Subfloor Ventilation

Underfloor Ventilation in Melbourne

Locked House Ventilation Systems is the trusted name for underfloor ventilation system in Melbourne. Highly effective, yet silent, our subfloor ventilation systems will provide the perfect ventilation for your home.


What is sub floor ventilation?

Does your house have a musty smell? Do you have a problem with rising damp?

That is where our underfloor home ventilation is the solution to these issues. Subfloor ventilation systems create an outlet for stagnant air to circulate allowing it to escape instead of seeping into your home. Without the appropriate system in place it will become fetid leading to ideal conditions for the growth of mould, damp and wood rot.

On average, Melbourne’s air sits at 56% relative humidity; this creates a moist environment under our homes leading to subfloor moister issues (and if you’re unlucky if roof issues, needing roof ventilation). Our underfloor ventilation system create 24 air changes per day keeping flooring timbers at 14% moisture.

This is enough to:

- Dry and settle damp swollen floor boards
- Reduce/eliminate condensation
- Prevent rot and mould growth
- Stop irritating airborne allergens
- Prevent bad smells throughout your home

We have developed three basic ways of drying damp subfloors:


The SILENT SAHARA SUBFLOOR FAN and ducting system.
150mm size air flow 530 cubic meters per hour
200mm size air flow 900 cubic meters per hour

Most customers cannot determine whether or not their Silent Sahara Fan is operating unless they go outside to the exhaust grille. Quiet and powerful, a Silent Sahara Subfloor desert can be created under your home. Designed for long duct (pipe) runs that exhaust damp air from areas that other underfloor ventilation fans cannot reach.

Budget 14 volt systems when less performance is required.


Best for brick veneer subfloors, ideally with four or more bricks below floor level.

EDMONDS ECOFAN provides air flow of up to 730 cubic meters per hour. Locked House Ventilation Systems helped develop the original Ecofan 17 years ago and now the new model has everything you’ll need in this type of fan. The new fan has 24 volts, 30watts, 3 speeds and low noise levels. A second Ecofan can be reversed to supply air on the opposite wall

• EWL external (boxed) 150mm exhaust fan

• Option for long ducting systems fitted to reach damp areas

• Air flow is 440 cubic meters per hour

• 240 volts


Our subfloor ventilation systems use a 150mm pipe (externally or hidden internally) to draw damp subfloor air up and exhaust it to the outside via a 250mm wind powered Supavent. Air flow is 80 to 120 cubic meters per hour and a fan can be added to the system boosting flow to 200 cubic meters.


Fresh drying air entering the subfloor at the necessary places, in the required volume, is insufficient in damp houses. Special reverse louver brick replacement grilles capture 90% of passing wind air currents.

As part of our subfloor ventilation services, we also install a range of grilles including Edwardian and Victorian.

An electrical 24 hour timer automatically controls the drying sessions, and can be reduced or increased seasonally.

We use an A grade quality electrician to do all electrical installations.
