Most average homes land on one 200 mm fan or two 150 mm fans.\u003c\/p\u003e\n\u003cp\u003eLayout matters as much as the number. Extract from the dampest side — usually the shaded elevation or the one against a retaining wall — and let fresh air draw in through existing vents on the opposite side. Two smaller fans at opposite ends often beat one larger fan in the middle, because cross-flow sweeps the whole void. Between two sizes, take the bigger one and run it slower: quieter, less power, longer life.

The 150 mm kit is $386.95 against $417.95 for the fan, ducting and clamps separately; the 200 mm kit is $499.95 against $549.00; the VIND kit is $349.95 against $379.90.

Every fan ships with an Australian three-pin plug and a lead, so if there is a suitable outlet within reach the work is carpentry — cutting the opening, running the duct, weathering the outside and hanging the fan on its straps. Running a new circuit or outlet, or hard-wiring a unit, is licensed electrical work in Australia. Before going under the house, be aware that older subfloors can contain asbestos and live wiring, and a low crawl space carries a real confined-space risk.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05rem;font-weight:700;color:#222;margin:22px 0 6px;\"\u003eWill a kit fix rising damp?\u003c\/h3\u003e\n\u003cp\u003eNo. A kit exchanges humid air for drier outside air, which is the right fix for musty smells, mould on the underside of floorboards and timber decay. It does nothing about water arriving — standing water, a blocked or badly graded drain, a leaking pipe, an air conditioner condensate line or a failed damp course are building problems and need fixing first. If the subfloor is visibly wet rather than merely humid, sort the water before ordering a fan.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05rem;font-weight:700;color:#222;margin:22px 0 6px;\"\u003eWhat if I only need the fan?\u003c\/h3\u003e\n\u003cp\u003eThen buy the fan on its own — the whole \u003ca href=\"\/collections\/subfloor-ventilation\" style=\"color:#C0392B;\"\u003esubfloor and underfloor ventilation range\u003c\/a\u003e is there, including the wall-mounted \u003ca href=\"\/products\/ac-infinity-airtitan-t8-crawl-space-exhaust-fan\" style=\"color:#C0392B;\"\u003eAIRTITAN T8\u003c\/a\u003e for crawl spaces where a ducted install is impractical.

Set a humidity threshold and the fan starts when the subfloor crosses it and stops when it drops back, so it runs the hours that achieve something and stays silent the rest of the time.

As a working guide, work out your subfloor volume (floor area × average ground-to-bearer clearance), multiply by your target air changes per hour, then divide by roughly 0.6 to allow for duct losses.

Most average homes land on one 200 mm fan or two 150 mm fans. What matters as much as the number is the layout — extract from the dampest side and let fresh air draw in through existing vents on the opposite side. Do not put intake and exhaust close together or the fan short-circuits and recycles the same air.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05rem;font-weight:700;color:#222;margin:22px 0 6px;\"\u003eCan I install this myself?\u003c\/h3\u003e\n\u003cp\u003eFor most houses, yes.

Running a \u003cem\u003enew\u003c\/em\u003e circuit or outlet, or hard-wiring the unit, is licensed electrical work in Australia and is not a DIY job.

Three things make a subfloor fan audible upstairs — running it at full speed, bolting it hard to a joist so vibration transfers into the floor, and bare foil ducting carrying noise along the run.

For bathroom use it must be part of a suitably designed ducted system, must not sit inside a shower enclosure or anywhere exposed to direct spray, and any fixed wiring is a licensed electrician’s work.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05rem;font-weight:700;color:#222;margin:22px 0 6px;\"\u003eIs this genuine AC Infinity stock with an Australian warranty?\u003c\/h3\u003e\n\u003cp\u003eYes.

Set a humidity threshold and the fan starts when the subfloor crosses it and stops when it drops back, so it runs the hours that achieve something and stays silent the rest of the time.

Bends and length both cost airflow, so a long run wants the bigger fan even when floor area alone would not say so.

