Efficient, extra air inlet for very hot periods
Inlets close tightly – no draught or false air intake
Fully insulated – no condensation or ice formation
Operated by a pull rod – all inlets maintain the adjusted opening degree
Maintenance-free and long durability
The frame and fan blade are made of PVC plastic steel, and the deflector is made of high-quality ABS engineering plastic, which is UV resistant, antiaging, cold resistant, thermal insulation and durable.
The arc-shaped large plate fan blades can be adjusted to any open state, allowing for free adjustment of air volume, resulting in better performance.
Specially added high-quality insulation layer, both opening and closing can achieve the best state. If insulation is needed, it can effectively prevent heat dissipation and achieve a tighter sealing effect.
Top mounted, can be automatically controlled or manually controlled.
