Introduction
The document introduces the NDL Series of air dryers by F-DGS, designed to provide ultra-high purity, desiccant air drying solutions. These dryers are engineered for continuous operation, ensuring clean and dry compressed air, which is crucial for various industrial applications.

Need for Clean, Dry Air
Compressed air is a vital energy source in industries, but it often contains water vapor that can condense and cause damage to equipment. This moisture can also promote microorganism growth, posing hygiene risks, especially when in contact with humans, animals, food, or medical equipment.

Operational Mechanism
The F-DGS dryer operates on the pressure swing adsorption principle, using two columns with hygroscopic desiccant beds. The system includes filtration stages to remove bulk liquids and particles, ensuring continuous dry air supply through a PLC-controlled process.

Models and Specifications
The document lists various models (NDL-010 to NDL-050) with details on outlet flow rates, air loss for regeneration, connection sizes, dimensions, and weights. It also specifies operational parameters like working pressures, electrical supply, and temperature limits.

Recommendations
For air sources from oil-lubricated compressors, the installation of a 0.01 micron coalescing filter and an activated carbon filter is recommended to reduce hydrocarbons.
