Cooker hood with filter for kitchens - has filter cartridge with sections of different through flow characteristics, for optimum grease deposit

摘要

The cartridge (20) has part sections (24) of the same opening profile, with preferred air flow through them. Other sections (25) block the through flow. Relative arrangement of the different sections can be adjusted according to the intake characteristics of the extractor fan (14). The intake side of the fan is at a min. vertical distance of 100 mm to the discharge side of the cartridge. The filter material (22) is a grease filter. ADVANTAGE - Intake speed of air is maintained constant within a defined speed range, for even grease deposit.
