Warm, stale air stalls transpiration, showing up as slow growth, poor nutrient uptake and airy buds late in flower. An EC fan matches extraction to the room and cuts the draw at once.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize it:\u003c\/strong\u003e exchange the room volume roughly \u003cstrong\u003eonce per minute\u003c\/strong\u003e, then add headroom for filter and ducting resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHang it\u003c\/strong\u003e from the supplied attachments rather than hard-mounting, so vibration stays out of the frame\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrder the run:\u003c\/strong\u003e filter, fan, then acoustic ducting out\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial in the speed\u003c\/strong\u003e on the supplied controller until temperature and humidity settle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRun continuously\u003c\/strong\u003e through lights-on and lights-off to keep the environment stable\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e 150mm (6\"), 200mm (8\"), 250mm (10\"), 315mm (12\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow:\u003c\/strong\u003e 594 m³\/h (150mm), 1,205 m³\/h (200mm), 1,808 m³\/h (250mm), 2,987 m³\/h (315mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 40W \/ 75W \/ 150W \/ 320W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Speed:\u003c\/strong\u003e 5,000 RPM \/ 3,800 RPM \/ 3,200 RPM \/ 3,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNoise:\u003c\/strong\u003e 50 dBA \/ 51 dBA \/ 55 dBA \/ 68 dBA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type:\u003c\/strong\u003e EC, speed controllable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 220-240V, 50-60Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 600 x 295 x 350mm \/ 775 x 365 x 370mm \/ 935 x 420 x 430mm \/ 1010 x 470 x 490mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e Variable speed controller, power lead, hanging attachments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 2 years manufacturer’s warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Mammoth","offers":[{"title":"6\"","offer_id":53445708677386,"sku":null,"price":247.95,"currency_code":"GBP","in_stock":true},{"title":"8\"","offer_id":53445708710154,"sku":null,"price":301.95,"currency_code":"GBP","in_stock":true},{"title":"10\"","offer_id":53445708742922,"sku":null,"price":385.95,"currency_code":"GBP","in_stock":true},{"title":"12\"","offer_id":53445708775690,"sku":null,"price":579.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/mammoth_s-max_ec_fan_150mm_withlogo_1.jpg?v=1785325051","url":"https:\/\/hydrocropshop.co.uk\/products\/mammoth-s-max-pro-ec-fans","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
