The paper presents a method for determination of static characteristics of a gas lubricated face seal on the basis of experiment performed on the test bench. It has been developed a mathematical model QN=f(tg, pg, n) depicting effect of temperature of the gas tg, pressure of the gas pg and rotational speed of the shaft n on flow rate value of the gas QN. This dependency was used to determine pressure of the gas required for a selected operational parameters of the machine. To asses correctness of functioning of the seal it has been performed measurements of a selected 3D roughness parameters of the sealing rings. Slight changes in values of the 3D surface roughness of stationary and rotating rings before and after 25 working hours allow for conclusion about nearly contactless character of operation of the seal.
