ATEX/IECEx - Ex e or d rated vents - does anyone know of any large ones?

Hi all

 

I have found on the Farnell element14 site these  EXEBDM20SS6EXEBDM20SS6 BREATHER DRAIN, ENCLOSURE

http://uk.farnell.com/hoffman-enclosures/exebdm20ss6/breather-drain-enclosure/dp/2447964?storeId=10151&storeId=10151&CMP=ADV-C-UK&catalogId=15001&krypto=fL4JjHRRmgARABy9ZSJDl6LjrKg2WIXHkp8GdOU%2Br4pXT0ApatkIRAH5hQ3hijH9S2Y2PEBMChTkmTXwt4rZKhIiTkG4GlFWiRu67ynSQ%2BINwEE%2BoGeImr0L7NtgCj9V7dwTSZ7TAIV3WXMG8WdtWGkFK16pBd5q9MrRu0ZBW5LOcatDekqRrUoVx%2B9bF5k6kJjXikUhwG9dXG7EHHXnomoOEGqEO5RTz0kYVgw45RYBVMeFJ3CL9V%2FIx%2F%2F0iYuGOzLxM%2BI8m8OVdsLYeuNTNkEugOjz8oPsXvDM%2B9PLCg%2BzwKBu7%2FG%2BclG3%2BiIhE8DxPAwrmDhKbjYWTZODnMbmaFohQYHciO1EjNbJ0pLsybBwXpoLyrK9hhaqsUF3xUHrgmOCZ3ZcqJubAfk7PEVmty7OJj3mJlTVe0CtoN8uczPZxAQryXYvkjL5SIOdHWFu6HRw%2B2vTgnJf2LP%2ByXJAvsZq0D3gC5a02vRrvubzhLC5kDWnpIVEr16oM%2FdxH6k1KIL5Vs%2FGzHUSO6wpoOMxtTx4ok2LBCwe%2BVbGTdS9NhSokIfxEkPgaanSEhDxc9h40yAkmpYH9KtpDsjjaG0xcBoqTZRF4UenGP%2BiVx%2FHT7yV7R5RV%2B5cFpPpmEGZIE29pLA3T6siX10lsO94OAzakFhFzk%2FF80Wfaang2OkPYzLfvXE92%2Fu1qEzV9ojghrVzzX0pE2X863pofG2GLNBvMXoG%2BK6VQeTSL%2FgTvYZ95xBuyd4ITUqEhpsSbniS3Y9Eh6F%2FiORJSyW6rM8zUXF%2BEM9JfWXM69kzGs1WrnXX5SQN8087TTZfi6CWnO0qh9XAA1mfpD6IK5VnV5ZAcBIhnQwgX8whjbWwkx3yefOPN%2BsNdFdx3gzW%2B5mMpWwo9rTqZDTRjNi6n48LaiS7SXzdX99TbOZ3Ubsky1EdJ43cW4YpCeQ1d7gxtOUTrnLcpuEKZOWNtKDFZD%2BDRtgdrCQ41%2FtTMHNc72KhCxKtT5xM2aEMsUI9fcZC27631NH5wwCA9WKc%2BtNxsSFp05hoM6Chb2wHQBpRPxfsvpSakjW76LkfKqdHy3uXU%2FXuOREc2WkdpH81JR0ZrjZqk6ecSGSQDqYtB3agYzUZPlDYWUbiomdJLz1bHIkjpo183lRSnaFuYriFtxU7hxsx6XPaasVQWr45cb6xhO1NAhtx4JPxiuBUzVQ%2FTwaKhN%2BDxSN5n4DdIPPt2oaLPiBzpmY9GtW3YNjCgtj2KI52YpSbHJ%2FXvB1CzYKII%2FTtckF0cg8jf%2BIZdbs0t02OH5No98OLv7JPkAtw%2BWzvYbGZzVyCSIePGsg%3D

 

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

    Hi David,

     

    I've contacted my internal people. They have directed your question to tech support. So, when I get answer, I'll post it here.
