BEST WAY to solve a housing problem is to eliminate the need for housing! That's exactly what the Allis-Chalmers weatherprotected motor does. It eliminates the need for a costly building ... costly in added capital investment, costly in upkeep, and costly in extended construction time. Proved by Special Tesfs We know this weather-protected design can give you these savings ... plus dependable performance ... because we've tested it under extreme conditions. Take the 900-hp, 435-rpm, 4160-volt motor shown above. While running at normal speed and voltage, it was deluged with water at rates up to 40 inches per hour -- driven by winds up to 75 miles per hour. This was done repeatedly from all angles. But on inspection, no moisture was detected on the windings of this weather-protected motor. And other tests checked its effectiveness in keep- .mg' out wind-driven fine sand, Bulletin Describes Features The construction features that provide this eco nomical, super-splashproof performance are avail able in ratings for all major auxiliary drives.
