Two-piston compressor K 300-700 14 bar 5.5 HP/4 kW 400V 450 l/min 300 l

The K 300-700 compressor by Airpress is an efficient, two-piston piston unit designed for intensive tasks in industrial environments. Equipped with a 5.5 HP (4 kW) engine and a 300 liter tank, this compressor offers a capacity of 450 l/min at a maximum working pressure of 14 bar. Thanks to its solid construction and the use of modern technological solutions, the K 300-700 compressor ensures stable and reliable operation over long work cycles.

Key technical advantages:

  • Two-stage compression pump: The K 300-700 compressor is equipped with a two-stage compression pump, which allows for high efficiency at a stable operating pressure of 14 bar. The two-stage compression process ensures better efficiency and longer durability of the device, especially in intensive work cycles.
  • Low speed (800 rpm): The compressor operates at low speed, which reduces mechanical wear and extends the life of the device. Additionally, the low noise level (75 dB(A)) makes working in its surroundings more comfortable.
  • Capacity 450 l/min: Thanks to its high efficiency of 450 liters of air per minute, the K 300-700 compressor is perfect for intensive industrial applications that require a stable supply of compressed air to power pneumatic tools and machines.
  • 300 l tank: A solid tank with a capacity of 300 liters ensures long-term operation of the compressor without the need to frequently top up air. Made of high-quality materials, the tank complies with CE and AD 2000 standards, which guarantees safety and reliability when working under pressure.

Advanced technological features:

  • Interstage cooling system: The K 300-700 compressor is equipped with an interstage and output air cooler, which effectively reduces the temperature of the compressed air, improving its quality and protecting the device against overheating during long-term operation.
  • Ease of maintenance: The unit is designed for easy maintenance, allowing quick access to key components such as V-belts and air filters. The use of a V-belt tensioner on the engine crane further reduces maintenance time and increases the efficiency of technical service.
  • Condor pressure switch: The compressor is equipped with a Condor pressure switch that precisely monitors the operating pressure and also protects the engine against overheating, ensuring safe and reliable operation of the device in intense conditions.
  • Condensate drainage system: A special condensation valve placed in the tank allows for quick and effective removal of excess moisture, which prevents corrosion and extends the life of the device.

Uses:

The K 300-700 compressor is an ideal solution for industrial applications, such as car workshops, machine services and production plants, where high working pressures and a stable supply of compressed air are required. It is perfect for applications requiring high performance, such as powering CNC machines, pneumatic tools and performing maintenance work.
