Crouse-Hinds ECD18 – Frequently Asked Questions

1) Is a combination breather and drain approved for a Class I Division 1 area, or do I need Division 2 only?
Class I, Division 1 is the rating on the ECD18, which covers locations where ignitable gas or vapor concentrations can be present during normal operation. Equipment rated for Division 1 is also acceptable in Division 2 of the same gas group, so one part covers both zones on a mixed site. It is built to NEC/CEC standards.
2) Do I need a separate breather and a separate drain, or does one ECD18 do both jobs?
One unit does both. The ECD18 is a combination breather/drain, so it vents the enclosure to equalize pressure and allows accumulated condensate to drain through the same fitting. Where you have a tall or multi-compartment enclosure, the usual practice is a breather high and a drain low, so a single combination fitting at the low point is the common choice on smaller boxes.
3) Will a stainless breather/drain hold up in a refinery or coastal salt-air environment?
Construction is stainless steel with a neoprene tube, which is the material choice for corrosive duty, washdown, chemical exposure and salt air. That is a step up from a plain malleable iron or feraloy breather, which relies on its paint or plating to survive the same atmosphere.
4) How much clearance do I need below the enclosure to fit this breather/drain?
Allow for a 3.1 inch overall height, with a body footprint of .88 by 1.02 inches. Mounted in a bottom hub, that 3.1 inches is what hangs below the enclosure, so check it against any strut, curb or skid rail under the box. At .23 lb it adds no meaningful load to the enclosure wall.
5) Why does a sealed explosionproof enclosure need a breather at all?
Sealed boxes in outdoor classified areas heat and cool with the day, and that pressure cycling pulls humid air in past gaskets, where it condenses on terminals and insulation. The ECD18 gives the enclosure a controlled path to breathe and to shed that condensate, while keeping the assembly suitable for Class I, Division 1 service. Typical duty is petrochemical plants, oil and gas production, refineries, tank farms and solvent storage.
6) What part number do I put on the purchase order for the 1/2 inch stainless combination breather/drain?
Order Crouse-Hinds ECD18. It is a single configuration, 1/2 inch trade size in stainless steel with a neoprene tube, so there is no finish, material or thread option to specify beyond the part number itself.
7) Can I install this breather/drain in a non-classified indoor panel?
Yes. Equipment listed for Class I, Division 1 may be used in unclassified areas, so the ECD18 is fine in an ordinary outdoor or washdown panel if you want the stainless body. It is specified for hazardous/classified locations, so for a plain indoor panel you are paying for a rating you will not use.
