The 3000, and 4000, screw in EasyVent is made from Acrylonitrile Styrene Acrylate (ASA) which is a much more tough and durable plastic than PVC. ASA has an outstanding resistance to weathering, ageing and yellowing, meaning it will keep its high glossy finish for a long period of time. These vents are used to provide background ventilation in habited spaces which are meant to be naturally ventilated by removing polluted indoor air and replacing it with clean fresh outside air to create a healthy living environment, without creating a draught. These environmentally friendly vents consume no electrical power once installed and can operate 24 hours a day even if the windows are locked, which will prevent intrusion into the property. The 3000, and 4000, vents have a honeycomb grill which is designed to filter out unwanted airborne debris. Available in 3 colours: White, Brown, and Light Oak.When the vent is open the acoustic value is 37dB (for the 3000, and 33dB (for the 4000), which is considerably better than an open window. Features:
24 hour ventilation
Fixing screws and quick fit cover caps provided

Acoustic value of 37 dB (for the 3000), and 33dB (for the 4000) when open
