Commercial ventilation, Kent
Car park ventilation in Kent
Jet fan and extract systems with CO detection for enclosed car parks, across Kent.
- From £27,450 + VAT per scheme
- Free survey

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 Kent 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 Ashford, Canterbury, Maidstone, Gillingham and Chatham.

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.
Maintenance
Planned testing of fans, sensors and controls.
Jet fan systems
