5A Molecular Sieve Adsorbents for O2 Generator
Activated alumina PSA adsorbent is a kind of solid material with high porosity and dispersity. It has not only good adsorption performance, but also good pressure resistance, wear resistance and heat resistance. It has a long service life and can reduce the production cost of enterprises.
Product Introduction
We always follow the innovative concept of taking the company's development of new products as the core and providing customers with superb Activated Alumina Ball For Catalyst Support, Activated Alumina Ball For Drying Agent, Activated Alumina For Hydrogen Peroxide Processing as the goal. We are confident that we can provide customers with satisfactory products and services. Our corporate mission is to satisfy customer needs and enhance corporate competitiveness with superior products and services.
Brief Introduction
Activated alumina PSA adsorbent balls produced by Avant has uniform particle size, large surface area, high mechanical strength and high moisture absorption.
This product of ours is a specially adsorbent for PSA gas separation device. PSA technology has been widely used in petroleum, chemical industry, metallurgy, environmental protection, food, electronics, aviation and other industries.
Activated alumina desiccant is not only produced for drying, but also can absorb the vapor of lubricating oil from contaminated oxygen, hydrogen, carbon dioxide, natural gas, etc.
At present, activated alumina PSA adsorbents has played an important role as a desiccant and purifier in the electronics industry, air drying of automatic instruments, fertilizer, steel, and petrochemical industries.

Pressure swing adsorption(PSA) recycle is the recycle of adsorption and regeneration. The adsorption process is that the adsorbent absorbs some components of the mixture when pressurized, and the unabsorbed components flow out through the adsorbent laminar flow. When the adsorbent is saturated with strongly adsorbed components, the adsorption tower needs to enter the regeneration process, namely desorption process.
The products produced by us can give full play to their adsorbability and good reproducibility in the adsorption process, and can be reused for many times. The effective stability and high adsorbability of the device are guaranteed, and the operating efficiency is greatly mentioned.

Our activated alumina PSA adsorbent material is selling well in the Middle East, India, Central Asia and Southeast Asia.
Regeneration life up to 5 years. Because of it's excellent adsorption capacity and recycling, it greatly saves cost and wasted time for the operation of PSA units in industrial production.
We have many years of R&D and manufacturing experience in the field of 5A Molecular Sieve Adsorbents for O2 Generator, and can improve the most cost-effective products for you. We follow latest effective washing and straightening processes that allow us to offer unmatched quality of products for our clients. We win the trust of users with a good reputation, and create value for customers and create opportunities for employees.
