Solar Sub-floor Ventilators

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.  

 

Solar sub-floor ventilator will cure crumbling bricks.

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?
Solar sub-floor ventilator will prevent rotting of floor joists.

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?

3.   Solazone in-line 150mm solar ventilator fan kits. 

Ideal to install with flexible duct or a PVC pipe to direct air right into, or suck from, a specific damp problem area.

Solar sub-floor inline ventilator fan          Solar sub-floor inline ventilator fan inside

  • Direct fresh air to, or draw moist air from, specific problem areas under the floor.
  • More effective and faster for clearing up particularly bad problem areas.
  • Fit the duct, or PVC pipe, onto the fan flange to target the specific moist place.  
  • In the 150 mm fan options, the brushless 20-watt model is quieter than 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.

flexible-ducting

  • 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

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 metal strapping with the duct kits, or it can be purchased locally.

4.    Large flow, 300mm Gable-mount or In-line fans.  

  • Move massive amounts of air into, or out from, a sub-floor area.    Use the SV3000 gable fan models, and a much bigger hole in the wall to really get rid of the damp.
  • These fans require a safety cover, for accident protection.
  • The 300 mm inline fans may be ducted from either or both sides.  (Select the required model)  

Dimensions:

Fan blades diameter: 300mm, Flange outside diameter: 500mm,  housing depth: 200mm.

 

Hugely effective, silently moves more air than any other sub-floor fan, fits 300 mm diameter flexible duct.

Carefully consider the air flow volume and direction if using this bigger volume fan.

For safety, when purchasing the Gable-mount Solar Fan, you will probably need to order at least one Gable Vent Cover to control access to the spinning fan, and possibly another to cover any additional vent hole needing protection from the weather.

These weatherproof vent covers are made from moulded plastic and suit the sub-floor Gable fan.   They can be painted to match the house.   An additional cover may be used to cover a big vent opening at the other end of the house.

Safety cover for the Gable sub-floor ventilation fan

Plastic safety covers are currently unavailable

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.    This extra control can be gained from fitting an adjustable thermostat, which controls the temperature at which the fan starts and stops operating.   Remember that the basic adjustable thermostat measures the air temperature where it is actually located, so don’t install it under the house!
