The Low Voltage Ridge Vent Motor is a 24V DC rack and pinion vent motor designed for automated greenhouse ridge vent control. Manufactured by Advancing Alternatives, this low voltage ridge vent motor mounts centrally on your greenhouse ridge and drives vent panels open and closed through dual output shafts, keeping both sides of the vent synchronized for smooth, balanced operation.

Two models for every greenhouse size

The LVM series comes in two configurations to match your structure. The LVM100 handles vent runs up to 144 feet, making it the right fit for most standard greenhouses and high tunnels. The LVM180 is built for longer runs and heavier vent assemblies on larger commercial structures. Both models feature adjustable limit switches so you can dial in the exact open and close positions for your vent travel.

Why growers choose 24V

A 24V greenhouse vent motor is inherently safer in wet, humid greenhouse environments compared to 110V alternatives. Low voltage operation typically doesn't require a licensed electrician for installation, and it eliminates the shock risk that comes with running line voltage near water and plant material. You get reliable, automatic greenhouse ventilation without the added cost and complexity of hardwired electrical circuits.

Key features

• 24V DC bi-directional operation for safe, reliable vent automation
• Dual output shafts drive both sides of the ridge vent simultaneously
• Adjustable limit switches to set exact open and close travel positions
• 1.6 inch drive shaft adapters included for standard roll-bar compatibility
• Compatible with all major 24V greenhouse controllers, including the AegisTEC touchscreen system
• Weather-resistant housing built for greenhouse humidity and temperature swings

Built for commercial operations and NRCS projects

This greenhouse ridge vent motor is designed for the demands of commercial growing operations, multi-bay greenhouses, and high tunnel facilities. It's typically eligible for NRCS high tunnel program builds, making it a strong choice for growers working with EQIP funding. The dual output vent motor design reduces hardware and wiring compared to single-sided setups, and universal controller compatibility means it drops into virtually any existing 24V automation system.
