AUTOOL SDT206 Smoke Machine For Vacuum Leaks

AUTOOL SDT206Product OverviewThe AUTOOL SDT206 smoke machine for vacuum leaks is a mid-to-high-end automotive smoke leak detector in the SDT series. It uses dual built-in air pumps, independent air and smoke modes, a pressure gauge, a flow meter, and a flow control valve to help technicians find low-pressure leaks in EVAP, intake, exhaust, crankcase, fuel tank, turbo, pipe fitting, and vehicle sealing systems.Dual Built-In Air Pumps Air / Smoke Modes EVAP / Vacuum Leaks 12V Battery Power<18psiOutput Pressure<6L/minOutput Flow70WRated Power3 YearsWarranty Support Click to enlarge Click to enlargeBefore You Order And UseBefore You Order And UseReview the 12V power requirement, testing oil rule, oil refill limit, operating time limit, overheat protection, and hot-surface warning before using the SDT206 automotive smoke leak detector.12V Battery RequiredThe SDT206 smoke test machine must be connected to a DC 12V battery to operate. Do not connect it to an unsupported power source.Testing Oil Not IncludedDue to logistics restrictions, testing oil is not included in the package. Buy liquid paraffin or baby oil locally for use as the testing fluid.Add 10-15ml OnlyFill 10-15ml testing oil before use. Do not overfill, because too much oil leaves no space for smoke generation and may affect output.Refill When Smoke Gets ThinOnly refill when the smoke becomes thin. Do not add more than 15ml at a time, and always drain remaining test oil before adding fresh oil.8-Minute Use LimitDo not operate the smoke leak detector continuously for more than 8 minutes. Allow it to rest between uses to protect the machine.75°C ProtectionThe intelligent protection system automatically shuts off power if internal temperature exceeds 75°C. Wait for the unit to cool before restarting.Safety ReminderThe metal round section of the smoke tester can become hot during operation. Avoid direct contact to prevent burns.Do not refill testing oil while the smoke tester is running.If the machine stops due to temperature protection, allow it to cool down before restarting.The SDT206 is intended for low-pressure automotive leak checks. It is not a direct high-pressure A/C system pressure tester.Key FeaturesKey FeaturesSDT206 combines dual built-in air pumps, fast smoke generation, air and smoke testing modes, pressure observation, flow control, oil level visibility, oil drainage, and temperature protection in a compact diagnostic tool.Dual Built-In Air PumpsThe SDT206 has two built-in air pumps, so it does not require an external air source for normal smoke leak detection setup.Air Mode And Smoke ModeIndependent switches let you use air mode and smoke mode separately. This helps with pressure observation before smoke leak localization.Fast Smoke OutputThe smoke generator starts producing smoke quickly, and the tested pipe can be filled with smoke in about 30 seconds depending on system volume.External Pressure GaugeUse the pressure gauge to observe pipeline pressure. If pressure keeps dropping, the pipeline may have a leak that requires further inspection.Flow Meter And Flow ControlThe air flowmeter and flow control valve help you observe and adjust air flow volume, making testing safer for different automotive pipes.Oil Level And Oil OutletThe oil level gauge helps you observe the current oil volume, while the oil outlet allows recovery of surplus test oil when needed.Overheat And Anti-Frost ProtectionThe device turns off when temperature exceeds 75°C and can work normally at low temperature down to -20°C under proper conditions.Compact And Portable DesignThe compact body, handle, hook, cone adapter, and airbag adapter make the SDT206 easier to carry, hang, connect, and store.3-Year Warranty SupportAUTOOL provides up to 3 years of support for eligible non-human damage cases, including parts and troubleshooting assistance.

What Testing Oil Should I Use For SDT206? Testing oil is not included due to logistics restrictions. If professional smoke test oil is not available, buy liquid paraffin or baby oil locally and use it as the testing oil. How Much Testing Oil Should I Add? Add 10-15ml testing oil before use. Do not add more than 15ml at a time. Refill only when the smoke becomes thin, and drain remaining test oil before adding fresh test oil. If too much oil is added accidentally, drain some oil out before operation. Can SDT206 Detect EVAP System Leaks? Yes. AUTOOL smoke leak detectors can test leaks in the EVAP system. Use the proper EVAP testing tools and adapters according to the package contents and the vehicle test port. Can SDT206 Directly Test Automotive A/C System Leaks? No. The automotive A/C system operates at about 1.7-3.0MPa output pressure, while AUTOOL smoke leak detectors generate much lower pressure. SDT206 cannot directly pressure-test the automotive A/C system for leaks. It can only be used for segment-assisted air-conditioning pipeline checks under proper conditions. How Can I Use Smoke For Segmental A/C Pipeline Auxiliary Testing? First pressurize the air-conditioning pipeline using the proper method, then spray smoke and observe whether airflow blows the smoke. If smoke is disturbed by airflow, the location may indicate a leak point for further repair. This is only auxiliary segment testing, not direct high-pressure A/C testing. What Systems Can SDT206 Test? SDT206 supports low-pressure leak checks for EVAP, intake, exhaust, crankcase, fuel tank, car sealing, turbo leak areas, and various pipe fittings. Use the correct adapters and seal the tested section properly before inspection. What Power Supply Does SDT206 Need? SDT206 uses DC 12V car battery power. This makes it convenient for vehicle maintenance and easy to power in typical automotive repair environments. Can The Pressure Of SDT206 Be Adjusted? Most AUTOOL smoke leak detectors use fixed safe pressure settings. SDT MASTER allows pressure adjustment. SDT206 is not a variable-pressure model, but it includes an air flowmeter and flow control valve to help observe and adjust air flow during testing. What Accessories Are Included With SDT206? Refer to the Packing List image for the final package contents. The SDT206 package image shows the main unit, retail box, 12V power cable, smoke hose, cone adapter, hard rubber kits, airbag adapter, empty oil bottle, hanging hook, EVAP-related accessories, red caps, user manual, and other accessories shown in the image. Testing oil is not included. What Is The Difference Among AUTOOL Smoke Leak Detector Models? The AUTOOL smoke leak detector series includes EVAP-focused entry models, beginner built-in pump models, standard models, and higher-end models. SDT206 is a mid-to-high-end model with dual built-in air pumps, air and smoke modes, pressure gauge, flow meter, flow adjustment knob, oil drain valve, fault indicator light, and oil level gauge. SDT208 supports a wider pressure range up to 35psi. Compare air source, pressure, flow, mode, and accessories before ordering. How Long Is The Warranty For SDT206? AUTOOL provides up to 3 years of warranty support for eligible non-human damage cases.
