The VIND 200 mm Silenced Inline Fan is the big one in our own range — 995 m³/h (276 L/s) of airflow from a fan measured at 47 dB. An EC motor with PWM speed control is suspended on vibration-damping springs inside a fully insulated 40–50 mm acoustic chamber, driving a mixed-flow impeller that holds 656 Pa of static pressure through long duct runs, filters and tight cavities. A manual speed controller and a 3 m power cord are included, so it runs from the moment it is plugged in.
Volume without the noise that usually comes with it
Moving close to a thousand cubic metres an hour is normally an exercise in noise management — a big fan, then a silencer, then insulated duct, then someone complaining anyway. The VIND 200 puts the treatment inside the fan. The motor is suspended on internal springs so mechanical vibration never reaches the shell, and the body itself is a 40–50 mm high-density acoustic chamber absorbing motor noise and airflow rush together.
Under a floor or above a ceiling, the complaint is almost never airflow hiss — it is low-frequency vibration passing into joists and turning the structure into a soundboard. Isolating the motor is what stops that before it starts, which is why a 47 dB rating reads quieter in a house than the number alone suggests.
Built for the difficult run
Airflow figures are measured with nothing attached to the fan. Add fifteen metres of duct, three bends around piers and a filter, and a fan chosen on its flow rating alone will disappoint. The mixed-flow impeller here is built for static pressure — 656 Pa — and that is the number that decides how much of the 995 m³/h actually arrives at the far end.
It does that on 90 W. For a fan this size, running continuously, that is what keeps whole-house or large-subfloor ventilation a sensible thing to leave switched on.
Manual control in the box, automation when you want it
The included manual PWM controller gives stepless speed adjustment out of the box — no app, no pairing, no account to create. Set it and leave it.
To have the fan decide for itself, the VIND Temperature & Humidity Controller (sold separately) takes its place, adding independent temperature and humidity thresholds, auto and timer modes, and alarms — still direct-wired, still nothing to pair.

FAQ
Is the 200 mm overkill for my subfloor?
Sometimes, and we would rather say so. The 150 mm handles a smaller footprint with a short, direct duct run perfectly well and takes up far less space. Choose the 200 mm for a larger subfloor, a long run, or where the duct has to weave around piers and services on its way out — length and bends cost airflow, so a difficult run wants the bigger fan even when floor area alone would not say so. An oversized fan turned down is quieter than a small one flat out, so erring upward is rarely the wrong call.
How does the airflow compare with a ceiling or bathroom exhaust fan?
Installers rate exhaust fans in m³/h or L/s. The VIND 200 moves up to 995 m³/h (276 L/s) at full speed. For comparison, the National Construction Code minimum for a bathroom or toilet is 25 L/s (90 m³/h), and 40 L/s (144 m³/h) for a kitchen or laundry, discharged outdoors rather than into the roof space. Real airflow drops with every metre of duct, bend and grille, which is where the 656 Pa static pressure rating matters. Check the requirements for your job with your installer.
Can I use a 200 mm fan in a bathroom?
Most people use the 150 mm for a bathroom, or the 100 mm for smaller rooms such as ensuites and toilets. The larger the fan, the quieter it is for the same airflow, because it can run slower. What suits your job also depends on the space in the ceiling, the duct route and how much noise you can live with, so if you are unsure, send us the details and we will help. Do not install the fan, controller or power connection directly over a shower or bath, or anywhere it can get water spray.
Will it fit where I want to put it?
Check before you order. It is 689 mm end to end, Ø290 mm across the body and 7.3 kg — substantially bigger and heavier than a bare 200 mm fan, because the acoustic chamber is the whole point of it. In a tight roof space or between joists, measure the cavity, confirm the mounting can take the weight, and leave room for the duct to leave the fan without an immediate hard bend.
Is 47 dB loud?
That is the lab figure at full speed, and most installs never run flat out — turning it down brings it below that. The more useful point is that what carries through a floor is low-frequency vibration rather than airflow noise, and the spring-mounted motor plus insulated body target exactly that. A bare fan with the same dB rating on paper will be far more noticeable in a house.
Does the included controller do temperature and humidity?
No. The box contains a manual PWM speed controller — set a speed, it holds it. Temperature and humidity automation comes from the separate VIND Temperature & Humidity Controller, which takes the place of the manual one rather than working alongside it.
Can it run continuously?
Yes. EC motors are built for long runtimes, and 90 W for this much airflow is what makes leaving it on around the clock reasonable rather than expensive.
Will it pull through a carbon filter?
Yes — 656 Pa of static pressure is the figure that matters for a filtered setup, and it is ample for a 200 mm filter with a sensible length of duct behind it. Expect the delivered airflow to sit below the free-air 995 m³/h; that is true of every fan, which is why static pressure is the number worth comparing.
Does it come with hangers?
No — hangers and ratchet straps are not included. Given the 7.3 kg weight, use mounting rated for it rather than the lightest rope ratchet in the drawer.
