top range of Home Ventilation Products…

Over a 17 year period we have designed and searched the world for a range of products that are the most advanced, economical, quietest and of the highest quality and manufacturing standards so we can provide the very best to our customers.

We have a range of acoustic low profile mixed-flow-in-line fans that produce low noise when in operation.  They do this through a specifically designed perforated internal skin that directs sound waves produced inside the fan to a layer of sound absorbent material.

Mould thrives in humidity

Mould requires 70-90% humity to trive which is common in the coast regions of Australia.

“This level of humidity not only encourages mould, it is also conducive to the growth and development of dust mites.8 Indoor humidity levels reflect the atmospheric conditions together with moisture created by occupants’ activities within the home which means that any home may be susceptible to mould.”

“Moisture can also enter a home through leakage, condensation in the wall cavity and damp ground conditions under suspended timber floors. This can lead to mould growth in areas that can’t be seen but can still impact on air quality. “
