Force 4 Solarvent 300S

Solar powered vents keep your boat automatically vented, silently and with no running costs.

The stainless steel Solar Vent 300 works during daylight hours and incorporates an internal rechargeable battery, which charges up during the day to give up to 3 hours ventilation during the night.

The unit features 3 switches - on/off, in/out and boost. The boost switch allows you to operate the ventilator at night or during overcast conditions.

The vent can also be closed to make it waterproof during severe weather conditions by simply twisting and pulling the fan mechanism.

  • Easy to install – wire free
  • Helps reduce condensation
  • Stainless steel cowl
  • Auto/Off switch • Air In/Out – up to 25 cubic metres of air per hour
  • Internal 1.2V 600mAh NiMh AAA rechargeable battery (user replaceable)
  • Cut out size: 115mm
  • Overall Diameter: 220mm
  • Suitable for installation in glassfibre, wood, metal, polycarbonate, glass or similar materials
  • Supplied with fixing ring and foam gasket (requires 6 x No.8 screws, not included)

I need 2 of these but, due to the make up of the interior of my boat, I would like to see an image of the part that is inserted into the deck of the boat (cutout area). Can you send any further information such as "how do I switch the unit on/off/reverse etc? Thanks Glyn Wright

Can this vent be mounted on a vertical surface (wall). or is it only on a horizontal roof surface? Helena Griffiths
There is no reason this can't be mounted on a vertical surface. However, we can't guarantee how watertight it would be.
How do i secure it to a fibre glass boat? The manual does not specify. Also is a foam gasket included? Tom
These can only be mounted in Wood, Glass, Metal, Polycarbonate or similar materials. This does state that the Foam Gasket is included. 30.10.20
Can this vent be fully closed from the inside to be watertight in very wet weather? James Sedgwick
The SmartVent is supplied in the open position, however you can close the SmartVent to waterproof the product in severe weather conditions. 20/01/22
