Rion Automatic Louver Window Opener for Palram - Canopia and Rion Greenhouses

The Automatic Louver Vent Opener was designed to automatically control the temperature and provide additional ventilation in all Palram - Canopia and Rion Greenhouses.  As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of air flow into the greenhouse and closes when the optimal temperature is reached.  The vent arm was designed with the use of natural minerals that expand with heat to push a piston, which raises the window, as the air gets warmer then contracts as it cools, closing with the use of a spring.  The Automatic Vent Opener operates without the use of electricity.   Feature: Opens roof vent window automatically around 68°F for air circulation, closes when temperature cools Durable metal design with natural wax Smart-Lock connectors make installation quick and easy Works with Palram - Canopias Nature Series (Mythos, Hybrid, Essence), Americana and Rion greenhouses 1 Year Limited Warranty Requires a Side Louver Window   Specifications: Model: HG1033Limited Warranty: 1 yearsLength (in): 15.7Width (in): 2.7Height (in, peak): 2Total Product Weight: 5.5Frame Material: AluminumFrame Color: SilverShip Method: Small ParcelTotal Box Qty (Calculated): 1Box 1 Qty: 1Box 1 Part No: HG1033Box 1 UPC: 763552429674Box 1 Name/Desc: Complete KitBox 1 Length: 11.2Box 1 Width: 3Box 1 Height: 2Box 1 Weight: 5.5Box - Bundle Length: 11Box - Bundle Width: 3Box - Bundle Height: 2Box - Bundle Weight: 2SHIPPING FROM CITY, STATE, ZIP: Bloomington, MN 55431COUNTRY OF ORIGIN: IsraelASSEMBLY REQUIRED: YMINIMUM SHIPPING LEADTIME (DAYS): 2MAXIMUM SHIPPING LEADTIME (DAYS): 4 Owner's Manual
