MCW type natural ventilator is a series of products in the national standard atlas 11CJ33 "Daylighting Natural Ventilator". MCW type natural vent is a kind of natural exhaust device that uses the heat pressure and wind effect formed by the temperature difference between indoor and outdoor to achieve ventilation effect. It has the characteristics of light weight, beautiful appearance, easy installation, no maintenance, no vibration, low power consumption, etc., The product has a wide range of surface colors to meet user's different needs. MCW type smoke vent is widely used for the ventilation of industrial plants in electric power, metallurgy, chemical, petroleum, machinery and other industries.

MCW type natural ventilator is divided into two types: opening type and opening and closing type:

1. The opening natural vent is composed of a peripheral guard plate, a frame, a rain baffle (a deflector), a gutter, a sink, a flashing plate, and a connecting plate. The open-type MCW low-profile ventilator can exhaust air continuously for 24 hours, and its adoption rate in southern my country is relatively high.

2. The opening and closing MCW roof vents is composed of a peripheral guard plate, a frame, a rain baffle (a deflector), an actuator, a gutter, a downpipe, a valve plate, a transmission mechanism, a flooding plate and a connecting plate. Compared with the opening type, the opening and closing MCW natural ventilation system has more electric valve plate configuration. The electric valve plate controls the opening and closing of the ventilation skylight. The ventilation flow is well controlled and

performance is improved. At the same time, it has the function of heat preservation, smooth drainage, and no rainwater leakage prevention.
