VRX50 Vent Restrictor B58066024 (B58066024)
Fit a VRX vent-restrictor to your EXT pump if you will vent the pump when the pump speed is above 50% of full rotational speed. The vent-restrictor restricts the flow-rate of the vent gas into the EXT pump. You can also use the VRX to replace the standard restrictor supplied with the PRX10 purge restrictor to obtain a different purge rate.Note that the EXT250M pump is supplied with a VRX10 vent-restrictor fitted in the vent and purge ports.You can fit the vent-restrictor to the TAV vent-valve, to the vent-port adaptor or directly to the vent or purge port of the EXT255H and EXT250M pumps.
VRX70 Vent Restrictor B58066025 (B58066025)
Fit a VRX vent-restrictor to your EXT pump if you will vent the pump when the pump speed is above 50% of full rotational speed.

XDS ACCOUSTIC ENCLOSURE – 230V NRD797000 (NRD797000)
Edwards acoustic enclosures are the ideal noise reduction solution for use in a laboratory or an industrial environment. The specially designed soundproof enclosures are made of materials with high noise absorption, reducing vacuum pump noise by up to 9 dB(A), with no impact on vacuum pump efficiency.

EM18 + 28/EMF Oil Return Kit A50420000 (A50420000)
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.
