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.
Benefits of the mist filter include:
• Protection from oil mist emissions as required by COSHH and health and safety regulations.
• Use of optional oil return kits results in reduced oil level maintenance and savings in pump oil.
• If the oil element becomes blocked, an integral pressure relief valve opens.

EMF filters The EMF3, EMF10 and EMF20 mist filters are suitable for all small rotary vane pumps up to E2M18. 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.
MF30 filter The MF30 is suitable for E2M28 pumps. It is very efficient at 99.85% DOP test. You can monitor the oil level through the sight-glass provided.
Oil return kits These conserve the pump oil, by returning the oil trapped in the mist filter to the pump. The gas ballast oil return kit, for example, allows extended operation of the pump with gas ballast. |

INLET LIQUID CATCHPOTS
These catchpots minimize the entry of condensable vapors into the pump.
Benefits of the catchpots include:
• Capture condensable vapors, which would otherwise condense in the pipelines or in the pump.
• Prevents froth or spray from the process from carrying over to the pump
• Corrosion-resistant body
• Visual indication of trapped liquid level
• Hand-tightened drain plug, for easy drainage. |
ITF20K INLET DUST FILTER
The ITF inlet dust filters prevent the entry of dust particles into the pump. The impedance of a clean filter reduces the pumping speed of a 20 m3h-1 pump by about 20% at 1 mbar and 25% at 10 mbar.
Depending on your application, you can normally clean the filter element with a vacuum cleaner or a clean air blast, and then re-use the element.
The benefits of the ITF filters include:
• Thick aluminum casting, to withstand abrasion.
• Tangential entry port, to promote centrifugal separation of dust particles.
• Filter efficiency better than 96% (tested to BS2831, dust number 2).

ITC20K INLET CHEMICAL TRAPS
The ITC series of chemical traps provides the following benefits:
• Protection against various aggressive vapors, which may attack the pump or pump oil.
• Prevent high molecular weight vapors (such as might arise in a resin treatment plant), from reaching the pump. These vapors could cause lacquering or clogging.
• The standard sorbent (activated charcoal), has relatively high trapping properties (absorbs around 25% of its own weight), even when large amounts of water vapor are being pumped.
• When filled with activated alumina on two stage pumps, backstreaming of pump oil can be controlled.
• See also ITO catchpots for design advantages of the body.

FL20K FORELINE TRAP
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 activated alumina sorbent has the following benefits:
• Exceptional trapping properties for oil mist (99.7%)
• A very long life before it is saturated
• Can be rejuvenated by baking the basket containing the sorbent for 2 hours at 250 °C -
300 °C.
|
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. |
WATER JET PUMP 0.23 m3h-1
Fits laboratory tap and ordinary water supply for simplest production of
rough vacuum for distillation, filtration, aeration etc. An integral nonreturn
valve prevents system flooding from fluctuating water pressures.

OIL BOX DRAIN KITS
Two kits are available:
• RV easy oil box drain kit. This kit includes an oil drain extension tube
for use when the oil is gravity drained.
• Fits E2M0.7, E2M1.5, RV, E1M18, E2M18, E2M28.
• ODP20, for use with the E1M18, E2M18 and E2M28 pumps. This accessory provides alternative methods for draining oil where access to the pump drain plug is difficult, or where there is no room for a receptacle under the drain outlet. The pack includes an oil drain extension tube for use when oil is gravity drained, and a pressure drain device with which the oil can be discharged at a high level.

OB20 OIL BOX PURGE ADAPTOR
This stainless steel adaptor enables a flow of dry inert gas to be introduced into the oil box to provide large scale dilution of process gases which cannot be dealt with sufficiently by the standard gas ballast facility. The adaptor replaces the oil filler plug, on the RV and E1M18/E2M18 pumps only. |

OIL CHANGE REMINDER TAG
The oil change reminder tag is a useful reminder for users to change the oil when it starts to go brown. Brown oil indicates that the oil is contaminated or degraded, and must be changed to prevent mechanical wear or failure of the pump. Tie the tag onto the pump exhaust so that it hangs over the oil box. |
