Good Day Tools (Cincinnati, OH) has introduced the Draft Simulator, a new hand-held, battery-operated instrument that will have major implications in furnace and boiler operations, says the company. The Draft Simulator can calibrate and test adjustable and factory-set pressure switches, and produces a sustainable vacuum pressure, allowing HVAC technicians to simulate the pressures draft inducers produce on furnaces while determining when pressure switches open and close, all without a furnace running or the pressure switch even attached to the furnace. The Draft Simulator also addresses safety issues, allowing users to catch a furnace problem before it becomes a tragedy. If the pressure falls or reaches a dangerous level, the switch shuts off the electrical current to prevent damage.
