The blower is used for glass blowing, and is specially suitable for blowing pipes and 

 sirens in conjunction with the employment of a wind chest. The blower works very well with 10 m 

 water pressure (1 atmosphere). As it delivers large volumes of air at medium pressure, it is preferable 

 to any injector blower.
