QuestAir to Supply PSA for Japanese Hydrogen Recovery Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 19, 2008) - QuestAir Technologies Inc. (TSX:QAR)(AIM:QAR)
announced today that it has received an order valued at approximately CDN $1 million for an H-3100 hydrogen
pressure swing adsorption ("PSA") system. The order was placed by Iwatani International Corporation
("Iwatani"), Japan's leading supplier of merchant hydrogen, and the PSA will be used in a new hydrogen recovery
project at an undisclosed location in Japan.

Jonathan Wilkinson, President and CEO of QuestAir, said, "Hydrogen recovered from industrial sources has an
extremely low greenhouse gas footprint when compared to more conventional methods of hydrogen production.
Iwatani has shown great leadership in the development of low cost, low-carbon sources of hydrogen for both
industrial and fuel cell customers in Japan."
