Elmo Rietschle V-Series dry (oil-free) rotary vane vacuum pumps, compressors, and combined pressure-vacuum pumps. Three size groups: compact VTE/DTE (3–10 m³/h) for OEM applications; medium VTN/DTN/KTN (16–50 m³/h) with enhanced cooling and relief valves; large VTR/DTR/KTR (55–159 m³/h) with thermal chamber separation and one-side servicing. Oil-free operation reduces life-cycle cost and eliminates process contamination.
