I have been using Apollos products now for almost 7 years and I can say without a doubt that they build some quality products. I currently own a 2−½ gallon pressure pot and a 7500 atomizer gun and have sprayed many cabinets with many different materials and have always been satisfied with the end results. I very recently was able to use their precision 5 turbine that a general contractor had available on the job to spray some coffered ceilings and some cabinets with pre-cat lacquer… Sweet. I am definitely going to invest in this precision 5 turbine. I was able to dial that turbine in with the turn of a knob to the precise pressure needed for that application. It is extremely user friendly. If your a painting contractor, one of their setups is a no brainer to have in your arsenal of spray equipment. I love how the turbine unit is so portable and had a dedicated spot for your gun to sit. Keep up the good work Apollo!
