AF Filter

The filter is also known by other names (air source filtration, air purification, etc.). Main use: purification of high-purity harmful gases. Mainly applied in polymers, organic synthesis, physical chemistry, elemental analysis, fibers, semiconductors, inorganic substances, metallurgy, environmental analysis, food analysis, gas chromatography, and other fields.

How to use:

The air filter combination triplet unit has three independent air channels; together with the gas valve it can adjust flow, deeply purify harmful gases, and remove excess moisture. Fillings: filled with color-changing silica gel and molecular sieve (a filler that removes hydrocarbons); can be filled with activated carbon (a filler that removes CO2); can be filled with caustic soda, asbestos, etc. The three paths in series achieve 3-stage deep purification.

How to use:

The device is easy to install, disassemble, and operates smoothly. During use, only the air filter regulator needs to be replaced: simply unscrew the fixing screws to lift the entire cleaning pipe, then rotate it from top to bottom.

When using the single-column gas chromatography method, the input and output markings should be determined. If the series mode is adopted, a straight pipeline should be set for each of the first-stage gas, second-stage gas, second-stage gas, third-stage gas inlet, and third-stage gas inlet; after the three-stage open/close valves are set, each valve can operate normally, and only the first and third valves need to be switched.

This product has a pressure resistance of 0.6 MPa and three gas switch valves for convenient gas switching.
