Third-grade filter for refuge chambers

Three-stage Filter for Refuge Chamber Chamber Compressed Air Three-stage Filtration Device

1 Domestic brand filter elements are all produced by our company as replacements for original brand filter elements. The filtration material uses products from the German company HV, with the registered trademark "Jiajie". Other brands mentioned by our company hold no brand significance and are only used for product model reference and customer selection comparison. Imported filter elements and filters are originally imported with anti-counterfeiting labels. Our company has long been engaged in OEM production of various styles of compressed air precision filter elements for major domestic enterprises.

Company supplies: For refuge chamber use three-stage filter air purification system, chamber compressed air three-stage filtration device, refuge chamber three-stage filter, three-stage filter. This system utilizes the pre-buried compressed air pipeline in the chamber as the air source. After passing through the valve, it first enters the three-stage filtration for water, dust, and oil set in the transition chamber, then passes through the pre-installed pressure reducer and pipeline to the gas output end. Using C, T, A three-stage filtration, it removes impurities and oil droplets as small as 0.01μm, making the filtered air meet medical gas standards, which is then delivered to the breathing masks for each person, providing fresher and more comfortable air for people in the refuge.

Our company specializes in dedicated configurations for compressed air oxygen supply systems for refuge chambers. The entire compressed air system consists of compressed air oxygen supply device, three-stage filter, pressure reducer, silencer, flow meter, control valve, joints, elbows, etc., all of which our company will provide. Feel free to call for inquiries at any time.
Main technical parameters
Per capita air supply≥0.3m³/min;
Oxygen concentration in the refuge18.5～22.0%;
Pressure reducer inlet pressure≥0.8MPa, outlet pressure0～0.6MPa (adjustable), output flow not less than36m³/min;
1. Control continuous noise not exceeding70dB(A), tested with a sound level meter at a point 1m from the noise source,
2. Three-stage filter
Using T/A/H three-stage precision filtration, removing impurities and oil droplets as small as0.01μm, making the filtered air meet medical gas standards.
Inlet pressure:0.7~0.8Mpa, outlet pressure:0.2~0.3Mpa.
Using a large flow pressure regulating valve to reduce compressed air pressure, achieving0.3m³/person per minute.
Using a large flow air filter, achieving0.3m³/person per minute
(II) Compressed Oxygen Supply System
This system can achieve manual or automatic control of oxygen supply for the refuge chamber. When the explosion-proof solenoid valve is opened, it starts to fill the pipeline with oxygen to meet the oxygen supply requirements.
Main functions
It can still effectively supply oxygen when the underground pipeline of the ground compressed air system is severely damaged. It adjusts and controls the supply of compressed oxygen according to actual conditions to meet normal human breathing needs for survival.
Working principle:
This device uses medically compressed oxygen stored in steel cylinders, outputting a specified amount of oxygen to避难 personnel through the oxygen supply control device. The cylinders placed in the survival chamber are connected in parallel via high-pressure pipelines, then pass through an explosion-proof solenoid valve, pressure gauge, pressure reducer, and gas flow meter, delivering the medically compressed oxygen from the cylinders to the breathing masks of each person.
Oxygen supply: 0.5 liters/minute/person
Oxygen content: Oxygen concentration maintained between18.5%～23%
Life-saving cabin compressed air filtration system
