The motor body chassis rotates to provide connection in acute spaces. Cleaning the product is simple as all parts can be removed without removing the ducting.\u003c\/p\u003e\n\u003cp\u003eA non-mechanical backdraught shutter is included within the kit but extreme winds can result in the shutters opening and closing.\u003c\/p\u003e\n\u003cp\u003eConsideration must be given to protect the external termination or the position of this termination to prevent this occurrence as referenced within Part F 2021 - Control of ventilation intakes.

The pressure of the roof vent must not exceed more than 5pa for the NBR CoolBox 50\/Passive Duct and must not exceed more than 5pa for the NBR Coolbox 20\/30 to provide the below sound levels and assurances of flow rate at the valve.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.vent-axia.com\/range\/nbr-coolbox-50#downloads\" target=\"_blank\" title=\"Datasheet\" rel=\"noopener\"\u003e https:\/\/www.vent-axia.com\/range\/nbr-coolbox-50#downloads\u003c\/a\u003e\u003c\/p\u003e\n\u003cdiv id=\"overview\" class=\"prodsummary my-3 py-3 anchordiv\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"reedselectricalsupplies","offers":[{"title":"Default Title","offer_id":57668599808374,"sku":null,"price":635.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/7191\/2249\/files\/Coolbox50.webp?v=1776071732","url":"https:\/\/reedselectricalsupplies.co.uk\/products\/vent-axia-nbr-coolbox-50-412260","provider":"reedselectricalsupplies","version":"1.0","type":"link"}
