Choosing a filter rated well above the fan's real flow keeps air moving through the grow room and gives the carbon time to do its job, which helps keep conditions steady for healthy plant growth.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize it to the fan:\u003c\/strong\u003e choose a filter rated around 20% above the fan's free-air flow; filters work better and last longer below their rated airflow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatch the diameters:\u003c\/strong\u003e ideally filter, fan and ducting share one size; if not, use a filter slightly larger than the fan rather than smaller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit it:\u003c\/strong\u003e hang it horizontally or stand it upright on a filter stand, and duct it to the fan inlet with clamps.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLook after it:\u003c\/strong\u003e machine-wash the pre-filter sleeve when dusty and refit it once dry.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e150\/660 (6\"):\u003c\/strong\u003e 150mm neck, 660mm (26\") long, rated to 1150 m³\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e200\/660 (8\"):\u003c\/strong\u003e 200mm neck, 660mm (26\") long, rated to 1350 m³\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbon bed depth:\u003c\/strong\u003e 50mm, premium Australian activated carbon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMesh:\u003c\/strong\u003e perforated Zintec cylinders, 55% open area\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody:\u003c\/strong\u003e Zintec zinc-coated steel sheet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-filter:\u003c\/strong\u003e machine-washable sleeve with silicone bands\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"RAM","offers":[{"title":"6\" 150x660 - 1150m3\/hr","offer_id":53803838374154,"sku":"ENV-RAMX-011-01","price":121.95,"currency_code":"GBP","in_stock":true},{"title":"8\" 200x660 - 1350m3\/hr","offer_id":53803838406922,"sku":"ENV-RAMX-011-02","price":151.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/ram-airtech-midi-carbon-filter-1.jpg?v=1790229832","url":"https:\/\/hydrocropshop.co.uk\/products\/ram-airtech-midi-carbon-filter","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
