It is the sizing range of the Multifan family: the \u003ca href=\"https:\/\/www.hydrooasis.com.au\/products\/ac-infinity-multifan-mini\" target=\"_blank\" title=\"AC Infinity Multifan Mini USB Axial Fan\" rel=\"noopener\"\u003eAC Infinity Multifan Mini USB Axial Fan\u003c\/a\u003e covers the micro spaces these frames cannot enter, the \u003ca href=\"https:\/\/www.hydrooasis.com.au\/products\/ac-infinity-multifan-usb-blower\" target=\"_blank\" title=\"AC Infinity Multifan USB Centrifugal Blower\" rel=\"noopener\"\u003eAC Infinity Multifan USB Centrifugal Blower\u003c\/a\u003e handles shelves with no clearance above the gear, and the axial series matches frame to space - an 80 mm unit for a shelf corner, a 140 mm unit for the widest quiet sweep, or a dual set cooling two spots from a single USB port.\u003c\/p\u003e\n\u003cp\u003eEach unit pairs an axial impeller with dual ball bearings rated for a 67,000 hour L10 lifespan, housed in a 2.5 cm (1.0 in) deep frame with a wire guard on both faces and eight detachable anti-vibration silicone feet. The S1 spins an 80 mm blade at 2000 RPM to move 44 m³\/h (26 CFM) at a manufacturer-rated 17 dBA on 1.1 W; the S3 turns a 120 mm blade at 1300 RPM for 88 m³\/h (52 CFM) at 18 dBA; the S4 swings the largest 140 mm blade at 1200 RPM for 97 m³\/h (57 CFM), also at 18 dBA. The dual configurations join two fans with a 76 cm (2.5 ft) cord: the S5 pairs two 80 mm fans for a combined 88 m³\/h (52 CFM), while the S7 pairs two 120 mm fans for a combined 177 m³\/h (104 CFM) at a rated 19 dBA and 2.9 W. Power comes from any 5 V DC USB port rated 500 mA or higher, through a 132 cm (4 ft) cord carrying an inline three-speed controller and a further 69 cm (2 ft) run from controller to fan.\u003c\/p\u003e\n\u003cp\u003eAn extra USB port on each fan body allows up to four fans to share one power source, with chained fans following the controller nearest the supply; the dual S5 and S7 count as two fans each. Every model mounts horizontally or vertically and flips over to switch between intake and exhaust duty, operating anywhere from -18 to 70°C (0 to 158°F) and 35 to 85% relative humidity. These are standalone USB devices with no UIS connectivity, so where a grow space calls for sensor-driven canopy circulation the mains-powered \u003ca href=\"https:\/\/www.hydrooasis.com.au\/products\/ac-infinity-cloudray-s-oscillating-clip-fan\" target=\"_blank\" title=\"AC Infinity Cloudray S Oscillating Axial Clip Fan\" rel=\"noopener\"\u003eAC Infinity Cloudray S Oscillating Axial Clip Fan\u003c\/a\u003e is the step up. Available in S1, S3, S4, S5 and S7 models spanning 44 to 177 m³\/h (26 to 104 CFM). Its dual-fan configurations put moving air on two pieces of equipment at once while drawing no more than 2.9 W from a single USB port.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e USB fans are ineffective in fully sealed enclosures - air must be able to flow in and out of the space through vents or openings. Multifan units are not designed for outdoor use, filter attachment or through-wall mounting, and splicing or hardwiring the USB cords voids the warranty.\u003c\/em\u003e\u003c\/p\u003e","brand":"AC Infinity","offers":[{"title":"S1","offer_id":46844114665630,"sku":"854759004327","price":39.99,"currency_code":"AUD","in_stock":true},{"title":"S3","offer_id":46844114698398,"sku":"854759004310","price":44.99,"currency_code":"AUD","in_stock":true},{"title":"S4","offer_id":46844114731166,"sku":"854759004365","price":49.99,"currency_code":"AUD","in_stock":true},{"title":"S5","offer_id":46844114763934,"sku":"854759004334","price":54.99,"currency_code":"AUD","in_stock":true},{"title":"S7","offer_id":46844114796702,"sku":"854759004341","price":59.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/AC_Infinity_MULTIFAN_S1.png?v=1784690438","url":"https:\/\/www.hydrooasis.com.au\/products\/ac-infinity-multifan-usb-fan","provider":"Hydro Oasis","version":"1.0","type":"link"}
