KEY FEATURES AND BENEFITS 
WET PUMPING 
Key benefits of Edwards RV12 vacuum pump for “wet” applications:
-Highest vapor pumping capacity of any rotary vane pump
-Unique mode selector switch means pump maintains lubrication at high flow
-Highest gas ballast flow of any rotary vane pump giving 220g/hr (290g/hr on RV12) water vapor handling capacity
-Optional oil return kit to ensure the oil stays in the pump at high flow

For applications where the solvents/vapors are incompatible with fluoroelastomer (FKM) seals, a nitrile (Buna-N) conversion kit is available. Additionally PFPE prepared pumps may be ordered if pumping large quantities of oxidants.

DUSTY 
Key benefits of Edwards RV12 vacuum pump for “dusty” applications
-Best in class anti-suck back protection to prevent dust getting back into the process.Controlled opening by oil pressure to eliminate pressure surge.Rapid closing within 0.4 seconds of pump stopping due to dump valve.
-Large diameter oil passages (3-5mm) to avoid cloggingSome competitor pumps have oil passages of less than 1mm diameter.

Designed using experience of PVD and CVD applications from the semiconductor industry, Edwards range of RV pumps are ideal for dusty applications.

CLEAN/DRY
Key benefits of Edwards RV12 vacuum pump for clean/dry applications
-Unique mode selector switch means pump maintains lubrication at high flow
-Optional oil return kit to ensure the oil stays in the pump at high flow
-Best in class anti-suck back protection to prevent oil mist getting back into the process
-Controlled opening by oil pressure to eliminate pressure surge
-Rapid closing within 0.4 seconds of pump stopping due to dump valve.

The patented mode selector means that the pump is equally happy in either high vacuum applications or high throughput applications. For the latter an optional oil return kit can be fitted that allows the pump to operate continuously at high throughput without losing all its oil down the exhaust line.

OXIDANTS
Key benefits of Edwards RV12 vacuum pump for pumping oxidants:
-Highest gas ballast of any rotary vane pump.Allows dilution of pumped gases to minimize oxidation of the oil
-PFPE variants available.Ideal for pumping oxygen and halogenated compound.

The high gas ballast of the RV pumps allows higher flows of oxygen whilst maintaining dilution to below the lower explosive limit. When combined with the optional oil return kit to prevent the gas ballast from blowing all the oil into the exhaust and a PFPE prepared pump to avoid oxidation of the oil, the RV pump makes a solid pump for oxygen. Equally these same features make the RV pumps ideal for pumping other oxidants such as halogens and halogenated compounds. For these compounds fire/explosion is not an issue, but a gas ballast is still useful for dilution to protect the oil and bearings. PFPE should be used to prolong oil life.

The Edwards PD3 plate degasser is suitable for degassing photographic films and plates, prior to their use in electron microscopes. This gives the advantages of reduced pump down times and less contamination to the microscope column. This product is supplied as a chamber only. NO pump is supplied.

Mist filters capture oil mist from the outlet of pumps, which would otherwise be ejected into the atmosphere. This may happen when you use gas ballast or when you pump high gas throughputs. You can also return oil trapped in the mist filter back to the pump, although you must ensure that the process gases will not contaminate the pump or pump oil. The EMF10 mist filter is suitable for use with RV3, RV5 and RV8 pumps. They are very efficient at 99.999% DOP test and are also azide proof. The white bottom half of the body is semi-transparent, allowing the oil level to be monitored. The EMF filters have a unique odor element which neutralizes the smell of oil mist.Supplied with NW25 clamp, centering ring and O ring, NW25 to 3/4 inch BSP adaptor.

The FL20K foreline trap has been developed for use in clean pumping systems, to prevent the back-migration of rotary pump oil mist into the system.The FL20K is most useful with two-stage rotary pumps, operating below 1 mbar. To maximize sorbent life, install the FL20K near the vacuum system. In common with other types of sorbent, activated alumina absorbs water. This does not affect the oil vapor trapping properties but may tend to prolong the roughing time on successive pump downs. To minimize vapor absorption, we recommend you fit a valved by-pass line.The trap body is made of aluminum and is fitted with a removable basket containing the sorbent.
