Solazone solar-powered sub-floor ventilator fans
Remove dampness under floors permanently, and end your moisture problems for good, with a solar-powered sub-floor ventilator
- Solazone sub-floor ventilators are reliable, quiet, and fully automatic
- Run every dry day, costing nothing at all to run
- Very easy to install.
- No electrician or tradesman is required.
You may have a serious damp problem, even before you can smell it, with corrosion creeping up masonry walls, and floor timbers swelling and rotting.
Solve this problem permanently by installing a Solazone solar subfloor ventilator.
Sub-floor ventilators will prevent crumbling of bricks and foundations.
Checklist:
- Is it damp under the house?
- Are the foundations damaged?
- Do floorboards move or squeak from rotting timber?
- Are you encouraging termites?
- Is there an unpleasant smell from dampness under floor?
Sub-floor ventilators will prevent rotting of floor joists.
- A simple remedy for damp and smelly underfloor areas.
- A permanent solution – once installed, you have ongoing protection.
- No more smells, rotting timber, or flaking paint.
- No running cost at all, and no intrusive noise.
- No sprays, no poisons.
Five common problems eliminated by our effective solar-powered sub-floor ventilators:-
• Horrible, mouldy smell.
• Rotting floorboards & stumps.
• Damage to internal walls & paintwork.
• Crumbling brickwork and foundations.
• Breeding ground for termites, white ants & borers.
and the sixth is far more serious – permanent bad health, from breathing in harmful mould spores by you and your family.
Solar sub-floor ventilators pass warmer, drier, outside air through damp sub-floor areas, to remove the moisture that causes damage.
- The fan operates during daylight hours only, when the fresh air is warmer and drier, rapidly dehumidifying under the floor.
- The dampness under the floor is completely removed, so long as any new water flow is stopped.
- Once dried out, the problem is gone forever.
- Why pay to operate the fan, when the sun removes your problem for free?

Solazone in-line 150mm solar ventilator fan kits
- Can be installed with 150mm flexible duct or PVC pipe to direct air right into, or suck from, a specific damp problem area.
- Great for directing fresh air to, or drawing moist air from, specific problem areas under the floor.
- Can be more effective and faster for clearing up bad problem areas.
- Fit the duct, or PVC pipe, onto the fan flange to target the specific moist place.
- The brushless 20-watt solar fan is more powerful and quieter than the previous 16-watt model fans. They are the same physical size.
- Generally, there is more friction loss in a duct on the downstream side of the fan, compared with that on the suction side. So if possible, it is better to draw the air towards the fan through the duct, rather than to push it for long distances through a duct after the fan.
Insulated flexible ducting lasts longer
- The 150 mm 20-watt brushless DC fan, runs from a 20-watt solar panel. We use specially matched low-voltage solar panels to protect the fan.
- Mount the solar panel on a nearby sunny roof, or wall, and wire it directly back to the fan.
- You can add a DC switch or a thermostat to control the fan’s operation times. In practice, usually, it is not necessary to switch the fan off though.
- The more sun the solar panel gets, the better will be the performance of the system. Avoid shady positions.
- These fans have metal 150 mm flanges fitted to inlet and outlet, for easy fitting to flexible ducting. Just use cable ties or duct tape to hold the duct in place.
- PVC waste pipe also fits straight onto the fan flanges and can make it easier to dry out inaccessible places. Avoid getting mud or dust inside the PVC pipe.
Sub-floor duct fittings are available
- Metal elbows, Y-pieces, check valves, and boosting fans, are available, to make up your own customised ventilation system.
- In practice, the fewer fittings you use, the more effective the ventilation.
- To dry out really wet, damp, or cold areas, it can be beneficial to pre-heat incoming air.
- Heated, dehumidified air, blown directly into the damp sub-floor space can dry it out better and faster.

To effectively ventilate a large moist sub-floor area, ducting outside fresh air into the center of the building may be helpful so that the moist air can be vented out equally through existing vents located on all sides of the house. Another option is to run ducting directly from the dampest part of the sub-floor area to the solar sub-floor ventilator fan for extraction to the outside.
We recommend the ducting be suspended from the floor joists to keep it off the ground, We include suitable flexible strapping with the duct kits, or it can be purchased locally.

Important Note:
Give some thought to airflow direction under the house. Use the solar sub-floor ventilator to provide a cross-flow where fresh air is drawn in at one side, and the damp air is expelled from the other. Consider whether you need to make extra openings to assist in this cross flow of air. Air will always take the shortest path. To ensure all the sub-floor space is ventilated, you may even need to cover a couple of nearby vents.
In almost all cases it is best to run solar sub-floor ventilators directly from the solar panel, however in rare cases of extreme damp, it may be preferred to operate the fan via a thermostat, so that only warm air is pumped in.
