300-Liter Belt-Drive Oil Compressor, 12.5 Bar, 480 L/min, 4kW Motor

Overview

This is a workhorse compressor designed for professional shops requiring sustained, high-volume air supply. The 300-liter tank combined with a dual-piston pump delivers 480 L/min at 12.5 bar—enough to power multiple stations simultaneously without constant cycling. The belt-drive system prioritizes longevity and thermal stability over speed, making it ideal for all-day operation in busy automotive, pneumatic tool, and industrial environments.

If your operation requires flexibility across different volumes, consider pairing this unit with smaller portable compressors for remote job sites or satellite workstations.

Key Features

• Dual-Piston Pump Design: Aluminum pistons paired with cast iron cylinders deliver superior heat dissipation and extended operational life
• 300-Liter Steel Tank: Heavy-gauge construction with anti-corrosion powder coating resists rust and industrial contamination
• Belt-Drive System: Lower speed (980 RPM) reduces wear, noise, and energy waste compared to direct-drive alternatives
• Integrated Cooling: Large-fin aftercooler and oversized pulley-fan combination maintain optimal operating temperatures during continuous use
• Pressure Control: On-board pressure reducer with manometer gauge and universal quick coupler—setup-ready for immediate deployment
• Safety Engineering: Protective steel mesh guards around all moving parts (belt, pulley, cylinders); thermal motor protection prevents overload shutdown
• Full Instrumentation: Precision inlet pressure gauge and oil-level sight glass enable quick diagnostics and preventive maintenance
• Mobility: Two large 8-inch wheels plus two swivel casters with braking ensure stable positioning and easy repositioning

Business Advantages for Resellers

• High Utilization Rate: The 480 L/min output at 12.5 bar supports multiple concurrent pneumatic tools—multiplying billable air-powered work per shift
• Proven Longevity: Dual-piston, belt-drive architecture minimizes unplanned downtime, making this a preferred recommendation for shops seeking reliability over cost-cutting
• Margin-Friendly Positioning: Positioned between entry-level smaller 100L units and industrial 500L systems, this size captures the mid-market segment where most profitable service contracts live
• Low Maintenance Footprint: Integrated controls, large service access, and standard 380V three-phase power simplify installation and reduce training requirements for your customer base
• Resale Appeal: Used units maintain strong secondary-market value due to industrial-standard construction and proven track record
