Comparison Interline Blow S IX A/60/PB stainless steel vs Interline Smart S WH A/60/T white

The maximum flow of air or motor flow of air indicates the theoretical capability of the device. This parameter of the hood (motor) is measured during idle operation. By connecting the duct and working in the appropriate mode of extraction, the flow of air will be lower. However, high-performance motors will also give a high flow of air in extraction mode.

The volume at which the device operates in the quietest mode. Usually (but not necessarily) it is the minimum power mode.

The decibels in which the noise level is measured are non-linear units, so it is easiest to use comparison tables to estimate a specific value. Here is the simplest table for minimum noise in modern hoods:

— 20 dB. Almost inaudible. The volume of a whisper at a distance of 1 m, the sound background in an open field on a calm day.
— 30 dB. The whisper, the ticking of the clock. The maximum noise level allowed for residential premises at night.
— 40 dB. The volume of normal human speech. The maximum permissible sound background (permanent) for living quarters during the day.
— 50 dB. Conversation of several people in medium tones.
— 60 dB. Loud talk.
— 65 – 68 dB — background noise on a city street, a vacuum cleaner engine at a distance of 2 – 3 m. The highest noise level among modern hoods is typical for powerful performant models.

When choosing according to this indicator, note that, other things being equal, a quieter device will, accordingly, cost more.
