Iwata W-400 vs WIDER4 vs WIDER4L Spray Gun

It all started 66 years ago (1957) when the company Anest Iwata launched its first WIDER spray gun model (model: W-57). The models W-101, W-200 and W-400 followed. Based on the great success of these models, Iwata launched the WIDER1 and WIDER2 in 1997 as an evolution of the W-101/W-200. And more recently, the company has introduced the Iwata WIDER4 spray gun range, based on the very popular Iwata W-400. This article provides information and comparisons between the Iwata W-400 and WIDER4, Iwata W-101 and WIDER1, Iwata W-200 and WIDER2, Iwata LPH-400 and WIDER4L spray gun models.

Features of Iwata WIDER1, WIDER2 and WIDER4

• Spray gun body: complete re-design
• Trigger re-design: The new trigger shape allows finer trigger control which helps when applying lower paint volumes
• Tapered knobs (deeper grooves): better grip for easier fine adjustments
• Bushing at back of needle: smoother paint output adjustment
• Air cap locking: air cap can be screwed on with only 1.5 turns (about half as many as before)
• Finer spray pattern width adjustment: previous pattern adjustment set reached about 45% of full pattern width with 1 turn and about 80% with 1.5 turns. The new pattern adjustment set now reaches about 35% with 1 turn and about 50% with 1.5 turns.
• HVLP versions available: ‘L’ in the model description indicates that the gun has HVLP atomization
