Description

The Vents TT Silent-M 315 fan in a noise-insulated housing is designed for use as part of exhaust or supply ventilation, when it is necessary to ensure a very low noise level from ventilation. The fan can move air with a maximum capacity of 1950 m3/h and a maximum temperature of up to 60°C. It is connected to round air ducts with a section of 315 mm. The fan can be installed indoors with an indoor temperature above +1°C.

This series combines wide possibilities and high characteristics of axial and centrifugal fans. Thanks to this combination, it was possible to achieve high pressure, powerful airflow and low noise levels at a fairly low energy consumption.

Design

The casing of the Venst TT Silent-M 315 fan is made of polymer-coated structural steel. Perforations are made inside the case, which transmit sound waves, directing them at a certain angle to a layer of noise-absorbing material. Noise and heat insulation of the body is made of a layer of mineral wool 50 mm thick. Special perforation of the case and noise-absorbing material provide sound attenuation in a wide frequency range. The inner casing and the impeller are made of high quality and durable plastic.

Housing with sound insulation

Thanks to the conical shape of the impeller and specially shaped blades, the circular speed of the air flow is increased, providing higher pressure and performance compared to conventional axial fans. A diffuser, a specially designed impeller and a straightener at the outlet of the fan housing distribute the airflow in such a way that an optimal combination of characteristics is provided - high performance and increased pressure at low noise levels. The fan housing is equipped with an external sealed terminal box for connecting the power supply. For tight connection with air ducts, the fan connecting pipes are equipped with rubber seals.

Engine

Single-phase, high-efficiency, two-speed motors with low energy consumption are used. Fan motors are equipped with thermal fuses for overload protection. Rolling bearings provide a long service life (about 40,000 hours of continuous operation). Motor protection class - IP X4.

Speed control

The two-speed motor can be controlled by an external switch for multi-speed fans (sold separately).fans (sold separately).
