Two-piston compressor K 500-1000S 14 bar 7.5 HP/5.5 kW 400V 481 l/min 500 l - star-delta connection

The K 500-1000S compressor by Airpress is an industrial piston compressor with a maximum working pressure of 14 bar, designed to work in demanding conditions. It has been designed to operate in intensive work cycles, offering a capacity of 481 l/min and equipped with a tank with a capacity of 500 liters. The design based on a two-stage compression pump and a star-delta connection system ensures efficiency, durability and reliability, especially in industrial applications where stable operation at high pressure is required.

Key technical advantages:

• K30 two-stage compression pump: The K 500-1000S compressor is equipped with a two-stage compression pump that guarantees stable air compression. The two-stage system allows for high pressures at lower revolutions, which improves the efficiency and durability of the device.
• Low speed (900 rpm): Thanks to the low engine speed, the compressor runs quieter and uses fewer components, which translates into its long life.
• Star-delta connection: The star-delta starting system minimizes the starting current, which ensures a smooth start of the compressor and reduces the risk of overloading the electrical installation.
• Efficient cooling system: The compressor is equipped with an interstage and output air cooler, which lower the temperature of the compressed air, improving its quality and extending the life of the device.
• Solid 500 l tank: A 500-litre tank made of thick-walled materials, adapted to work under high pressure, withstands working pressures up to 16 bar, which guarantees operational safety and durability.
• Capacity 481 l/min: The compressor provides a stable amount of compressed air, which makes it suitable for working with pneumatic tools and machines requiring high air pressure.

Advanced technological features:

• Precise control: The Condor pressure switch with thermal protection monitors the pressure and protects the motor from overheating, ensuring safe and stable operation of the compressor.
• Easy maintenance: The sliding design of the engine allows quick access to the V-belt tensioner, which significantly facilitates their adjustment and replacement, reducing maintenance time.
• Acoustic noise control: The used air filter with a modified structure effectively reduces the noise level, which increases the comfort of working in the compressor environment.

Uses:

The K 500-1000S compressor is an excellent choice for car workshops, industrial machinery services and production plants where high efficiency and reliability are required. Its efficiency and durability allow it to power CNC machines, pneumatic tools and perform intensive tasks requiring high compressed air pressure.
