FOXWELL SD101 PRO EVAP Smoke Leak Detector Automotive Built-in Air Pump Car

The Foxwell SD101 Pro is a professional-grade smoke leak detector designed to pinpoint leaks in automotive systems with precision and ease. Featuring a built-in air pump, dual air/smoke modes, and a flow meter, this tool offers efficient testing for fuel, intake, exhaust, EVAP, and more. Compatible with cars, motorcycles, trucks, and boats, it’s a must-have for mechanics and DIYers, delivering fast results with low energy use and a 10-minute work cycle.

Leaks in vehicle systems can cause serious issues:

• Vacuum Hose Rupture: Leads to a rich mixture, high idle, poor starts, surging acceleration, high fuel use, and black exhaust smoke.
• Blockages: Cause idle drift and stalling.
• Air Leaks: Weaken engine power.
• Fuel Tank Gaps: Result in fuel vapor leaks, waste, and unstable idling.
• Exhaust Leaks: Increase noise and emit harmful gases.
  The SD101 Pro quickly identifies these problems, saving time and repair costs.

• Precision Testing for Sensitive Systems:
  • Crankcase Test: Detects excessive pressure or corrosion causing oil leaks.
  • Intake System Test: Finds leaks reducing engine power.
  • Car Sealing Test: Checks airtightness for dust, noise, and water issues.
  • Fuel Tank System Test: Identifies gaps in tanks or piping.
  • Turbo Test: Spots coolant leaks causing high temps.
  • EVAP System Test: Pinpoints fuel vapor leaks affecting idling and emissions.
  • Exhaust System Test: Locates leaks increasing noise or pollution.
  • Pipe Fittings Test: Tests brake, steering, cooling, and turbo hoses.
• Built-In Air Pump: No external gas source needed—plug into a 12V battery and start testing instantly. Enhances portability and setup speed.
• Dual Modes:
  • Air Mode: Uses the flow meter to confirm leaks quickly.
  • Smoke Mode: Generates smoke to visually locate leak points, improving efficiency.
• Flow Meter: Monitors air/smoke flow with a float to detect and measure leaks down to the millimeter. Adjustable knob maintains optimal output for various systems, reducing fluid waste.
• Low Energy Design: Patented smoke generation consumes less power and e-liquid compared to peers, even at high smoke concentration.
• 10-Minute Work Cycle: Outperforms competitors’ 5-minute cycles, supporting extended tests on large systems like cabs and water tanks without downtime.

• Vehicles: Cars, motorcycles, snowmobiles, beach bikes, light trucks, heavy-duty trucks, and speedboats.
• Systems: Fuel pipes, air intake, cooling tanks, EVAP, exhaust, and various hoses (brake, steering, turbo, etc.).
• Power: DC 12V battery (red clamp to , black to -).
