The new HFC-Free smoke aerosol for the functional testing of smoke detectors. Like all Solo products, Solo A10 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. Solo aerosols are the most thoroughly researched solutions – approved by leading detector manufacturers, third parties and fire engineers. - UL & ULC Certified - Approved by world leading detector manufacturers - Non-flammable (same as Solo A4) - HFC-Free – fully compliant with latest regulations: Protecting the global environment - Silicone Free – prevents detector contamination: Protecting the local environment
