Overview

The core function of the MCH D300 breathing air high-pressure compressor is to generate high-quality breathing compressed air that meets and exceeds the EN12021 standard. Through the equipped two inflation hoses, it can quickly inflate two gas cylinders at the same time, significantly improving inflation efficiency. Its main usage scenarios include firefighting and rescue, industrial safety protection, diving operations, and other fields that require safe breathing air sources for personal protective equipment gas cylinders. It can provide continuous and reliable breathing air protection for relevant personnel when working in hazardous environments such as oxygen deficiency, toxicity, or air pollution, ensuring job safety and efficiency.

MCH D300 breathing air high-pressure compressorThe core function of the device is to generate high-quality compressed air for breathing that meets and exceeds the EN12021 standard. The two equipped inflation hoses can quickly inflate two gas cylinders at the same time, significantly improving inflation efficiency. Its main usage scenarios include firefighting and rescue, industrial safety protection, diving operations, and other fields that require safe breathing air sources for personal protective equipment gas cylinders. It can provide continuous and reliable breathing air protection for relevant personnel when working in hazardous environments such as oxygen deficiency, toxicity, or air pollution, ensuring job safety and efficiency.

IIProduct composition and functions:

MCH D300 breathing air high-pressure compressorWithDThe series piston compressor is the main engine and adopts a three-stage compression mechanism, with a maximum working pressure of up to33MPa， Strong performance. The left side of the host is equipped with a three-phase motor, and the fan and pulley are both equipped with protective covers, which have the functions of air guidance, heat dissipation, and safety protection, effectively avoiding the risk of accidental contact during operation. Air filters are installed at the inlet and outlet to purify the inhaled air and ensure the quality of the produced breathing air from the source. The machine is equipped with a built-in condensate drain valve, which can reduce the residual condensate inside the equipment through timed drainage, thereby improving the durability of the machine; The final safety valve serves as an overpressure protection device, which automatically starts to release pressure when the system pressure rises abnormally, minimizing safety hazards caused by operator misoperation or equipment failure. In addition, the machine is equipped with two inflation hoses as standard, which support simultaneous inflation of two gas bottles, greatly reducing inflation time in practical use and optimizing the user experience of the equipment.