Most average homes land on one 200 mm fan or two 150 mm fans. What matters as much as the number is the layout — extract from the dampest side and let fresh air draw in through existing vents on the opposite side. Do not put intake and exhaust close together or the fan short-circuits and recycles the same air.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05rem;font-weight:700;color:#222;margin:22px 0 6px;\"\u003eCan I install this myself?\u003c\/h3\u003e\n\u003cp\u003eFor most houses, yes. The fan ships with an Australian three-pin plug and a 2.44 m lead, so if there is a suitable outlet within reach the work is carpentry — cutting the opening, running the duct, weathering the outside and hanging the fan. Running a \u003cem\u003enew\u003c\/em\u003e circuit or outlet, or hard-wiring the unit, is licensed electrical work in Australia and is not a DIY job. Before you go under the house: older subfloors can contain asbestos and live wiring, and a low crawl space is a genuine confined-space risk.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05rem;font-weight:700;color:#222;margin:22px 0 6px;\"\u003eWill I hear it in the rooms above?\u003c\/h3\u003e\n\u003cp\u003eNot if it is installed properly. Three things make a subfloor fan audible upstairs — running it at full speed, bolting it hard to a joist so vibration transfers into the floor, and bare foil ducting carrying noise along the run. Hang the fan on the supplied straps rather than screwing it to timber, run it on a humidity trigger at a moderate speed, and the 38 dBA rating is a ceiling you will rarely reach — a 200 mm fan at level 4 is quieter than a 150 mm fan at level 9 doing the same work.

It does not fix water arriving. Standing water, a blocked or badly graded drain, a leaking pipe, an air conditioner condensate line or a failed damp course are building problems and need fixing as building problems first.

The same fan, controller and ducting work in a roof space or attic on a temperature trigger, in a garage or workshop, or as part of a properly designed ducted bathroom exhaust system.

Think of the acoustic metre as the quiet section at the noisy end, not the whole duct.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05rem;font-weight:700;color:#222;margin:22px 0 6px;\"\u003e200 mm or 150 mm?\u003c\/h3\u003e\n\u003cp\u003e200 mm for a larger subfloor, a long run, or a duct that has to weave around piers and services. The \u003ca href=\"\/products\/vind-150mm-silenced-inline-fan-w-manual-controller\" style=\"color:#C0392B;\"\u003e150 mm fan\u003c\/a\u003e handles a smaller footprint with a short, direct run and takes up far less space. Send us the dimensions and how the duct has to travel if you are close to the line — an oversized fan turned down is quieter than a small one flat out.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05rem;font-weight:700;color:#222;margin:22px 0 6px;\"\u003eWill it fit where I want to put it?\u003c\/h3\u003e\n\u003cp\u003eCheck first. The fan alone is 689 mm long, Ø290 mm across and 7.3 kg — considerably bigger than a bare 200 mm fan, because the acoustic chamber is the whole point. Measure the cavity, make sure the mounting will take the weight, and leave room for the duct to leave the fan without an immediate hard bend.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05rem;font-weight:700;color:#222;margin:22px 0 6px;\"\u003eDo I need an electrician?\u003c\/h3\u003e\n\u003cp\u003eNot for the fan itself — it comes with a 3 m power cord and a standard plug. If you want it hard-wired, on a dedicated circuit, or fed from a point that does not exist yet, that part is an electrician's job.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05rem;font-weight:700;color:#222;margin:22px 0 6px;\"\u003eCan it run continuously?\u003c\/h3\u003e\n\u003cp\u003eYes, and that is the intent. EC motors are built for long runtimes, and 90 W for this much airflow makes round-the-clock ventilation reasonable rather than expensive.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"VIND","offers":[{"title":"Default Title","offer_id":52941003981114,"sku":"VINDSFK200","price":349.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1567\/1791\/files\/silenced-subfloor-fan-kit-200-mm-vind-4788519.jpg?v=1769547787"}],"url":"https:\/\/www.quickbloomlights.com.au\/collections\/subfloor-ventilation-kits.oembed","provider":"Quick Bloom Lights","version":"1.0","type":"link"}
