We use the latest in pneumatic technologies from around the world to clean a/c systems to original. Self propelling cleaning nozzles access all duct surfaces by propelling 130 CFM 100psi volumes of air to cut the deris from internal walls whilst insuring no damage to internally lined duct.  The debris is collected by an 1100 litre per second vacuum.  All of our vacuums are fitted with Hepa 99.97% filtration to ensure optimum efficiency and eliminate any O.H.S. risk to yourself, your staff or your customers.
