High Capacity Ventilation
IVR Group's range of high capacity ridge and slope ventilators are engineered to take maximum advantage of natural stack action – the product of temperature and height. Both the Vangard® and Hotspur® Series ventilators are designed and engineered to ensure low pressure regions, which give rise to the suction effect and assist ventilation, exist regardless of wind direction – meaning high volume flow rates perfect for mining and infrastructure projects.
Weather
All IVR Group ventilators have been tested and proven to AS2428.1 (Rain) and AS2428.2 (Wind) for weather-tightness and have been engineered to operate in cyclonic conditions.
High flow water and debris drainage systems are incorporated within the ventilators and result in all wind borne matter and rain being effectively carried to the outside of the ventilator while retaining effective unimpeded natural ventilation.
Typical Use
- Processing facilities and washeries
- Medium-Large Workshops
- Water treatment and desalination plants
- Warehousing and Chemical Storage
