The SOLO A10S Smoke can is HFC-Free and is used for the functional testing of smoke detectors. It is approved by leading detector manufacturers and offers the reliability and quality expected by the industry. Chemicals used in detector test equipment need to be compatible with the plastics from which the detectors are manufactured. Not all test aerosols offer this compatibility which can lead to problems such as stress cracking in detectors, residue build up, damage to components and harm to the environment. The SOLO A10S works with the 330 dispenser to offer full functional testing of smoke detectors.
