Two-piston compressor K 500-700S 14 bar 5.5 HP/4 kW 400V 450 l/min 500 l - star-delta connection

The K 500-700S compressor by Airpress is an industrial piston compressor with a maximum working pressure of 14 bar, dedicated to applications requiring stable operation under high load. It has been designed with intensive work cycles in mind, offering a capacity of 450 l/min and equipped with a 500 liter tank. Its design, based on a two-stage compression pump, ensures high durability and reliability, which makes it an ideal solution for workshops, industrial plants and machine services that require continuous operation under high pressure.

Key technical advantages:

• K30 two-stage compression pump: The K 500-700S compressor is equipped with a two-stage compression pump that guarantees stable air compression. Thanks to the two-stage compression system, the air passes through two phases, which increases its efficiency and allows for higher pressures at lower revolutions.
• Low speed (900 rpm): Low engine speed ensures less wear on components, which translates into longer compressor life and quieter operation.
• Star-delta connection: The star-delta starting system minimizes the starting current, which ensures a smooth start of the compressor and reduces the load on the electrical installation, reducing the risk of overloads and preventing the formation of current peaks during starting.
• Effective cooling system: The compressor is equipped with an interstage and after-air cooler, which significantly reduces the temperature of the compressed air, improving its quality and extending the life of the working elements. Additionally, a large pulley with enlarged blades ensures optimal cooling of the pump.
• Robust 500 l tank: The thick-walled tank with a capacity of 500 liters is designed to operate at high operating pressures (up to 16 bar) and is equipped with safety valves in accordance with CE and AD 2000 standards, which ensures safe operation even in the most difficult conditions.
• Capacity 450 l/min: The compressor provides a stable supply of air with a capacity of 450 liters per minute, which allows you to power a variety of pneumatic tools and machines that require a continuous and stable source of compressed air.

Advanced technological features:

• Precise control: The Condor pressure switch with thermal protection monitors the pressure and protects the motor against overheating, which ensures safe operation in long cycles.
• Easy maintenance: The K 500-700S compressor has been designed with easy maintenance in mind. The use of a sliding engine design allows quick access to the V-belt tensioner, which facilitates replacement and adjustment of the drive.
• Acoustic noise control: The inlet air filter with a modified design effectively reduces the noise level, improving the comfort of work in the compressor environment.

Uses:

The K 500-700S compressor is an ideal solution for car services, truck workshops and industrial production plants where continuous operation at high air pressure is required. Its performance and reliability allow it to power CNC machines, pneumatic tools and perform intensive maintenance tasks, such as blowing with compressed air or powering devices with high pressure demand.
