Enclosed and underground car parks need mechanical ventilation to clear vehicle exhaust in normal use and, in many designs, to help clear smoke in a fire. We install and maintain jet fan and ducted extract systems with carbon monoxide detection and controls.
Our team is based in Great Barr, Birmingham, and we work throughout Gwynedd and Anglesey, from Holyhead and Bangor. The survey is free for new installations on the UK mainland, and the quote that follows is fixed and in writing.
