QuestAir Supplies System to Recover Hydrogen From Ethylene Cracker Offgas in Brazil

BURNABY, BRITISH COLUMBIA--(CCNMatthews - Dec. 22, 2006) - QuestAir Technologies Inc.
(TSX:QAR)(AIM:QAR) announced today that it has received an order valued at approximately CDN $0.6
million for a QuestAir H-3100 hydrogen purifier to recover hydrogen from ethylene cracker offgas at a
petrochemical plant in Brazil.

QuestAir's H-3100 system will recover hydrogen from offgas produced by an ethylene cracker being
installed in a new linear low density polyethylene (LLDPE) plant located near Sao Paulo, Brazil. The
high-purity hydrogen product from QuestAir's H-3100 will be used in the production of polyethylene.

Jonathan Wilkinson, President and CEO of QuestAir said, "Ethylene cracker offgas is an important
source of cost-effective hydrogen to meet the burgeoning demands for hydrogen in the petrochemical
industry, and we are excited by the growth prospects for QuestAir's hydrogen recovery systems in this
application. The advanced H-6200 hydrogen purifier that we have developed in collaboration with
ExxonMobil Research and Engineering Company is targeted specifically at larger capacity applications
in this market."

"In addition, this is our first sale into Latin America, which represents a significant growth market
for QuestAir," Wilkinson said.
