AutoLine Pro SM701 High-Volume Automotive Smoke Machine — Red, Built-In Compressor & EVAP Leak Detection

The AutoLine Pro SM701 is a compact, high-volume smoke machine with a built-in air compressor engineered to find EVAP, intake, and vacuum leaks quickly and reliably.

Built for independent shops, DIY mechanics, and mobile technicians, the SM701 combines a premium ceramic heating cartridge with an integrated compressor to produce steady, visible smoke that makes leak tracing faster and less guesswork. The unit ships with safe, OEM-approved smoke fluid and a pressure range tuned for automotive diagnostic work, delivering a simple three-step operation and continuous run capability with high-temperature protection.

How does the SM701 reveal hidden EVAP and vacuum leaks?

The machine forces dense, non-staining smoke into the system under controlled pressure so escaping smoke pinpoints leak locations. Smoke is generated by a durable ceramic cartridge that gives consistent output for clear visual tracing.

• High-smoke formula—designed for strong visibility in EVAP and intake paths
• Pressure output 15–21 PSI to pressurize common vehicle systems safely
• Integrated compressor eliminates separate air source setup
• Non-corrosive, sensor-safe fluid that won’t harm system components

How easy is it to set up and use the smoke detector tool?

Operation is straightforward: pour the included smoke fluid, connect power, and start the diagnostic cycle. The compact chassis and clear controls make it suitable for shop benches, service vans, or home garages.

• Three-step start: fill, connect, switch on
• Compact footprint for easy transport and storage
• Clear output indicators and protected heating element
• Includes full bottle of fluid—ready from first use

What performance and safety features help during extended testing?

SM701 is engineered for continuous operation with thermal safeguards and an efficient generation system to limit power draw and heat buildup. The premium ceramic cartridge and patented smoke path extend runtime while maintaining consistent smoke volume.

• High-temperature protection to prevent overheating during prolonged tests
• Patented generation reduces power consumption and temperature rise
• Up to five hours of smoke from provided fluid under normal conditions
• Designed to be safe around sensors and electrical components

What accessories and warranty support come with the SM701?

The kit arrives with OEM-approved smoke fluid and everything needed to begin diagnostics without buying additives or an external compressor. AutoLine Pro backs the unit with a three-year warranty and U.S.-based support for parts or replacement.

• Included high-smoke fluid—sufficient for initial multi-hour testing
• Integrated 5 L/min smoke output and motorized compressor
• Three-year manufacturer warranty with U.S. support
• Designed to be compatible with common diagnostic hoses and adapters

Who this is for: The AutoLine Pro SM701 is aimed at professional technicians, mobile mechanics, and serious DIYers who need a dependable, portable smoke source to diagnose EVAP, intake, and vacuum leaks without hauling extra compressors. If you value a tool that’s ready out of the box, built for repeated use, and supported by a generous warranty, the SM701 is tailored to your workflow.
