HRS, Inc. is an American manufacturer/assembler of industrial grade ceiling paddle fans and circulators. HRS is currently in the design phase of a new line of portable diamond plate explosion proof blowers for use in smoke extraction from buildings. Fogging and misting fans are also available. HRS paddle fans have been used in numerous fire stations to reduce heating costs, increase comfort and cool the stations in the Spring and Summer. HRS fans have extra heavy duty cast iron housings and will last far longer and move more air than hardware chain fans.
