Eaton Vickers BR110 H2O-GATE Vent Filter Breather

Eaton Vickers H2O-GATE BR110 Vent Filter Breather

Eaton Vickers H2O-GATE BR110 Vent Filter Breather MPN: BR110 / C1CL72 The Eaton Vickers H2O-GATE BR110 Vent Filter Breather is a high performance reservoir moisture and particulate filtering device for heavy duty industrial hydraulic power units (HPUs), marine deck equipment and mobile fluid power systems.

Unlike typical desiccant silica-gel breathers, which eventually get saturated and require frequent media replacement, the H2O-GATE BR110 uses a patented, reversible flow-through water barrier medium. In the inhalation phase of the system (liquid level decreases and air enters) the media inhibits airborne solid particles down to 3 microns and prevents water vapor ingression. During the exhalation cycle (liquid level rises or thermal expansion pushes out air) moist reservoir air is released thru the filter, removing retained moisture and dynamically replenishing the capacity of the medium without chemical degradation.

Model Details

• Manufacturer Part Number (MPN): BR110
• Eaton Ordering Code: BR110 / C1CL72
• Design Series: H2O-GATE BR Series
• Mounting Connection: 1-1/2″-16 UN Straight Thread Female (direct spin-on or adapter mount)

Key Features

1. Reversible Regenerative Moisture Barrier: Proprietary H2O-GATE media continuously expels reservoir humidity during exhalation cycles, restoring moisture retention performance without silica gel saturation.
2. High-Efficiency Particulate Retention: Provides 99.7% efficiency at 3 microns preventing fine silting and varnish-forming particulates from contaminating hydraulic fluids.
3. Rugged ABS & Steel Construction: Features a UV-stable ABS housing rated to 121°C (250°F) paired with a plated steel center core to prevent media collapse during rapid air displacement.
4. Low Differential Pressure Drop: Engineered for high air exchange rates up to 25 SCFM (708 LPM), minimizing structural vacuum or over-pressurization stress on tank walls.

Applications

• Marine & Offshore Deck Machinery: Anchor windlasses, hydraulic winches, davits, steering gear HPUs, and crane hydraulic circuits exposed to sea spray and high humidity.
• Industrial Hydraulic Power Units (HPUs): High-duty cycle power packs in metal stamping, plastic injection molding, and primary metals plants.
• Gearboxes & Lube Oil Systems: Closed-loop gear reducers, heavy drive gearboxes, and circulating lube oil reservoirs in harsh environments.
• Mobile Construction Machinery: Excavators, pile drivers, and mobile cranes subject to extreme ambient temperature shifts and heavy air exchange volume.

Equipment Compatibility

• The BR110 features an integrated 1-1/2″-16 UN female straight thread interface. It can be directly installed on standard Eaton/Vickers flange adapter plates or adapted to standard pipe tanks using OEM interface kits:

Frequently Asked Questions

How does the Eaton Vickers H2O-GATE BR110 differ from standard desiccant silica breathers?

Standard silica-gel desiccant breathers absorb moisture chemically until they saturate and turn color, requiring full unit disposal. The Eaton H2O-GATE BR110 uses a physical moisture barrier that blocks incoming water vapor during tank inhalation and uses outgoing dry/warm reservoir air during exhalation to blow off trapped moisture, effectively self-regenerating the filter element.

What is the filtration rating and flow capacity of the BR110 vent breather?

The BR110 provides an absolute particulate retention efficiency of 99.7% at 3 microns with a maximum air exchange flow rating of 25 SCFM (708 LPM).

What mounting thread size does the BR110 breather use?

The BR110 breather features a female 1-1/2″-16 UN straight thread. It can be mounted directly or adapted using standard 3/4″ NPT, 1″ NPT, or 6-bolt ISO/DIN bayonet adapters.
