| OV 350-450 | Wall square plate | 1 phase 230V / 3 phase 400V | 50/60Hz | 2,590-5,350 m3/h | 140-325 W |
| OV 500-630 | Wall square plate | 1 phase 230V / 3 phase 400V | 50/60Hz | 5,380-12,400 m3/h | 220-979 W |
| OV 710-800 | Wall square plate | 3 phase 400V | 50Hz listed | 12,000-25,000 m3/h | 700-1,850 W |
Wall mounted low pressure axial fan for high airflow ventilation
The OV wall mounted axial fan is a low pressure axial fan in a steel casing, designed for wall surface mounting by means of a square mounting plate. It is used where large air volume is required with relatively low system resistance.
Typical project uses include industrial exhaust, warehouse ventilation, workshop air removal, supply air, and direct wall discharge. The catalog also notes that OV fans can be used for pressurization in smoke ventilation systems when selected for the project design.
For Saudi Arabia projects, selection should be reviewed by airflow, wall opening size, voltage, frequency, motor phase, controller requirement, and installation environment.
Key features for OV wall mounted axial fans
The OV series is built for practical wall ventilation where high airflow, simple installation, and project-ready selection matter.
