Piston compressor E-Bull

portablelow energy consumptionoil-free

Overview
The E-Bull is an electric, oil-free piston compressor series designed for commercial vehicles, rail vehicles and industrial installations. The latest generation focuses on low weight, improved efficiency (approx. 10.6 W per l/min in the most efficient configuration), quiet operation and flexible installation positions. Oil-free, low-friction technology and corrosion-resistant materials reduce maintenance needs and service costs.

Robust & durable

• New: optimized heat dissipation via rotatable compressor heads
• Designed to withstand strong vibrations, suited for mobile applications
• High ingress protection: IP67 (dust- and water-resistant)
• Long service life due to oil-free design and durable materials
• Operating temperature range: -40 °C to +50 °C

Compact & quiet

• New: reduced installation height with integrated/internal airflow
• Multiple installation orientations possible (rotatable heads)
• Lower noise emission compared to many piston compressors

Powerful & efficient

• New: up to +11% flow vs previous model while keeping low weight (as little as 0.1 kg per l/min depending on configuration)
• Compatible with variable-frequency drives for energy optimisation
• Suitable for continuous operation: 100% duty cycle available

Cost-effective & environmentally friendly

• New: approx. 6% reduction in electrical consumption in the new generation
• Savings on oil, filters and oil disposal due to oil-free operation
• Lower life-cycle costs through reduced spare part needs and extended maintenance intervals
• Motors available up to IE3 for improved energy efficiency

Applications

• Commercial vehicles (trucks, buses) — compact, corrosion-resistant solution for electric and conventional fleets
• Rail vehicles — suitable for main and auxiliary air supply, retrofit and modular air stations
• Industrial systems — compact integration where oil-free compressed air is required

Configuration options

• Multiple voltage and frequency configurations (230 V, 400 V, 480 V; 50/60 Hz)
• Accessories and market-specific configurations available
• Planned: large E-Bull industrial station (from early 2025)
