Description
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.
CT Greenhouse is a family-owned greenhouse supplier with hands-on experience speccing ventilation systems for structures of every size. Whether you're automating a single high tunnel or outfitting a multi-bay commercial greenhouse, our team can help you match the right motor, controller, and rack and pinion hardware to your project.
The low voltage ridge vent motor gives you fully automated ridge vent control at a safe 24V DC. This rack and pinion vent motor mounts centrally on your greenhouse ridge and drives vents open and closed through dual output shafts, so both sides of the vent move together in perfect sync. It's the go-to choice for commercial greenhouses, high tunnels, and multi-bay operations where reliable, hands-free ventilation makes a real difference in crop quality.
Manufactured by Advancing Alternatives, the LVM series pairs with any standard low voltage controller or the AegisTEC touchscreen controller for temperature-based automation. Two models are available: the LVM100 for vent runs up to 144 ft, and the LVM180 for longer runs. Both include adjustable limit switches, 1.6" drive shaft adapters, and a weather-resistant housing built for greenhouse environments.

CT Greenhouse expert review
"We've installed hundreds of these motors on everything from 30-foot high tunnels to 200-foot commercial greenhouses. The dual output design is what really sets them apart: one motor drives both sides of the vent evenly, so you don't get the racking and binding issues you'll see with single-sided setups. Pro tip: Pair this with a controller and you'll have temperature-based automation that practically runs your ventilation for you. If you're building with NRCS funding, this motor fits right into the approved ventilation specs."
Common uses
This greenhouse ridge vent motor works with any standard 24V controller system. It's fully compatible with our low voltage controllers and the AegisTEC touchscreen controller for complete automation.
- Commercial greenhouses: Automate ridge vents across single or multi-bay structures for consistent airflow
- High tunnels: Works great on NRCS-approved high tunnel builds with rack and pinion vent systems
- Multi-bay operations: Dual output shafts let one motor handle both sides of a ridge, reducing hardware and wiring
- Retrofit projects: Drop-in replacement for most existing 24V vent drive setups with standard roll-bar mounting
Key benefits
- Safe 24V operation: Low voltage means no electrician required for installation in most areas, and it's inherently safer in wet greenhouse environments
- Balanced dual output: Both output shafts drive simultaneously, keeping your vent aligned and reducing wear on the rack and pinion hardware
- Universal controller compatibility: Works with any 24V DC controller, including the AegisTEC system and standard relay-based setups
- Adjustable limit switches: Set your exact open and close positions to match your vent travel, preventing over-extension and binding
- Weather-resistant build: Designed for the humidity, dust, and temperature swings you'll find inside a working greenhouse

Frequently asked questions
Q: How does a greenhouse ridge vent motor work?
A: The motor turns a drive shaft connected to rack and pinion hardware along your ridge. When the controller signals to open, the motor rotates the shaft, which pushes the vent panels up. Reversing polarity closes them back down.
Q: What size ridge vent motor do I need for my greenhouse?
A: For vent runs up to 144 feet, the LVM100 handles it. For longer runs or heavier vent assemblies on commercial structures, go with the LVM180.
Q: Can I use a low voltage vent motor with my existing greenhouse controller?
A: Yes. This motor works with any 24V DC controller, including relay-based systems and the AegisTEC touchscreen controller. You may need a controller interface box if you're connecting to a multi-zone setup.
Q: What's the difference between 24V and 110V greenhouse vent motors?
A: A 24V motor is safer in wet greenhouse environments and typically doesn't require a licensed electrician to install. 110V motors deliver more raw power but need hardwired circuits and carry higher shock risk around water and humidity.
Q: How do I install a rack and pinion ridge vent motor?
A: Mount the motor centrally on your ridge, connect the drive shafts to your rack and pinion arms, wire it to your controller, and set the limit switches to match your vent's open and close travel. A drip loop on the wiring keeps moisture out of the motor housing.
