Ambi-Rad's vacuum fired units draw air evenly through the tube, rather than blowing air down the length. This results in less turbulence, providing a longer, thinner, more even flame and more uniform heat output along the entire tube length. The complete assortment of model lengths and intensities can be designed to fit any application.

The vacuum series is available in U-Tube and Straight Tube configurations and offered in three different models:

• SC - Utilizing an AlumiThermÔ combustion chamber and aluminum reflectors, the SC series provides the advantages of a true vacuum system and economical pricing.

• ER -The ER adds to the advantages of the SC by providing the efficiency and long life of stainless steel reflectors.

• GX - The ultimate in quality, efficiency, and durability. Featuring all stainless steel tubing and reflectors.
