Graco 116521 – Air Filter / Regulator
The Graco 116521 Regulator Filter Air is a combined air‑filter and pressure regulator unit. It delivers clean, moisture‑ and particle‑free compressed air, while regulating air pressure to maintain stable performance in pneumatic and spray systems.
Key Features & Specifications
- Inlet / Outlet Threads: 3/4″ NPSM (inlet, female) → 3/4″ NPT (outlet, female)
- Pressure Range: 5–125 psi (0.3–8.6 bar)
- Filter Element: 40‑micron polypropylene — filters out particles & moisture before air reaches downstream equipment
- Durable Construction: Built for industrial and spray‑coating environments; compatible with standard 3/4″ fittings
- OEM Quality: Genuine Graco part ensures proper fit, sealing, and performance reliability
Compatible Systems / Applications
- Graco pneumatic pumps, sprayers, or proportioning equipment requiring regulated air supply
- Air‑motor driven spray systems that list 116521 (or equivalent air‑filter/regulator) in their air‑control assemblies
- Industrial painting, coating, and fluid‑handling setups using compressed air and needing moisture/particle filtration
Note: Always verify that your equipment’s air‑line configuration uses 3/4″ inlet/outlet and requires a filter/regulator — check the parts manual or air‑control schematic prior to installation.
Why Use 116521?
- Ensures clean, contaminant‑free air — protects internal pump and spray components from wear, clogging, or damage
- Provides stable, adjustable air pressure — critical for consistent spray quality or pump performance
