AutoLine Pro EVAP Smoke Machine SM701 — Red compact high-volume unit with built-in compressor

The AutoLine Pro SM701 is a compact, high-volume automotive smoke machine with a built-in air compressor designed to find EVAP, intake, and vacuum leaks quickly and reliably.

Whether you're a DIY enthusiast or a professional technician, the SM701 combines a premium ceramic heating cartridge, an integrated compressor, and a long-lasting high-smoke fluid to produce steady, visible smoke for pinpointing hard-to-find leaks. Its compact footprint, safety protections, and included fluid make it ready for garage or mobile use without relying on external compressors or additional supplies.

How does the SM701 reveal leaks in EVAP and vacuum systems?

The unit generates dense visible smoke that travels through sealed plumbing and escapes where rubber hoses, gaskets, or fittings fail. Because the smoke is continuous and high-volume, it highlights small pinholes and slow leaks that are often missed with pressure or listening tests.

• High-volume output: approximately 5 L/min for clear visibility
• Built-in compressor: 15–21 PSI suitable for most auto systems
• Ceramic heating cartridge: steady smoke without sputtering
• Included premium fluid: long run time for multiple diagnostics

What safety and efficiency features protect my vehicle and battery?

The SM701 uses temperature protection and a patented generation method to limit power draw and prevent overheating during extended runs. The low electrical load and supplied fluid capacity allow for prolonged testing without excessive battery drain or repeated refills.

• High-temperature protection to avoid overheating
• Patented smoke generation reduces power consumption
• Fluid supply rated for extended smoke sessions — fewer interruptions
• Compact design for secure, ventilated placement during tests

How do I set up and operate the smoke machine?

Operation is intentionally straightforward: add the provided smoke fluid, connect power, and start the unit. The SM701’s clear controls and integrated compressor remove the need to rig an external air source, making setup faster and safer in tight garage spaces.

• Three-step startup: pour fluid, connect power, start diagnostics
• Integrated compressor removes need for extra air equipment
• Lightweight, portable housing for mobile or bench use
• OEM-safe fluid that’s compatible with sensors and system components

What does the warranty and included kit cover?

AutoLine Pro backs the SM701 with a three-year warranty covering manufacturing and operational defects, and the kit ships with a ready-to-use supply of premium smoke fluid. That combination means fewer delays for replacements and immediate capability out of the box.

• Three-year manufacturer warranty with U.S.-based support
• Included high-smoke formula—no empty bottle surprises
• Replacement parts and support available for covered defects
• Designed for repeated garage and mobile service use

Who is this for: The AutoLine Pro SM701 fits independent mechanics, mobile technicians, and car owners who want a professional-grade smoke tester without a workshop-sized compressor. If you need reliable smoke output, built-in air pressure, and a durable heating element in a portable package—plus warranty-backed support—the SM701 provides an efficient leak-detection solution for light commercial and personal automotive diagnostics.
