These inline sub floor ventilation fans are perfect for massive areas where lengthy lengths of duct is important. A low voltage fan may be put in in a wall and may be enough for small areas and don't require entry to the sub floor. Another option is to run the ducting directly from the dampest a part of the sub-flooring space to the photo voltaic sub-flooring ventilator fan. A properly implemented subfloor air flow system by Doctor Damp will take away stale moisture-laden air by using specially designed pumps and subfloor followers to extract extreme moisture from the subfloor area.
