Univent Automatic Window Opener by J. Orbesen Teknik Aps
Does your coop or greenhouse need extra ventilation due to hot stuffy conditions in the spring, summer and fall? Univent, the Automatic Window Opener can solve that problem.
Our special patented heat sensitive (due to solar gain or sun heat) thermo-regulated paraffin wax hydraulic lift system transforms any window or skylight up to 15 pounds into an automatic window or vent opening.
Easy to install, as long as the window is less than 15 pounds and swings on a hinge, or easily insert, install or build a new window or vent, this venting hinge will open your coop or greenhouse window with a variable temperature setting on the opener.
Made by J. Orbesen Teknik out Denmark, who invented the compact paraffin wax thermo-regulated hydraulic cylinder and venting openers. This is still the highest quality automatic (solar) window vent opener on the market today due to its long lasting durable and replaceable parts.
Cylinder is warranted for 3 years!
Spare parts available by request.
Opening force: 15 Pounds
Temperature opening range (adjustable): 66-77 degrees F
