Structure | The structure of the fume hood is up and down, with a vent on the top and a fan. There are some guide plate on the upper cabinet, circuit control touch switches, power sockets, etc., through the use of tempered glass, can be moved up and down for human operation. The lower cabinet uses the experiment wall bench desk style, above the table, below is the cabinet body. The table can install small water cup and water tap. Fume hood has variety of materials, all steel, steel&wood, aluminum&wood, plastic, PVC structure, the table is the place of direct contact with the operator, the solid physiochemical board, stainless steel plate, PVC, ceramic material composition and so on. The fume hood is generally installed on the wall. The middle of the front is the transparent door (mostly glass)which could be move up and down, open height is generally 100-600 mm.it is a experimental work face after the door.there are water pipes, sewers, power, vacuum pumps, gas pipeline and other experiments need to connect, with a protective cover on the lighting.The air is pumped out of the exhaust fan in front of the cabinet, or through the pipe (known as full ventilation), or by recirculation (ductless ventilated). Ventilation cabinet (1) Exhaust is too small (2) When the front glass door is too large, an alarm will be given to alert the operator. The internal fan speed and the lights are adjustable.
When using the person station or sitting in front of the cabinet, the glass door is as low as possible, the hand through the door into the cabinet to carry out the experiment. Because the exhaust fan is pumped through the open door, the harmful gases do not overflow in normal circumstances. |
Feature | Local ventilation equipment is commonly used in laboratory experiment personnel's operation safety, for the experimental operation timely elimination of toxic and harmful gases, to prevent the spread of pollutants to the laboratory.
1.cabinet body:Fully steel integrated cabinet,use 1.2mm thickness high quality cold rolled steel plate,surface with acid pickling,phosphating and electrostatic power coating epoxidation for acid and alkali resistant and rust prevention.
2.operation table: can choose physiochemical board/PP/stainless steel/epoxy resin/ceramic plate to meet the different demands.
3.The dashboard:The use of touch-button electronic control panel, protection devices, power supply, motor, socket, lighting, leakage, overload short circuit protection.
4.Accessories: with a small faucet and PP small cup, you can also use remote control valve and water nozzle; at the same time according to the need to configure the remote control valve and gas nozzle.
5.Ventilation system: the fan according to actual use require the use of domestically produced corrosion resistance of PP fan, the noise is less than 65 dba: duct site condition using PP duct, straight row of the wall or to the designated location.
6.Lighting: 40W explosion-proof fluorescent one hidden in the panel (illumination of not less than 300LX), not with the ventilation cabinet air contact, easy to replace, and the top of the soft connection to the explosion relief effect.
7.Visual Window:use 5mm thickness anti-etempered glass combination with balance, the balance part is gratuitous type structure design, design of glass door operation left, right, push-pull, upper and lower open, flexible operating procedures, is safe to complete special experiment. |
