Ducted Fume Cupboard From China

Ducted Fume Cupboards' Introduction

Many fume cupboards are ducted. There are many different types of fume hoods. In most designs, heated or cooled air is transported from the laboratory area to a fume hood and then vented through ducts to the atmosphere.

A fume hood is only one part of laboratory ventilation. Because recirculation of laboratory air to other areas is not permitted, air handling units serving non-laboratory areas are separated from laboratory areas. To improve indoor air quality, some laboratories also use single-pass ventilating systems, in which hot or cold air is applied only once before exhausting. Many laboratories continue to use return air systems in the laboratory to reduce energy and operating costs, while still providing adequate ventilation for the approved work area. Fume cupboard help remove dangerous levels of pollution.

To reduce the cost of laboratory ventilation, a variable ventilation system (VAV) is used, which reduces the amount of exhaust air when the fume hood sash is closed. These are usually equipped with a locking device, which locks the fume hood when the user leaves the face of the fume hood. The result is that the hoods work slowly while no one is working against them.
