Will the silent cabin be stuffy during use? How effective is the ventilation system?

A: It won't be stuffy. We have developed a silent ventilation system (noise ≤30dB) for confined scenarios, and the conventional model is equipped with 2 in and 1 out ventilation ducts, with an air change rate of 8-12 times per hour, which can maintain air circulation in the cabin; At the same time, it supports the installation of constant temperature air conditioning interfaces, adapting to air conditioners below 1 horsepower to meet different temperature needs, and the satisfaction rate of ventilation effect in 16 years of customer feedback has reached more than 98%.
