Natural Ventilation System

throat size is over 1.5mm is called large throat natural vent, which the frame is welded with profiles. and small throat natural ventilator.
The natural ventilation system which throat size is less 1.5mm is called small throat natural vent, which is integrally pressed with hot-dip galvanized steel, without the
need for a welding base, and can be directly installed on the roof purlin.

Because machinery manufacturing workshops require more air changes. And natural ventilation system has a wide space, large air intake and high ventilation efficiency.
So it is suitable for high-temperature and high-heat manufacturing workshops.

Advantages:

1. Adopt the patented technology of “holistic waterproof structure”, no leakage hazard.

2. The skeleton adopts hot-dip galvanized steel sheet integral hydraulic forming, with good stability and good anti-corrosion performance.
