    Low noise level
    Acoustic insulation of 7 mm thickness flame retardant (M1) melamine foam reducing the noise level significantly.

    Flexible coupling at the discharge
    To reduce vibration and noise transmissions to the installation.

    Quality finishing, with aluminium corners providing a high robustness.

    Versatile outlet discharge
    Vertical discharge models available under request.

    Anti-vibration mounts
    The fan is mounted on base frame with silent-blocks to reduce vibration and noise transmissions to the installation.
