Abstract
The invention relates to a fan driven by air/gas from a compressor, being applicable both to the industrial, air-conditioning, venting field and to the field of conveying gases or other mixtures. According to the invention, the fan comprises a cylindrical support (1) which is tightly mounted in a duct network consisting of some sections (4 and 5), a housing (7) playing the role of manifold being secured inside the cylindrical support (1), by means of a locating-securing system (A) consisting of the supporting members (6), said housing accommodating two turbines, known per se, integral with two shafts (14 and 15) having two separately driven coaxial airscrews (16 and 17) mounted thereon, said airscrews having three and four blades, respectively. The air/gas supply is made through the existing installation (9 and 10) and a connection (8) located in one of the supporting members (6) and the turbines discharge is carried out inside the duct.
