Blæsere

Blæsere is a Norwegian term with several related meanings. It most commonly refers to wind instrument players in music, but it also denotes machines that move air in ventilation and process applications.

In music, a blåser is a performer who plays a wind instrument. The category includes brass players (for example trompet, trombone, tuba) and woodwind players (for example fløyte, klarinett, obo, fagott). In orchestras and bands the term is used to distinguish instrument families rather than individual instruments. The word derives from the verb blåse, meaning “to blow.”

In engineering and industry, blæsere are devices that increase air movement. They range from small cabinet fans to large industrial blowers. Common types include axial blowers (high-volume, relatively low pressure) and centrifugal (radial) blowers (higher pressure). They are driven by electric motors, diesel or gas engines, or steam turbines, and are used in HVAC systems, manufacturing, mining, wastewater treatment, and electronics cooling. Performance is described by airflow (cubic meters per hour or CFM) and static pressure (Pascals or inches of water).

Blåsere also appear in other technical contexts as general-purpose air movers in processes that require controlled ventilation, drying, or combustion air. Related terms include vifter (fans) and specific blower designs for applications such as air handling, dust collection, and industrial combustion. The concept centers on converting mechanical energy into directed air flow to achieve cooling, ventilation, or material handling.
