What to do if Graco EcoQuip 2 EQp blast spray pattern is sputtering?
- AAdrienne GordonAug 18, 2025
If the blast spray pattern is sputtering or irregular, several factors could be responsible. First, ensure that your air compressor meets the minimum flow requirements and that the air inlet pressure gauge reads between 100-150 psi. Clean or replace the air inlet filters if needed. Also, verify that the blast hose was properly cleaned after previous use and that the abrasive metering valve setting is appropriate for the blast pressure and abrasive type. Ensure the pot has enough abrasive. Check the nozzle for blockages, buildup, or damage and replace if necessary. Inspect the pot and abrasive hose for obstructions, and close the fill/flush valve if it's open.
