Eaton Crouse-Hinds Redapt DP-E Series M20 316L Stainless Steel Breather Drain (DPE3004S3)

The Eaton Crouse-Hinds series Redapt DP-E Series (DPE3004S3) increased safety breather drain provides a certified, maintenance-free solution to continuously evacuate condensation and equalize internal barometric pressures within electrical enclosures installed in hazardous industrial locations. Engineered specifically for explosive atmospheres across oil refineries, offshore drilling rigs, chemical plants, and marine terminals, this unit mitigates moisture-induced internal corrosion, tracking, and electrical short circuits before catastrophic downtime occurs.

Precision-machined from premium AISI 316L stainless steel, this breather drain delivers exceptional resistance to salt spray, aggressive washdowns, and sour gas environments. The assembly features a high-density polyethylene (HDPE) permeable core paired with a 3-hole drain layout and a specialized castellated locknut, enabling rapid liquid gravity drainage while simultaneously breathing clean air across an operating temperature range of -50°C to +85°C (NBR seal rated -30°C to +80°C).

Key Features:

✅ Ex eb (Increased Safety) and Ex tb (Dust Ignition Proof) Zones 1, 2, 21, and 22, plus Class I, Div 2 / Class I, Zone 1
✅ Marine-grade AISI 316L stainless steel unplated construction superior resistance against chemical attack and offshore corrosion
✅ Ingress Protection rated to IP66 (EN/IEC 60529) and Enclosure Type 4X (CSA/UL 50/514B) captive Nitrile (NBR) face seal
✅ ISO Metric M20 x 1.5 pitch male thread with 15.0 mm thread length for secure clearance and threaded-entry mounting
✅ High-Density Polyethylene (HDPE) particulate and moisture-permeable core to balance breathing and filtering efficiency
✅ 3-hole peripheral drain pattern for multi-directional discharge of condensation
✅ Included castellated locknut ensures fluid bypass directly from enclosure floor into exterior drain channels
✅ Broad operating temperature tolerance: -50°C to +85°C assembly (-30°C to +80°C with standard NBR seal)
✅ Certified globally under ATEX, IECEx, cCSAus, INMETRO, UKEX, and EAC directives

FAQs:

Where should this breather drain be installed on the enclosure?
The breather drain must always be installed at the lowest possible point of the enclosure baseplate to permit complete gravity evacuation of accumulating condensate.

How does the castellated locknut function during installation?
When mounting through a clearance hole (Ø 20.0 mm to 20.5 mm), the slotted teeth of the castellated nut must face directly against the internal wall to allow standing condensation to drain through the slots into the fitting.

Can the internal HDPE filter element be cleaned?
Yes, the porous HDPE core can be inspected and backflushed using clean water or low-pressure compressed air during standard plant maintenance turnarounds.

What is the recommended tightening torque for installation?
The fitting should be torqued to approximately 27.0 N·m for M20 stainless steel to ensure full compression of the captive O-ring without deforming the sealing seat.
