View quote listThe ECODRY 40 plus is an air-cooled dry multistage Roots pump for clean-gas laboratory vacuum, analytical equipment and turbomolecular backing. Maximum air pumping speed is 40 m³/h without gas ballast, with an ultimate pressure below 0.03 mbar under the same gas-ballast condition.
Choose the 40 plus where a DN25 inlet and 40 m³/h air capacity meet the duty. For more capacity, the 65 plus increases air speed to 55 m³/h and uses a DN40 inlet.
| Specification | Details |
|---|---|
| Maximum pumping speed | 40 m³/h on air, without gas ballast; ±5% |
| Ultimate pressure | <0.03 mbar without gas ballast |
| Inlet / exhaust | DN25 ISO-KF / DN16 ISO-KF |
| Electrical supply | Single-phase 100–120 V or 200–240 V ±10%, 50/60 Hz; separate order codes |
| Rated power / current | 1200 W; 15 A low-voltage version / 10 A high-voltage version |
| Dimensions (L × W × H) | 623 × 320 × 298 mm; allow additional connection and cooling clearance |
| Mass | Approximately 43 kg, ±1 kg |
| Cooling / ambient | Air-cooled; 5–40 °C |
| Gas ballast | <0.1 mbar ultimate pressure with gas ballast; 20 mbar water-vapour tolerance |
| Water-vapour capacity with gas ballast | 300 g/h |
Pressure and speed refer to the pump, not guaranteed chamber performance. The 40/65 platform has different pressure, connection and electrical ratings from ECODRY 25/35 plus.
For a UK 230 V installation, specify the 200–240 V version. The mains cable is ordered separately: Leybold lists 161810UK, BS1363 to IEC C19, 2 m. The pump has an IEC C20 inlet; confirm circuit protection and the selected nameplate rating.
The manual lists two centring rings, two clamping rings, two blank flanges and the D-sub 9-pin bridge connector for manual operation in the supplied equipment. Interface cables, inlet screens and mounting accessories require separate selection.
The standard 40/65 plus pumps suit clean, dry, particle-free gases and water vapour within their gas-ballast limits. Give the full gas composition before selecting a pump for solvents or aggressive gases. Gas ballast improves vapour handling but raises ultimate pressure.
Local start/stop, the X1 control interface and the X104 RS485 interface support equipment integration. Specify the intended control method and cables. The dry pumping chamber has no process oil; bearings and gears use PFPE lubrication.
The manual excludes short-cycle pumping with high repetition rates. Above 2000 m installation altitude, inlet pressure should not permanently exceed 50 mbar. Allow unobstructed cooling airflow and service access.

For turbo backing, compare the TURBOVAC i / iX range. A standalone backing pump does not imply compatibility with a preconfigured TURBOLAB station.
For an ECODRY 40 plus quotation, send chamber volume, target pressure, gas and vapour composition, continuous throughput, pump-down time, cycle frequency, inlet and exhaust connections, electrical supply and quantity. Include control, filtration and installation-space requirements. Girovac will confirm the configuration, included equipment, price and delivery.
