What is a blower?

A blower is a device that pushes out gases by imparting energy to increase its pressure and speed.

They range from the large blowers found in applications such as production machinery and clean rooms, to the small blowers built into devices such as home appliances or personal computers, and are used to blow air for exhausting ventilation or cooling.

Historically, among the very first blowers were the bellows used to supply air during the smelting of iron. Mentions of these bellows can be found in the literature of ancient Rome and China. Bellows were at first manually operated, then underwent various enhancements over time including the use of water power, evolving into an efficient means of supplying air.

In more recent times, the arrival of new power sources such as steam and electricity led to the development of a variety of other pneumatic (air-driven) equipment. Example applications include air brakes in steam locomotives and the opening and closing of automatic doors.

Nowadays, blowers and compressors used in various industries, and are built into equipment such as sorting or transportation machines, and processing or assembly, and packaging equipment. They are also found in products such as computers and home appliances, where they facilitate size reduction and performance enhancement.

The American Society of Mechanical Engineers (ASME) defines the difference between compressors, blowers, and fans in terms of discharge pressure/suction pressure ratio as follows:

As you can see, blowers occupy the middle range between fans and compressors.

While blowers come in many different types, ASPINA supplies centrifugal blowers; mainly multi blade or turbo types.

The key to blower development is to study the electric motor, fan, casing, circuitry, and other components in detail to build up an accurate understanding of where performance losses occur. ASPINA draws on their expertise built up through many years of blower development, not only to optimize fans and their motors and improve their performance, but also to make them smaller, lighter, have longer operating times, and able to run quietly with low vibration.
Along with providing greater flexibility in product design, ASPINA blowers can help reduce costs. ASPINA also has extensive scope for customization, so please don't hesitate to contact us.
