The large steel structure workshop uses the positive and negative difference of the atmospheric pressure outside the workshop to exhaust the waste heat, smoke, dust and exhaust gas generated by the production activities in the workshop, and inhale fresh air to achieve the purpose of ventilation and exhaust gas. The application range of Mcwell smoke ventilation: metallurgy, manufacturing, chemical industry, electric power, industrial plants,  shipbuilding, machinery and other industrial buildings.

1. Low-profile ventilator

The low-profile ventilator is equipped with four-layer rainproof board, which increases the rainproof effect. The thin ventilation skylight of the steel structure factory building also has light weight, low height and resistance. Good wind performance, suitable for steel structure workshops in coastal cities, rainy areas in the south, and large wind coefficients.

2. Streamlined ridge ventilator

The ridge ventilator has a arched structure, with ventilation volume. It adopts hidden button self-tapping nails to avoid water leakage caused by direct drilling on the rain plate and the deflector, and is suitable for ventilation. 

3. Smoke vent skylights

The triangular smoke vent skylights is triangle in appearance. The upper-opening roof fire vents has large ventilation capacity, and the downward-opening triangular smoke ventilator has good rainproof performance, which fully meets the ventilation and smoke demand of the steel structure factory building.

4. Linear natural vent
