AIR BLOWERS

Air Blowers, by EVANAIR, are electrical machines that generate high volumes of Air Flow at lower discharge pressures. Various different methods of technology are used to generate the exact Flow Rates and Discharge Pressures required by customers and system processes.

HOW DO AIR BLOWERS WORK?

Air Blowers make use of a high speed spinning action, to draw in the atmospheric air surrounding them, through an inlet port, and to discharge that air through a discharge port. The actual achievable performance depends on a number of factors, such as design technology as well as atmospheric conditions.

HOW ARE AIR BLOWERS DESIGNED?

Air Blowers have been designed using many differing methods of technology. Over the years, many new designs have been tried and tested. At EVANAIR we focus on two primary technolgy methods. Side Channel Blowers, using a single spinning impeller that creates air flow using centrifugal force, and ROOTS Blowers, utilising the positive displacement effect of close meshing rotors, to genereate suction and forced discharge of air.

HOW DO AIR BLOWERS PERFORM?

Air Blowers do not compress air. This is an often made mistake. By definition, an Air Blower is not an air compressor. An air blower works on the principal of drawing air in and discharging it. Except for the forced discharge, there is no air compression. An Air Blower works on a maximum compression ratio of 1:1. This mean that it does not compress air. It simply blows it. 

DOES ATMOSPHERIC AIR AFFECT AN AIR BLOWER?

Atmospheric Air is the air surrounding a particular location and is not a constant value. Atmospheric Air can be influenced and changed by altitude, temperature and humidity. The atmospheric air pressure surrounding an Air Blower will determine the overall possible performance of the unit. At “Normal Conditions” defined as 0m asl, 0deg C and 0% R/H, the atmospheric air is 1,013 mbar (a). This value will decrease with changes in altitude, temperature and humidity. Therefore, with a compression ration of 1:1, an Air Blower is only able to blow out what it can suck in. i.e. a maximum discharge pressure of 1,013 mbar(a). The volume of air being blown at this discharge pressure can be changed and controlled by using bigger or smaller selected models, or by changing the operating speeds.
