The Promise To a Healthier Indoor Atmosphere

The IAQ Solutions Story of Commitment to and Development of PCO

Photo Catalytic Oxidation (PCO) is a technology known to improve indoor air quality and has been in development for over forty years. Prior to 2005, many major universities and HVAC companies attempted to make the necessary corrections to this technology, commercialize and patent PCO technology but were unsuccessful. The interest, around the world, was in reducing volatile organic compounds (VOCs) and biological contaminants within one system, thus eliminating the need for layers of technology and expense. It was a complex endeavor with multiple obstacles to overcome in order for it to be effective and accepted in commercial application: considerations were regarding incomplete oxidation, life-cycle of catalyst, harmful by-products, and more.

Like many great modern innovations success starts with a vision, a goal, perseverance and a couple of guys in a garage! The hard work and determination of these gentlemen of Lubbock, TX, led to eliminating the obstacles and ultimately changed the face of indoor air quality today. One major accomplishment came in overcoming incomplete oxidation, which when incomplete creates the by-products of aldehydes; likely more harmful than what passed through the PCO panel. Purification needed to work at air speeds of 500 fpm or less to comply with commercial air handlers, and the dwell time at 500 FPM had to deliver a high level of kill rate and oxidation within the catalyst panel. Each of these obstacles was overcome and perfected. In addition, the quality of the catalyst had to be, and was, elevated to create a favorable life-cycle for the panel (now 15 years) and to keep silica from forming on the panel.

All of these elements were perfected and the system was trademarked as GAP™ by IAQ Solutions. Now ready for the market, the garage scientists initially introduced the system in casinos to remove the odor of smoke.

The United States Army conducted a long group of tests in their Bio 4 labs, at Dugway Proving Grounds (UT), with chemical and live bio agents. The Department of Defense had an intense interest in successful PCO for its potential in addressing anti-terrorism protection. Their tests proved the biological reduction (kill) rate and deactivation was very impressive. The GAP™ system was able to remove or neutralize better than 98% of airborne bacterial spores and could not detect any harmful contaminants in the exhaust stream (currently used at many military bases). Following this success, Trane (the international OEM HVAC manufacturer) and others performed their own testing to successfully verify performance.

Today, IAQ Solutions and the GAP™ purification system is marketed by Air Quality Distributors (AQD); AQD holds the master distribution license and seeks partnerships throughout North America to distribute the IAQ Solutions line.
