Nothing Moves Air Like This.
Patented airfoil technology and a maintenance-free NitroSeal™ gearbox — Powerfoil X4 sets the standard everything else gets measured against.
Key Features
IP56 Rated
Dust, debris, high-pressure water jets — Powerfoil X4 shrugs them all off.
Feel 10° Cooler
Patented airfoil technology delivers smooth, consistent airflow that makes people feel 10 degrees cooler.
Under 55 dBA
The quietest gear-driven fan in its class.
Up to 15% More Productive
Cooler, more comfortable people work better. Powerfoil X4 helps increase worker retention and deliver up to 15% more productivity.
The Gear-Driven Advantage
Powerfoil X4 uses a NitroSeal™ gearbox — perfect for facilities where torque and durability matter most. Pressurized with nitrogen gas, it requires no oil changes, no oil degradation, and no contamination — ever. Maintenance-free by design, with less than 1% failure rate.
- More torque, more airflow across large industrial spaces
- Under 55 dBA — industrial power without the noise penalty
- Consistent, stable performance day after day in high-demand environments
Patented Airfoil Technology
Powerfoil X4's performance starts with its uniquely engineered airfoils. Inspired by airplane wing technology, each blade is shaped with a precise angle of attack to generate massive airflow with exceptional efficiency. Three patented features work together to deliver stronger, more focused airflow exactly where it's needed.
- Airfoil — Aerodynamic profile modeled after aircraft wings to move extreme volumes of air with minimal energy use
- Airfence® — Redirects airflow down into the occupied zone instead of letting it spill off the tips
- Winglet — Cuts cleanly through the air to reduce drag and boost overall efficiency
Safety You Can Trust
Big Ass Fans pioneered the HVLS fan in environments with people by creating the safest fans in the market. Our patented safety features are developed to eliminate the failure points that can result from adjustable extension tubes, snap-in blades, and smaller hubs — the weak spots other fans live with.
Because Downtime Costs Money
In the unlikely event your Powerfoil X4 motor ever needs replacing, you won’t have to dismantle the entire fan. The offset motor is designed for simple replacement with just four screws — no costly shutdowns, no complicated teardown, no unnecessary disruption to your operation.
