Anhui Huasheng fume agent - wholesale fume hood - hood [price, brand assurance] 
 Laboratory design, laboratory ventilation, an indispensable component. For laboratory staff do not have inhaled or swallowed into some ***, can be pathogenic or toxic unknown chemicals and organisms, the laboratory should have good ventilation. To prevent some of the steam, gases and particulates (smoke, soot, dust and gas hanging body) absorption, pollutants have to use fume hood, ventilation hood or local exhaust ventilation to remove the method. 
 Hood structure is up and down style, the top vent, the fan can be installed. 
 OTC has deflector, circuit control touch switches, electrical outlets, etc., the use of transparent window glass, left or right or up and down. For people to operate. Under the cabinet table style using experimental side, above the table, here is the cabinet. Table can be installed and leading a small cup. Fume hood by a variety of materials, steel, steel and wood, all wood, aluminum, wood, plastic, PVC structure, the table is directly in contact with the operator places the solid physics and chemistry panels, stainless steel, PVC, ceramic and other materials. Old multi-purpose fume hood made of wood, but modern, mostly made of steel coated with epoxy resin. Common cabinet width of 1000,1200,1500,1800 and 2000 mm a few specifications, depth 700-900 mm, height 1900-2400 mm. For 1-3 individuals simultaneously. Fume hood is generally against a wall. Can be moved up and down the middle in front of the transparent door (mostly glass), open the height is 100-600 mm. Experiments carried out after the door face, there are water pipes, sewers, power supply, vacuum pump, gas pipelines and other experiments need to connect, with protective cover on the lighting. Air from the cabinet above the fan pulled out before, after, or by pipe to somewhere else (known as full ventilation), or re-recycled through a filter (a ductless ventilation). Most fume hoods in (1) displacement is too small (2) in front of large glass doors open when the alarm will alert the operator attention. The internal fan speed and light switches are adjustable. When people use the stand or sit on the counter before it will try to lower the glass doors, hand under the door into his cabinet by experiment. As the fan exhaust through the open door inward, under normal circumstances, a large number of harmful gases will not overflow.
