Unique & Safer Smoke Blotter® 2-Stage System

The Phantom Switch™ is a Two-Stage Diesel Emission Control System designed to regulate emissions based on proximity, or "Smog Free Zones."

Smog Free Zones are established by use of RF (Radio Frequency) Transponders strategically placed in likely presence of humans where emissions are exhausted into the air such as school bus zones, loading docks, fire departments and public buildings.

Stage-2

Within proximity of RF Transponders, diesel exhaust is diverted downstream of the muffler into the filter; effectively reducing emissions by 99% (EPA Level 3).

With the Smoke Blotter 2-Stage System:

  • There is no pre-set time limit for protection
  • Exhaust passes through Muffler first, then to Filter or to Atmosphere
  • Muffler acts as both Silencer and Spark Arrester
  • Muffler can be a Diesel Oxidized Catalytic type
  • Filter located downstream of muffler is final exhaust trap and does not effect engines Warranty

Stage-1

In normal operation, outside range of RF Transponder, diesel exhaust passes through a muffler, which when an oxidized or catalytic type, effectively reduces emissions by 25% (EPA Level 1).

Smoke Blotter® Patented Emissions Control

  • Every other DPF System is designed to trigger on engine events: Pressure, Temperature, or Time
  • Engine events don’t relate to presence of humans
  • Time Lapse is inadequate protection
  • Smoke Blotter® Phantom Switch senses Proximity activated by RF Transponder in Smog Free Zones
  • Smoke Blotter® protects people not property
