The AIRVAC 911® Engine Exhaust Removal System provides 24/7 protection by controlling the spread of hazardous contaminants in your station so that everyone can breathe clean air. Protect 100% of the apparatus bay area by constantly monitoring and automatically removing diesel exhaust and particulate matter from your station. At the heart of our four-stage filtration system is the High-Efficiency “HEPA MAX 3000” (MERV 16) filter that has the ability to remove particles as small as 0.3 microns in size at an efficiency of greater than 95%. Our system also removes off-gassing and engine exhaust that re-enters the building. No hoses, vehicle attachments or tail pipe connections. No building modifications, ducting or external exhaust fans. No interference with daily operations or emergency response time. Plus, the flexibility to move vehicles from bay-to-bay. Energy efficient LEED/Green design. NFPA 1500 / OSHA / GSA Compliant. Made in USA. Request your free proposal at airvac911.com or 800-540-7264.
