PressurePros 249 Report post Posted June 4, 2007 I picked up a YRL-55 spray gun from Paul Kassander at Envirospec North after some advice from Michale Kriesle about using one with better flow (larger orifice inside). Do you want more flow from your gun? More chemical draw? I was blown away at the difference. You can really feel it on a 5.6 gpm machine. The soap flows like a river. Even without the soap injection, the flow seemed higher. The guns I have been using were not cheap but they must have been restrictive. If you are looking to try one out and see for yourself, Paul has them listed here. Envirospec North 877-351-1238 (scroll down to the blue ones) Share this post Link to post Share on other sites
