All the steel Fume Hood of the shell is the choice of metal raw materials or other materials, the table is made of stainless steel with anti-acid, heat, flame retardant personality.At the same time, the whole steel Fume Hood to adopt the mysterious exhaust It is possible to meet the needs of the science and the industrialization process of the bustling, scientific experiments must be reduced, the boundaries of the laboratory repair has been swept by the number of years Carried out in the laboratory through the test, accompanied by the detection of harmful substances such as gas, steam, dust and suspended particles, such as the show off, the strength of the test staff into an emergency damage.
All the steel Fume Hood is a serious safety development in the laboratory furniture, can focus on the fume machine dull machine equipment disturbance, chemical reaction or hot heat, and indoor horizontal airflow intervention and other causes of harmful substances escape. Gas density and air density of different sizes, all the steel Fume Hood a lot of names, the main forms include: the upper exhaust Fume Hood, the lower exhaust Fume Hood, up and down the exhaust ventilation cabinet. At the same time, another energy-saving Of the steel Fume Hood.
In order to control the spill of the harmful substances and to ensure that the usual correction, must control the wind speed. Cabinet surface wind speed selection principle is: it is necessary to make the harmful gas from the cabinet to escape, but also to prevent the steel Ventilation cabinet turbulence.
Not only that, the upper part of the steel Fume Hood is also built with ventilation holes, even if the glass window cover can be added to the air, to avoid greater negative pressure.With the height of the steel fuselage table in line with the human body, not only easy Manipulation, not to mention the use of space is also large, at a certain level of promotion of the safety, all-steel Fume Hood is the laboratory necessary safety equipment. Full steel exhaust cabinet full extension of all with nano-silver antibacterial coating, Effective control of the surface of the bacterial breeding and cross-infection.Wall steel fume cabinet structure is not the traditional welding structure, but one molded from the suppression, more flat cabinet device more flexible, more durable. Galvanized steel plate action cabinet material, the surface of the powder paint in charge, than the ordinary plating steel plate is more resistant to corrosion.
Therefore, we use the full steel Fume Hood with the following points also need to pay attention to the beginning of the test, the steel Fume Hood to be in the business situation, to carry out the test operation; at the end of the test should run at least 5 minutes to close Ventilator, thus eliminating the residual gas in the pipeline. Modern scientific instruments, intact all-steel Fume Hood is to ensure that the test is normal to hold favorable conditions.
The position of the glass window of the Fume Hood also senses the gas wind speed. For the Fume Hood glass window, he is a transparent position to isolate the gas spill, so that the Fume Hood of the fog is cut off from the poisonous agent. The atmosphere of the atmosphere is affected by the installation of the air diversion. Under the window of the Fume Hood glass, the air diversion device consolidates the air flow into the Fume Hood, thus improving the working efficiency of the Fume Hood. (Modern ventilation Cabinet to the left and right ends of the same air diversion characteristics).
The deflector is located at the bottom of the Fume Hood, which controls the airflow of the Fume Hood.The deflector is located in a position where the efficiency of the Fume Hood can be chosen, and the user may wish to pass tightly to adjust the air flow to the This adjustment does not exceed 5% of all airflow, and the adjustment of the diversion device located at the bottom of the Fume Hood also makes the overall ventilation of the practice room absolutely improve the safety of the Fume Hood.
With a simple ability, the Fume Hood can be considered as a iron cabinet and a fan into the iron cabinet of the gas is destroyed by the fan and safe release to the atmosphere in order to fight these gas workers and apprentices can be cherished.Thus, Mixed Fume Hood operation becomes easy to understand.As we have revealed, many of the sudden changes in the gas easily, weak, toxic gas need to pick up from the talent into the atmosphere, at first, to have a suitable air thrust , Is called "the speed of movement of the gas in a Fume Hood toward a certain deviation" (wind speed). It is felt that the reasonable wind speed is 0.5 m / s daily. In order to keep the wind speed, the number of air or the exhaust pipe Capacity is required. The capacity of the exhaust pipe is measured with the number of cubic meters per hour. The wind speed and the capacity of the exhaust pipe are set by the Fume Hood, the location of the fridge's laboratory, and the dynamic balance of the room gas Impact.
