5.4 Additional included duct testing components
In addition to the calibrated fan and digital dual-channel pressure gauge, a Retrotec DucTester system
includes a few additional items.
5.4.1. Grill Mask for sealing registers
Grill Mask is used to seal over registers and vents. Grill Mask comes in a 12" wide roll.
It is perforated at 12" intervals to provide easy-to-tear pieces that can seal nearly
anything. Be careful applying Grill Mask to painted surfaces, as paint can be pulled off
when removing it after testing. Additional Grill Mask can be ordered from Retrotec as a
single roll or in three roll bundles. A handy Grill Mask dispenser is also available as an
optional accessory.
5.4.2. Umbilical for connecting fan and DM32 gauge
An umbilical neatly bundles the needed pressure tubes and Control Cable, to prevent
the user from being greeted by a tangled mess of tubes and cables before each test.
The standard 20' long DucTester umbilical includes a yellow, green, and blue
pressure tube, as well as the Control Cable used for the DM32 to communicate with
the fan. For detailed instructions on how to connect the DucTester fan and the
DM32 gauge using the Umbilical, refer to section 6.1.
5.4.3. Flange for connecting flex to ductwork at register
The Flange is the intermediate part used to secure the Flex Duct onto a return
register by using masking tape or Grill Mask. For instructions on how the Flange is
connected, refer to section
6.6 .
5.4.4. Toolbag keeps all testing components in one place
The Deluxe Cordura Tool bag provides enough volume to hold all the system
components of a DucTester System. It includes a shoulder strap for easy carrying.
The vented exterior pocket is an important feature, useful for storing your smoke
puffer which will destroy your gauge and laptop if stored together.
5.4.5. Tubing Accessory Kit
The Tubing Accessory Kit comes with blue pressure tubes. Attaching a Static
Pressure Probe to the pressure tube can prevent pressure reading interferences
from wind or other air flows blowing on the pressure tube. The metal tube can
be passed through a small such as under a door or window to prevent the tube
from being pinched, and affecting the pressure reading.
