This system describes CNA’s EXH range of ventilation fans. Whereby a CONE type fan is designed for a much higher air flow volume, wider cyclone radius and higher discharge pressure (longer throw distance). It can target and move air in a longer distance effectively by using the same or lesser amount of electricity a conventional fan utilises.

Conventional Type Fan Inefficient and scattered air discharge. Air discharge is not concentrated, causing air turbulence.	CONE Type Axial Fan Efficient and even air discharge. Air discharged is concentrated towards the intended direction.

This system drives airflow towards  a single direction, approximately 60 to 80 feet with minimum air turbulence. It encourages constant airflow, creating a comfortable environment.

This type of installation method is generally used in warehouse corridor, production line workstation and locations that does not have relatively high ambient temperature.
