Mounting Cleanfit CPA871
24 Hauser
Pneumatic connection for automatic operation
Prerequisites:
• Air pressure 4 to 7 bar (absolute pressure) (58 to 102 psi)
• Compressed air quality in accordance with ISO 8573-1:2001
Quality class 3.3.3 or 3.4.3
• Solids class 3 (max. 5 μm, max. 5 mg/m 3 , contamination with particles)
• Water content for temperatures ≥ 15 °C: Class 4 pressure condensation point 3 °C or lower
• Water content for temperatures of 5 to 15 °C: Class 3 pressure condensation point -20 °C or
lower
• Oil content: Class 3 (max. 1 mg/m 3 )
• Air temperature: 5 °C or higher
• No continuous air consumption
• Minimum nominal diameter of air pipes: 2 mm (0.08 ")
A dual-operating cylinder is used to operate the pneumatic drive.
An automatic limit position lock both in service and measuring position secures the assembly
to prevent it from moving inadvertently in the event of a failure in the control air. The
assembly remains in the relevant position.
Connection: Push connector M5, hose 4/2 mm OD/ID (adapter for 6/4 mm OD/ID enclosed)
NOTICE
Air pressure too high
Damage to seals.
‣
Connect a pressure-reducing valve upstream if the air pressure is likely to rise to above 7
bar (absolute pressure) (102 psi) (even short pressure surges).
