English Product Introduction for SG1070A-55 & LGFD-10.7/7 Screw Air Compressors

1. General Overview

This document covers two matched 55kW industrial screw air compressors for 0.7MPa working pressure:

· SG1070A-55: KOBELCO permanent magnet variable frequency (VSD) screw air compressor, energy-saving model

· LGFD-10.7/7: Fixed-speed silent enclosed twin-screw air compressor, standard industrial base model

Both units share identical core capacity: 55kW /75HP motor, free air delivery 10.7m³/min at 7bar(0.7MPa), air cooling design. They are widely matched for medium & large factories, providing

1. Core Technical Parameters

3. SG1070A-55 (KOBELCO VSD Energy-Saving Model) Key Features

3.1 Original Japan High-Efficiency Screw Air End

Adopts KOBELCO optimized asymmetrical rotor profile, ultra-precision machining to minimize internal air leakage. Low linear rotor speed cuts mechanical loss and heat generation, with design service life over 100,000 hours. Imported heavy-duty SKF bearings ensure stable low-vibration operation.

3.2 IE3 Permanent Magnet Variable Frequency Motor

Integrated rare-earth permanent magnet synchronous motor, IP55 dustproof & waterproof, F-class insulation. Compared with traditional fixed-speed machines, it saves 20%~35% electricity under fluctuating air consumption by adjusting motor speed to match real-time air demand, eliminating wasteful unloading power loss.

3.3 KOBELCO Exclusive Intelligent VFD Control System

· Precise constant pressure control, pressure fluctuation controlled within ±0.01MPa

· Built-in energy-saving logic: auto forced unloading after 30s idle to avoid useless power consumption

· Real-time monitoring of pressure, exhaust temperature, running hours, fault codes and maintenance reminders

· Multi-language interface, supports remote signal output for factory central air management

3.4 Low Noise & Compact Integrated Cabinet

Fully enclosed sound insulation structure with thick flame-retardant sound-absorbing cotton, operating noise lower than 70dB(A). All components pre-installed on one base frame, plug-and-play without complex foundation construction, saving workshop floor space.

4. LGFD-10.7/7 Fixed Speed Silent Screw Compressor Advantages

4.1 High-Reliability Twin Screw Air End

5:6 asymmetric rotor profile design, large compression chamber to boost volumetric efficiency. Elastic coupling direct drive removes belt transmission loss, power transfer efficiency reaches 98%. Suitable for factories with stable, constant air consumption demandMade-in-Ch....

4.2 Silent Enclosed Cabinet Design

Complete closed sound insulation housing with internal sound absorption cotton and noise isolation partition, effectively block mechanical and airflow noise. Side shutter heat dissipation structure balances cooling performance and noise reduction, meeting strict workshop environmental standards.

4.3 Three-Stage High Precision Oil-Air Separation System

Grade 1 air filter, grade 2 oil filter, grade 3 high-efficiency oil separator core, residual oil content in compressed air below 3ppm. Protect downstream dryers, filters, pneumatic valves and precision spray equipment from oil pollution, extending service life of post-processing equipment.

4.4 Heavy-Duty Air Cooling System

Large-area aluminum plate-fin aftercooler + high-flow axial cooling fan, stable operation under ambient temperature up to 45°C. Rapidly reduce exhaust air temperature and condensed water, avoid pipeline corrosion and water mixing in compressed air.

4.5 Low Maintenance & Universal Consumables

Standard maintenance cycle: 2000hrs for air filter, oil filter and compressor oil; 8000hrs for separator element. Standardized spare parts globally available, wide maintenance door reserved for fast inspection and component replacement, cutting downtime cost.
