             QuestAir to supply hydrogen purification technology to

                             Synthetic Fuels Plant



VANCOUVER, B.C. - QuestAir Technologies Inc. (AIM: QAR; TSX: QAR) announced
today that one of its H-3200 hydrogen purifiers will be included in a synthetic
fuels plant located near Denver, Colorado.


The plant, or Product Development Unit ("PDU"), is currently being constructed
by Rentech, Inc., a leading developer of technologies and projects that
transform under-utilized energy resources into clean alternative transportation
fuels. The PDU will provide finished product to end users for testing purposes
as well as being a training facility for Rentech's patented and proprietary
process. The plant will produce approximately 10 barrels per day of ultra-clean
transportation fuels from coal.


Jonathan Wilkinson, President and CEO of QuestAir said that QuestAir's H-3200
pressure swing adsorption ("PSA") system will purify hydrogen for use in the
upgrading of liquid fuels in the coal-to-liquids plant.


"We are extremely pleased to be working with Rentech on this project, which we
believe is the first fully integrated coal-to-liquids facility in the US," said
Wilkinson. "This technology has the potential to convert large under-utilized
resources including coal, into clean burning transportation fuels to supplement
dwindling and ever more expensive supplies of conventional oil. We are excited
by the potential growth opportunity that the emerging synthetic fuels market
offers for our proprietary hydrogen purification technology."
