The easiest way to maximize spray performance is to use Graco brand strainers and filters in your sprayers and guns. A strainer prevents foreign objects from entering into the pump and provides the first stage of filtration.
Pump inlet filters help prevent debris from being suctioned into the pump, causing damage to your sprayer.
Thorough cleaning after each use will increase strainer life. We recommend thoroughly cleaning ALL spray painting equipment after EVERY use as most of the repairs we do are directly related to not cleaning or not cleaning completely.
