In the course of applying an ergonomic design throughout, we also achieved a 5-g weight reduction. Every adjustment knob is tapered with deeper grooves, providing a surer grip for easier fine adjustments. We also built in a bushing into the back of the needle valve spring to make paint output adjustment smoother. The tip of the trigger has a smoother shape, for easier operation when applying lower paint volumes.
The new WIDER is designed for easier maintenance. We changed the thread pitch of the cap from 1.0 mm to 1.5 mm, so that it can be screwed on with 1.5 turns, which is half as many as before. Also, the back end of the needle valve is reshaped to make it easier to remove and attach. By adding straight threadless sections to the air and fluid nipples, we made it easier to attach the connectors.
The previous pattern adjustment set reached around 45% of full pattern width with 1 turn, around 80% with 1.5 turns, and almost 100% or nearly fully open with 2 turns. Our newly-developed pattern adjustment set now provides around 35% with 1 turn, around 50% with 1.5 turns, and around 70% with 2 turns. This linear response to adjustment is intuitively easier to operate.
Previous air valve seat sets consisted of a combination of large and small orifices in the air channel, so installing it into place could produce differences in air volume due to its’ position. This difference could potentially influence paint output and pattern width. We revised the design for the new WIDER, making the orifices much larger and more uniform so that installing the air valve seat set in produces more repeatable results. That enables even more consistent application.
