SW2100 RAF Gable kit with louvre grill for subfloor drying
Solar Sub floor Fans system with louvre grill for self install only
Solar powered extractor fans offer a couple of obvious advantages over the traditional mains powered and timer operated systems when installing under floor ventilation fans for sub-floor ventilation:
- The systems only operate during sunny conditions – ensuring that the replacement air generally is quite dry and therefore contributes to keeping the sub floor dry
- Solar powered under floor ventilation fans cost nothing to operate.
