Edwards RV8 6.9 CFM Dual-Stage Vacuum Pump Edwards RV pumps have become the industry standard for scientific primary pumping applications. RV pumps are uniquely capable of delivering high or low throughputs with high ultimate vacuum. This, combined with ultra-low noise levels, makes them ideal for a wide range of applications including GCMS and other small bench top type applications.All pumps are approved to UL standards by an external test house. Edwards has a global network, providing world-wide support for product applications and service.Supplied with: 1 litre of Ultragrade 19 oil, inlet filter and O-ring. Fomblin must be purchased separately for PFPE RV pumps. Technology All our RV pumps are significantly quieter noise levels of 48 dBA 50Hz are typically half the noise of a conventional pump and have been achieved by extensive work on the drive train and motor. The pumps have the unique ability to deliver excellent ultimate vacuum in both high vacuum and high throughput modes with or without gas ballast. This gives the user an unrivalled opportunity to select the optimum pumping performance without compromising the application. In its high vacuum mode, the RV pump is ideal for analytical instruments, electron microscopes, physics research, backing turbo pumps, TV tube pumping and leak detection applications. Configure the same pump in the high throughput mode, and it becomes suitable for mass spectrometer inlet systems, distillation, laboratory furnaces, backing vapor pumps, solvent concentration, freeze drying and other drying applications. The simple to use mode selector and accessible, three-position gas ballast control allow the pump to be reconfigured at any time, even when the pump is running.   Applications Analytical instruments Centrifuges, ultra-high speed Coating Degassing/curing - oil, epoxy resin Distillation/extraction/filtration Freeze drying Furnaces Gas bottle filling/emptying Gel drying Glove boxes, ovens Laboratory bench top vacuum Leak detectors, Helium Load locks and transfer chambers Refrigeration manufacture Research and development Rotary, centirfugal evaporators Scanning electron microscopes - SEM SEM/FIB (ion beam repair) Solvent recovery Surface science instruments Turbomolecuar backing pumps Specifications    Model  RV8  Vacuum pump type  Dual stage rotary vane  Power  110V 50/60Hz 1-PH 5A or 220V 50/60Hz 1-PH 2.1A  Power connection  US standard 3-prong plug (NEMA 5-15P)  Motor power at 50Hz  450 watts  Motor power at 60Hz  550 watts  Peak pumping speed  6.9 CFM at 60Hz  Ultimate vacuum without gas ballast  1.5 micron/millitorr  Ultimate vacuum with gas ballast  60 micron/millitorr  Unit dimensions (WxDxH)   18.5 x 6.2 x 8.9"  Shipping dimensions (WxDxH)  31 x 11.5 x 19"  Max water vapor inlet pressure  28.5 torr (38 mbar)  Max allowed pressure at outlet  0.2 bar gauge/2.8 psig  Operating temperature range  54°F to 104°F (12°C to 40°C)  Oil capacity  Minimum 0.48 quart (0.45 L), maximum 0.8 quart (0.75 L)  Oil type  Ultragrade 19  Nominal rotation speed at 50/60Hz  1500/1800 rpm  Noise level  48 dB(A)  Inlet connection  NW25/KF25  Outlet connection  NW25/KF25  Unit weight  57 Lbs  Shipping weight  70 Lbs  Users manual  Click here to download  Certification  CE, UL
