Spirax Sarco FR20A automatic-drain high-efficiency compressed air filter/regulator effectively removes moisture from compressed air while providing high-quality compressed air and precise pressure control for pneumatic actuators and other applications.

Key Features

• Compact design

• Filter/regulator suitable for a wide range of applications

• High-performance design provides high flow rates and low pressure drop

• Adjustment knob with quick-lock function

• Standard option includes an overpressure-type transparent bowl

• Other models available

Applications

Provides high-quality compressed air. Many applications require high-quality compressed air, including air bearings for machinery, air gauging equipment, instrument air supply, fluid systems, breathing air, and pneumatic positioners.

Flow Characteristics

Medium: Compressed air

Maximum inlet pressure: 10 bar g

Ambient temperature: ℃ - +50℃ (when the temperature is below +2℃, the air must be sufficiently dry to prevent freezing)

Filter element: 5μm

Air quality: ISO 8573-1, class 3 and class 5

Flow rate (at an inlet pressure of 10barg and set pressure): 6.5dm³/s

Typical flow rate: None

Port size: ISO G1/4

Pressure gauge connection: 1/8 ISO RC

Outlet pressure adjustment range: 0.3 - 7 bar g

Automatic drain operation: Spray-type drainage may occur temporarily when the air flow changes rapidly or the supply pressure decreases.
