Martin and his staff have at all times been so useful and offer great after sales service. They are trustworthy and trustworthy which could be very uncommon today.

For sub floor air flow, we recommend aiming for between 6 and 10 air changes an hour, but it depends on the severity of the problem. If there may be plenty of moisture underneath the home, you will need a fan with a higher extraction rate. Use our calculator to work out the capability of the fan you need. Schematic circulate diagram of calculation procedure showing transformation from cooling load calculated for an overhead mixing system right into a UFAD cooling load, after which divided between the provision plenum, zone (room), and return plenum. Robust detailing for sub-ground air flow gives a property the best start in the fight towards moisture, damp, dangerous gases and even flooding.
