Circular soffit vents


Circular Soffit Vents can be slotted into the soffit board prior to installation for new build situations or just as easily retro-fitted into existing soffits.
The G700 Circular Soffit Ventilator is designed to be fitted before or after installation of soffit boards. The airflow passage consists of evenly spaced slots specifically sized to prohibit large insects gaining access but wide enough not to be blocked by debris, paint or water droplets.
 
Fitting
 
The G700 Circular Soffit Ventilator (A) should be a “push” fit into a 70mm (2.75”) diameter hole drilled into the soffit board as shown.
 
Airflow
 
2150mm² per Disc Vent  To achieve 10,000mm2/M of free airflow the Disc Vent should be fitted at 200mm centres.
To achieve 25,000mm2/M offered airflow the Disc Vent should be fitted at 86mm staggered centres as shown
