Description
Product Overview
Spirax Sarco OR60A is an automatic drain precision compressed air filter/regulator designed to condition supply air for industrial pneumatic equipment. The unit automatically extracts moisture and oil mist while maintaining stable downstream pressure to prevent damage and contamination in sensitive instruments.
Key Features
- Compact construction
- High-efficiency 0.01 µm filtration element with 99.9% capture efficiency
- Automatic drain design delivering high flow capacity and low pressure drop
- Quick-locking adjustment knob for output pressure setting
- Relieving metal bowl fitted as standard
- Additional models available within the series

Automatic Drain Operation
When a sudden change in airflow occurs or when supply pressure drops, a temporary spray-like discharge may take place from the automatic drain mechanism.
Applications
- Air bearings in industrial machinery
- Air metering equipment
- Instrument air supply circuits
- Fluid control systems
- Breathing air systems
