The pp fume hood should be mainly due to the high requirements of the clean room environment, because the PP material has excellent acid resistance, compared with the entire steel fume hood, acid alkali resistance is excellent, which can make the acid alkali strength is higher. Lithium-ion battery experiment. Replacement of all steel ventilators is possible. It can be applied to high end of purification places such as high intensity acid alkali experiments. Applicable to special chemical industry, suitable for high acid alkali, corrosive special environment to use pp ventilator. It is one of the suitable engineering plastics due to its low density, chemical resistance, heat resistance, impact resistance, non-toxicity, odorlessness other characteristics. Uses: acid alkali resistant equipment, environmental protection equipment, wastewater, exhaust gas discharge equipment, scrubber tower, clean room, semiconductor factory related industrial equipment. All-steel fume hood is one of the local exhaust equipment commonly used in laboratories. There are many kinds of them. Due to their different structures conditions, their exhaust effects are different.

Different types of pp fume hoods have different characteristics:

First: Fume hoods with slits.

This type of fan is constructed with a slit on its top back, thus ensuring good ventilation regardless of any type of operation any working conditions. However, the disadvantage of this type of ventilator is that its structure is more complicated than the types of fume hoods, the production process is very complex requires a lot of labor material resources, so the production cost is also high, so it is more expensive.

Second: Bypass type ventilator.

Because we all know that in the experiment, in order to carry out the experiment smoothly, we choose to ensure that the experimental environment has good ventilation performance, for example, we need to use some amplitude ventilation to consume. At this time the good choice is to choose the bypass ventilator, because even if we close all the ventilator cabinet doors, it will have any effect on the air exchange rate of the room. This is very practical.

Third: Fume hoods with automatic ventilation.

The most significant feature of this type of ventilator is that it does require a large amount of electrical energy consumption can also be realized for long periods of time, such as all day night for different jobs, thus ensuring an effective exchange of air in the room without noise. Vibration during work.
