MCH6 EVOLUTION
The document outlines the evolution and technical specifications of the MCH 6 compressor by Coltri Compressors, highlighting its development over the years and its application in various fields such as firefighting, diving, and industrial use.
History and Evolution
The MCH 6 compressor has undergone significant evolution since its inception in the 1970s. The focus has been on continuous improvement in design and manufacturing, leading to the current models like the Icon and Mini Compact compressors.
Technical Features
The MCH 6 Evolution features a splash lubrication system with a conrod pin immersed in oil, a precisely crafted aluminum crankcase, and stainless steel components. Key strengths include forged aluminum connection rods, a forged steel crankshaft with hardened rings, and multiple safety valves across different stages.
Construction Details
The compressor is constructed using a combination of materials: 72% aluminum, 16% steel, 6% stainless steel, 4% plastics, and 2% brass. The design includes a four-stage cylinder system with specific bore sizes and a clockwise rotation direction.
Performance Specifications
The MCH 6 has a charging rate of 100 l/min and operates at a speed of 2,250 RPM. It features a four-stage compression system with intermediate pressures ranging from 4.5 bar to 75 bar. The maximum intake pressure is 1.3 bara.
Purification and Safety Systems
The compressor includes an Eco-Filter purification system with a disposable cartridge, capable of processing air at pressures up to 360 bar. The system ensures compliance with air quality standards, maintaining low levels of contaminants like CO and CO2.
Applications
The MCH 6 is versatile, serving various sectors including firefighting, military, racing, and industrial applications. It is designed to provide clean breathing air, adhering to stringent safety and quality standards.
