Outward, pollution, purify air are reduced, and there is gas defence, explosion-proof safety guarantee to act on.
Range hood majority traditional in the market is top suction type, and oil smoke is taken away by ventilating fan above, and top is inhaled
Formula range hood has slim, deep type and half deep type for falling between etc..Slim range hood is very shallow because of exhaust fume collecting hood, it is impossible to
The effect of rapid pump drainage oil smoke is reached, oil fume pumping-clean rate is only 40% or so.And deep type smoke exhaust ventilator is deeper because of exhaust fume collecting hood, row
The oil smoke of non-emptying can be temporarily housed in exhaust fume collecting hood during wind, this avoid showing for the part oil smoke diffusion for failing to drain for the moment
As, cushioning effect is played, the effect of its pump drainage oil smoke is better than slim smoke exhaust ventilator, and oil fume pumping-clean rate is in 50%-60%.Top suction type
Not only oil fume pumping-clean rate is low for range hood, and majority is all mounted in cooking stove top, can be brought during cooking meet and discuss, oil dripping etc. it is all
Inconvenience more.And side extraction cooking fume extractor changes the design of conventional smoke machine and smoke pumping mode, the oil that will be produced from side during culinary art
