3-Panels Ventilation Door

The design and appearance integrated both anti-mosquito and anti-theft. With the difference indoor and outdoor air pressure, temperature and wind pressure, air circulation are formed naturally. The ventilation panels runs with steel cable, which reduces the opening force and noise when in use. The door is assembled in compound method, allowing the structure to be more stronger, firm and deform proof. The U-shaped steel cable is hidden, and prevented from being damaged. The ventilation area stands 2/3 of the entire door.
