Many laboratories will choose to use pp fume hoods,  the use of pp fume hoods will encounter problems, then we will encounter what common problems? How to solve?

First. Problems

1, pp fume hood face air velocity with pp fume hood cabinet door control, safety requirements to maintain to the specified range, in order to effectively control pollution, to protect laboratory personnel.

2, chemical laboratories require full fresh air control,  chemical laboratories generally have temperature requirements, when using full fresh air, energy consumption is very large.

3, the safety requirements of chemical laboratories need to be controlled for negative pressure,  pp fume hood air volume for variable air volume, air supply, exhaust air volume are changing, the need for automatic control to maintain negative pressure.

Second, the solution

The use of variable air volume control device can effectively solve the above problems:

1, the use of pp fume cupboard variable air volume control device, can be timely  effective to keep the surface wind speed control in the effective range.

2、When using the variable air volume control device, it can effectively maintain a lower air volume according to the use of the situation, to achieve the purpose of energy saving.

3、Variable air volume control device can effectively adjust the value of air supply  exhaust air volume to achieve the purpose of negative pressure in the laboratory.
