"At least 75% of gearbox failures are a result of contaminated lubricants."

The Hydroguard™ breather is the ideal solution for the management of lubricant condition in washdown applications or high humidity environments where there are increased incidences of gearbox and lubricant failure due to moisture ingress.

Prevent In-Service Lube Degradation

Ideal for gearboxes and other low flow applications (such as pumps, bearing houses and storage drums/totes), Hydroguard offers superior protection and optimizes reliability of lubricants and related machinery.

Next Generation Breather Technology

The patent-pending hybrid design combines the functions of filtration, desiccant and membrane technology into one cost-effective package to effectively eliminate ingression of dirt and water through the filler/breather ports.
A major benefit of the Hydroguard breather is that lubricants are virtually isolated from surrounding contaminants. The system `breathes' yet can withstand driving rain or direct wash-down spray. A diaphragm allows for expansion and contraction of air within the casing as a result of temperature variation during steady state operations. Enclosed filter media protects down to 3µm, while the desiccant stack prohibits moisture entry.

Controlled Breathing Mechanism

What really differentiates the Hydroguard breather from competing models is its 'controlled breathing' mechanism. Check valves provide slight system pressurization that allows for controlled breathing without excessive temperature build-up. The system breathes only when pressured to do so, and then the air is cleaned and dried before it is introduced into the system, ensuring a clean, dry headspace. This control mechanism also prevents premature saturation of the silica gel and extends the breather time life, a problem not as easily tackled by standard desiccant breathers exposed to extreme moisture.
