Ground under house retains moisture, sub-floor fans required,up to 40cm diameter, to fit into two spaces one of which is 63cmx76cm and the other is larger. To ventilate and keep underfloor area dry
have had (larger-sized) underfloor/sub-floor fans before but they no longer work,need replacing.Am looking for similar-sized fans
