As an important ventilation device, low-profile ventilator is often installed on the roofs of steel structure industrial plants such as metal metallurgy, energy and power, automobile manufacturing, etc., and can be used for new plants and renovation of old plants. Today, the editor of Mcwell will introduce the advantages and application scope of structural natural ventilator.

Taking the National Standard Atlas 11CJ33 "Ventilation and Daylighting Skylight" as an example, low-profile ventilator can be divided into two categories: parallel air duct type natural ventilators and thin ventilators (interval air duct type) according to their own structure. Both have the advantages of low dead weight load, reduced roof steel consumption, and high cost performance.

Coastal areas with multiple typhoons

As we all know, roof smoke vent has low height and good wind resistance, and can be used in coastal areas with multiple typhoons.

High heat and high corrosion workshop

The resistance coefficient of the parallel air duct type natural ventilator is about 3.8, which is only 1/4 of the general thin ventilator. Its ventilation efficiency is high and the effective ventilation area is large. It can be widely used in high-heat workshops.

Roof louver vents can also be installed on the roof of high-corrosion industrial plants. The frame can be processed and formed by galvanized steel, aluminum alloy and stainless steel according to the anti-corrosion requirements of the workshop and the wind and snow load of the project site.

Strictly prevent water leakage workshop

Some workshops where precision instruments or production equipment are installed have particularly high requirements for the waterproof performance of the ventilators, requiring zero water leakage hazards. Parallel duct smoke vent rooflight is ideal for this type of workshop. It has a three-layer rainproof board, no matter the rainwater enters the ventilator from any angle, the rainwater can only hit the first and second rainproof boards, and the third rainproof board can bear splashing rain and rain fog. Rainproof performance is much better than general thin ventilators. It adopts the patented technology of full-structure waterproof, which fundamentally eliminates the hidden danger of leakage.

As the editor-in-chief and participating unit of the national standard atlas, McWay has rich experience in the design, production and installation of thin roof ventilators, and can provide system customized services according to customer requirements.
