BPI Mini Gradient has a continuous 4-Stroke process without a timer. It will continue to cycle until it is turned off. It is simple to use and can be adapted to any unit. BPI Mini Gradient is made of 100% low maintenance stainless steel. The BPI Mini Gradient is UL listed (USA Underwriters Laboratory) and meets or exceeds the European CE and Canadian CUL standards. The BPI Mini Gradient has a one year warranty. In the 4-Stroke gradient process, the lenses are lowered further into the dye on each stroke. After the fourth stroke the gradient repeats the cycle. This mechanical process creates a smooth gradient effect.

Mounting flange:

If the Gradient is not to be used with a BPI tinting machine, then please check the option "With mounting flange" so that the gradient unit can be mounted to a surface supplied by the user.

If the Gradient will be used with a BPI tinting machine, then the gradient unit can be inserted directly into a hole in the back of the tinting machine, and you should click the option "No mounting flange."
