When a plate with air discharing through its center is brought near a flat disc, the resultant partial vacuum between the two surfaces permits the disc to be lifted by the plate without contact.　This paper deals with the way in which the maximum weight which can be lifted is influenced by changing the ratio of the diameter of the upper plate with its orifice to the diameter of the orifice and the total pressure measured at the center of the lower disc.　Experimental results show that the maximum weight which can be lifted is linearly dependent on the total pressure. The results further show when the diameter of the upper plate is constant and the diameter of the orifice is made larger, the total pressure which is needed to lift a certain weight decreases, but the rate of the air flow increases.　It is also concluded that the diameter of the orifice excerts a greater influence on the pressure distribution than that of the upper plate, therfore the way in which the orifice is made is very important in designing the Pneumatic Lift.
