## Overview

HFS Molecular Sieve Zeolite 3A (8x12 mesh, 500g) is a high-performance aluminosilicate desiccant designed for industrial gas drying and purification. With a bulk density of 0.70-0.82 g/ml and water adsorption capacity of 19-20 wt%, it ensures efficient moisture removal. Its low attrition rate and high size uniformity guarantee long service life, while its low regeneration temperature optimizes energy use. Trusted by labs and industry alike, it prevents moisture-related issues like cold tower phenomena in air separation units.

## Description

[SIZE]: Mesh:8*12; Bead Size: 1.6~2.5; Bulk Density: ≥0.70~0.82 g/ml [USING PARAMETERS]: Equilibrium Water Capacity @25℃: ≥ 19.0~20.0 wt%; Equilibrium Ethylene Capacity: ≤3.0mg/g; Heat of Adsorption: BTU/lb of H2O 1800; Point Contact: N≥20~58; Variation Coefficient: 0.3; Attrition Rate: wt%≤ 0.1; Size Qualification %≥ 98; Package Moisture: wt%≤ 1.5 [HIGH PERFORMANCE]: High CO2 adsorption capacity, low regeneration temperature and long service life [COMPONENT]: Aluminosilicate [APPLICATION]: Applied in the desiccating process of industrial gas and gas purification in air separation unit; Improve the ability to absorb carbon dioxide and water so as to avoid the occurrence of cold tower phenomenon in air separation process

Review: This is the best thing you can get for drying 3D printer filament, hands down. I've used maybe 100g of it so far. Humidity has stayed near zero for about 3 months. This jar is a lifetime's worth. If you're on the edge, DO IT.
Review: A must have in any lab, great for drying solvents

## Questions & Answers

**Q: Can I use this to dehydrate ethanol?**
A: I use it for this purpose as well.  Common store purchased 151 proof grain alcohol can be very pure with this.  I do 2 absorption and separations to get anhydrous or nearly anhydrous ethanol   A plain coffee filter or filter paper removes most of the dust/cloudiness.  The rest easily settles out over a few days and the liquid can be separated from it.

**Q: What is the regeneration temperature and time for these?**
A: Molecular sieves are definitely not a single-use material. You could do that but you're "doing it wrong."

There are numerous recommendations for drying/reactivating them. Try one or more until you find one that works for you.

**Q: Would this work for oxygen concentration? (Removing N2 from O2?)**
A: Lithium zeolite and argon zeolite are the 2 most specific types for oxygen concentration.  Lithium is the most effective, but also more costly.

**Q: At what temperature do these molecular sieves regenerate?**
A: I regen at 250 to 300 1 hr with heated air the dewpiont less then 10% other people have deferential results best to keep air moving without burning if you burn the sieves that will be less effective to absorb water molecule if you live in dry climate it takes less energy humidity plays big factor you have to experiment in your area
