Step 1
Look for the unique, trademarked, muted green color that Sullair uses to paint its products. Every part of a Sullair product is usually painted this particular color, except for rounded air tanks, which are painted flat black.
Step 2
Look for the flat black framing that Sullair uses on its products. Every Sullair unit is painted with a flat black frame or border around all of its edges. Vents and handles are often painted with this color as well to stand out against the green color of the unit.
Step 3
Look for the "Synergy" label on the unit. The "S" on the label will be bigger than the other letters in the word and will be printed in a cursive-style font, while the other letters are printed using a more squared-off and italicized font.
Step 4
Locate the serial number on the unit and contact the Sullair company (see Resources) to verify that the product is actually one of Sullair's and not a counterfeit.
