The Zeus Hydratech Desiccant Breather delivers next-generation protection for hydraulic and fluid power systems.

Designed to replace standard breather caps, it provides a smarter, more efficient way to keep your equipment clean and dry.

As air enters the system, it’s purified through a dual-action filtration process that removes both airborne particles and moisture before they can cause harm.

By keeping contaminants and humidity out, the Desiccant Breather helps extend component life, reduce downtime, and lower maintenance costs. Whether your equipment operates in harsh industrial environments or demanding field conditions, Zeus Hydratech ensures that every system breathes clean, dry air — safeguarding performance and reliability.

Zeus Hydratech Desiccant Air Breather – Key Features

The Zeus Hydratech Desiccant Air Breather combines advanced particulate filtration, oil mist collection, and high-capacity silica to protect hydraulic and lubrication systems from moisture and contaminants. Its reinforced centre tube ensures uniform airflow, while the transparent ABS shell allows easy inspection of silica condition, supporting optimal maintenance intervals and reliable system performance.

1. Centre Tube

Constructed from durable nylon, the centre tube provides structural support and ensures uniform airflow through the silica gel for maximum moisture absorption.

2. Oil Mist Collector

Polyurethane foam captures oil mist and evenly distributes airflow over the filter media and moisture-absorbing silica gel, enhancing overall efficiency.

3. Secondary Filter Layer

An additional filtration stage prevents any migration of silica particles, adding an extra layer of protection for your system.

4. Moisture Absorbent Silica Gel

High-performance silica gel removes moisture effectively and can hold up to 40% of its own weight, keeping your equipment dry even during shutdowns.

5. Transparent Outer Shell

The ABS clear housing allows for quick visual inspection of the silica gel’s condition, ensuring timely replacement and optimal maintenance intervals.

6. Air Intake Design

Intakes open according to airflow demands while providing moisture protection during shipping or storage.

7. Filter Media

1-micron absolute filtration is provided by durable polyester media, preventing fine particulates from entering the system.

8. Sure-Fit Connection

Designed for easy installation, the sure-fit connection replaces traditional filler or breather caps, with adapters available for added versatility.
