1. Description
Designed to solve the high energy consumption of traditional laboratories, reduce the cost of enterprises, and protect the safety of laboratory personnel in experimental operations, it can prevent operators from inhaling some toxic and harmful, curable or unclear in the laboratory. The chemical substances in the university purify the fume hood and the air in the laboratory to provide safety protection for the laboratory personnel, and it does not deplete the energy consumption of the air conditioner, and does not discharge exhaust gas and does not pollute the environment.
2. Feature
Ductless fume hood principle
1. Air inlet
Air can be pumped directly into the fume hood from the laboratory to create a negative pressure that creates a natural barrier to isolate the user and the chemicals they operate.
2.Comprehensive filtration system
The fan system sucks in toxic and harmful gases, filters it and returns clean air to the room. The excellent control concentration of the cabinet ensures that the chemical gas in the cabinet will not return to the room, causing pollution.
3. Clean laboratory air
Different filters are configured according to different operations to effectively filter toxic and harmful gases, purify laboratory air, remove chemical residues and improve laboratory cleanliness.
Technical advantages
1. Humanized three-door design
2. Large LCD screen displays surface wind speed, filter saturation state, ie filter working temperature, fan working speed
3. VAV system, according to the door opening height, the fan changes the speed in real time, self-adjusts the air volume, and ensures the surface wind speed is 0.5m/s safe wind value.
4. Can access a variety of different gases or liquids, directly control the flow outside the cabinet
5. Reserve multiple laboratory dedicated sockets to provide different small instruments to work in the cabinet at the same time.
6. Optional remote monitoring system, 24-hour wireless monitoring through the client
7. Energy saving and better energy saving effect
8. The adsorption capacity is stronger and can replace the traditional outer ventilation fume hood.
