Your Woods Air Movement Authorized Manufacturer’s Representative
Woods Air Movement has been engineering industrial axial fans since 1909, including the first aerofoil-bladed axial fan in the world. ChopAir is an authorized Woods Air Movement manufacturer’s representative providing turnkey service for commercial and industrial HVAC projects: design and engineering, equipment spec and selection, supply and delivery, and support through project completion.
EC Induction Thrust Fan
The Woods Air Lineup
Three fan categories for commercial & industrial applications
Every Woods Air fan ChopAir carries falls into one of three categories. Each solves a different air movement problem, and many projects use more than one. ChopAir helps you match the category, the model, and the configuration to your building.
Axial Fans
The ducted workhorses of industrial ventilation. Woods axial fans use high-pressure die-cast aluminum impellers, X-ray inspected for integrity, with blade pitch angles that can be adjusted in the field for performance flexibility. Installed across the US in tunnels, power plants, and commercial buildings.
Models Carried
JM Tube Axial JMv Aerofoil JM 2-Stage JMTS Reversible EC-JMS
Jet Fans
Duct-free ventilation by thrust. Strategically placed jet fans move and dilute contaminated air across enclosed spaces such as parking garages and tunnels, with sensors telling the control system which fans to run. The result: lower construction cost, more usable ceiling height, and ventilation that responds to real conditions.
Models Carried
Induction Thrust Fan JTv Slim-Line EC Induction Thrust
Plate Fans
Wall-mounted exhaust and supply, the simplest and most common form of axial fan. An impeller and motor fixed to a plate, installed on a wall to exhaust hot air, fumes, and particles, or to supply fresh air. Woods’ EC plate fans add speed control and significant energy savings over traditional AC designs.

Commercial Fan Selection Software
Industry-leading fan selection software — backed by Samsung
Woods Air Movement is part of Fläkt Group, a global HVAC engineering company owned by Samsung. That global infrastructure shows up in the tools available to specifiers: the Woods Air fan selection software is among the most capable in the commercial HVAC industry, letting you define your space, airflow requirements, and performance parameters to identify the right fan and configuration before you ever place an order. As your authorized manufacturer’s representative, ChopAir can walk you through the tool, help you interpret results, and turn your output into a spec-ready equipment package.
Heads Up: Jet Fan Performance Is Rated in Newtons, Not CFM
If you’re used to selecting fans in CFM (cubic feet per minute), the Woods Air selection tool will throw you off at first — jet fan performance is rated in Newtons (N), a unit of thrust force. This isn’t a Woods Air quirk: it’s an industry-wide standard for thrust-based fans. The US market is largely used to CFM; the rest of the world, and virtually all fan manufacturers, rate jet fan thrust in Newtons. Jet fans work by force, not duct flow — they push air across an open space rather than moving it through a duct — so Newton is the physically correct unit. You’ll get used to it. In the meantime, the reference below will help.
Show Newton conversion reference & how to read the software output ▼
| Newton (N) | Pound-Force (lbf) | Typical Context |
|---|---|---|
| 1 N | 0.225 lbf | Unit reference (1 N = 0.225 lbf) |
| 100 N | 22.5 lbf | Small jet fan output |
| 300 N | 67 lbf | Typical parking garage jet fan |
| 500 N | 112 lbf | Larger garage or shorter tunnel run |
| 1,000 N | 225 lbf | Heavy-duty road or rail tunnel application |
Why you can’t just convert Newtons to CFM: Newtons measure thrust force, not air volume. A jet fan rated at 500 N doesn’t move 500 N of air through a duct — it exerts 500 N of force that induces a much larger volume of air movement across the garage or tunnel space. Converting between the two requires knowing the fan’s discharge velocity and the induction ratio for your specific space geometry. The selection software handles all of this automatically: input your space dimensions, ceiling height, required air changes, and occupancy type, and it outputs the fan count and Newton rating you need. Don’t try to back-calculate Newtons to CFM by hand. Use the tool, then reach out to ChopAir if you want help interpreting the output.

Where Woods Air Is Specified
Built for industrial & commercial environments
Woods Air fans protect health and life in day-to-day pollution control and demanding industrial environments. Here are the application categories ChopAir clients work with most.
Parking Garages
Duct-free jet fan systems that dilute and extract vehicle exhaust across enclosed and underground garages. Sensor-driven control means fans run when conditions call for it, cutting energy use.
Road & Rail Tunnels
Longitudinal ventilation and emergency airflow control for tunnel infrastructure, including reversible fans that can push air in either direction during an incident.
Industrial & Manufacturing
General ventilation, fume and heat exhaust, and process cooling for factories, plants, and warehouses. Plate fans handle wall exhaust while ducted axials serve central systems.
Commercial Buildings
Ducted supply and exhaust for offices, mixed-use developments, and institutional buildings, with energy-efficient options for new specs and retrofits alike.
Smoke Control & Life Safety
Woods builds high-temperature fan variants designed for emergency smoke extract duty, a core part of the company’s life safety heritage. ChopAir can help you evaluate options against your project’s code requirements.
Power, Data & OEM Equipment
Cooling airflow for power plants, data centers, generator sets, chillers, and air handling units, including compact EC fans designed specifically for OEM integration.

Controls & Integration
A fan is only as smart as its controls
Modern fan systems earn their keep when they respond to real building conditions. ChopAir helps integrate Woods Air fans into your building management system, so ventilation runs on data instead of guesswork. This matters most for jet fan systems, which are sensor-driven by design, and for EC models with speed control built in.
Demand-Controlled Ventilation
Gas and occupancy sensors tell the BMS when air quality thresholds are crossed, and fans ramp up only when needed. In parking garages this is one of the fastest payback investments in building infrastructure.
EC Speed Control
Woods’ EC models accept speed commands directly from the building network, with no external inverters required. The BMS can trim airflow to match the load throughout the day.
Scheduling & Sequencing
Run fans on occupancy schedules, stage multiple units across zones, and coordinate ventilation with the rest of your mechanical plant from one front end.
Monitoring & Alerts
Track runtime, status, and faults from the BMS so maintenance happens before a failure, not after. Runtime data also supports planned service that extends fan life.
ChopAir also delivers complete turnkey BMS projects for commercial and industrial properties.
