Screw Compressors Low-Pressure Air Compressor
Product details
Rotary Screw Technology: Utilizes advanced oil-injected airends with asymmetric helical profile rotors instead of pistons, providing smooth and continuous compression.
High-Efficiency Drive: Powered by High Efficiency Electric Motors and driven by high-performance L-profile Poly V-belts, ensuring maximum power transmission.
Massive Industrial Capacity: Available in a vast range of sizes, from small workshop units (0.29 m³/min) to massive industrial plants (up to 53 m³/min in the VSD series).
Clean & Safe Operation: Features a double-stage full oil separation system with an immersion-type separator and fire-retardant sound insulation.
Intelligent Protection: Comes standard with Phase and Motor Protection Relays, as well as high-pressure and high-temperature alarms/stoppers to prevent damage.
Ergonomic Design: Housed in an ergonomic cabinet designed for easy access and maintenance, minimizing downtime during service intervals.
Screw Compressors Low-Pressure Air Compressor
The Screw Compressor series represents state-of-the-art technology for low-pressure industrial air needs. Unlike reciprocating models, these units use oil-injected airends where air is compressed between two rotating rotors (lobes) with an asymmetric helical profile. This "screw" design is the heart of the compressor, providing maximum performance and durability.
Designed for continuous duty, they feature ergonomic cabinets with sound insulation and comprehensive safety systems, making them the ideal choice for facilities requiring reliable, high-volume air supply.
