The new generation CompAir L45–L55 with innovative FourCore technology delivers up to 10% higher airflow and up to 12% lower energy consumption compared to conventional solutions. Two-stage compression in an extremely compact design provides rapid return on investment – in some cases in less than one year.
The patented FourCore design combines one motor and four rotors within a single semi-integrated housing. The result is higher efficiency, constant interstage pressure, fewer components, reduced leakage, and simplified maintenance compared to traditional two-stage compressors.
The L45–L55 compressors provide the advantages of two-stage compression in the size of a single-stage machine. They occupy only approximately 1.4 m² of floor space, resulting in up to 40% smaller footprint and easier integration into existing compressor rooms.
Variable speed versions precisely adapt airflow to actual system demand. This reduces unloaded running, enables up to 35% energy savings, and significantly lowers total cost of ownership under fluctuating load conditions.
The intuitive DELCOS XL SE touchscreen controller with integrated sensors optimizes operation according to real operating conditions. The system is iConn-ready, enabling remote monitoring, predictive maintenance, and increased reliability and equipment availability.
Highly efficient motors (IE4 for fixed speed, IE5 permanent magnet motor for RS versions) combined with heat recovery capability for space heating or process water applications enable up to 75% energy savings and a significant reduction in CO₂ footprint.
Fewer pipes, fewer joints, and a robust industrial design reduce the risk of leaks and failures. CompAir provides up to 12 years warranty on the airend within Assure service packages, resulting in lower maintenance costs and increased investment security.
