Why Dry Air Matters
The Cooper DryFlo DX400-AC’s aftercooled system with integrated water separator ensures your compressed air is dry, clean, and reliable — a critical advantage for industries where moisture can cause costly problems.
- Abrasive Blasting & Surface Prep – Prevents abrasive media clumping, maintains consistent blasting pressure, reduces flash rust, and keeps visibility clear inside blast chambers.
- Painting & Coating – Eliminates moisture that causes paint defects and poor powder coat adhesion, ensuring flawless finishes every time.
- Manufacturing & Production – Protects pneumatic tools and valves from corrosion, reduces wear, and maintains consistent air pressure for precision work.
- Food & Beverage Processing – Prevents bacterial growth and clogs in pneumatic conveyors, keeping packaging and ingredient transfer safe and efficient.
- Electronics & Semiconductor Manufacturing – Avoids condensation that can damage components, ensuring cleanroom compliance and product reliability.
- Pharmaceuticals & Medical – Protects product purity in capsule filling, tablet coating, and cleanroom operations, meeting GMP standards.
- Pneumatic Tools & Equipment – Extends tool life, maintains efficiency, and avoids costly downtime.
- Energy, Mining & Oil/Gas – Stops ice blockages and corrosion in instrument air systems, even in harsh, remote environments.
Bottom line: Dry air means better quality, less downtime, and longer-lasting equipment — making the DX400-AC the smarter choice for high-performance industrial air.
