The volume of space to be ventilated is estimated and multiplied by the number of air changes per hour and divided by the extraction rates of the roof turbine. The table gives a guide to the number of air changes generally recommended taking into consideration grater air changes due to the nature of the application.

  4. EXAMPLE:

  A specification for a 260m² room with a roof height of 6m with 10 air changes per hour natural ventilation required, manufactured in Aluminium material with Trimmers  would be:

  5. CALCULATION:

Area x Roof Height x Air Changes per Hour / Extraction Rate 260m² x 6m x 10 / 3900 (Extraction rate of the Curvent Pinnacle CPT400) = 4 x Curvent Pinnacle type CPT400 Roof Turbine Ventilators.

  6. SPECIFICATION DESCRIPTION:
