Exhaust Fume: Bus Operator Depot Case Study

The Client

A bus operator company, which has been in business for over 100 years approached Auto Extract Systems to help provide them with a new, off-plan bus depot to safely capture and removed exhaust fume. The operating company move around 175,000 people every day, so a new depot was essential to their operations to ensure they could continue to provide the best possible service for all of our customers, above and beyond what is legally required.

The Challenge

When a member of the Auto Extract Systems team visited the site to perform a free site visit (book yours today, click here), the building was a shell, with only the steel structure in place. However, with the use of architect’s drawings, an effective LEV (local exhaust ventilation) system was able to be specified for its intended use and all works completed prior to any vehicles entering the new, purpose-built bus depot.

During the latter stages of the build, Auto Extract Systems were invited in to complete in the LEV installation ahead of it being opened for operational use.

The Solution

The bus depot’s exhaust fume LEV system comprised of five all-metal, commercial-grade vehicle exhaust spring recoiled hose reels that each featured a 10-metre long, 125mm diameter high-temperature, crush-resistant exhaust extraction hose (capable of withstanding fumes up to 170°C) and a rubber nozzle that featured a clamp and an integral damper.

The reels were all connected via a common duct to a centrifugal fan to safely remove exhaust fumes to the atmosphere through a high-velocity cowl, as per the HSG 258: Controlling Airborne Contaminants at Work: A Guide to Local Exhaust Ventilation (LEV) guidance to provide a safer, pollution-free workplace.

The Feedback

The property manager responsible for the LEV installation commented: “I have worked with Auto Extract Systems Ltd for a number of years and whilst working on numerous projects, big and small in both the UK and Ireland; we have built up a strong working relationship and will continue to use them in the future for vehicle exhaust LEV (local exhaust ventilation) installations.”

Auto Extract Systems continue to maintain the specialist LEV systems installed with annual LEV testing services.
