A molecular sieve is a fine-pored desiccant granulate (zeolite) that removes residual moisture from the compressed air in breathing air and compressed air compressors. It is located in the dryer cartridge of the filter stage and must be replaced regularly depending on usage.
Why molecular sieve is important in compressors
Residual moisture in breathing air is one of the criteria that good air quality monitoring systems like IDE-Airsave continuously measure. Air that is too moisture-laden can cause corrosion in cylinders and valves and compromise breathing air quality in accordance with DIN EN 12021:2014 – the molecular sieve is the stage that prevents precisely that.
When does the molecular sieve need to be replaced?
Over time, the granulate becomes saturated with moisture and loses its drying effect – the replacement cycle depends on the frequency of use, ambient humidity, and compressor runtime. IDE supplies the matching molecular sieve granules directly as a spare part from the manufacturer.
Frequently Asked Questions
What is a molecular sieve?
A molecular sieve is a porous desiccant granulate (zeolite) that binds water molecules from compressed air, thereby ensuring dry, clean breathing air.
How often does the molecular sieve need to be replaced?
That depends on the frequency of use and ambient humidity – saturated granulate loses its drying effect and should be replaced before air quality suffers.
Where can I find replacement molecular sieve for my IDE compressor?
IDE offers molecular sieve granules as well as complete dryer cartridges as spare parts directly from the manufacturer.
Usually, a preceding one works Condensate trap, which captures coarse moisture even before fine drying. Questions about the appropriate maintenance of your compressor? We are happy to advise you.
