Rotary Turbine Roof Ventilators



The importance of effective natural ventilation of factories of industrial buildings, commercial premises, warehouses, workshops and residential houses is often underestimated during the building design process.

Hot and unventilated buildings create an environment where the occupants can feel lethargic and are unwittingly forced to breathe stale air, or even worse, toxic fumes from the likes of work practice, fork hoist operations and truck exhaust fumes etc

As part of an overall healthy building ventilation strategy, rotary turbine ventilators can at a reasonable cost be installed in either new buildings or retrofitted into existing structures. With models available for residential, commercial and industrial applications, rotary turbine ventilators also assist with the prevention of condensation by extracting condensation-forming air
