What is the Graco Fast Flush 2?

Fast Flush 2 is a cleaning feature installed on many of Graco’s current airless pumps. This feature allows the sprayer to be cleaned quickly and thoroughly.

To do this, the airless operates at full motor power and pushes water or other cleaning fluid through the system.

How to use the Graco Fast Flush 2?

First, the residual paint must be pumped out of the airless device and the hose using the low pressure flush function.

Then the Fast Flush 2 function can be used for rinsing. In these photos, we worked with a water-soluble wall paint. So we rinsed the unit with water.

What are the mistakes to avoid with the Graco Fast Flush 2?

The Fast Flush function should only be used for cleaning, i.e. rinsing. It should not be used for spraying paint, plaster or other materials. The sprayer would then be overloaded in continuous operation. In addition, the application of the material could be uneven.

Care should also be taken to ensure that the Fast Flush function is not inadvertently triggered. After the flush function (Prime/Slow, with little pressure), the Fast Flush function is positioned before the “Spray” button. Especially for new users, the Fast Flush function may be activated by mistake.

It also happens regularly that the pressure control knob is not adjusted correctly and the Fast Flush function already starts while the pressure regulator is still on Prim/Slow, i.e. on Rinse.
