QuestAir to Supply PSA to Recover By-Product Hydrogen From Petrochemical Plant

FOR: QUESTAIR TECHNOLOGIES INC.

TSX, AIM SYMBOL: QAR

January 18, 2007

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Jan. 18, 2007) - QuestAir Technologies Inc.
(TSX:QAR)(AIM:QAR) announced today that it has received an order valued at approximately CDN $0.7
million for a QuestAir H-3100 pressure swing adsorption ("PSA") system to recover waste hydrogen from
a petrochemical plant in Odessa, Texas.

QuestAir's PSA will recover hydrogen from a by-product stream, producing purified hydrogen for re-use
in the petrochemical plant. In addition, excess product hydrogen from the recovery process will be
compressed for sale to third party 'merchant' customers.

The H-3100 will replace an existing 'conventional' PSA plant that has reached the end of its useful
life. A leading industrial gas company will integrate QuestAir's PSA with compression and storage
equipment at a facility adjacent to the petrochemical plant.

Jonathan Wilkinson, President and CEO of QuestAir said, "Demand for hydrogen is growing dramatically
in the oil refining and petrochemical industries, and the recovery of waste hydrogen is an important
source of hydrogen to meet this growing demand. QuestAir's PSA systems offer a cost-effective solution
for recovering hydrogen from a range of industrial waste streams, including chlor-alkalai offgas,
ethylene cracker offgas and various hydrogen-containing streams in the oil refining industry."

About QuestAir H-3100

QuestAir's H-3100 PSA product (formerly marketed under the HyQuestor(R) brand) purifies gas streams
containing hydrogen to high-purity hydrogen for use in a range of industrial and petrochemical
processes. QuestAir's PSA process and proprietary rotary valve technology deliver higher efficiency
than conventional PSA systems in a more compact, cost-effective package. Since 1997, QuestAir has sold
over 30 H-3100 plants to customers in Europe, Japan and North America.
