The Vacutec Heavy-Duty Smoke Machine, No. WV711, features OEM-mandated STAR Technology, and is designed for testing turbocharged and other high pressure systems. This smoke machine delivers the densest smoke at any pressure, according to the company, using a contaminant-free UltraTraceUV smoke dye solution that finds high-pressure leaks that smoke alone may not find. The third generation variable-pressure machine's digital touchpad helps users avoid fumbling with regulators. Adjustable from 1 to 43.5 psi, it also quantifies leaks with pressure-decay and leak flow rate. The Heavy-Duty Smoke Machine includes a wireless remote.
