Brownell Desiccant Breathers

Moisture can ruin fluids like transformer oil or break fluid, fast. That's where the Brownell Desiccant Dryers come in. They're a simple and effective way to protect your fluids from water contamination.

Just attach the dryer to your tank or drum's breather port, that's it. As air flows in, the desiccant inside traps and removes water vapour before it can get to your fluid. It's hands-off protection you can rely on. Whether you're working with industrial tanks, storage drums, or sensitive machinery, they help keep your fluids dry and uncontaminated, no matter the application.

Industrial Drum Vent Breathers:

Worried about moisture or particles getting into your storage tanks or drums? The Industrial Vent Breathers are designed to keep your hydroscopic fluids safe, even during active operation.

Each breather is filled with a silica gel that changes colour from orange to green as it absorbs moisture. So you'll always know exactly when it's time to replace it, no guesswork needed. Both the standard and heavy-duty versions come with built-in filters to stop harmful particles from entering your system. That means cleaner equipment and longer-lasting fluids.

Transformer Breathers

Even a tiny amount of water vapour can cause serious issues in your transformer. It can weaken insulation, break down cooling oils, and eventually lead to equipment failure. That's why humidity control isn't optional, it's essential.

Designed to suit systems from 1250 kVA to 750 MVA, they're a perfect fit for a wide range of transformers. Each breather comes pre-filled with low-dusting Envirogel, which offers 25% moisture adsorption. A handy colour-change indicator will also show you exactly when it's time to replace the gel. With a temperature range of –50°C to +70°C, a two-way, low-pressure valve, and a vandal proof, weather-resistant build, they're ready for any environment, indoors or out.

R-Series Transformer Breathers:

Need an easy way to protect your equipment from moisture? The R-Series Breathers are a smart, durable choice that is designed for long-lasting use and effortless monitoring.

Each breather is made from UV-stabilised polycarbonate, so it stands up to those tough environments. The clear body makes it easy to check the desiccant level at a glance. Whether you're working with small tanks or larger systems, the R-Series comes in three different size options, so you can choose what fits best for your setup.

Easy to install, Easy to maintain, Built to perform.

Premium Transformer Breathers:

Got a large tank or high-capacity transformer to protect? This range of heavy-duty breathers are built to block moisture and keep your equipment performing at its best even in the toughest conditions.

The container is made from phosphate-treated, powder-coated mild steel, giving it long-lasting corrosion resistance. A clear, UV-stabilised polycarbonate window lets you easily check the desiccant condition, so you know exactly when to top it up.

If you need a rugged, reliable breather for critical equipment, this range delivers both long-term protection and easy maintenance.
