Many powder coating users are curious about the differences between COLO's many types of powder coating guns. Pls refer to the below form to compare.

Let me make summaries:

The functions, configurations and other features are all same, which type you buy depends on which appearance you like. They are in the highest level performance of COLO guns, as well as the price.

- COLO-800D series & KF-K1 series are same, except the appearance.

- COLO-660 series & COLO-668 series are in same functions and configurations, except the appearance and the moveable trolley.

- Comparing with COLO-800D, COLO-660 has one more pre-set application program, which is PULSE-coating mode. But many customers give feedback that the function of COLO-800D is enough. 

- Another difference is the trolley, as the COLO-800D's trolley is more table and flexibile, it requires more packing size. Thus the freight cost of COLO-800D series is a lot higher than COLO-660 & COLO-668. 

- Each of COLO Powder Coating Gun is proved with reliable performance and quality by worldwide users, which model to buy demands on your budget, pursue of powder coating experience, etc.
