The Autool SDT50 is a compact and efficient smoke machine, specially designed for quickly and reliably detecting leaks in various vehicle systems. What makes this model unique is the fully integrated air pump, so you do not need an external compressed air source. The diagnostic tool runs directly on a 12V DC vehicle battery, making it ideal for use in the workshop or on site.
This leak detection unit generates a constant stream of smoke with one press of a button. Thanks to a stable smoke output of less than 5 L/min and a controlled working pressure of approximately 0.7 bar (<10 psi), the SDT50 fills closed systems such as intake and exhaust paths. This makes even the smallest cracks or poorly sealing gaskets immediately visible through the escaping smoke, significantly reducing diagnosis time.
