If you’re compressing air, you’ll likely need an air dryer! Air dryers are essential components in compressed air systems, designed to remove excess moisture from the air. They can be integrated into the compressor or used as standalone units. The two main types of air dryers are:
Refrigerated Dryer. This type of dryer cools the compressed air, causing moisture to condense and separate from the air. Refrigerant dryers are the most common option for compressed air systems. We offer the SAD series, designed to suit most low-pressure compressor models (≤1.3 MPa), and the SHAD series, tailored for more demanding high-pressure models (≤4.0 MPa), ensuring efficient moisture control in various applications.
Desiccant Dryer. Desiccant air dryers remove moisture from compressed air by using desiccant materials that adsorb water vapor. These dryers are ideal for industries requiring exceptionally dry, clean air, such as pharmaceuticals and chemicals, ensuring high-quality air for sensitive applications. They can be further divided into two types, heatless and heated desiccant dryers. Heatless type (SAD-WXF Series) use compressed air to regenerate desiccant, while heated type (SAD-MXF Series) use external heat. Both types provide ultra-dry air for critical applications, like pharmaceuticals.

Turnkey Solutions for Your Industrial Production
Gairs compressors are supported by a comprehensive range of dryers and accessories. Together, our products create a complete, integrated solution for all your compressed air needs. Keep reading to discover more about how we can optimize your system.
-
Gairs’ OGWBD series were specifically developed to meet the demands of users in industries such as glass bottling, who previously relied on pressure-reducing valves on 7-10 bar machines to achieve low-pressure effects.
-
PET Bottling ProductionGairs’ OGWBE series are capable of achieving exhaust pressures up to 40 bar during plastic bottling. Compared with traditional piston compressors, the biggest advantage of OGWBE series is energy saving and low maintenance cost.
-
By avoiding oil contamination, oil-free compressors help in reducing defects and ensuring the high quality and reliability of semiconductor products, which makes them a preferred choice in this high-tech industry.
-
PharmaceuticalOil-free compressors ensure that the air used in pharmaceutical processes, such as filling, packaging, and other operations, does not carry oil that could lead to contamination or affect the operation of sensitive equipment.
-
FermentationLow pressure (3 to 5 bar) is needed during aeration and mixing process which involves introducing air into the fermentation vessel to supply oxygen to microorganisms or to mix the contents. OGWBD sereis would be a great choice for this application.
Air Compressor System Installation Guide
Since water-injected oil-free single screw compressors contain no oil, installing the C and T series air filters is typically sufficient. However, for more demanding applications, such as in the pharmaceutical and chemical industries, additional A series filters or sterilizing filters are required to meet stringent compressed air quality standards.
