The carbon filling is machine-packed for superior compaction, and the compaction maintained by a ring of Acoustafoam expanding compaction foam. The deep carbon bed is confined within concentric mesh cylinders made from rugged perforated Zintec sheet, with end caps also made of Zintec for strength. A machine-washable pre-filter sleeve is provided and secured with elastic silicon bands at either end to prevent dust clogging the filter. Even with its impressive airflow rating, this filter will capture malodorous volatiles.  \u003cbr\u003eKey selling points:  \u003cbr\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eImpressive airflow \u003c\/li\u003e\n\u003cli\u003eExcellent performance – captures malodorous volatiles \u003c\/li\u003e\n\u003cli\u003eMachine-packed premium Australian activated carbon \u003c\/li\u003e\n\u003cli\u003eCompaction maintained by Acoustafoam ring \u003c\/li\u003e\n\u003cli\u003eRugged all-Zintec body \u003c\/li\u003e\n\u003cli\u003eWashable pre-filter sleeve  \u003c\/li\u003e\n\u003c\/ul\u003e \u003cbr\u003eTechnical Specifications:   \u003cbr\u003e\u003cul\u003e\n\u003cli\u003eRated for airflow up to: 3600 m³\/hr \u003c\/li\u003e\n\u003cli\u003eDuct \/ filter neck nominal diameter: 315 mm (12”) \u003c\/li\u003e\n\u003cli\u003eFilter length: 1200 mm (47.25”) \u003c\/li\u003e\n\u003cli\u003eCarbon bed depth: 60mm \u003c\/li\u003e\n\u003cli\u003eCylindrical Zintec perforated mesh: 55% open area \u003c\/li\u003e\n\u003cli\u003eBody material: Zintec zinc-coated steel sheet. \u003c\/li\u003e\n\u003c\/ul\u003e \u003cbr\u003eFAQs:  \u003cbr\u003eQ: How should I choose a filter to match the fan that I shall use? \u003cbr\u003eA: When setting up your ventilation system, of course the first consideration is the diameter. It is simpler to set up if ducting, fan and filter all have the same nominal diameter, although the diameter of fan and filter can vary. If this is the case, it is recommended to use a filter of a slightly larger diameter than the fan, rather than the other way around. Bear in mind that adding ducting and a filter will increase the operating pressure of the system, and consequently the actual flow rate of your fan will be reduced from its free flow rate. As a rule of thumb, choose a filter with a flow rate 20% larger than the fan’s free flow rate. \u003cbr\u003eAlso, remember that all filters work more effectively if the actual air flow is lower than the rated air flow. A filter with a higher rated air flow than the true air flow of the system will work more effectively, for longer. \u003cbr\u003e \u003cbr\u003ePurchase this with…  \u003cbr\u003e08-360-130 - RAM ALUDUCT Low Noise Ducting - 315mm x 5m \u003cbr\u003e08-350-102 - RAM Filter Stand \u003cbr\u003e \u003cbr\u003e \u003cbr\u003e","brand":"RAM - RAPID AIR MOVEMENT","offers":[{"title":"Default Title","offer_id":53420788449623,"sku":"08-350-395","price":217.3,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1003\/2558\/9335\/files\/08-350-395_1.jpg?v=1777302365","url":"https:\/\/hydrohub.org.uk\/products\/ram-airtech-heavy-filter-315-1200-12-4250m-h","provider":"Hydro Hub","version":"1.0","type":"link"}
