          QuestAir and Hydro-Chem sign manufacturing license agreement


VANCOUVER, B.C. - QuestAir Technologies Inc. (AIM: QAR; TSX: QAR) announced
today that it has signed a licensing agreement with Hydro-Chem, a leading global
supplier of industrial hydrogen plants.


Under the terms of the non-exclusive agreement, Hydro-Chem will manufacture
QuestAir's H-3100 pressure swing adsorption ("PSA") systems under license, for
incorporation in Hydro-Chem's industrial hydrogen plants sold to customers
world-wide. QuestAir will receive a licensing fee for the supply of its
proprietary rotary valves and process design. The agreement is the first of its
kind signed by QuestAir allowing an established hydrogen plant fabricator to
build PSA's based on QuestAir's rotary valve design. The initial term of the
agreement is five years.


"We are extremely pleased that QuestAir's H-3100 hydrogen purifier will be
included as a standard offer in Hydro-Chem's product line," said Jonathan
Wilkinson, President and CEO of QuestAir, "Hydro-Chem is the leading supplier of
hydrogen plants in the capacity range up to 5,000 normal cubic meters per hour
("NCMH"), having supplied over 140 plants around the world . This agreement
significantly expands QuestAir's access to the global hydrogen plant market in
this capacity range."


"Going forward, our relationship with Hydro-Chem will help establish QuestAir's
PSA systems as an industry standard for hydrogen purification in industrial
hydrogen plants sold to merchant industrial gas companies and on-site hydrogen
end-users alike," Wilkinson said.


Dennis Norton, Hydro-Chem's president said "We are very impressed with the
compact design and operating capability of QuestAir's PSA technology. In
addition to offering a significant size reduction, QuestAir's H-3100 delivers
extremely competitive performance versus conventional PSA systems while offering
the lowest cost of ownership in terms of initial purchase, installation and
lifetime maintenance costs."
