Pump Exhaust Odor Control uses a specially formulated essential oil, activated and vaporized by the heat of a vacuum pump's exhaust inside a purpose-built evaporation chamber. That heat-driven evaporation multiplies the oil's fragrance output well beyond what a standard additive delivers, helping neutralize pump exhaust odor on septic and portable restroom service trucks.

This 1-gallon size keeps a single service vehicle stocked for routine refills.
