EVAP Smoke Machine 12V – Built-in Pump, Cars & Trucks

EVAP Smoke Machine with Built-in Air Pump & Compressor – 12V DC

Quickly pinpoint leaks in your vehicle's EVAP system, intake, vacuum lines, and more with this professional-grade automotive smoke machine. Powered directly from your 12V battery, it features a built-in air pump compressor — no external air supply needed — and produces a large volume of visible smoke within 10 seconds for fast, accurate leak detection.

Why Choose This Automotive Smoke Tester?

• Cost-Effective Diagnostics: The built-in compressor generates 20–25 PSI of air pressure, pushing smoke through the system under test quickly and efficiently. Identify and fix leaks before they become expensive repairs.
• Everything Included: Right out of the box you get the smoke machine unit, built-in air pump, power cord clamp, smoke oil bottles (oil not included), multiple vehicle cone adapters, smoke delivery hose, intake bladder, spare bladder, and full-size automotive cap plugs. Baby oil or paraffin oil must be purchased separately.
• Wide Vehicle Compatibility: Suitable for cars, motorcycles, ATVs, light trucks, snowmobiles, off-road vehicles, and speedboats. Test EVAP systems, intake systems, cooling/EGR/exhaust systems, crankcase systems, engine airtightness, vacuum leaks, and low-pressure turbo leaks.
• Simple 4-Step Operation:
  1. Fill 10–15ml of baby oil or paraffin oil (not included) into the smoke machine.
  2. Disconnect the vehicle's intake pipe and connect it to the machine via the provided adapter.
  3. Connect to a 12V DC battery — the machine starts working immediately.
  4. Watch for smoke escaping at leak points and mark them for repair.
• Smart Overheat & Freeze Protection: Built-in thermal protection automatically shuts the unit down if it runs too hot, preventing damage. The indicator light turns off during protection mode and the machine resumes once it returns to a safe operating temperature. Do not add oil while the machine is running.
• Compact & Portable: Sleek, lightweight design stores easily in your vehicle's trunk so it's ready whenever you need it — at home, in the shop, or roadside.

Frequently Asked Questions

Q: Does the EVAP smoke machine come with smoke fluid or baby oil?

A: No, the machine does not include baby oil or mineral oil. The package includes an empty oil bottle. You will need to purchase baby oil, mineral oil, or paraffin oil separately. Add 10–15ml per fill before operating.

Q: Do I need a separate air compressor to use this automotive smoke machine?

A: No external air supply is required. This smoke machine has a built-in air pump compressor that generates 20–25 PSI of pressure on its own. Simply connect it to a 12V DC vehicle battery and it's ready to use.

Q: What systems can this smoke leak tester detect leaks in?

A: This machine is capable of testing EVAP systems, intake systems, cooling systems, EGR systems, exhaust systems, crankcase systems, engine airtightness, vacuum lines, and low-pressure turbo systems. It is compatible with cars, motorcycles, ATVs, light trucks, snowmobiles, off-road vehicles, and boats.

Q: What should I do if the smoke machine gets too hot during use?

A: The machine features built-in overheat protection. If it reaches an unsafe temperature, it will automatically stop producing smoke and the indicator light will turn off. Allow the unit to cool down to a safe temperature before resuming use. Never add oil to the machine while it is operating or still warm.
