Features
PSA (Pressure Swing Adsorption) circle consists of adsorption, pressure equalization, desorption and pressure equalization four steps. Two adsorption towers are adopted to ensure continuous gas supply. Carbon molecular sieve has obvious adsorption differences to oxygen and nitrogen. There are many tiny holes inside the carbon molecular sieve. Under certain pressure, the tiny holes have different adsorption capacity to oxygen and nitrogen. When air pressure increases, carbon molecular sieve adsorbs oxygen and produces nitrogen, when air pressure drops to normal condition; carbon molecular sieve desorbs oxygen and regenerates itself. Two towers are generally provided, when one absorbs oxygen and produces nitrogen, the other desorbs oxygen and makes regeneration. This alternate process constantly produces nitrogen. This device adopts unequal pressure equalization process to increase nitrogen recovery rate and nitrogen production rate of molecular sieve, which saves energy greatly.
Application of high-purity nitrogen:
Nitrogen is widely used in various industries. It is used in nitrogen protection, pneumatic transmission for synthetic drug, pure nitrogen insulation in bioengineering and nitrogen-back-filling embedment in preparation production. Nitrogen is also used as protective gas in electronic industry and glass industry and serves as product material in chemical industry.

Shanghai Broatek is a high-tech filter manufacturer specializes in high-performance filtration products. Our product range from filter elements to post-treatment equipment for screw air compressor. We focus on continuously developing high efficiency and cost-saving products for OEMs, wholesaler and end users throughout the world.
Screw air compressor filters
With full range of replacement/retrofit filters for screw air compressor (over 10, 000 part No. ), our filter element (air filter, oil filter, air oil separators) are installed on many brand screw air compressors, most including Ingersoll-Rand, Atlas Copco, Sullair, Compair, Kaeser, Gardner Denver, BOGE, Hitachi, Kobelco, Mitsui-Seiki and Fusheng etc.
Post-treatment equipment for air compressor
Our basic product includes pipeline filtration, oil remover, desiccant compressed air dryer, refrigerated compressed air dryer, PSA nitrogen generator and self-clean air filter. All these products are made to help decreasing the damages of industrial equipment. As the compressed air contains water vapor and dust, it's a big threaten to keep machine running. Without effective control of these air during the regularly working, plug valves worn, pipeline corrupted, equipment damaged by air leakage, sometimes even caused production stagnation. Broatek is aiming at solving these problems and help our client to saving cost on maintenance.
We value sustainable relationships with our employees, customers and partners based upon honest dealings, mutual satisfaction and respect.
