The TC Wilson Vacuum Leak Detector (VLD) is a simple test instrument used by manufacturers and users of condensers, heat exchangers and other tubular apparatus to identify leaky tubes.
HOW TO USE THE VLD
- One man does the job.
- He seals the far end of each tube with a snap type tube plug, then he presses the rubber coated nozzle into the near end of the tube and depresses the trigger.
- Compressed air flows through a Venturi chamber to produce a vacuum in the tested tube.
- When this vacuum reaches a satisfactory level, he releases the trigger.
- A steady Gauge reading indicates a good tube.
- A falling vacuum indicates a leaky tube.
Using a 90 PSI dry clean air, a typical tube (based on 1″ OD x 20 Gauge and 20′ L tube) can be tested in 6 to 8 seconds. Tool weighs 2.25 lbs. and is equipped with a muffler, so it operates quietly even in confined areas.
