Smoke generator Ancel S100 leak detection tool for automotive systems, handheld diagnostic device

Ancel S100 leak detection smoke generator is a compact handheld diagnostic device for locating leaks in automotive systems. The S100 produces visible smoke to help quickly identify leak sources in intake and vacuum lines, EVAP systems, exhaust, cooling circuits and other housings. Designed for workshop and DIY use, it combines portability with controlled smoke generation for efficient diagnostics.

Advantages

The S100 generates low-pressure smoke (0.5 PSI) for safe inspection of vehicle components and includes a standard 1/2 PSI regulator for stable output. It heats up in about one minute and operates from a 12V power source, enabling fast, convenient use. Built-in protections against overheating, reverse polarity and sparks increase durability and safe operation. The device is compact and portable, making it suitable for both simple and complex leak searches.

How to use

Fill the smoke generator with the recommended mineral oil, connect the power cable to a 12V source and attach the hose or appropriate adapter to the test point. Switch on the unit and wait approximately one minute for the heater to reach operating temperature, then allow smoke to flow at low pressure to reveal leaks visually. Use the smoke evacuation hose where needed and observe seals, joints and connections for escaping smoke.

Recommendations

Operate the Ancel S100 at the specified low output pressure (0.5 PSI) to avoid damaging sensitive components. Ensure correct polarity when connecting the 12V supply, allow the unit to cool before refilling oil, and follow local disposal rules for any used fluids.
