Abstract (en)

[origin: US4462305A] An aspirating device for the ejection of gases or fumes has dynamic primary and static secondary extraction means. The static secondary means has lower and upper elements configured in pseudo-frustoconical forms. The upper and lower elements are rigidly fixed to one another. The dynamic primary means are active or passive dependent on the desired level of flow of the ejected fluid.
