This European Standard specifies requirements for the design, construction and operation of the air duct in commercial kitchens, including technical safety, ergonomic and hygienic features.

This European Standard is applicable to ventilation systems in commercial kitchens, associated areas and other installations processing foodstuffs intended for commercial use. Kitchens and associated areas are special rooms in which meals are prepared, where tableware and equipment is washed, cleaned and food is stored and food waste areas.

This European Standard is applicable to kitchen ventilation systems except those used in domestic kitchens.

A method of verification of each requirement is also specified.

Unless otherwise specified, the requirements of this standard should be checked by way of inspection and/or measurement.

NOTE Please note the possible existence of additional or alternative local national regulations on installation, appliance requirements and inspection, maintenance and operation.

4 Construction and function

4.1 General

Unless otherwise specified, the requirements shall be in accordance with EN 12237.

4.2 Functional requirements 4.2.1 General

Air ducts shall be planned and constructed in such a way to ensure low energy consumption, low leakage, low heat loss and favourable sanitary conditions during their operation.

Any adverse hygienic effects of the food shall be avoided.

The stability of the air ducts, their connection and mounting elements shall be dimensioned appropriately to ensure that it will permanently withstand the stress and load caused by operation.

Flexible supply air ducts shall be avoided as far as possible due to difficulty in cleaning.

4.2.2 Design and loss of pressure

Air ducts shall be designed in such a way to ensure minimum loss of pressure.

This may be achieved by:

a) longitudinal and cross-connections which are flush at the inside,

b) stiffening elements that are placed on the outside to avoid high air resistance,

c) air rerouting without sharp edges, inner radius at least 100 mm, junctions preferably with guiding elements,

d) no sudden changes in cross section,

e) in the case of changes in the cross-sectional angle of inclination shall be less than 45°

f) smooth internal walls and joints.

4.2.3 Special requirements for extract and outlet air ducts

Extract and outlet air ducts and their connections shall be aerosol-proof and visible escape of aerosol is not permitted.

Soldered/brazed or welded connections or connections with permanently elastic and aerosol-resistant sealing materials are deemed appropriate and may be used.

The use of flexible air ducts is not permitted.

Chinamans hat type exhaust air outlets shown in Figure 1 shall not be used.

Silencer materials shall not release any harmful substances, such as gases or parts of fibres.

The surface of silencers shall be abrasion-proof, smooth, easy to clean and when installed in extract and outgoing air ducts they shall be liquid-proof, water-resistant, and resistant to aerosol.

Silencers shall be packaged appropriately for transport and storage to avoid any contamination.

It shall be possible to dismantle silencers using basic tools.

4.2.6 Dimensioning of air ducts 4.2.6.1 Flow velocity guide values

For dimensioning of air ducts, the flow velocity guide values as shown in Table 1 shall be used, subject to the permissible sound pressure and pressure loss.
