The Easyvent 3000 white trickle vent is made from Acrylonitrile Styrene Acrylate (ASA), a much tougher and durable plastic than PVC. ASA has an outstanding resistance to weathering, ageing and yellowing, meaning it will keep its glossy finish for a long time. Easyvents are so called as the vents are indeed easy to fit. Please see the datasheets below for routing details and drawings. Use the routing shown to enable the maximum EA value. These vents are used to provide background ventilation in habited spaces by removing polluted indoor air and replacing it with clean fresh outside air to create a healthy living environment, without creating a draught. Background air circulation helps to reduce condensation and damp. The honeycomb grill is designed to filter out unwanted airborne debris. When the vent is open the acoustic value is 37db. Come complete with cover caps for the screws.
Please note: Both external and internal vents are white (RAL 9010)
