Why Dry Air Matters

The Cooper DryFlo DX275-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.
