4A Molecular Sieve

£650.00

The 4A Molecular Sieve is a high-performance, alkali aluminosilicate adsorbent with an effective pore opening of 4 angstroms, engineered for the precise removal of water, carbon dioxide, hydrogen sulfide, and methanol from polar and non-polar liquids and gases in mission-critical industrial processes.

Competitive Advantage Spotlight
Unlike standard adsorbents that suffer from premature capacity fade or friability, our 4A sieve delivers exceptional crush strength (≥35 N per bead) and a moisture adsorption capacity of ≥21 wt% at 25°C, ensuring extended cycle life and lower regeneration energy costs. This translates directly to reduced total cost of ownership and guaranteed dew points as low as -100°C in cryogenic air separation and natural gas dehydration applications.
