OJ DV product range - built to meet your ventilation needs

Our range of OJ DV drives comprises 13 output variants (from 0.5 to 15 kW) fitted inside five different housings to match any rooftop fan, plug fan, or AHU application.

Wide ambient temperature range

The robust OJ DV are capable of continuous operation from -40° to +50°. At higher temperatures, the drive will continue operation with lower performance.

In fire mode, the OJ DV overrides the drive’s self-protecting features and can run for one hour in temperatures up to +70° degrees. This means that the OJ DV can be used for smoke extraction; you will not need to install a separate system for that.

Energy efficiency

OJ Drives operate at up to 97% efficiency. Mount them inside the airflow to achieve full efficiency.
