VENTS OV1 315 axial fan, 1700 m3/h, low-pressure, wall-mounted

Vents OV1-series axial fans are designed to move large air volumes at low pressure, with wall- or panel-mounting capability. They are used for ventilating commercial, office and other public or industrial spaces. The fan has an asynchronous single-phase motor with built-in thermal overheating protection and automatic restart.
