FOR IMMEDIATE RELEASE

ATI AIRTEST COMPLETES RESTRUCTURING

DELTA, BC, September 20, 2007 – ATI AirTest Technologies Inc. (“Airtest”) (TSXV: AAT) is pleased to
provide an update on the progress and development of the Company following its Annual General
Meeting and recently completed Non Brokered Private Placement.

The Company closed its private placement for securities on July 13, 2007, resulting in net proceeds to the
Company of slightly over $800,000.00 As a result of the financing, the Company was able to bring all of
its suppliers current and at the same time increase its inventory levels to accommodate the growing
demand for its products. During the past two months the Company has been busy re-establishing its
supply position with many of its larger customers based on improved delivery performance. Also during
this same period the Company has initiated some engineering projects to further enhance its current
product lines. This development process fits very well with today’s emphasis on energy management in
North America, and has already enhanced the outlook for increased growth in sales for the expanded
product line.

At the Annual General Meeting held June 27, 2007 the shareholders approved the conversion of debt to
shares which reduced the Company’s liabilities by $3,531,256. This enabled management to reduce
interest payments and redirect these funds to further add to inventory levels, which in turn will allow
increased growth.

Mr. George Graham, President of Airtest stated: “Prior to the completion of the financing, we were like
many growth oriented companies with fine product lines, who are unable to achieve their potential, due to
low inventory levels. The financing and the debt settlement has allowed us the opportunity to demonstrate
our ability to achieve our growth targets.”
