AIRVAC 911 Engine Exhaust Removal System

For a quarter century Air Vacuum Corporation’s dedicated team has been protecting first responders worldwide by automatically removing diesel carcinogens from fire stations and EMS facilities with its custom designed engine exhaust removal system, AIRVAC 911®.

AIRVAC 911® is the most effective and efficient exhaust removal system available. No building modifications, no hoses and no vehicle attachments. That means no interference with your daily operations or emergency response time. A sophisticated UL certified “Smart Timer” control panel automatically activates the AIRVAC 911® system so that particulate and gases are constantly removed 24 hours a day, 7 days a week, 365 days a year. It’s no wonder our system is preferred by stations worldwide.

Fact:  According to OSHA, prolonged, uncontrolled exposure to diesel exhaust and diesel particulate matter can increase the risk of lung cancer and cardiovascular, cardiopulmonary and respiratory disease*. Control the spread of hazardous contaminants in your station with AIRVAC 911®.

  • Only system  to remove  engine  exhaust that re-enters the building
  • Half the cost of hose systems

Benefits for EMS Facilities:
The same  benefits as fire departments, plus:

  • Maintains building temperature to protect sensitive medical equipment

Continuously filter the air and eliminate dead spots of exhaust. The AIRVAC 911® system is built on our proprietary “Coanda Design” which allows for 360-degree vertical and horizontal air movement throughout the entire bay area. In head-to-head comparisons with unidirectional air cleaners, AIRVAC 911® cleans more air at a faster and more efficient rate.  Eliminates “Engine Exhaust Backwash” and Hot Zones
AIRVAC 911® removes engine exhaust that re-enters the station when vehicles depart and return.
It also addresses the entire apparatus area and contaminant Hot Zones regardless of parking configuration,
vehicle quantity and the type of vehicle.
