Featuring a 34 mm Z-profile blade design, it is suitable for external wall applications where ventilation performance and protection against rainwater ingress are important considerations.\u003c\/p\u003e\n\u003cp\u003eThe BRL34Z-SM EWR provides a visual free area of 29% and a physical free area of 21%. The visual free area represents the apparent open proportion of the louvre when viewed from the front, while the physical free area indicates the effective open area available for air to pass through. These values help with product comparison and ventilation planning. Actual airflow will also depend on pressure drop, installation dimensions and the design of the wider ventilation system.\u003c\/p\u003e\n\u003cp\u003eManufactured from extruded aluminium profiles using EN AW-6060 T66 aluminium alloy, the louvre incorporates AISI 304 stainless steel mesh with 2.3 × 2.3 mm apertures. Its EWR (Extreme Water Resistant) design is intended for external ventilation openings where improved resistance to water ingress is required.\u003c\/p\u003e\n\u003cp\u003eDesigned for direct surface mounting onto a compatible wall or façade, the BRL34Z-SM EWR provides a practical finish for air intake and exhaust openings in commercial, industrial and building-services applications\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e \u003cbr\u003e\u003cstrong\u003eDIMENSIONS\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eMin. dimension (height x width): 200 x 200 mm\u003cbr\u003e\u003cbr\u003eMax. dimension (height x width): 2000 x 4000 mm\u003cbr\u003e\u003cbr\u003eOther dimensions on request\u003c\/p\u003e","brand":"vendor-unknown","offers":[{"title":"Default Title","offer_id":54929657495937,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0913\/8831\/3985\/files\/MR34Z-SM-EXTREME-WATER-RESISTANT.png?v=1761827457","url":"https:\/\/brookvent.co.uk\/products\/brl34z-sm-ewr","provider":"Brookvent","version":"1.0","type":"link"}
