The "IAD Series" is an inline compact membrane dryer that uses a high polymer material that is very difficult for oxygen and nitrogen to pass through, while allowing water vapor to permeate easily, in order to remove water vapor from fluids. When compressed air is passed through the inside of the hollow fiber membrane made from this material, only water vapor is discharged to the outside, resulting in dry air at the outlet side. Furthermore, by returning a portion of this dry air back to the outlet side, continuous dehumidification is achieved. 【Features】 ■ Lightweight and compact inline design ■ No drain processing required (removed moisture is exhausted as water vapor) ■ Three types available based on capacity (30R/min, 100R/min, 200R/min) ■ Can be used in explosion-proof environments as it does not require power supply ■ Compliant with RoHS regulations *For more details, please download the PDF or feel free to contact us.
