                 QuestAir to supply H-3200 hydrogen purifier to

                       AC Transit Hydrogen Energy Station


BURNABY, B.C. - QuestAir Technologies Inc. (AIM: QAR; TSX: QAR), a developer and
supplier of advanced gas purification systems for refinery, industrial and fuel
cell markets, announced today that it will supply a H-3200 hydrogen purifier for
use in the AC Transit Hydrogen Energy Station currently being built by
ChevronTexaco Hydrogen Company in Oakland, California. QuestAir's H-3200 will
purify hydrogen generated from natural gas using proprietary small-scale
hydrogen production technologies integrated by ChevronTexaco Technology Ventures
LLC.


Purified hydrogen from the station will fuel AC Transit's fleet of three 40-foot
fuel cell-powered buses, which are expected to enter passenger service in the
fall of 2005 and early 2006, as well as future fleets of light duty fuel cell
vehicles. The station will also have the capability of generating high-quality
electrical power using a stationary fuel cell and excess hydrogen produced by
the station.


Jonathan Wilkinson, President and CEO of QuestAir, said that the AC Transit
hydrogen station will be the seventh hydrogen fueling station in North America
and Japan to incorporate QuestAir's proprietary hydrogen purification
technology.


"QuestAir has developed strong expertise and experience in providing compact,
cost-effective hydrogen purification solutions to hydrogen fueling stations
around the world.  The AC Transit station demonstrates the incorporation of
QuestAir's H-3200 hydrogen purifier into ChevronTexaco Technology Ventures'
proprietary integrated technology. Together these technologies have the
potential to cost-effectively generate high-purity hydrogen fuel from natural
gas," Wilkinson said.


QuestAir's H-3200 purifies gas streams containing hydrogen to high-purity
hydrogen for use in industrial processes, hydrogen fueling stations and
stationary fuel cell power plants. The H-3200's optimized Pressure Swing
Adsorption (PSA) process and proprietary rotary valve technology deliver higher
efficiency than conventional PSA systems in a more compact, cost-effective
package. Since the product launch in 2003, QuestAir has sold 24 H-3200 systems
to customers in Europe, Japan and North America.
