In 1977 the success of WSC was achieved under the direction of Jim Waller, the company’s founder and president. Initially a home-based filtration sales operation, company growth quickly warranted a sales facility. Jim’s entrepreneurial spirit took hold and the company opened its first distribution center in 1979 and quickly expanded its product offering to include a wide range of air handling equipment.

In 2010 WSC relocated to it’s current location in White House, Tennessee and the business continues to flourish. For more than four decades, the company has enjoyed an excellent reputation for product and service quality, dependability, and business integrity.
