Formula used

Recovery time is estimated as t = (V / Q) x ln(P1 / P2), where volume and flow define the base exchange time and the pressure ratio defines how far the recovery process must go. SF6 mass is estimated from the ideal gas relation m = PVM / RT.

Calculation results are for reference only. Real recovery and evacuation time depends on service cart capacity, pump condition, hose type and length, connector bore, gas temperature, filter condition, compartment geometry, moisture release, and site operating conditions. Please confirm final specifications before maintenance or quotation decisions.
