How it works with your operations

How the System Works

The AIRVAC 911® units are self-contained and suspended from the ceiling which insures they do not interfere with daily activities. All units are wired into a watertight NEMA 4 box UL 508 certified "Smart Timer" control panel which automatically activates & shuts down upon every call. Once activated the system runs for a preset time, generally 15–20 minutes, removing harmful gases and particulates automatically without interfering with daily operations. The AIRVAC 911® System addresses the complete apparatus bay areas 24/7/365.

Installation of the AIRVAC 911® System

Installing the AIRVAC 911® Engine Exhaust Removal system is simple and can be performed by an AIRVAC 911® technician or a local electrician. Units are ceiling hung via chain or threaded rod. We do not require any structural changes to your station (e.g. holes in the wall/roof or additional ceiling supports). Units are evenly spaced throughout the entire apparatus area and mounted above the apparatus, thus eliminating any interference with vehicle movement. Power is then supplied to each unit's location (110/220 Volt) through our AVEC "Smart Timer" Control Panel. A multitude of low voltage switches are available for automatically activating the system without requiring any hands-on involvement. It's that easy.

Manufacturer Direct

The AIRVAC 911® Engine Exhaust Removal System is the industry's original hoseless system manufactured and distributed directly by Air Vacuum Corporation. This eliminates the "middle man", keeps the cost down, and you deal directly with the people who know the equipment inside and out.

Multi-directional Vertical & Horizontal Airflow Design

Industry's only Vertical & Horizontal Airflow System

The AIRVAC 911® Engine Exhaust Removal System is the only hoseless system that incorporates the industry's most effective airflow design—the Coanda Airflow Design Principle. In head-to-head comparisons with horizontal systems, the AIRVAC 911® System's Unique Multi-directional Air Flow cleans air in a more uniform and natural pattern, at a higher efficiency than horizontal systems.

UL Certified AVEC "Smart Timer"

Each system is sold with a pre-wired custom UL certified AVEC "Smart Timer" control panel that is timed to operate the system and its activation devices. A standard activation package consists of door switches and photo eyes (trigger the system upon vehicle movement). Once the system is triggered by any one of the installed field devices it will run for a complete cycle and shut itself down automatically. This sequence will be repeated when a vehicle returns from a call. There are a number of options for controls, including zoning-where units in different bays can operate off one control; sequential activation, where units activate in pairs, decreasing amp load; and a variety of additional switching devices.

Only System to Eliminate "Exhaust Backwash"

The AIRVAC 911® Engine Exhaust Removal System is the only system on the market to eliminate the problem of "exhaust backwash" — the fumes that re-enter the building as vehicles leave and return.
