CFTNSXND 12V Smoke Machine Leak Detector with Built-In Pump, Gauge & Adjustable Flow Meter — Portable EVAP/Intake Tester

The CFTNSXND Smoke Machine is a compact 12V automotive leak detector that produces thick diagnostic smoke fast, with a built-in pump, pressure gauge and adjustable flow meter for testing EVAP, intake, turbo and other low-pressure systems.

This portable smoke tester arrives ready to use and is engineered for quick leak identification on cars, motorcycles, ATVs, light trucks and small boats. It includes the core accessories you need — hose, adapters, cap plugs and oil bottles — and features overheat protection and a built-in compressor so you don’t need an external air source. Follow safe-use guidelines and the oil recommendations to get reliable, repeatable smoke output.

How quickly does the unit produce smoke and what power does it need?

The machine warms up rapidly and can generate visible smoke within about 10 seconds after connecting to a 12V source and adding the recommended oil. It is designed exclusively for 12V DC systems; using higher voltages will damage internal components.

• Typical warm-up: ~10 seconds to visible smoke.
• Power requirement: 12V DC vehicle battery connection only.
• Automatic thermal shutoff protects the unit if it overheats.
• Use a 12V converter for 24V systems; do not connect 24V directly.

What kinds of leaks and vehicles can this smoke machine test?

It supports a broad range of low-pressure diagnostic jobs: EVAP systems, intake and vacuum leaks, cooling/EGR/exhaust fittings, crankcase and turbo boost lines, plus general pipe and fuel tank fittings. The kit suits cars, motorcycles, ATVs, snowmobiles, off-road vehicles, light trucks and speedboats.

• EVAP and fuel system leak detection.
• Intake, vacuum, crankcase and low-pressure turbo leaks.
• Applies to small engines and light marine craft.
• Multiple adapters and cap plugs included for diverse fittings.

What accessories and consumables are included, and what must I supply?

The package contains a built-in air pump, pressure gauge, adjustable flow meter, smoke hose, intake bladder, cap plugs, various cone adapters and empty oil bottles. You must supply the smoke oil — high-purity mineral oil or baby oil — because the kit ships with empty bottles only.

• Included: built-in pump, power cord clamps, flow meter, gauge, hoses and adapters.
• Included: empty oil bottles (oil not included) and a spare bladder.
• Not included: baby oil/mineral oil — purchase separately for operation.
• Recommended oil fill per run: 10–15 ml; maximum 20 ml to avoid overfill.

How do I operate the smoke tester safely and maintain optimal performance?

Operation is straightforward: add the recommended oil amount to the bottle, hook the unit to the vehicle intake or test port, and connect to a 12V battery. Monitor oil level, avoid adding oil while the unit runs, and let the device cool before refilling or addressing thermal shutdowns.

• Fill new oil only when the unit is cool; never add oil during operation.
• If smoke weakens, add fresh oil after cooling; replace oil after ~3 hours of use.
• Avoid overfilling (max 20 ml); overfill prevents proper startup or reduces smoke output.
• Work outdoors or in well-ventilated areas; a slight odor is normal.

Who is this for? The CFTNSXND Smoke Machine is built for DIY mechanics, mobile technicians and small shop owners who need a compact, all-in-one smoke tester for low-pressure leak diagnostics. It’s also useful for hobbyists working on motorcycles, ATVs, light marine craft and restorations where pinpointing vacuum, intake or EVAP leaks quickly saves time and parts. If you need a portable 12V smoke source with built-in pump, flow control and a complete accessory set — and you’re prepared to supply the recommended mineral or baby oil — this kit offers immediate diagnostic capability with user-friendly safeguards and a one-year warranty for quality issues.
