Vertical Air Solutions
In-Rack Airflow System
The Next Generation of Airflow Systems Has Arrived

Vertical Air Solutions’ patented In-Rack Airflow System provides canopies with uniform, top-down airflow while homogenizing the climate in a multi-layered rolling rack platform. The first purpose-built air circulation system of its kind, developed by growers for growers. Designed to deliver the airflow your plants need to thrive while saving valuable space in vertical farming applications.

The next generation of airflow systems by VAS has arrived. Every component has been fully redesigned and optimized to deliver the highest air velocities possible while maintaining consistent performance across varying row lengths. New materials and construction methods were carefully chosen to simplify installation and reduce costs without sacrificing quality. Highly modular with multiple configurations, this system was designed to meet the airflow needs of your crop.

Effective and consistent airflow is a must for any successful vertical farm. Fixed or oscillating fans provide uneven air movement and require complicated electrical sourcing. The VAS In-Rack Air Circulation System allows for consistent airflow, and its unobtrusive design disappears alongside the grow lights under the upper rack.



    • EC Inline Fans: Reduces power consumption and allows for granular adjustment of air velocity. EC fans may be eligible for Utility Rebates depending on region and provider.
    • Fan Mounting Options: System can be installed with the fans facing up or down. Mounting brackets allow for precise mounting height and adjustment of duct spacing.
    • Dual Lofted Plenum Design: Maximizes fan performance and reduces turbulence within the ducts.
    • Corrugated Polypropylene Ducts: Humidity-resistant and compatible with common cleaning chemicals but cost-effective enough to replace if desired.
    • Optimized Duct Dimensions: Greatly increases flow rates and duct velocities while minimizing turbulence and friction losses.
    • Pressure Balanced: Provides equal flow front-to-back and side-to-side at variable row lengths and improves exit angle.
    • Air Outlets: Improved circular hole pattern for maximum air dispersion, throw distance, and air velocity.
    • Thin Form Factor: Thinnest form factor on the market reducing overall system height and saving space.
    • Automated Control (Optional): Easily integrate fan controls into common automation platforms for external control of fan speeds.
    • Pop-Up Duct: Lightweight, ships flat, and pop-up design for easy installation.
