The wall-mounted exhaust fan High-capacity axial ventilators HQ/HW/HS/HRF Helios HQD 710/12/6..° is equipped with a galvanized sheet-steel mounting bracket.
Design of the wall-mounted industrial fan High-capacity axial ventilators HQ/HW/HS/HRF Helios HQD 710/12/6..°
The High-capacity axial ventilators HQ/HW/HS/HRF Helios HQD 710/12/6..° fan features a high-performance impeller with 7 profiled plastic blades, dynamically balanced. Operating temperature range: –30…+60 °C.
Models HQ and AVD DK include a protective grille made of steel with hot-dip galvanizing or powder coating, compliant with DIN EN ISO 13857.
High-capacity axial ventilators HQ/HW/HS/HRF Helios HQD 710/12/6..° is fitted with a Dahlander winding.
Blade pitch of the industrial wall fan High-capacity axial ventilators HQ/HW/HS/HRF Helios HQD 710/12/6..°
To achieve optimal performance, the fans use impellers with adjustable blades. The blade angle is set at the factory (per order). Motor selection is based on maximum power as shown in the table below. Exceeding these specifications is not permitted.
Motor of the high-power exhaust fan High-capacity axial ventilators HQ/HW/HS/HRF Helios HQD 710/12/6..°
Closed-drive design. Protection rating IP 54 or IP 55, fitted with ball bearings. Maintenance-free and does not generate radio interference. The winding is moisture-protected by dipping.
All models are equipped with thermal contacts; to protect the motor effectively, they must be connected to a motor-protection breaker.
Electrical connection of the axial wall fan High-capacity axial ventilators HQ/HW/HS/HRF Helios HQD 710/12/6..°
Via a standard terminal box (protection rating IP 55) mounted on the rear of the motor. In HRF models, the terminal box is additionally mounted externally on the housing.
Power control of the axial fan High-capacity axial ventilators HQ/HW/HS/HRF Helios HQD 710/12/6..°
All models can operate in reverse mode, controlled by a DSEL switch. Volumetric flow in reverse mode is reduced by approximately one-third.
Installation and orientation of the high-power axial fan High-capacity axial ventilators HQ/HW/HS/HRF Helios HQD 710/12/6..°
Installation is possible in any orientation; consider the location of condensate drain holes based on operating conditions.
