Custom Duct Marker

Custom Duct Markers are easy to design online and give you the exact wording you are looking for. Although we have a large inventory of stock duct markers, sometimes you need the wording to be slightly non-standard on your duct marker. These are easy to apply adhesive backed markers that include your custom wording plus an arrow in your choice of 3 different color combinations.

Marker Colors

Color is the secondary means to identify the contents of a piping system but, many times the most important. The color of the marker should be used to identify the characteristic hazard of the contents of the pipe.

Install duct markers with permanent adhesive on air ducts in the following color codes:

  • Green: For cold-air supply ducts.
  • Yellow: For hot-air supply ducts.
  • Blue: For exhaust-, outside-, relief-, return-, and mixed-air ducts.

Installation Guide

Brimar recommends the following locations for installation of duct markers:

  • Locate duct markers where ductwork is exposed in finished spaces; machine rooms; accessible maintenance spaces such as shafts, tunnels, and plenums; and exterior non-concealed locations as follows:
  • Near each damper.
  • Near each branch connection. Mark flow direction at each branch.
  • On both sides of penetrations through walls, floors, ceilings, and non-accessible enclosures.
  • At access doors, manholes, and similar access points that permit view of concealed ductwork.
  • Near major equipment items and other points of origination and termination.
  • Spaced at maximum intervals of 50 feet along each run. Reduce intervals to 25 feet in congested areas where ductwork is partially hidden by other pipe, ductwork or equipment.
  • On both sides of every change in direction.
  • When several ducts from different units are located in concealed congested areas, locate identification at air handling unit, at each side of penetration of structure or enclosure, and at each obstruction.
  • Provide a minimum one label per pipe per room. Where pipes are racked, install pipe markers on each pipe in the same location to aid in differentiating each pipe in the rack.
