Product Introduction
The frame is made of high-quality ABS engineering plastic, and the side and flip plates are made of PVC plastic steel, which is UV resistant, anti-aging and durable.
The new design ensures a better user experience with double door opening at the same time, which can be adjusted for opening or closing as the air volume might be needed.
The high-quality insulation layer is especially added, which can keep the best state at opening and closing; if insulation is needed, it can effectively prevent the heat emission. Its insulation effect is better when it is sealed tightly.
It can be controlled automatically or manually.
It is suitable for workshops, greenhouses and large-scale livestock breeding places.
