Solary Automotive Smoke Machine EVAP Leak Tester — 30s Start, Adjustable Pressure, Built-In Pump

Solary Automotive Smoke Machine EVAP is a compact, built-in-pump smoke leak detector that produces visible smoke in ~30 seconds and lets you adjust test pressure for fast, accurate leak tracing.

Designed for technicians, DIY mechanics and fleet managers, the Solary smoke machine combines a pressure gauge, an adjustable pressure regulator and an integrated air pump to test EVAP, intake, exhaust and other sealed systems without an external compressor. It uses a small amount of baby oil to generate dense, non-corrosive smoke and includes thermal protection to reduce overheating risk. The unit is portable and suited for cars, motorcycles, ATVs, light trucks and marine applications.

How quickly does the unit produce smoke and how much oil is required?

The Solary unit generates visible smoke in about 30 seconds after startup and requires only 10–20 ml of baby oil for an initial test. That small volume creates a large amount of consistent smoke, so you can inspect systems without repeated refills.

• Start-to-smoke in ~30 seconds for fast diagnostics
• Initial fill: 10–20 ml baby oil, minimal ongoing consumption
• Dense, visible smoke suitable for pinpointing leaks

What pressure control and monitoring features does it offer?

This smoke machine has a dual-mode control layout: a pressure gauge for live readings and a pressure adjustment gauge for setting test pressure. Adjustable pressure allows careful testing of delicate systems and prevents over-pressurization during inspections.

• Built-in pressure gauge shows real-time internal pressure
• Pressure adjustment knob lets you fine-tune test pressure
• Safe testing range with visible readings for repeatable diagnostics

Can the device run without an external air source and how safe is it?

The Solary smoke machine includes an onboard air pump, eliminating the need for an external compressor or shop air. It also has temperature protection features to help avoid damage from extreme operating temperatures.

• Integrated air pump — fully self-contained operation
• Overheat protection at roughly +75°C and cold-protection to -20°C
• Lightweight and portable for field or garage use

Which systems and vehicles can it test effectively?

Use this smoke tester across many sealed systems: EVAP, fuel tank and cap seals, intake manifold gaskets, exhaust leaks, hoses and fittings. It’s compatible with a wide range of vehicles and small engines where leak detection is needed.

• EVAP system and fuel tank leak detection
• Intake, exhaust and hose/pipe fittings inspection
• Suitable for cars, motorcycles, ATVs, snowmobiles, light trucks and boats

Who is this for: The Solary Automotive Smoke Machine EVAP is built for professional mechanics, mobile technicians and knowledgeable DIYers who need a portable, reliable leak-finding tool. It’s particularly useful for shops that require quick diagnostics without setting up external compressors, and for owners of small fleets or recreational vehicles who want to rapidly identify seals and hose failures. If you need a compact, adjustable-pressure smoke source with onboard pumping and basic thermal protections, this unit delivers straightforward, repeatable results.
