The pure-flow air heater is designed for applications where clean air is required such as laboratories and environmental testing areas. It uniquely supplies pure air by passing air over an enclosed heated surface rather than directly over exposed resistance elements. This method assures that no foreign matter can enter the air flow.

  • Wetted parts constructed entirely of 316 stainless steel
  • Operating range of up to 15 CFM with temperatures to 800°F
  • Pressure rating: 100 PSIG
  • Compatible with air and most liquids, including potable water
  • Made in USA

Wattage calculation and heater selection

For applications with input temperatures below 120°F, you can find the required wattage quickly by plugging the flow rate (Rflow, in SCFM) and temperature rise (ΔT, in °F) into this formula:

Required kW = Rflow • ΔT3,000 • 1.2

For detailed background on selecting a heater, see the article in the box on this page.
