" VENTS TT SILENT-M 250 R MIXED-FLOW VENTILATOR Ø 250 MM / 1110 M³ + 1400 M³ "
The Vents TT Silent-M 250 R Mixed-Flow Fan has a soundproof housing made of polymer coated steel. The design not only guarantees silent operation, but also excellent aerodynamic properties. The inside is made of high quality durable plastic with a heat and sound insulating layer of 50 mm mineral wool.
The VENTS TT Silent-M fans combine the many possibilities and high performance of both axial and centrifugal fans, providing powerful airflow and high pressure. This type of fan is recommended as part of air handling systems for various commercial and industrial buildings with high noise level requirements, such as libraries, conference rooms, educational establishments, kindergartens, etc.
The Vents TT Silent-M 250 R Mixed-Flow Fan has a soundproof housing made of polymer coated steel. The design not only guarantees silent operation, but also excellent aerodynamic properties. The inside is made of high quality durable plastic with a heat and sound insulating layer of 50 mm mineral wool. Thanks to the use of sound absorbing material and perforations on the inside, sound attenuation over a wide frequency is achieved. The sound waves are guided through the holes and attack the sound-absorbing layer at a specific angle for the quietest possible operation.
Another advantage is the higher air pressure and air capacity compared to standard axial fans. This is partly due to the conical rotor and the specially developed profile. The diffuser, impeller and guide vanes ensure that the air flow is distributed in such a way that the best combination of high performance, increased pressure and low noise level is achieved.
The fan is equipped with a single-phase, energy efficient motor with thermal overload protection to prevent motor overload. The ball bearings extend the life of the motor up to 40,000 hours in non-stop operation. You can control the speed with an external switch for multi-speed fans (sold separately).
Mounting the fan is very easy. It can be mounted anywhere and at any angle in the ventilation system. With the corresponding mounting brackets you can attach the fan to the floor, wall or ceiling. Installing multiple fans in parallel within one system is no problem. Also handy: the fan is supplied with cord and plug.
