REGI U.S., INC.: Rand Cam Compressor Tests Successful

VANCOUVER, British Columbia--Aug. 2, 2004--REGI U.S., INC. (OTCBB:RGUS) (Berlin Stock Exchange:RGJ) and Reg Technologies, Inc. (TSX VENTURE:RRE), (OTCBB:REGRF) wish to announce that the Rand Cam(TM) compressor tests were completed under the direction of Brian Cherry, Vice President of Research and Development.

The tests have shown encouraging results of up to 25 P.S.I. with only 800 R.P.M. The testing for the compressor was completed on behalf of Trans Air Manufacturing for air-conditioning in bus applications. Mr. Cherry states, "The compressor tests have exceeded expectations."

The Rand Cam(TM) technology unique features include smaller size, vibration free, and low maintenance, which is the result of having only two moving parts (the vanes and the rotor). The light weight feature is due to the volumetric efficiency, which is 30%, versus 10% in the existing Wankel rotary engine, and 3-4% in the reciprocating piston engines that are used in automobiles today.

The Company is currently negotiating a license agreement for compressor applications, to be announced when the terms and conditions are finalized.

REGI U.S., Inc. owns the U.S. rights and the parent company Reg Technologies, Inc. owns the worldwide rights to the Rand Cam(TM) rotary technology. The Company has designed and built an air pump for fuel cell applications as well as an air pump for the lumbar seats in automobiles. Our licensee, Radian Milparts, is completing the production model 42 H.P. RadMax engine, to be used for military applications. For more information please visit www.regtech.com.
