This tool is designed for serious shops and technicians. It is the most advanced smoke machine available to date. This advanced design eliminates the need for nitrogen when testing an EVAP system. The Total-Tech(TM) operates on White Medicinal Mineral Oil H-1 (baby oil) and does not require annual oil changes. The Total-Tech(TM) utilizes two stage regulation to precisely deliver smoke or air at the approved EVAP test pressure of 12-14 inches of water column. The Total-Tech(TM) provides the operator with a pressure gauge as well as a flowmeter. These components allow the technician to test any system using pressure decay in seconds, and to visually detect the rate of leakage on the flowmeter. The Total-Tech(TM) also incorporates a Flow Control Valve. This valve also allows the technician the versatility to pinpoint a leak without the masking effect of excessive smoke. The Total-Techs(TM) compact design allows the unit to hang under the hood or chassis during testing. Machined from billet aerospace aluminum and stainless steel, the Total-Tech(TM) is made in America and unconditionally warranted for one full year.
