Pölyputki

Pölyputki is a Finnish term that translates to "dust pipe" or "dust tube." It is not a specific, universally recognized object or concept with a defined technical or scientific meaning. Instead, the term can be used in a few different contexts, often referring to a conduit or channel designed to transport or contain dust.

One common use of the term is in relation to vacuum cleaning systems. In some older or simpler domestic vacuum cleaners, the flexible hose that connects the vacuum unit to the cleaning head might be colloquially referred to as a pölyputki. This tube carries dust and debris from the surface being cleaned to the collection bin or bag. Industrial vacuum systems or dust collection units used in workshops or factories also employ various types of pipes and ducts to manage dust, and these could also be described as pölyputki in a general sense.

The term might also appear in discussions about ventilation or air filtration systems where dust is a concern. For example, in certain types of dust collectors found in woodworking or metalworking shops, the ductwork that funnels dust away from the machinery and towards a filter could be considered a pölyputki. Essentially, any tube or pipe whose primary function is the movement or containment of dust particles can be generally described as a pölyputki in Finnish.
