EM-EC

The tube fans series have been developed for universal use. (Variable mounting position, horizontal and vertical installation possible. Direct in-line installation in the duct network. Integrated mounting bracket for easy mounting. Housing PPGF30 in RAL 7012, basalt grey. By opening the mounting bracket, the housing can easily be rotated to bring the plenum box into the desired position. The significant reduction of flow losses also minimises noise generation and, in combination with the vibration-optimised construction, results in smooth operation. The high-quality construction material has a glass fibre content of 30% and is highly resistant to corrosion and weathering.

Diagonal fan with three-dimensionally shaped blades and a three-dimensionally shaped diffuser on the discharge side. This results in the highest possible aerodynamic efficiency. The impeller is balanced in two planes according to G6.3 DIN ISO1970. Highest efficiency, electronically commutated permanent magnet motor (EC motor).

Thanks to the EC technology, the
ETAMASTER can also operate very efficiently at partial load. The motor is protected in the hub area and does not interfere with aerodynamics. The internal electronic temperature monitor protects the motor against overload. Electrical connection via terminal box integrated in housing
