Improving Air Circulation and Temperature Control with Destratification Fans for Auto Service & Repair Shops
Auto service and repair shops combine high ceilings, large bay doors, vehicle traffic, heat-generating equipment, and demanding ventilation requirements within one workspace. Keeping technicians comfortable can be difficult when heated air collects overhead during winter, exterior air enters whenever service doors open, and equipment adds heat during warmer conditions. Airius destratification fans can help improve temperature distribution and general air circulation while working alongside the facility’s required exhaust and ventilation systems.
The Challenge
Automotive repair facilities require considerably more ventilation than typical commercial spaces because contaminants are generated by vehicles, fuels, chemicals, welding, cleaning products, and other service operations. ASHRAE identifies dedicated exhaust and outdoor-air ventilation as essential in automotive repair facilities, with additional exhaust required when vehicles operate indoors.
That necessary ventilation creates a secondary challenge. Large quantities of heated or cooled indoor air can be exhausted and replaced with outdoor air throughout the workday. High ceilings compound the problem during winter as heated air rises above technicians and collects near the roof. Large overhead doors repeatedly introduce outdoor air, creating temperature swings and requiring heating systems to recover conditions across the service bays.
During warmer periods, vehicle engines, compressors, diagnostic equipment, lighting, and other shop equipment can add substantial heat while stagnant areas make working conditions even less comfortable.
The Airius Solution
Airius fans can provide controlled supplemental circulation throughout service bays and general work areas, helping conditioned air reach technicians instead of remaining trapped near the ceiling. The fans are intended to complement rather than replace the dedicated exhaust and outdoor-air ventilation required for automotive repair operations..
For auto service and repair shops, two Airius systems are particularly well suited.
Air Pear EC Series
The Air Pear EC Series provides greater flexibility for shops with taller ceilings, different bay configurations, or areas requiring more targeted destratification. Its focused columnar airflow helps return accumulated ceiling heat toward occupied work areas during heating season. Multiple models accommodate ceiling heights from approximately 15 to 100 feet, making the series suitable for everything from conventional repair garages to large commercial vehicle service facilities. Variable-speed operation also allows airflow to be adjusted as doors open, work activity changes, or heating and cooling demands fluctuate
Onyx EC Series
The Onyx EC Series is the primary recommendation for automotive service bays and workshops. Designed specifically for powerful air circulation and cooling in garages and work shops, the Onyx EC can help improve air movement across large service areas and address heat buildup during warmer conditions. Standard models can provide coverage up to approximately 2,000 square feet in facilities with ceilings up to 50 feet. Variable-speed EC motors and BACnet or 0–10V integration allow circulation to be adjusted according to occupancy, seasonal conditions, and shop operating schedules
Potential Results
A properly engineered Airius installation could help reduce stagnant air zones, improve distribution between ventilation supply and exhaust points, provide more consistent circulation around structural obstructions, and help the existing mechanical ventilation system reach areas that otherwise receive limited airflow.
Improved air distribution could also complement demand-controlled ventilation systems by helping contaminants reach monitored and exhausted areas more effectively rather than remaining concentrated within poorly circulated portions of the garage.
It's time to repair your airflow
Every repair shop has different ceiling heights, service-bay layouts, vehicle types, door configurations, exhaust systems, equipment, and work processes. Airius fan placement and operating speeds can be designed around those conditions so supplemental circulation supports the facility’s HVAC and ventilation strategy without interfering with vehicle exhaust extraction, welding ventilation, paint booths, or other localized contaminant-control systems.
The objective isn’t simply to move more air. It’s to keep technicians comfortable while making better use of conditioned air throughout the service area.
