Manthorpe G700 Circular Soffit Vent - Pack of 50 - Black
The Manthorpe G700 round soffit vent is able to achieve both 10,000 and 25,000mm2/m.
This Manthorpe circular soffit vent can be slotted into the soffit board before installation for new build projects or retro-fitted into existing soffits.
To fit this soffit vent, simply push and twist into a 70mm hole drilled into the soffit board.
The G700 soffit vent has evenly spaced slots that are small enough to stop large insects gaining access into the roof space but wide enough not to be blocked by debris, paint or water droplets.
- For 10,000mm²/m of free airflow the G700 should be fitted at 200mm centres
- For 25,000mm²/m of free airflow the G700 should be fitted at 86mm staggered centres
