Diagnostic Smoke® Vapor Machine
Has Built-In Nitrogen-Generator
Part No. WV522B
The Same Machine that is Available to Several OEMs


VACUTEC® was the original smoke machine on the market many years ago and was the first machine to be approved by any OEM.  Now once again VACUTEC® brings the latest OEM technology to the Aftermarket.  This is the same machine that was recently designed and built in collaboration with several OEMs and has now been made available to you.  Utilizing the latest patented technologies, this VACUTEC® is the most advanced Evaporative Emissions (EVAP) System Tester available today. It is the only smoke machine in the Aftermarket with a built-in nitrogen generator; always delivering the machine's Diagnostic Smoke® vapor using clean dry high purity nitrogen. 

This Tester is the only smoke machine in the aftermarket approved for EVAP leak-testing of Flex-Fuel vehicles.  Recent university studies show that Flex-Fuel vehicles need special care when technicians perform EVAP leak-tests, due to the highly oxygenated and volatile nature of alcohol fuel vapors.  Special care must be taken never to add compressed air, containing oxygen, into the EVAP system since that can easily render the vapor space in the fuel tank combustible. 

A design originally requested by several OEMs; this VACUTEC® insures the delivery of clean dry high purity nitrogen and prevents the hazard of adding air into the vehicle systems. Simply connect the VACUTEC® to compressed air (shop air) and the machine's PSA nitrogen generator automatically converts the air to high-purity nitrogen, never running out of nitrogen. The tester's special Diagnostic Smoke® vapor is always delivered to the vehicle in a clean and safe inert medium. Its high nitrogen purity is guaranteed due to its computer-controlled nitrogen-purity monitors.

An added plus is that the nitrogen the Tester produces is always 'clean' and 'dry'.  New vehicle designs are susceptible to unwanted contamination, such as is present in 'shop air'.  Automakers today do not recommend introducing shop air into any vehicle system including; EVAP, induction, or any vacuum system.
