Refrigerated compressed air dryer WDF 70

in-linecompact

Product overview
The WDF 70 refrigeration dryer reduces moisture in compressed air by condensing and removing condensate while providing fine cleaning through two-stage filtration. It is designed for compressed air installations with moderate flow requirements.

Features and benefits

• Two-stage filtration: 1 µm and 0.01 µm filters remove solid particles and oil aerosols.
• Nominal capacity: 70 m³/h (1.16 m³/min) suitable for medium-demand systems.
• 1/2\" connection for easy integration with existing compressed air networks.
• Maximum working pressure: 16 bar; pressure drop: 250 mbar to ensure efficient operation.
• Power supply: 230 V / 1 / 50 Hz. Refrigerant: R134a.
• Compact housing for straightforward installation in limited spaces.
