Compressed air is a vital medium for transferring energy in industrial processes. Compressors are efficient and reliable in meeting need and demand, especially in the industry while at the same time helping to reduce carbon footprint. However, there are several constraints using an air turbine as an operational element in generating electricity from compressed air. One of the key factors involved is the design of a blade that capable to increase the performance of the turbine and electricity generation from compressed air. Thus, this paper objectives are to develop a proposed design of a drag and lift type blade design and to evaluate the power generate that able to be harnessed from the force of the air. Additionally, the power coefficient that is harnessed from the generator using these new designs of blade also evaluated. In the experiment, the model is set up using the proposed concept of Savonius and Darrieus typed in order to generate electricity for small power equipment. Results show that these blade designs able to generate of 21-v for Savonius whereas 24-v for Darrieus from 0.3 MPa input source. Based on the result of an experiment, this study reveals that both type of blade design able to generate electricity constantly however, the performance of Darrieus vertical axis blade design is better compared to Savonius vertical axis blade design.
