Compressed Air Drying
Removes water vapor in compatible adsorption dryers and pneumatic systems.
Industrial Adsorbent Material
4A Molecular Sieve
4A Molecular Sieve: Sodium type A zeolite, 4Å pore. Review applications, particle size, storage, samples, and quotation requirements.
Technical Specifications
pore size 4Å
composition Sodium type A zeolite
form Spheres or extrudates
common particle sizes 1.6-2.5 mm and 3-5 mm; confirm equipment requirements
regeneration temperature Process- and grade-dependent; confirm the supplier TDS
Applications
Industrial Gas Drying
Provides deep drying where the gas composition is compatible with the 4A pore opening.
Liquid Drying
May be used for suitable liquids and solvents after compatibility review.
Regenerative Drying Systems
Supports cyclic adsorption and regeneration when the equipment is designed for the selected grade.
Advantages
- General-purpose molecular sieve for industrial water removal
- Suitable for many air, gas, and liquid drying duties
- Available in particle sizes for different bed designs
- Can achieve deeper drying than general humidity-control desiccants in suitable systems
Limitations
- Feed composition must be compatible with the pore opening
- Oil, liquid water, and dust can reduce bed performance
- Changing particle size can affect pressure drop and mass transfer
Frequently Asked Questions
What is the pore size of 4A Molecular Sieve?
The nominal pore opening is 4Å. Adsorption suitability still depends on molecular dimensions, polarity, process conditions, and the selected grade.
What is the regeneration temperature?
Regeneration temperature is Process- and grade-dependent; confirm the supplier TDS. Proper regeneration restores adsorption capacity for multiple cycles.
What standards does it comply with?
ISO-9001, REACH
How should it be stored?
Store in a dry environment before use. Avoid exposure to acidic gases. Keep sealed when not in use to prevent premature moisture adsorption.
