Cool Stream Ventilation Systems designs, manufactures and installs extraction canopies, kitchen ventilation, air conditioning and filtration — manufactured at our own works and installed across the UK.

Today's buildings are well insulated and tightly sealed, which means they're less naturally ventilated. Replacing stuffy, stale air with fresh, tempered air is essential to the health and wellbeing of everyone inside. Cool Stream Ventilation installs systems that clear the hot, stuffy conditions created by kitchens, plant and equipment — removing airborne contaminants and helping create a genuinely productive, comfortable environment.
