Choosing the ECODRY 35 plus Dry Multistage Roots Vacuum Pump
The ECODRY 35 plus provides dry roughing and backing for clean laboratory and analytical vacuum systems. Its 35 m³/h maximum pumping speed and oil-free pumping chamber suit applications where oil carryover into the process is undesirable. The enclosed, air-cooled unit combines the pumping mechanism and controller in a compact floor or equipment-frame installation.
Choose the 35 plus when more pumping capacity is needed within the same stated enclosure dimensions as the 25 plus. Confirm the gas load at working pressure; the peak speed alone does not determine chamber pump-down time.

Maximum speed is measured at standard ambient conditions. Higher temperature, different ambient pressure and sustained high load can reduce speed. Typical ultimate pressure describes the pump, not a guaranteed pressure in the connected chamber.
Gas compatibility and controls
The manual identifies air, nitrogen, krypton, argon and helium as intended residual gases. Water vapour requires gas ballast and conditions that prevent condensation. This standard pump is not designed for flammable, corrosive, toxic or other hazardous gases; provide the complete process gas information when selecting it.
Local operation and remote serial or digital/analogue control are available. Gauge, valve and communications connections do not mean that gauges, valves or cables are included. Specify the control arrangement and matching accessories with the enquiry.
UK power and installation
For a UK 230 V single-phase installation, select the appropriate 200–240 V setting and verify the nameplate and supply protection. The manufacturer lists the 2 m BS1363-to-IEC C19 mains cable 161810UK as an accessory required for operation; include it in the quotation. Confirm voltage selection before connection.
Keep the inlet connection short and adequately sized, route the exhaust appropriately and allow airflow and service access. The dry pumping chamber is oil-free; the sealed bearing and gearbox lubrication still forms part of the pump design.
