Altura Series® Chevron Vertical Louvres

PERFORMANCE DATA

Altura Series®145 is an extruded aluminium 62.5mm pitch by 145mm deep vertical chevron Louvre that provides 60% Free Open Area, Class 1 for Aerodynamics and 95% effective Class C rain defence. Designed with high performance in mind, the Altura Series has been created for commercial plant room enclosures where maximum airflow, good rain defence and zero vision are crucial. This high performance vertical louvre is an excellent lighter weight alternative to the Altura 300 that also provides Class 1 aerodynamics, zero vision screening and a contemporary clean line aesthetic.

Rain Defence Tested as AS/NZS 4740:2000

Rain penetration analysis is tested to AS/NZS 4740:2000 and was conducted at a constant rain flow rate with ventilation rates ranging from 0.5m3/s to 3.5 m3/s. The results concluded that the Altura Series® 145 Louvre’s average rain penetration effectiveness at core velocities from 0 to 3.5m/s was 95% effective achieving a Class C rating.

Rain Defence Tested as AS/NZS 4740:2000

The aerodynamics and discharge coefficient analysis was conducted to AS/NZS 4740:2000 with the ventilation rate ranging from 0.4m/s to 3.4m/s. Table 2 summarizes the ventilator’s aerodynamic performance at different face velocities. The Altura Series® 145 louvre performance resulted in an average discharge coefficient of the ventilator was 0.714 and the effective aerodynamic area was 0.31mÇ with Class 1 performance rating.
