Various areas of a retail shop (including stockroom, storage area, warehouse, etc.) are subject to various sources of pollution. The food items being sold and the customer movement in the shop lead to the formation of dust. Similarly, for the food products industry, the hygiene-related (HACCP) laws are strict. The tasks involved in the production and preparation of the food products must be performed in a hygienic manner. Therefore, the dust particles must be controlled to ensure food safety, the health of workers and to avoid machine malfunctions. The negative consequences are significant for the hygiene of the products (HACCP), the customer (image) and the health of the personnel. Therefore, dust extraction in the shop and in the food industry is a necessity.
