IDFB series refrigerated air dryers are cUL listed for use in North America.  These 60 Hz models have rated flows up to 459 SCFM (780 m³/hr [ANR]).

IDF series refrigerated air dryers are capable of operation on 50 or 60 Hz power for use throughout the world where specific certifications aren't required.  This series includes SMC's largest units with rated flows up to 2,295 SCFM (65 m³/min [ANR]).

• Standard inlet temperature air
• Stainless steel heat exchangers designed for long life and low pressure drops
• Compact and quiet construction
• Montreal Protocol compliant refrigerants
• Energy efficient designs

IDFA series refrigerated air dryers are CE marked for use in Europe and other regions that require this mark.  These 50 Hz models have rated flows up to 883 SCFM (1500 m³/hr [ANR]).

Series IDU provides a stable supply of dry air even under high demand conditions with an inlet air temperature up to 176°F. The IDU's stainless steel heat exchanger improves corrosion resistance. Each unit is also equipped with an evaporation thermometer as a standard feature.

• Designed for use with compressors or systems that do not include an after-cooler
• Integral after-cooler permits max. inlet air temperature: 176°F/80°C
• Well suited for use with reciprocating compressors
• Available in flow ratings up to 441 scfm / 12.5m³/min (ANR) (@50°F/10°C PDP)
• Connections: R threads are standard; NPT adapters available

SMC's series IDH compact air dryer offers stable, compressed air temperature control with its integrated heater, regulator, dryer, and filter. The IDH air dryer delivers a constant volume of compressed air at the correct temperature, dew point, pressure and cleanliness, regardless of external conditions or seasonal climatic conditions. Due to it's compact size, and the ventilation holes being on the front and top, the IDH can be installed close to a wall or panel.

• For air bearing, other applications where constant controlled temperature dry air is required
• With standard integral regulator, optional filtration
• IDH: 50/60Hz operation; IDHA: 50Hz operating CE marked
• Montreal Protocol compliant refrigerants
• Energy efficient designs

Optional accessories include: a separately installed power transformer (supplies other than standard power and voltage); dedicated base (integrates a separately installed power transformer and the air dryer); dust-protecting filter set (prevents a decline in the performance of an air dryer); bypass piping set (connecting this set to the air dryer allows a substantial reduction in installation time); foundations bolt set (fixes the air dryer to the foundations); and a piping adapter (converts the thread type of and IN/OUT fitting for an air dryer).
