The latter, above all, is given by the impossibility of calculating everything to the detail.<\/p>\n

The variables that can disturb normal extraction operations are, indeed, countless.<\/p>\n

One of these is the presence of staff in the kitchen. Whether it’s the chef or simply the commis busy taking the dishes to serve.<\/p>\n

One scientific study talks about this: “Effects of Mannequin and Walk-by Motion on Flow and Spillage Characteristics of Wall-Mounted and Jet-Isolated Range Hoods<\/em><\/a>” (R.F.Huang; G.-Z.Dai; J.-K.Chen. 2010).<\/p>\n

It demonstrates, using laser display technology, how cooking fumes (especially oil) are attracted by the cook and the staff in front of the cooking area.<\/p>\n

Furthermore, the operators who, presumably, walk in the surrounding areas (imagine a kitchen during rush hour…), will create some sort of “turbulence” which will affect the dispersion of fumes (less so in the case of wall hoods, however).<\/p>\n

A solution? Well, perhaps the only one is to set up a staff “walk-by” area as far away as possible from the cooking area, as the “disturbance” decreases as the distance increases.<\/p>\n

It would also decrease with a reduction in the speed of said walk-bys: imagine a kitchen during rush hour tho… that is way far from possible!<\/p>\n

Oh, one more thing! There is no point in increasing the suction flow rate: this leaves the situation almost unchanged.<\/p>\n

However, our advice is always the same: take advice from a good technician.<\/p>\n
