Solary Automotive Smoke Leak Detector SD306 — Built-In Air Pump, 10s Smoke Output, Adjustable Flow

Solary SD306 is a compact automotive smoke leak detector with a built-in air pump that produces controlled smoke in 10-second bursts to locate EVAP, intake, exhaust and sealing leaks quickly.

Designed for technicians and vehicle owners who need a portable, all-in-one diagnostic tool, the Solary SD306 combines an internal air pump, adjustable flow meter and thermal protection to safely generate visible smoke for leak tracing. It fits cars, motorcycles, ATVs, light trucks and boats and removes the need for an external air source, making on-rack or roadside testing practical.

How does the built-in air pump simplify leak testing?

The integrated pump eliminates the need to connect an external compressor, shortening setup time and improving portability. Because pressure is supplied on-board, you can move from vehicle to vehicle without extra hoses or equipment.

• Internal pump supplies consistent air pressure for testing
• No external compressor required—ready out of the case
• Compact layout reduces setup and teardown time
• Portable for workshop, roadside or mobile service use

What makes the adjustable flow meter useful for different systems?

The SD306's flow meter lets you dial in the correct air pressure for fragile or robust piping, preventing damage while maintaining effective smoke production. This flexibility is important when switching between EVAP canisters, intake manifolds or exhaust fittings.

• Fine control of air pressure to match pipe tolerance
• Reduces risk of over-pressurizing sensitive components
• Helps produce a steady smoke volume for clearer leak visibility
• Quick adjustments between test types without additional parts

Are there safety features to protect the machine during use?

Yes—Solary built in thermal safeguards to protect internal components from extreme temperatures. The unit includes overheat protection around 75°C and safeguards against overcooling to maintain reliable operation in varied environments.

• Automatic overheat shutdown to prevent damage
• Low-temperature protection for cold-weather reliability
• Durable construction for repeated diagnostic cycles
• Lightweight design lowers handling strain during fieldwork

Which vehicle systems and situations is this smoke machine best for?

The SD306 is designed for common automotive sealing and vacuum systems: EVAP lines, fuel tank seals, intake manifold gaskets, exhaust joints and pipe fittings. It works equally well for small engines, motorcycles and marine applications, so it's a versatile choice for multi-vehicle shops or keen DIYers.

• EVAP leak detection and charcoal canister checks
• Intake and vacuum system diagnostics
• Exhaust and pipe fitting inspection
• Suitable for cars, motorcycles, ATVs, light trucks and boats

Who is this for? The Solary SD306 fits professional mechanics, mobile technicians and serious DIY vehicle owners who need a lightweight, transportable smoke tester that doesn’t rely on external compressors. If you want a single, rugged tool to speed up leak diagnosis across a range of vehicles and engine types, this unit provides adjustable control, built-in pressure, and protective features so you can find leaks faster and with more confidence.
