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.
Across Somerset the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Taunton, Yeovil, Bridgwater, Portishead and Frome.

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.

Sensors and controls for demand-led running.
