High-Speed Four-Cylinder Compressor YBF4H-25.2GR


Product Overview

Blait, a global pioneer in precision industrial equipment, introduces the YBF4H-25.2GR Industrial Reciprocating Four-Cylinder Piston Compressor—a high-performance solution engineered for heavy-duty industrial applications. This compressor integrates cutting-edge technology to deliver stable airflow, high energy efficiency, and durable operation, making it a top choice for refrigeration systems, HVAC units, and industrial cooling projects. With a displacement of 73.6 m³/h and cooling capacity of 91.20 kW (using R22 at 30°C), it meets the demands of 24/7 operation while keeping power consumption as low as 13.74 kW. Its compact design (194 kg including freezing oil) also ensures easy installation in space-constrained industrial layouts.


Core Features

Four-Cylinder Balanced Operation

The compressor’s four-cylinder configuration (90×70×55 mm per cylinder) minimizes vibration and noise, creating a smoother working environment. The balanced compression structure reduces pressure fluctuations, which is critical for sensitive processes like food processing and pharmaceutical cooling. This design also extends the lifespan of downstream equipment by avoiding sudden load changes.

Superior Energy Efficiency

Equipped with a 25 HP (18.5 kW) nominal motor and optimized valve timing, the YBF4H-25.2GR cuts energy waste by 8-12% compared to conventional three-cylinder compressors. Its intelligent power adjustment adapts to real-time load demands, while the 4.5 L oil injection system ensures efficient lubrication without unnecessary energy use. This translates to lower operational costs for long-term industrial use.

Robust & Wear-Resistant Build

Made with high-strength, wear-resistant materials and reinforced steel components, the compressor withstands harsh industrial conditions (high temperature, humidity, and corrosive environments). A built-in crankcase heater prevents oil foaming during startup, reducing component wear and lowering maintenance frequency by over 50% compared to standard models.
