24" Intake Shutter Vent for Riga XL Greenhouses

The 24" Intake Shutter Vent is a high-capacity motorized intake vent engineered for the largest Riga greenhouse structures. Built for the Riga XL series, it automatically opens to draw in the high volume of fresh air these large greenhouses demand, and closes to block insects and debris when the exhaust fan is off.

Key Features

• Precise fit: Requires a 24.25" × 24.25" rough opening — sized for Riga XL wall panels
• Optimal placement: Install high in the lowest front-wall panel, directly opposite the exhaust fan, for maximum cross-ventilation across the full length of the greenhouse
• Plug-and-play installation: Pre-wired with a 9-foot power cord — no hardwiring or electrician required
• Motorized shutters: Automatically open for airflow and close when idle to block pests and debris
• High-capacity airflow: The largest intake vent in the Riga ventilation lineup, matched to the air volume requirements of XL-sized structures
