EVTTS In line silenced fans
Description
Fans for circular ducts with acoustic insulation and single-phase motor.
Characteristics
- External housing is made of black vermiculated steel, resistant to corrosion and weathering;
- Internal housing perforated to allow the passage of sound waves, directing them toward the sound-absorbing material at a controlled angle;
- Internally insulated for thermal and acoustic performance with a 50 mm layer of mineral wool;
- The combination of special perforations and sound-absorbing material ensures effective noise attenuation across a wide frequency range;
- The internal housing and impeller are made of high-quality plastic, durable and resistant to wear and humidity;
- Protection rating IPX4, providing protection against water splashes from all directions.
Use
The EVTT-S inline fans are housed in a specially designed, sound-insulated casing that ensures quiet operation while maintaining high aerodynamic performance. They are compatible with circular air ducts with diameters from 100 to 315 mm.
EVTT-S fans combine the large capacity and high performance typical of both axial and centrifugal fans, providing powerful airflow and high pressure.
They are recommended as components of air handling systems in commercial and industrial environments with strict noise requirements, such as libraries, conference rooms, schools, and kindergartens.
