K Series
Airpress K Series industrial compressors are advanced piston compressors designed for high-performance applications in industrial environments. They offer reliability, efficiency, and durability, making them suitable for demanding conditions where long service life and stability are essential. Equipped with low-speed two- or four-piston pumps and operating pressures of up to 14 bar, K Series compressors are ideal for tasks requiring steady performance at high pressure – such as in tire service centers, auto workshops, and CNC machine operations.
Innovative features like thick-walled, corrosion-resistant tanks, low RPM operation, and a star-delta starting system ensure long life and reduced operating costs. Additionally, sturdy transport handles and robust wheels make it easy to move the compressor to various work locations, which makes these units a great choice for on-site tasks. Airpress K Series compressors are a reliable alternative to screw compressors, offering users enhanced performance, safety, and work comfort.
Key Advantages and Innovations of Airpress K Series Industrial Compressors
- High-performance compressor pumps and low rotation speeds allow long duty cycles (from 60%-40% up to 70%-30% depending on conditions). K Series compressors are highly overload-resistant, ensuring reliable performance even under heavy use.
- 14-bar low-speed compressors with two- or four-piston, two-stage pumps, designed for higher pressure operation. Ideal for tire services, auto workshops, and industrial plants powering CNC machines, cutting, welding, or assembly tools.
- Thick-walled corrosion-resistant pressure tanks enhance durability and are designed for heavy-duty high-pressure tasks.
- Reduced rotation speeds (740–1020 RPM) extend compressor life and allow safe, continuous 24/7 operation.
- Advanced Condor pressure switch with thermal protection ensures the highest level of safety during operation.
- Easy maintenance with crane-mounted motors – quick access to the belt tensioner simplifies service procedures.
- Mobility and ease of transport thanks to ergonomic handles on both sides of the tank – combining the benefits of a stationary unit with on-site flexibility.
Applications of Airpress K Series Industrial Compressors
K Series low-speed compressors are widely used across industries where constant, high-pressure air supply is essential, regardless of work intensity. They are perfectly suited for tire and automotive service centers, capable of handling trucks, agricultural machinery, and construction equipment thanks to their 14-bar pressure capacity. They are also ideal for powering CNC machinery used for cutting, welding, or assembly, and for demanding cleaning tasks using high-pressure air. The robust construction, mobility, and ability to run 24/7 make the K Series a reliable solution wherever maximum performance and durability are required.
Specialized Models with Star-Delta Start System
The K Series is also available with star-delta start modules (Y-Δ), equipped with an hour meter and check valves supported by an additional solenoid relief valve. Once the tank is filled, the compressor system is instantly depressurized, reducing startup time and improving ease of use.
High Performance and Reliability
K Series compressors feature high-efficiency compressor pumps operating at low speeds, allowing long duty cycles (from 60%-40% to even 70%-30%). Built for heavy-duty tasks, they ensure maximum durability and overload resistance, even in high-demand settings.
Two-Stage Compressors
With low-speed, 14-bar, two-stage pumps (two or four pistons), K Series compressors offer reliable high-pressure performance. Ideal for tire and automotive workshops, as well as industrial applications requiring robust air supply – especially for powering CNC machines and pressure-sensitive tools.
Durability and Operational Safety
K Series compressors are equipped with thick-walled, corrosion-resistant pressure tanks. Their low rotation speeds (740–1020 RPM) allow for uninterrupted 24-hour operation, extending service life. The Condor pressure switch with thermal protection enhances operational safety, and crane-mounted motors make maintenance and servicing more convenient.
Mobility and User Comfort
Models in the K Series are designed with ergonomic handles on both sides of the tank, ensuring easy mobility and dual-purpose use – both stationary and portable. The star-delta start module with hour meter increases efficiency, helping monitor runtime. Check valves with solenoid discharge improve restart speed and simplify use in demanding conditions.
Quality Assurance and Performance Testing
Every K Series compressor undergoes rigorous performance, durability, and efficiency testing at a working pressure of 21 bar. These tests guarantee top-tier reliability and industrial-grade performance, making K Series compressors the go-to solution for users with the highest demands.
