{"product_id":"ram-combi-duct-lightproof-ducting-102mm-x-5m","title":"RAM Combi-Duct Lightproof Ducting - 102mm x 5m","description":"\u003cp\u003eA 4-layer multi-laminated ducting with an encapsulated high tensile steel wire helix which holds the open round shape of the duct to give less drag than competitor products, and thus less noise and less pressure drop in service. The aluminium and polyester inner layers minimise noise, while the tough black PVC copolymer outer acts as a vapour and light barrier and improved airtightness while remaining flexible. Totally plant safe. Supplied individually boxed in a 5m length. In the event of a fire, RAM Combi-Duct will emit no toxic gases.  \u003cbr\u003e\u003cstrong\u003eKey selling points: \u003c\/strong\u003e\u003cstrong\u003e \u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDucting holds its open round shape in all conditions \u003c\/li\u003e\n\u003cli\u003eLightproof, low-noise and plant safe \u003c\/li\u003e\n\u003cli\u003eFits to round inlet\/outlet spigots of fans, filters or junctions \u003c\/li\u003e\n\u003cli\u003eEasily cut to length without special tools \u003c\/li\u003e\n\u003cli\u003eSeal joints with standard clamps or duct tape \u003c\/li\u003e\n\u003cli\u003eFire resistant – will not emit toxic gases in case of fire \u003c\/li\u003e\n\u003cli\u003eNoncorrosive to common metals \u003c\/li\u003e\n\u003c\/ul\u003e \u003cbr\u003e\u003cstrong\u003eTechnical Specifications:  \u003c\/strong\u003e\u003cstrong\u003e \u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eNominal diameter: 100mm (4”) \u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminium\/polyester laminate with high-tensile steel helical wire reinforcement and PVC copolymer outer \u003c\/li\u003e\n\u003cli\u003eTemperature range in service: -30°C - 120°C (-22°F - 248°F) \u003c\/li\u003e\n\u003cli\u003eMaximum air velocity: 30 m\/s (98.4 ft\/s) \u003c\/li\u003e\n\u003cli\u003eMaximum positive air pressure: 2500 Pa (0.36 psi) \u003c\/li\u003e\n\u003cli\u003eSupplied length: 5m (16’ 5”) compressed to 0.5m (19.7”) \u003c\/li\u003e\n\u003c\/ul\u003e \u003cbr\u003e\u003cstrong\u003eFAQs: \u003c\/strong\u003e\u003cstrong\u003e \u003cbr\u003eQ: How should I install my ducting for best ventilation system performance?\u003c\/strong\u003e\u003cstrong\u003e \u003c\/strong\u003e\u003cbr\u003eA: All systems differ, but there are some basic guidelines which you should follow when designing your system: \u003cul\u003e\n\u003cli\u003eAvoid excessive lengths of duct.
