Description
Key Features
Powerfoil X4
Powerfoil X4 solves real problems in real workplaces. It moves an incredible amount of air — enough to make people in large, open spaces feel noticeably cooler and more comfortable. Your team stays focused, your equipment stays cooler, and your facility becomes a better place to work.
IP56 Rated
Dust, debris, high-pressure water jets — Powerfoil X4 shrugs them all off. Built exactly for warehouses, factories, and heavy-duty industrial spaces.
Feel 10° Cooler
Patented airfoil technology delivers smooth, consistent airflow that makes people feel 10 degrees cooler — without touching the thermostat.
Under 55 dBA
The quietest gear-driven fan in its class. Industrial torque, smooth airflow — without the noise or turbulence you'd expect from a fan this powerful.
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 sealed 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. Powerfoil X4 doesn't.
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, on-site replacement with just four screws — no costly shutdowns, no heavy equipment, no complicated teardown. Minimal disruption. Lower long-term maintenance costs. Keep your facility running.
