Hi all
I have found on the Farnell element14 site these EXEBDM20SS6EXEBDM20SS6 BREATHER DRAIN, ENCLOSURE
But I cannot find the maximum flow they will allow.
Ideally I would like an Ex e rated vent and inlet connection to tube a flow (approx 2m3/hr) of high quality (dust, oil and moisture free) instrument air into a steel duct.
The system is Ex e rated, and the notified body won;t let me connect this high quality air system directly to it. They are insisting it needs to flow through an Ex e rated inlet bulhead connector, and out through an Ex e rated vent.
Oddly, they are happy using the instrument air directly for the Ex p (purged) enclosures, so I'm a bit confused but there you are.
Anyone know of anything? Or what the max flow of these hoffman ones is?
regards
Doove
