ABSTRACT:
An air-assisted sprayer comprises a platform, a fluid cup, an air reservoir, a spray cap, a pressure line, a fluid reservoir and a poppet valve. The fluid cup is connected to the platform to hold a volume of fluid. The air reservoir extends through the platform and is configured to receive pressurized air. The spray cap is connected to the platform to receive pressurized air from the air reservoir. The pressure line connects the air reservoir with the fluid cup to pressurize the volume of fluid. The fluid reservoir extends from the fluid cup to the platform to provide pressurized fluid to the spray cap. The poppet valve is in fluid communication with the pressure line between the volume of fluid and the air reservoir to prevent fluid from entering the air reservoir.
