solid fiberglass backward incline wheels offer highest efficiency and quietest operation—lower energy costs, reduced noise. AMCA certified performance. Powder-coated steel bases resist corrosion.

vif inline fan
VIF Inline Centrifugal Fans

Space-saving straight-through design with centrifugal power. Delivers 1,200-100,000 CFM across 17 sizes (12"-60" wheels) in FRP. Solid fiberglass wheels, corrosion-resistant components, stainless steel hardware. Fits into duct runs without elbows when floor space is limited.

VPB push blower
VRB Radial Blowers

Rugged radial wheel design handles dirty, dusty, or corrosive air that clogs standard fans. Higher CFMs with higher static pressures—435-125,000 CFM across 17 sizes (16"-104" wheels). Solid FRP housing withstands harsh chemicals. Powder-coated steel base provides structural integrity. Dynamically balanced for reliable operation.

Every Viron fan is AMCA certified for performance and built to integrate with your complete air treatment system.

Frequently Asked Questions

What makes an industrial centrifugal fan different from a standard exhaust fan?

Industrial centrifugal fans generate higher static pressure to move air through complete ventilation systems—ductwork, scrubbers, dampers, and stacks. Standard exhaust fans lack the power to overcome system resistance and fail quickly in corrosive environments. Centrifugal designs use backward incline or radial wheels to deliver consistent CFM against static pressure while handling contaminated air streams that would destroy residential or light commercial fans.

How do I know which fan size and type I need for my application?

Fan selection depends on three critical factors: required CFM (air volume), static pressure (system resistance), and air chemistry (contaminants). 

Viron engineers calculate these based on your process equipment, ductwork configuration, and exhaust requirements. A VCF backward incline fan delivers the highest efficiency for clean to moderately dirty air. VRB radial blowers handle heavy particulate or sticky contaminants. Inline VIF fans work when floor space is limited. We size fans as part of your complete system—not as standalone components.

What does AMCA certification mean for industrial fans?

AMCA (Air Movement and Control Association) certification verifies that published performance specs match actual tested performance. When a Viron fan shows 50,000 CFM at 12" static pressure, that's certified performance—not marketing estimates. AMCA testing ensures your fan delivers promised airflow and efficiency, which translates to predictable energy costs and reliable ventilation. Non-certified fans often fail to meet promised specifications, forcing you to oversize equipment or accept inadequate ventilation.

Can I replace just the fan in my existing system, or do I need new ductwork too?

Depends on your current system condition and performance requirements. If existing ductwork is corroded, undersized, or creating excessive static pressure, replacing only the fan won't solve your ventilation problem. 

Viron engineers evaluate your complete system—duct sizing, material compatibility, air velocity, and static pressure losses. We'll tell you if a fan replacement works or if ductwork modifications are needed to achieve proper airflow. Many facilities waste money replacing fans repeatedly when the real problem is poorly designed ductwork.
