The K 300-700S compressor by Airpress is an advanced piston compressor designed for intensive industrial tasks. 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. Additionally, the device is equipped with a star-delta starting system, which ensures a smooth start, reducing the load on the electrical installation. K 300-700S is a perfect solution for production plants and services requiring a continuous and stable supply of compressed air.

Key technical advantages:

• Two-stage compression pump: The K 300-700S 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 higher efficiency and allows for long-term operation without the risk of overheating.
• Low speed (800 rpm): The compressor operates at low speed, which reduces mechanical wear of components, extending their life. Additionally, the low noise level (75 dB(A)) ensures comfortable work in its surroundings.
• Star-delta starting system: The K 300-700S compressor is equipped with a star-delta starting system, which reduces the starting current, enabling a smooth start of the device. Thanks to this solution, the risk of overloading the electrical installation and failure is reduced.
• Capacity 450 l/min: The compressor offers a capacity of 450 liters per minute, which makes it ideal for applications requiring large amounts of compressed air, such as powering pneumatic tools and CNC machines.
• 300 l tank: A solid tank with a capacity of 300 liters ensures long-term operation without the need to frequently refill air. The tank design meets CE and AD 2000 standards, which guarantees safety and reliability when working under pressure.

Advanced technological features:

• Interstage cooling system: The K 300-700S 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 intensive operation.
• Ease of maintenance: The compressor design allows easy access to key components such as the V-belt, making maintenance easier and reducing service time. Additionally, the V-belt tensioner mounted on the engine crane speeds up the adjustment and replacement process.
• Condor pressure switch: The compressor is equipped with a pressure switch from the renowned Condor brand, which precisely monitors the operating pressure and protects the engine against overheating, ensuring safe and reliable operation of the device.
• 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.
