Retrotec 451 110V hire kit | Duct leakage tester

Contact Instrument Solutions

The Retrotec 450 series are small yet high power positive and negative duct leakage testers which can test systems to pressures beyond 5 kPa. Used with the DM32-20 smart test gauge with touchscreen LCD, this system is intuitive to setup and use.

With a fan weighing just 9 kg, and the full kit in its case weighing only 16 kg, this duct leakage tester is a truly portable system allowing the engineer access to test points other units will not allow.

Features

  • Fast automatic documentation with simple to use software that creates custom reports with your company logo. (June 16 - Free of charge Beta version of the software is available to download only from www.retrotec.com only)
  • The 450 series DucTesters can be run directly via the DM32-20 smart gauge which contains all the formula needed to calculate the applicable test standard leakage parameters .
  • Wireless capability enables the fan to be run via your iPhone or Android device

Common customer questions & answers

QQuestion There is no power on the construction site so can this unit be run off a generator?
AAnswer No. If you run this item off a generator it is possible to damage the fan motor.
QQuestion The fan power on the Retrotec 451 ramps up and down and doesn't appear to be a steady flow - why might this be?
AAnswer 1. Check the duct system being tested, and internal or external door/flap may be moving and affecting pressures and therefore the fan power is reacting to this. 2. You may need to carry out a manual test rather than an AutoTest/Semi Autotest. Increase the power slowly to the desired pressures. If using AutoTest in a tight system sometimes the unit can't find the medium to settle at and keeps trying by applying or reducing power.
