AutoLine Pro SM701B High-Volume Automotive Smoke Machine — Red, Built-In Air Compressor & Ceramic Heater

AutoLine Pro SM701B is a high-volume automotive smoke machine with a premium ceramic heating cartridge and built-in air compressor for fast, reliable leak detection in EVAP, intake and vacuum systems.

The SM701B (2025 New Model) from AutoLine Pro is a purpose-built smoke diagnostic tool engineered to locate leaks across vehicle EVAP systems, intake manifolds, vacuum lines and other sealed circuits. Its ceramic heating element produces dense, consistent smoke while the integrated compressor supplies steady pressure, so you can spot small leaks without juggling separate equipment. Compact and durable, the SM701B is meant for technicians, home mechanics and fleet shops that need a dependable way to visualize leaks and speed troubleshooting.

How does the SM701B generate smoke and stay consistent?

The SM701B uses a premium ceramic cartridge as the heating core that vaporizes the specially formulated smoke fluid. Ceramic construction resists thermal fatigue and delivers even temperatures, which produces a steady, high-volume output rather than intermittent puffs. This consistency helps you identify small pinhole leaks and weak seals with greater confidence.

• Premium ceramic cartridge for long-lasting, even heat
• High-volume smoke output to reveal tiny leaks
• Designed for continuous operation during diagnostic checks

What systems and repairs can this smoke machine help with?

This unit is suitable for a wide range of sealed systems on modern vehicles, including EVAP canisters, intake boots, PCV systems, vacuum lines, and exhaust leak checks using appropriate adapters. It helps isolate the location of leaks so you can decide whether a clamp, seal replacement or component swap is required. The SM701B is versatile enough for both quick checks and more thorough diagnostic work.

• EVAP system integrity testing and canister leak location
• Intake manifold and vacuum line leak detection
• Accessory and gasket verification after repairs

How does the built-in air compressor improve workflow?

Having an integrated compressor eliminates the need for a separate air source and simplifies setup, making the tool more portable and faster to deploy on the shop floor or roadside. The compressor provides stable pressure to push smoke through the system under test, which helps the smoke escape at the precise fault point rather than dissipating prematurely. This built-in convenience reduces clutter and saves time during multi-step diagnostics.

• Self-contained unit with no external air supply required
• Consistent pressure output for clearer leak indication
• Compact footprint suited for benches or mobile use

What safety and maintenance should I expect?

The SM701B is built with durable materials to minimize maintenance; the ceramic cartridge is designed for longevity but is replaceable when end-of-life occurs. Use only recommended smoke fluid and follow ventilation guidelines to avoid inhaling fumes. Routine checks of hoses, fittings and seals keep the unit performing reliably and help prevent cross-contamination between jobs.

• Replaceable ceramic heating cartridge extends service life
• Use manufacturer-recommended smoke fluid for best results
• Inspect hoses and adapters regularly for leaks or wear

Who is this for: The AutoLine Pro SM701B is aimed at automotive technicians, independent mechanics, fleet maintenance teams and experienced DIYers who need an accurate, portable smoke diagnostic tool. If you diagnose EVAP faults, troubleshoot intake or vacuum leaks, or want a single unit with its own compressor to speed inspections, the SM701B delivers professional-level smoke output and robust construction for repeated shop use.
