Model OH-DR1 & Model OH-VSO

The pendent Model OH-DR1 and Model OH-VSO nozzles have been designed specifically for effective and reliable protection of low risk Light Hazard, Domestic and Residential areas.

Being specifically designed for the protection of these hazard groups, VID Fire-Kill have been able to maximize coverage, while considerably lowering water supply requirements.

The Model OH-DR1 nozzle has been designed for Domestic and Residential areas only. For areas with higher hazards, almost requiring a higher hazard group classification or areas in which a low hazard group classification is questionable, the Model OH-VSO is the advised solution, as the Model OH-VSO has also been designed for protection of higher hazard groups.
