Abstract Air dehumidifier can be designed and modeled working on the simple principle of dehumidification of compressed air by means of collision with the number of cylinders arranged in series. This dehumidifier does not require any hygroscopic media or absorptive media such as activated alumina, silica gel, salt tablets, etc., which are used in other dehumidifiers. It does not require any refrigerant which is used in the refrigerated dehumidifier. The designed dehumidifier will be most reliable for the point of application. The dehumidifier will be designed to operate at a high pressure of 250 P.S.I. This can be designed as per the theory of thin cylinder. From the design calculations, the stresses of the proposed dimensions were within the safe stress limit. Using this dehumidifier will result into zero maintenance cost and zero operating cost as there are no moving parts in it. The other dehumidifiers available in the market are commonly known as ‘Air Filter’; they blast off when there is any fluctuation in the compressed air. To prevent this kind of accident, air dehumidifier is designed with the strengthen material.
