Compare compact SCROLLVAC 3 and 3S plus with SCROLLVAC 7, 10, 15 and 18 plus dry scroll pumps.
SCROLLVAC plus provides dry scroll pumping with model-dependent single- or three-phase options. Read pumping speed at the specified frequency and distinguish standard, H and C configurations. Continuous inlet pressure, vapour load and required maintenance affect selection. A model number is not a substitute for the phase, frequency and operating limits in its instructions.
Use the correct phase/frequency performance. Check continuous inlet-pressure limits, chamber volume and standard, H or C suitability.
Both compact models deliver 3.0 / 3.5 m³/h at 50 / 60 Hz and 0.1 mbar ultimate pressure with gas ballast closed. The 3S adds a solenoid inlet isolation valve and 10-second delayed opening; the standard 3 plus suits systems with their own isolation. Select the voltage-specific 230 V build for typical UK single-phase installations and specify the mains lead separately.
Compact-model ratings and accessories do not automatically apply to the larger SCROLLVAC models. Use each model’s instructions for continuous-duty limits and gas compatibility.
Compare values with their stated gas, frequency and configuration conditions. A blank specification means it needs confirmation. Listed equipment is subject to a quotation; inclusion here does not indicate stock.
