Material description of all steel fume hood or fume hood A. structure: the three section combined type cabinet, the upper body (ventilation cabinet), middle (operation table), the lower cabinet (cabinet designed to accommodate independent exhaust type composition containing unilateral cabinet and the other side of the independent water and electricity, pipeline system.
B. shell: the use of thick 1.2mm (including) above the steel plate stamping production, the surface of the acid and alkali resistant EPOXY powder coating treatment.
C. inside the shell: the use of imported acid and alkali fume hood lined with special ventilation cabinet, thick 6mm white surface SOLID PHENOLIC COMPOSITE LINER laminate chemical plate installed.
D. table: the use of laboratory dedicated ceramic plate (high temperature 1200 degrees Celsius) or the use of 304, 316L stainless steel production. It has the advantages of corrosion resistance, antibacterial and antistatic.
E. lighting: 30W fluorescent lamp
F. handle: adopt SUS304 stainless steel sub light square handle.
G. flow plate: using 6mm special thick compact air ventilation cabinet plate, installation position and angle to the exhaust distribution uniformity, no dead angle, under normal conditions, the diversion plate and middle and lower outlet exhaust volume proportion of each of about 50 - 10%, to ensure that the different proportion of gas can be effectively excluded, and the other a manually adjustable exhaust volume ratio design, can improve the middle and lower outlet exhaust volume ratio to 80% above, in order to adapt to the needs of different experiments.
H. window: 5mm thick tempered glass. Internal use of pituitary balance device, can stay in the upper and lower positions.
I. cabinet door open and high: 600 ~ 700mm.
J. working face wind speed: 0.4 ~ 0.6m/s.
K. exhaust air volume: 1080 ~ 1400m3/h.
L. exhaust resistance: 5 ~ 12mmH2O.
M. operating voltage: AC220V ~ 380V.
N. motor power: 0.04 ~ 2.2kW (reference).
O. electrical accessories: universal socket (220V/10A), fluorescent lamp, fan control.
P. water: 1 group DN25. (configured as user requirements)
Q. water: 1 groups of DN50. (configured as user requirements)
R. outlet size: Phi 300mm.
S. fan: the use of glass fiber reinforced plastic materials, acid and alkali resistance, anti-aging.
T. duct: the use of glass fiber reinforced plastic materials, acid and alkali resistance, anti-aging. Main features:
Safety
The three baffle plates cause the harmful gas in the different height space to be discharged from different sections. The fume hood is used to discharge air in the fume hood at the speed of 0.5m/s of the operating surface wind speed to ensure that no residual gas exists. The ventilation efficiency is high, the exhaust air volume is 450-1600m3/h, and the noise is small. The utility model can provide more safe and comfortable test space for the experimenter.
Intelligent control
Ventilation ventilation fan ventilation, water, electricity, gas and ventilation integrated panel control, can be equipped with anti-corrosion, explosion-proof lighting, multi-function (three-phase, single-phase) socket. Gas pipeline and multiple water pipe interface. The utility model can meet the requirements of water, electricity and gas used in various experiments.
economical efficiency
Compared with the traditional bypass cabinet, in the air conditioning environment, can save about 50% of energy.
