Our dryers can be used with fractional horsepower compressors as well as the larger compressors required for environmental remediation system applications.

  • Very dry outlet air to -100°F (-73°C) dew point
  • Flow capacities of .1 SCFM (.0028 m3/min) to 50 SCFM (1.415 m3/min)
  • Compact and lightweight design requires less space
  • Solid-state timer with built-in memory for accurate cycling and energy savings
  • Install at point-of-use or use with fractional horsepower air compressors
  • Precision orifices to control purge
  • Non-plugging and non-corroding purge mufflers
  • Standard NEMA 4 Electricals
  • Designed for the 21st Century and based on field-proven Pressure Swing Adsorption (PSA) technology.
