For example, in restaurant kitchens, commercial range hoods and exhaust fans draw large amounts of air out of the room. This creates negative air pressure in the room, which can deprive an ordinary commercial gas water heater of sufficient make-up air required for safe, efficient, proper operation.  

In negative air pressure situations, downdrafts can occur inside an ordinary water heater, compressing the burner flame, resulting in impaired water heating performance and recovery efficiency.  Negative air pressure can also generate Carbon Monoxide buildup, and other potential safety hazards.

Sandblaster® Force™ is the solution, because it doesn't share the inside air!  It is equipped with a factory-installed blower and two-pipe system for intake of make-up air and separate exhaust venting.  This unique air delivery system (patent pending) insures that Sandblaster® Force™ is immune to negative air pressure.  Sandblaster® Force™ also helps reduce space heating or air conditioning costs, because it does not consume heated or cooled air from inside the building.
