Petro Field Announces $1.5 million (US) Sales Contract

CALGARY, ALBERTA--(CCNMatthews - April 30, 2007) - Petro Field Industries Inc. (TSX VENTURE:PF) ("Petro Field" or the "Company") is pleased to announce a $1.5 million (USD) sales contract for 100 newly developed TEC 4CS series thermal oxidizers to be delivered by the third quarter. The contract signed April 20, 2007 is the Company's first with a major US producer in the Denver, Colorado area. As part of the pending company name change (previously announced April 19, 2007), this will also be the first major contract under the new Tornado Technologies Inc. banner.

Development of the TEC 4 was initiated in January, 2007 to address the stringent air quality venting regulations recently imposed by the EPA in the region. Rather than release raw, harmful production gases directly to atmosphere, the TEC 4 converts them to carbon dioxide and water vapor. The comparative result is a reduction in greenhouse gas effect by approximately 95%.

"The Colorado contract was earned for several reasons," said Les Weir, General Manager of Combustion Products for the Company, "most importantly that we developed and delivered a unique solution in under three months where others have been trying for over three years." The TEC 4 specifically delivers extremely high turn-down and destruction ratios, operates on low pressures, requires no on-site power, maintains a cool surface temperature (which benefits safety and allows it to be painted neutral colors), and has a significantly higher capacity than any competitive product.

The Company is already consulting with several other producers in the region about how the TEC 4 may be an effective solution for their similar situations. The Company's strategy is to focus on developing cost-effective, technologically superior combustion systems and move into new markets internationally.

Petro Field Industries Inc. is a Calgary, Alberta-based designer and fabricator of innovative industrial combustion systems, oil and gas processing equipment and Hydro Vac trucks.
