The KRSB-10A is a reliable fixed speed rotary screw compressor engineered for small workshops and light industrial environments. With its belt-driven design and proven reliability, it delivers consistent compressed air at an accessible price point.

Compact & Efficient Design

Despite its modest footprint, the KRSB-10A packs a high-efficiency IE3 motor that minimizes energy consumption during continuous operation. The belt-drive system allows easy speed ratio adjustment and simplifies routine maintenance — belt replacement takes under 30 minutes with no special tools required.

Key Advantages

• Low initial investment ideal for startups and small facilities
• IE3 premium efficiency motor reduces operating costs
• Intuitive controller with real-time pressure and temperature display
• Integrated oil separator ensures clean compressed air output
• Side-panel access for quick filter and oil changes

Performance Under Real Conditions

Tested across diverse workshop environments, the KRSB-10A maintains stable output pressure even during extended duty cycles. Its oversized cooling fan prevents thermal shutdown in ambient temperatures up to 45 °C, making it suitable for poorly ventilated compressor rooms.
