What is the difference between an air compressor, blower and fan?
The Pro Says: While the industry has not standardized or differentiated in the turbomachinery classes, pressures generated and end use generally determine machine class. Compressors are high pressure units whose main function is to compress the air or gas, increase the pressure or reduce volume. Fans are generally low pressure machines whose primary function is to move gas or air through a system or process. Blowers are high pressure fans which move air above atmospheric pressure to force flow through a fixed resistance. Virtually all the machines encountered in ventilation or exhaust applications for industrial systems will be fans.
