QuestAir Technologies & ExxonMobil Research & Engineering Company Selected for R&D 100 Award

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 20, 2007) - QuestAir Technologies (TSX:QAR)(AIM:QAR) and ExxonMobil Research & Engineering Company ("EMRE") announced today that the QuestAir H-6200 Rapid Cycle Pressure Swing Adsorption ("RCPSA") system has been selected by the independent judging panel and editors of R&D Magazine as one of the 100 most technologically significant products introduced into the marketplace over the past year. For over 45 years, the prestigious R&D 100 awards have recognized the best in innovation on a global scale.

Jonathan Wilkinson, President & CEO of QuestAir Technologies, said: "The H-6200 RCPSA has been developed through the extraordinary efforts of many people at both QuestAir and EMRE. The selection for the R&D 100 award recognizes the truly innovative impact of applying rapid cycle technology. We anticipate this product will help refineries address the growing demand for hydrogen."

ExxonMobil's Emil Jacobs, Vice President of R&D, commented: "We are very pleased to receive this honor, which results from QuestAir's innovative concept combined with ExxonMobil's expertise in refinery and process engineering".

QuestAir has been working with EMRE since 2003 to develop the QuestAir H-6200 RCPSA for use in oil refineries and petrochemical plants. This product combines novel structured adsorbents and rotary valves, which together allow the QuestAir H-6200 to process gases at a much faster rate than conventional products. The resulting rapid cycle PSA is significantly smaller than a conventional PSA and is anticipated to offer advantages relative to other hydrogen recovery options including lower total erected costs, superior recovery performance, and improved operability.
