A laboratory-based device for high performance diffusivity of fluid-air was developed. Acetone-air was used for the development at 30°C and a total pressure of 1.2atm. The volume of the containing cylinder for acetone was obtained 90cm³. Height and diameter of the cylinder was 20 and 2.4cm respectively. The level change of diffusion of the acetone after 10, 20, 30, 40, 50 and 60 minutes are 0.4, 0.57, 0.7, 0.8, 0.9 and 0.99cm respectively. The specific speed of the blower at the stated conditions is = 30.3rpm, area of the piston in the blower = 4.52cm² , discharge capacity of blower = 0.0023m³ min and the horse power of the blower is = 0.0774J/min. The values obtained from each of the design unit of the development shows that the device will produce reliable result when used for experiment.
