Carrier involved in road emissions capture project
1st September 2025
UK: Carrier’s airside team has collaborated with UK-based clean-tech innovation company Pollution Solution (UK) to develop an air handling system to capture roadside emissions.
The Roadvent system uses a network of re-engineered slot drains embedded in the road to extract toxic air from high-traffic environments. These emissions are then filtered through a multi-stage air handling unit developed with Carrier and released as clean air at street level.
Carrier’s engineering team assisted in designing and building a custom AHU that includes high-efficiency fans, HEPA filters, electrostatic precipitators and activated carbon filters.
The system is said to employ custom controls to adjust to real-time pollution levels using integrated sensors and software.
The Carrier-built AHU is connected to flush-mounted linear slot-drains in the road that extract emissions from traffic-heavy locations such as outside school playgrounds, bus stops, pedestrian crossings and congested city streets.
The first public installation of Roadvent is scheduled for later this year at a school site in Lewisham, London.
A full-scale prototype tested at the Millbrook Proving Ground demonstrated a 91% reduction in human exposure to roadside air pollution, measured at the height of a child.
