Advantage of the present utility model and beneficial effect are:
1, this current-sharing plenum chamber casing is overall structure, and its good sealing effect has been stopped the loss because of the poorly sealed blast that causes and air quantity.Air is from casing two side inflows, drive through high efficiency filter by the turbine centrifugal blower and send, thereby the equilibrium that has reached air in the airtight cabinet flow, and then guaranteed experiment carry out accuracy with experimental result smoothly.
2, this current-sharing plenum chamber adopts special cold wind flow equalize technology, and gas circulation is more stable.
3, the blower fan that adopts of this current-sharing plenum chamber is the turbine centrifugal blower, and this blower fan has that volume is little, low noise operation (advantages such as noise＜60dB), power save function, environmental protection and energy saving.
4, this current-sharing plenum chamber critical piece all adopts 304 high-quality stainless steels to make, and it is corrosion-resistant and acid-proof alkaline is good.This casing is easily manufactured flexibly, can specifically make according to the size of customer requirements.
5, this current-sharing plenum chamber adopts bolt and compress gasket that the high efficiency filter device is fixed, so high efficiency particulate air filter replacing easy to assemble.
6, this current-sharing plenum chamber casing left and right sides air inlet utilizes the stainless (steel) wire shutoff, can filter the larger particles foreign material, has dustproof effect.
7, the utility model is a kind of reasonable in design, outward appearance brevity and lucidity, is difficult for laying dust, practical laboratory with the special-purpose current-sharing plenum chamber of airtight cabinet.This plenum chamber can be used for some experiments provides a good gas circulation space with the self-cleaning of airtight cabinet or for experiment, the equilibrium that guarantees air in the airtight cabinet is flowed, the order experiment can better be carried out, obtain experimental data more accurately, filled up that China tests at high-end microbial aerosol, the blank of equipment aspect the military microbe research test.
