Vehicle Exhaust > Municipal & DPW Exhaust Systems
Municipal garages and DPW facilities run all day, every day. Snow plows, dump trucks, utility vehicles, heavy equipment, and vans cycle through service bays throughout every shift, each one generating diesel exhaust in an enclosed space. Unlike a commercial repair shop with predictable traffic, a municipal facility operates at the scale of a fleet operation, with multiple vehicles running simultaneously and maintenance staff working in those bays for hours at a time.
A properly designed DPW exhaust system captures those emissions at the source before they accumulate in the breathing zone of your mechanics and operators. Air Purifiers, Inc. designs and installs municipal garage exhaust systems matched to the scale, fleet mix, and budget realities of public works operations.
Off-the-shelf solutions aren’t designed for the demands of a public works facility. A DPW garage typically services a mixed fleet across multiple bays, which means no two service positions are exactly alike. A setup designed for a two-bay auto shop won’t cover a 10-bay facility maintaining heavy trucks, plows, and utility vehicles.
Beyond scale, older municipal facilities often weren’t built with modern ventilation standards in mind. Diesel exhaust particulates and carbon monoxide build up quickly in spaces without adequate source capture, and general dilution ventilation alone rarely meets OSHA exposure limits when multiple engines are running at once.
Air Purifiers, Inc. designs systems sized for your facility’s actual footprint and fleet, not a generic template.
Municipal garages vary in size, bay configuration, and the types of vehicles serviced. Air Purifiers, Inc. offers configurations to match that range.
Overhead hose reels are the most practical solution for most municipal garage bays. Compact when stored and easy to deploy, hose reel systems give your mechanics direct control over exhaust capture at each service position. Spring-operated and motorized options are available depending on ceiling height and usage volume.
For facilities with multiple bays or drive-through configurations, rail systems provide scalable exhaust capture across the full length of the service floor. Rail systems work well for DPW facilities that service larger vehicles or need to maintain capture across several bays simultaneously.
Portable exhaust extraction units provide a flexible option for facilities where fixed installations aren’t practical in every area, or where some service work occurs outside dedicated bays. Telescoping masts accommodate top-mounted, mid-mounted, and under-chassis exhaust configurations across a wide range of vehicle types.

OSHA sets permissible exposure limits for carbon monoxide and diesel particulate matter that apply to any indoor work environment, including municipal and DPW garages. General dilution ventilation is often insufficient to meet those limits when multiple diesel engines operate simultaneously in an enclosed space. Source capture is the most reliable way to control exposure at the point of generation. Air Purifiers, Inc. can assess your facility and help you understand where your current setup stands relative to applicable standards.
Mixed fleets present different exhaust configurations, vehicle heights, and bay positions that a single system type may not address on its own. Air Purifiers, Inc. evaluates your full fleet mix and facility layout before recommending a system, and can combine overhead hose reels, rail systems, and portable units to provide coverage across every service position.
Yes. Air Purifiers, Inc. can design a phased installation plan that prioritizes the highest-exposure bays first, adding coverage as budget allows. A phased approach is common in municipal facilities where capital expenditures require planning across fiscal years.
Air Purifiers, Inc. provides maintenance and service support after every installation. Routine service covers hose and nozzle inspection, connection hardware, and fan or mechanical components. Scheduling is coordinated around your facility’s operations to minimize disruption to your maintenance crew.
