Wodli 12V Smoke Machine Leak Detector — Dual‑Mode EVAP Tester with Built‑in Air Pump & Pressure Gauge

The Wodli smoke machine is a portable 12V automotive leak detector that combines a built-in air pump, adjustable flow meter and pressure gauge to find EVAP, intake, vacuum and other vehicle leaks quickly and safely.

This compact tester pairs independent smoke and air modes so you can pressurize systems and then pinpoint escaping smoke without carrying a separate compressor. Designed for 12V vehicles — cars, trucks, ATVs, motorcycles and small marine craft — it delivers up to 19 psi and shows live pressure and flow readings while protecting itself from overheating.

How does the dual-mode setup speed up leak finding?

Using air mode first pressurizes the circuit to reveal gross breaches, then switching to smoke mode makes small leaks visible as smoke escapes. Because the pump and smoke generator operate independently you use less consumable smoke fluid and complete tests faster.

• Air mode injects dry pressure to locate major leaks quickly.
• Smoke mode highlights fine leaks that air alone might miss.
• Independent controls let you alternate modes without extra tools.
• Built-in pump removes need for an external compressor, improving portability.

What controls and readouts help prevent damage during testing?

The tester includes an adjustable flow meter and a pressure gauge so you can set safe pressures and monitor them in real time. This prevents over-pressurizing sensitive hoses or components and helps you tune smoke output for clear visibility.

• Pressure gauge displays applied psi so you avoid exceeding safe limits.
• Flow knob adjusts smoke volume to match the job and reduce waste.
• Visible indicators show when the unit is overheating and pausing operation.
• Clear connections and fittings simplify sealing the test circuit reliably.

What types of systems and vehicles can this detector test?

Wodli’s leak detector is built for a wide range of low-voltage vehicles and systems — from EVAP and intake to crankcase and low-pressure turbo plumbing. It works with any 12V DC vehicle and many recreational or light commercial machines.

• EVAP systems, fuel tank vents and purge lines.
• Intake manifolds, vacuum lines and EGR ports.
• Crankcase ventilation, cooling and exhaust pathways at low pressure.
• Motorcycles, ATVs, snowmobiles, light trucks, speedboats and more.

How does the unit protect itself and the vehicle during long jobs?

A built-in thermal protection circuit monitors working temperature and pauses operation if the unit overheats, resuming only when temperatures have normalized. This safeguards internal components and prevents prolonged exposure of vehicle systems to unintended pressure or smoke.

• Automatic shutdown on excessive runtime or high internal temperature.
• Indicator lights inform when cooling is needed and when testing can continue.
• Durable internal pump reduces the chance of sudden failures compared with improvised setups.
• Designed for repeated field use without an external air source.

Who is this for? The Wodli smoke machine is aimed at technicians, DIY mechanics and mobile service operators who need a compact, all-in-one leak detection tool. It’s useful for anyone who regularly diagnoses EVAP, vacuum, intake or other low-pressure systems on 12V vehicles and wants accurate, visible results without hauling a separate compressor or complex rig.
