McGill Leak Detective® Test Kits:
Why Test for Leakage?
No duct system is airtight.
All leak to some degree. If controlled, duct leakage can be less than 1 percent of the
total system cfm. As leakage increases, more air and energy is required to maintain design
conditions, and this increases operating costs.
Standard Leak Detective® Test Kits
A McGill Leak Detective test kit makes it easy for you to measure duct system leakage. We offer four standard sizes, each available either as a kit or mounted on a wheeled cart. Other sizes are available as nonstandard items. Leak Detective carts, orifice tubes, and test kit components can be ordered individually. A standard leakage test kit consists of the following equipment:
1. Calibrated orifice tube
The standard test kit contains a 4-, 5-, 6-, or 8-inch orifice tube calibrated for positive pressure system testing. The fans, which come with an inlet damper control, can be ordered for 110- or 220-volts and 50- or 60-cycle current.
