Protect your most valuable asset,
your home, with Envirofan
sub-floor ventilation solutions.


"I recently purchased goods through Envirofan. I'm normally quite hesitant to purchase goods via email using EFT (electronic fund transfer), but with Christine's help, I felt very at ease. My goods arrived promptly and Christine was there every step of the way to answer my questions. I would have no hesitations in recommending anyone that wants to do business with Envirofan this way. They are a trustworthy company as my experience has shown," Liz C., Sydney
"I have used your Envirofan Quad Fans... they were excellent. Your sub-floor Quad Fan, compared to my neighbours $6,000 alternative system, was far more effective and we have raved about your fan from day one to everyone who has sub-floor problems," W. Chong, Sydney

Stop dampness in its tracks! Reverse the cycle of mould and heat build up as you protect your health and your home.

How does fan-forced sub-floor ventilation
shield you and your family's health?

If humidity is entrapped in the sub-floor this can penetrate through the floor into your home. Relative humidity levels above sixty per cent inside the habitable area will allow for mould growth. Once this cycle starts, you put yourself and your family at risk of allergic reactions, infections or toxic responses. Symptoms include eye irritation, respiratory problems (such as wheezing, coughing or difficulty breathing), skin irritation, headaches, fatigue, aching joints, vomiting, nose or throat irritation and nasal or sinus congestion. If your condition is pre-existing, such as bronchitis and asthma, this will only make the condition worse.

A dry sub-floor is also a deterrent for termites. This fact is outlined in the ‘Termite Inspection Report' in accordance with AS 3660.

A damp sub-floor can affect the building by changing the cell structure in timber. By the timber expanding this will make floors bounce, lead to bending, warping and ultimately dry rot whereby the floor and its supporting structure fails. Solving a termite infestation or replacing supporting materials in your home can be a very inconvenient and a costly exercise.

Why choose Envirofan for your sub-floor ventilation solution?

We are an Australian company with over 40 years of experience. In the 1970's Solarfan, was the first company to introduce fan-forced sub-floor ventilation systems in the brick and terracotta vent size. UniSearch was commissioned to test the product before its release to the public. The results of the R&D (research and development) made Solarfan to be the quietest sub-floor ventilation system in the marketplace. The brick size ventilation system proves to be the most versatile and effective with its ventilation properties, especially where sub-floors areas have a reduced clearance to the internal floor and external elevated ground levels which impinge on internal sub-floor spaces.
Finally being a 12 volt system the sub-floor ventilation system is economical to run
even on the 12v low voltage electric option.

In 2001 Envirofan took over from Solarfan's legacy and introduced the quad-fan system (EF10-4) — 'EF' meaning Envirofan.

Envirofan's cutting edge design principle is to maximise sub-floor ventilation without obstructions. In ninety eight per cent of cases our objective is to minimise the use of flexible ducting and in-line fan systems where the path of air is disrupted. We recommend low-voltage or solar-powered fan-forced systems to provide a sub-floor ventilation solution with the least alteration to your home by strategically retrofitting existing passive vents. The carbon footprint of our product is virtually non-existent, unlike 240v systems.

Envirofan is tried and tested with unparalleled success, facilitated by knowledge and experience. Beware of opportunistic ventilation or pest management companies who would jump at the chance to use your home to test their product! Remember, if it's not Envirofan, it isn't one!
