Electric thermal dry fog vs pulse-jet. T-Series is now Pro-500.

Propane pulse-jet foggers (the class that includes Dramm PulsFOG / Autofog and older T-Series hardware) heat fuel to drive a wet aerosol. NeutraFog Pro-500 is electric thermal dry fog: about 1-micron droplets, remote start, typically under a minute in a sealed room.

What changed from T-250 and T-500

T-250 and T-500 are retired names. The current replacement is Pro-500: up to 105,000 cubic feet in about 30 seconds. Do not buy leftover T-Series listings as current spec.

  • Fuel: propane / combustion vs wall power
  • Droplet: wet aerosol vs ~1-micron dry fog
  • Operator: often in-room vs remote
