Do you want cooling targeted exactly at the hotspot areas in your Data Centre? Airbooster Pro's manually adjustable air transfer grille is designed to just this type of pinpoint accuracy. The vanes are precisely positioned to target locations that require increased cooling. The concentrated air flow goes to work on the targeted areas, reducing overall hot spot problems by also ensuring an adequate supply of cold air is supplied to other areas. In short, the right climate is therefore provided exactly where it's needed most - and without complicated installations and enclosures.

  • Suitable for Data Centres with raised floors
  • Suited to cooling localised HD zones
  • Airflow  up to 2500 m3/h
