  • Maintenance kits for Graco pump units that require cooled compressed air
  • High-use or long-duration spraying applications where heat buildup could impair performance

Frequently Asked Questions

It cools down compressed air coming from the compressor, lowering temperature before the air enters system components. This helps reduce wear, prevents overheating, and improves overall pneumatic stability.

While aftermarket coolers may work, using the OEM 15B815 ensures compatibility, proper mounting, and thermal performance specific to Graco systems.

Replacement involves uninstalling the old cooler from the air-supply manifold, mounting the new 15B815 using the same screws, and ensuring air lines are properly connected and sealed.

Periodic inspection for dirt and debris is recommended. If airflow is restricted, clean or replace the cooler to maintain optimal cooling efficiency.
