Greenhouse growers asked, and VES-Artex has responded. The highly demanded 20-inch 119433 and 24-inch 119434 models have become go-to solutions in greenhouse environments where consistent airflow, efficiency and durability are critical.

These models are equipped with EC motor technology, providing growers with improved energy efficiency and consistent airflow output. Performance testing shows the 20-inch fan delivering up to 2,836 CFM, while the 24-inch model reaches 3,327 CFM at 0.0 static pressure. Both models operate at 115V with a 1/4 horsepower motor and are designed to maintain performance across a range of static pressures, giving growers the flexibility to manage changing environmental conditions.

Greenhouse Airflow At The Ready

“We are seeing strong demand for these sizes because they hit the sweet spot for many greenhouse operations,” said Nick LeMay, Ventilation Product Manager for VES-Artex. “Growers need airflow they can rely on day in and day out, and these fans deliver that consistency without adding unnecessary energy costs.”

These models build on the proven performance of the VES-Artex Aluminum Shutter Exhaust Fan line, a cornerstone product in greenhouse ventilation. The VES-Artex shutter exhaust fan is a robust, durable and effective solution designed specifically for greenhouse applications. Built to perform in high-moisture environments, the fans feature corrosion-resistant shutters, a shutter tie bar that reduces unnecessary movement, and a fully enclosed CSA and CSA-US approved motor. Balanced silicon steel rotators reduce noise and vibration, while moisture-resistant rubber gaskets protect the motor seal, switch and wiring connections.

Designed for long-term performance, the bearings are engineered to operate in extreme temperatures ranging from -40°F to 284°F, ensuring reliability across seasonal and environmental swings common in greenhouse operations.

Fit For Your Greenhouse

Available in 12-inch, 16-inch, 20-inch and 24-inch configurations, the Aluminum Shutter fan line offers flexibility across a wide range of greenhouse layouts. Units are available in single-speed or three-speed models and come fully assembled with a pre-wired 9-foot power cord, allowing for simple plug-and-play installation without the need for an electrician. Intake safety grills meet OSHA compliance standards, supporting both performance and safety in working environments.

In greenhouse environments, proper ventilation supports temperature control, humidity regulation, disease prevention and CO2 exchange. By removing excess heat and moisture while maintaining steady air movement, shutter exhaust fans play a critical role in reducing plant stress and creating uniform growing conditions.

VES-Artex supports these systems with a full lineup of airflow solutions, including circulation fans, ceiling fans and high-volume low-speed fans, all designed to work together within an integrated environmental control strategy.

“Our focus is on helping growers create stable, high-performing environments,” LeMay said. “When airflow is consistent, everything else in that system works better.”
