What's the differences between COLO powder coating guns?

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:

- COLO-191S series, KF-X1 series, KF-X2 series can be said the same, the only difference is the appearance of the control panel. 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.

- COLO-500star is the most basic model, suitable for extremely low budget, but not very recommended if you want a good powder coating sense.
