The Ancel L300 is a dual-function leak detector that combines an air pressure test and a smoke test into one compact device.
It supports leak testing:

• in the intake system,

• in the fuel system,

• In the EVAP vapor system,

• In the EGR system,

• in the exhaust,

• in the cooling system,

• crankcase ventilation,

• in turbocharger lines,

• in the salon.

With a digital pressure gauge, built-in air pump and temperature protection, the L300 allows for quick and reliable diagnostics for a wide range of applications.

🔧 2 operating modes

The device is equipped with separate switches to activate:

• Air Mode - Pressure Test

• Smoke Mode - smoke test

This allows you to immediately select the required diagnostic method, without any conversion or additional adjustment .
Separate pump and smoke generator control ensures accurate testing.

💨 Powerful smoke generator

The built-in system produces a smoke flow of 6–8 L/min , which quickly fills the system under test and allows you to clearly see the leak point.
Only 20 ml of test oil is required to perform the test.
The smoke is dense and stable—ideal for even micro leaks.

📊 Digital pressure indicator

The front panel has a digital pressure gauge that allows you to switch measurement units:

• PSI

• Bar

• kPa

• kg/cm²

An accurate reading allows you to track the pressure drop during testing - this clearly indicates the presence and intensity of a leak.

⚙️ Adjustable smoke flow

The device has a built-in flow meter with a fine adjustment knob.
Constant flow → indicates a leak
Flow reduction → indicates the size of the leak

This allows for an accurate assessment of the extent and location of the damage.

❄️ Overheating and freezing protection

Built-in protection ensures safe operation of the device under any conditions:

• Overheat Protection - turns off the device when it reaches 75°C

• Anti-Frost Protection — allows operation down to −20°C

Thanks to the built-in air pump , no external compressor is required.

🛢 Easy fluid control

The oil level indicator on the side allows you to quickly check whether there is enough test fluid in the device, protecting it from damage.
