Respondol ATF C 3x3%
A 3% alcohol-resistant fluorine-free concentrate carrying ICAO Level B approval and GreenScreen Silver certification — the highest-credentialed AR-FF foam in the Respondol ATF family for ARFF and fuel-farm applications.
Respondol ATF C 3x3% is the ICAO-approved member of the Respondol ATF concentrate range, carrying ICAO Level B fire performance certification alongside its EN1568:2008 Parts 3 and 4, UL162 7th Edition, Lastfire, IMO, and GreenScreen Silver credentials. The 'C' designation in the product name denotes the Cold-Temperature variant formulation, which extends operational reliability at lower ambient temperatures compared with the standard Respondol ATF 3x3%.
ICOA Level B approval is the distinguishing procurement criterion for buyers sourcing foam for ARFF crash tenders and rapid intervention vehicles. Where the standard ATF 3x3% is fully specified for fuel farm fixed systems and industrial applications, the ATF C 3x3% is additionally qualified for vehicle-mounted ARFF use under ICAO Annex 14 provisions. For airport procurement teams running a single foam concentrate programme across both vehicle-mounted and fixed-system inventories, this product covers both application contexts from one SKU.
The product should be used with air-aspirating discharge devices for optimal foam quality. It is suitable for fresh, brackish, and seawater proportioning — important for GCC coastal airports such as those in Abu Dhabi, Dubai, Bahrain, and Qatar, where seawater-based emergency systems may supplement mains supply. Specific gravity is 1.01–1.05 at 20 °C; pH 7.5–8.5. Fully biodegradable, manufactured without fluorinated surfactants or fluorinated polymers. Minimum 10-year shelf life.
