Car park ventilation in Merseyside

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.

We carry out car park ventilation across Merseyside, including Liverpool, Birkenhead, St Helens, Southport and Wallasey. Prices use North West rates. The survey is free for new installations on the UK mainland, and the quote that follows is fixed and in writing.

What car park ventilation involves

Approved Document B sets out ventilation provisions for enclosed car parks, commonly 6 air changes an hour for normal use and 10 in fire conditions where mechanical ventilation is used. CO detection lets the system run at low speed most of the time and boost when pollution rises. Smoke control aspects are designed with the building's fire strategy and fire engineer.

Jet fan systems

Ceiling-mounted fans moving air towards extract points.

Ducted extract

Traditional ducted systems where layout suits.

CO and NO2 detection

Sensors and controls for demand-led running.
