Fusheng Screw Compressor

Updated: 2026-07-15

Overview

The Fusheng Screw Compressor is a rotary-type air compressor leveraging twin helical screws (rotors) to deliver continuous, pulsation-free compressed air. A flagship product of Fusheng Group, a Taiwanese industrial manufacturer established in 1953, it dominates mid-to-large-scale applications due to its superior efficiency (up to 15% energy savings versus piston models) and 30,000–60,000-hour lifespan. Common variants include oil-injected (for heavy industry) and oil-free (for food/pharma) models, with outputs ranging from 10 to 500 CFM. Designed for 24/7 operation, these compressors integrate smart controls like variable speed drives (VSD) to adjust output dynamically, reducing wasted energy. They comply with international standards such as ISO 1217 for performance testing and CE for safety, making them a preferred choice for global OEMs and plant operators.

Structure and Working Principle

The compressor’s core comprises a male and female rotor meshing within a sealed chamber. As the rotors counter-rotate, air is trapped in the cavities between them, progressively compressed as the space diminishes along the screw length. Oil-injected models use lubricant to seal gaps, cool the system, and reduce wear, while oil-free versions employ specialized coatings and precision tolerances. Critical subsystems include the airend (compression unit), motor (typically IE3 premium efficiency), filtration (pre- and post-compression), and control panel. Advanced models feature IoT-enabled sensors for real-time monitoring of pressure, temperature, and energy consumption via cloud platforms, enabling predictive maintenance.

Key Features

Energy Efficiency: Fusheng’s VSD models adjust motor speed to match demand, cutting idle-time energy use by up to 40%. Their airends utilize asymmetric rotor profiles (patented designs) to minimize internal leakage. Noise Reduction: Sound levels as low as 62 dB(A) are achieved through encapsulated designs and vibration-damping mounts, suitable for noise-sensitive environments like hospitals. Durability: Rotors undergo nitride hardening for wear resistance, while cast iron housings dissipate heat effectively. Optional corrosion-resistant coatings are available for humid or marine applications.

Application Areas

Manufacturing: Powers pneumatic tools, CNC machines, and assembly lines in automotive and electronics sectors. Construction: Supplies air for jackhammers, sandblasting, and painting equipment on job sites. Portable units are trailer-mounted for mobility. HVAC: Drives air curtains and control systems in large buildings. Oil-free variants are critical for medical air supplies in hospitals. Energy: Used in gas pipeline boosting and renewable energy systems like biogas compression.

Maintenance and Precautions

Routine Checks: Inspect oil levels (for oil-lubricated models) every 500 hours; replace air filters every 2,000 hours. Monitor belt tension and alignment to prevent slippage. Critical Alerts: Address high-temperature warnings immediately to prevent rotor damage. Water condensation in tanks should be drained daily to avoid corrosion. Professional Servicing: Annual overhaul by certified technicians is recommended to recalibrate sensors and replace wear parts like bearings. Use only OEM-approved lubricants to maintain warranty validity.

B2B Procurement Guide

Specification Matching: Calculate required CFM (cubic feet per minute) by summing all air tool demands plus 30% redundancy. Standard models operate at 100–150 PSI, but high-pressure versions (up to 600 PSI) are customizable. Supplier Evaluation: Verify fusheng-authorized distributors for genuine parts and after-sales support. Request performance test reports (e.g., specific power consumption in kW/100 CFM). Cost Considerations: Total cost of ownership (TCO) should factor in energy consumption (e.g., a 75 kW VSD unit saves ~$15,000 annually over fixed-speed). Leasing options are available for short-term projects.
