Aerotec Presostato para compresores 4-8 bar, 230/400V, 16A, G 1/4" 9063048

This pressure switch for air compressors offers precise control of the switching pressure range from 4 to 8 bar, making it an essential component for reliable compressor operation. Its robust design and integrated unloader valve ensure smooth starts and protection of the compressor motor.

Advantages

The switch features an integrated unloader valve that releases pressure from the compressor head after shut-off, preventing motor overload on restart. The built-in ON/OFF switch provides convenient manual control, while the IP44 protection class ensures safe operation in dusty and damp environments. The high-quality plastic housing is durable and resistant to mechanical stress, and the 4-pole design with 16 A switching capacity supports both single-phase and three-phase motors.
