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.

These catchpots minimize the entry of condensable vapors into the pump. Sorbent charge not supplied. Supplied with NW25 clamp, centering ring and ring.Inlet traps, dust filters and catchpots body is made of aluminum material with a detachable metal top cover.The inlet-port is at a tangent to the body to achieve a degree of centrifugal separation of solid and liquid particles.All inlet traps, catchpots and filters of the same size and dimensions have the same body. The traps and filters have containers and filter elements which fit inside the body.For the protection of pumping system they should be installed as close to the vacuum pumping system as is possible.The ITC Inlet Chemical Trap prevents the pump against aggressive or heavy, lacquer-forming vapours which may harm the pump or contaminate the pump oil.

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.

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 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. Supplied with NW25 elbow, NW25 clamp, NW25 to 3/4 inch BSP adapter and NW25 Co-Seal.

These catchpots minimize the entry of condensable vapors into the pump. Supplied with NW25 clamp, centering ring and O ring.

The inlet dust filter has two functions. It can be connected inline between the pump inlet and the chamber outlet connection to preclude dust from migrating into the system. Alternatively, it can be connected inline between the pump exhaust and the exhaust extraction system. The filter is supplied ready to use with a 5 micron element.

An ACX air-cooler is used to cool an EXT pump when a suitable cooling-water supply is not available or for an EXT pump in a mobile pumping system. The ACX air-cooler is an enclosed electrical fan and fixing bracket assembly which is easily fitted to bolt holes in the base of the pump.The ACX air-cooler has a 24 V d.c. motor which can be powered and controlled from a rear panel socket on the EXC Controller. It is supplied with 3 m of electrical cable.
