The Vacutec WV622N Nanotube Fiber N2 Smoke Machine produces an endless supply of nitrogen for safer EVAP testing without the time or cost of changing nitrogen cylinders or CO2 canisters. The user simply connects the unit to the shop air supply and the machine does the rest. This revolutionary space-saving design is the smallest nitrogen generator ever invented, says the company, for these types of applications, and features a nanotube built into the unit’s handle. It has a much smaller footprint and lighter weight than models requiring a nitrogen generator. This durable, cutting-edge technology assures the user an endless supply of nitrogen for the lifetime of the smoke machine. The WV622N includes other features including the ability to quantifying leaks with pressure decay (PSI/bar) and flow rate, and UltraTraceUV smoke solution, which deposits a non-contaminating dye at exact leak locations and, which finds leaks smoke alone cannot.
