The Redline Detection HD PowerSmoke is a heavy duty OEM-approved tool that quickly pinpoints high pressure leaks in HD trucks, buses, commercial, industrial, marine, and agricultural applications. The HD PowerSmoke locates invisible leaks that are the root cause of excessive aftertreatment maintenance, saving technician hours, increasing uptime, and demonstrating quick ROI. Variable pressure and flow simulate the boost load of a running engine so technicians can test with the engine safely off, allowing the technician to adjust flow as needed to find even minuscule faults before they turn into big problems. It is engineered to provide 2 to 20 psi and 40 times the volume of visible vapor of an automotive smoke machine to fill extra-large heavy duty systems.
