Fume hood is the most common local exhaust equipment in the laboratory, especially in the physical and chemical laboratory, it is an indispensable experimental equipment for laboratory researchers. Laboratory personnel stay in the laboratory for a long time and come into contact with reagents of different concentrations, and these reagents have some hazards and smells accordingly. Indoor ventilation has become a very important safety issue. This is why the laboratory needs to be equipped with professional fume hoods , which is also the original intention of our design. For your safety, we are always on the way.
1. Introduction of fume hood
A fume hood is a work space that is airtight and ventilated at the same time. It is designed to control, dilute and exclude manufactured fumes, aerosols and particulates from this confined space. In most laboratories, the fume hood is the primary control device for protecting laboratory operators from toxic and hazardous chemicals. At the same time, the fume hood can also protect against sudden fires, explosions and chemical splashes at the minimum operating height.
2.How ducted Fume Hoods work？
The general airflow of a fume hood has the air enter from the face of the hood and out through the exhaust collar. An exhaust fan connected to the ducting system pulls air and unwanted substances away from the operator, out of the hood body, and exhausts them to the atmosphere. 
The sash is set at the optimum configuration to maintain the recommended face velocity of 0.3 – 0.5 m/s. The airfoils and the baffles are added features that aid in the airflow. 
3.About us
 In a scientific laboratory environment, good ventilation plays a crucial role in creating a clean laboratory environment, ensuring the scientificity and reliability of the experimental conditions and the safety of the experimental process. FH series fume hood is a new generation of laboratory ventilation equipment designed, developed, developed and produced by our company according to the needs of chemical, biological, pharmaceutical and other laboratories.
Here are some product profiles to help keep your fume hoods working at its optimum performance.

Difference:
FH type fume hood, except P series is PP material, others are all steel
Product features of all-steel fume hood: Compared with steel-wood structure, it has higher strength, will not produce a lot of deformation due to humidity and temperature changes, and has a long service life.
The characteristics of PP fume hood are used in clean rooms with high environmental requirements, and are suitable for strong acid and alkali experiments.
