Palram Auto Vent Opener
Palram Auto Vent Opener keeps your Palram greenhouse at the optimum temperature. The vent arm contains a special oil that expands as the temperature increases. As temperature reaches the upper 60s, the roof vent is lifted to allow the interior to cool off. When the temperature goes back down, the oil contracts and the vent is closed.
