EVTT BOOST In-line circular duct fans for air volumes up to 3350 m³/h

Single-phase 3-speed circular duct fans with high efficiency and low energy consumption.

Housing:
- Made of black polymer;
- For Ø 355 and 400 models, the housing is reinforced with a metal frame for enhanced durability.
Impeller:
- Conical polymer impeller with specially profiled blades.
- Increased air velocity, resulting in:
  - Higher airflow capacity;
  - Higher pressure compared to standard axial fans.
Airflow Optimization:
- Diffuser, impeller, and flow straightener at the fan outlet;
  - Ensures uniform air distribution;
  - Provides the best combination of high airflow, increased pressure, and low noise level.
Electrical Connection:
- The fan housing is equipped with an IPx4-rated terminal box for safe connection to the electrical network.

The units are designed for supply or exhaust ventilation systems requiring high airflow, suitable for:
