• The Solar Whiz attracts in up to date, dry air by way of wall vents and attracts it via the sub ground space all through the damp earth, efficiently drawing out the moisture and venting it exterior the sub flooring space.
• Special imported high moisture resistant PFC ducts are used on account of they have excessive sturdiness and can last the longest in damp underfloor environments.

There are many alternative kinds of sub flooring ventilation choices, the commonest sub ground air circulate methodology is the air extraction unit which effectively extract moisture from the beneath flooring. the unfavorable pressure created by the sub floor fan ends in alternative air being drawn into the sub ground space by the use of vent and totally different gaps and openings into the sub flooring. Victorian Building Regulations designate Melbourne to be in a ‘Zone three’ local weather space, meaning requirements of subfloor ventilation to be 6-10 air modifications per hour. This implies that all air throughout the subfloor have to be removed and changed by fresh air 6-10 occasions per hour.
