  • Maximum Air Volume: Delivers exceptional air flow rates, capable of reaching up to 55 m³/min (at 7 bar) in the largest models, supporting entire factory lines.

  • Advanced Screw Technology: Equipped with state-of-the-art oil-injected airends featuring asymmetric helical rotors ("screws"), designed to provide maximum performance and durability.

  • Robust & Protected: Comes standard with Phase and Motor Protection Relays, as well as high-pressure and high-temperature alarms/stoppers to ensure operational safety.

  • Quiet & Accessible: Housed in an ergonomic cabinet with fire-retardant sound insulation, designed for easy access and maintenance.

  • Clean Output: Features a double-stage full oil separation system with an immersion-type separator to minimize oil carryover.

Direct Drive Series Low-Pressure Air Compressor

The Direct Drive Series represents the pinnacle of low-pressure screw compressor performance. Unlike piston compressors, these units utilize oil-injected airends where air is compressed by two rotating rotors. This "screw" design is the heart of the compressor, ensuring smooth, continuous operation.


Designed for high-demand environments, the Direct Drive Series combines state-of-the-art technology with an ergonomic, sound-insulated cabinet. It is the ideal choice for large-scale industrial facilities requiring reliable, high-volume compressed air.
