What makes the Multi Storey model different?
It's a Positive Input Ventilation (PIV) unit with a built-in 500 W heater and a fire damper, sized for whole-house condensation and mould control in larger, multi-storey homes up to 200 m².
What does the fire damper do?
It can be wired into a fire alarm with an integral relay to cut power to the unit if smoke is detected. It's supplied with intumescent fire-protective ducting and a fire-stopping diffuser rated for up to one hour.
Will it cure condensation and mould in a whole house?
Yes — variable speed control lets it effectively ventilate a property up to 200 m², lowering humidity throughout to cure condensation and mould at the cause.
Does it have any special modes?
Yes — an automatic summer shut-off stops warm air returning into the home, and a Radon mode runs the unit continuously to protect residents in properties with high radon gas levels.
How much air does it move and what does it filter?
It's fully adjustable between 11 and 60 l/s (up to 216 m³/h) and uses a G4 filter with an F7 upgrade option for PM2.5 filtration.
What's the warranty?
It carries a 5-year manufacturer's warranty and should be installed by a competent person.
