The Vacutec® Smart Pressure® Diagnostic Smoke® Machine is designed exclusively for high-pressure turbo system leak detection and heavy-duty applications. Features award-winning, OEM-approved technology. Wireless remote included. The WV711’s Smart Pressure® technology produces the densest visible smoke vapor over the unit’s entire range of operating pressure. Smart Pressure® technology software electronics prevents thinning of smoke density that occurs when conventional units are set at high pressure. A denser smoke vapor means it’s easier to see at leak points. It also means a faster UltraTraceUV® dye deposit at the exact location of the leaks, which is essential for high pressure leak testing! You simply can’t find all the leaks without it!
