Desiccant Breathers
Protect Fluid Systems from Moisture & Contamination b
ZEOZORB® Desiccant Breathers provide active protection against moisture intrusion and airborne particulate contamination in hydraulic systems, gearboxes, transformers, and storage tanks.
Designed to replace standard OEM breather caps, they help extend lubricant life, reduce internal corrosion, and improve equipment reliability.
Available Models
Why Desiccant Breathers Matter
Reservoirs and tanks constantly inhale and exhale air due to:
✔ Temperature changes
✔ Fluid level fluctuations
✔ Pressure differentials
Without proper protection, this airflow introduces moisture and particulate contamination into lubricants and hydraulic fluids. Over time, this leads to:
- Accelerated fluid degradation
- Internal corrosion
- Increased component wear
- Reduced equipment efficiency
Desiccant breathers act as the first line of defense.
How ZEOZORB® Breathers Work
As air enters the system:
✔ Multi-layer filtration removes airborne particulate
✔ ZEOLITE desiccant absorbs harmful moisture
✔ Activated carbon filtration helps extend service life
✔ Bi-directional airflow protects during both intake and exhaust cycles
The indicated ZEOLITE beads change from blue to beige when fully saturated, providing a clear visual replacement signal.
Key Features
✔ ZEOLITE adsorption capacity up to 20% by weight
✔ Multi-layer filtration system (diffusion filters, PTFE, stainless steel)
✔ UV-resistant polycarbonate housing
✔ Broad operating range: -40°F to 248°F (-40°C to 120°C)
✔ Non-mechanical airflow control plenum
✔ Standard 1” multi-thread connection for flexible installation
Built for durability in industrial environments including oil & gas, mining, manufacturing, agriculture, logistics, and power generation.
Common Applications
ZEOZORB® Desiccant Breathers are commonly installed on:
- Hydraulic reservoirs
- Gearboxes
- Storage tanks
- Transformers
- Mobile equipment
- 55-gallon drums and totes
They are suitable for both stationary and mobile industrial systems.
Maintenance & Replacement
ZEOZORB® breathers are disposable and designed for simple installation.
Replacement is required when:
✔ All blue indicating beads turn beige
✔ Maximum adsorption capacity is reached
Routine inspection should be included in plant maintenance schedules based on environmental exposure and airflow demand.
