Almost every chemical laboratory will have fireproof cabinets. We use fireproof cabinets to store organic solvents, acid and alkali, flammable and explosive materials, other solids, etc. Fireproof cabinets have made significant contributions to the classification and storage of chemicals, but As everyone knows, it is understood that most of the laboratory fire cabinets are not equipped with a professional ventilation system, that is, when the cabinet becomes a relatively closed environment, the chemicals in the cabinet will continuously release gas, and the concentration inside the cabinet will become larger and larger. On the one hand, the gas is released to the inside of the laboratory, and on the other hand, too high a concentration may cause safety hazards such as spontaneous combustion or even explosion.
Taicang Huafeng Company has developed a filtration device specifically for fireproof cabinets for the current situation of most laboratories, as shown below:
Device principle:
The inside of the cabinet is equipped with a fan and a filtering system. The air in the fireproof cabinet is pumped to the filtering device through the connecting pipe for filtering, and the clean air is discharged into the room.
Product advantages:
The use of fire cabinet filter unit will bring you:
1 , Â Safety: The problem of chemical volatilization is solved from the source by purifying the air in the cabinet;
2 ,  Clean: The 70m ³ / h air handling capacity uninterrupted purify the air, reducing the clean laboratory;
3 , Â Convenient: easy to install, use the metal connection pipe link to power up after arrival;
4 , Â Environmental protection: purification of toxic and hazardous chemicals, not directly discharged into space, environmental protection;
5 , Â Energy saving: the air conditioning air is not discharged to the outside, saving most of the energy consumption;
6 , Â Personal protection: The filtration system can effectively filter the toxic air in the cabinet, and will not inhale harmful gases when you open the cabinet.

product structure
Metal parts: main material is 1.2mm galvanized steel plate coated with epoxy polyester coating resistant to acid and alkali ;
Filter module: activated carbon filter and polypropylene
Filter: Optional YJ type filter, mainly for organic vapor type filter TY, acid gas and organic gas adsorbing ability, the HEPA filter, H14, for the particle filter, a particle larger than 0.3 μ m, the filtration efficiency Up to 99.995% .
Interface: anti-electromagnetic interference power cord.
Metal connection tube: Standard size, matched to fire cabinet.
Accessories
LED display: computerized control panel, showing the temperature inside the cabinet; online display of fan speed, wind speed is too high or too low will alarm reminder;
Wind speed adjustment: The fan speed can be adjusted automatically. As the filter increases with the use time, the pressure loss becomes larger. To ensure the safety surface wind speed, CUP monitors and adjusts in real time.
Optional accessories
1.1 Filter monitoring system: It can monitor the chemical concentration change of the filter outlet in real time and display the ppm value. The alarm point can be set.
1.2 TVOC monitoring system: real-time online monitoring of air TVOC conditions in the laboratory and display of ppm values
