A jet nebulizer capable of producing a small particle mist for injection into any existing whole room/house/building air distribution system. The device pumps liquid scent from a bulk container through a supply line. The unit is turned on, a flow switch is closed, power is applied to a timer and a solenoid, opening the solenoid and starting the timer. Pressure in the supply line drops and closes the pressure switch which turns the pump on, forcing the liquid scent through a nebulizer nozzle into the air handling system. The pump runs according to the timer, and will continue to run until the timer shuts the solenoid valve. Once the timer shuts the solenoid off pressure builds in the supply line. The pressure opens the water pressure switch which turns the pump off. |
