Protect Your Equipment
From Moisture &
Particle Contamination
Industry-leading desiccant breathers from Des-case, Brownell and RMF
Supplying Industry-Leading Vent Breathers
Find the right solution for your application from our most popular desiccant breather ranges.
Moisture Contamination Could Be Costing You Thousands
Every time your equipment breathes, airborne moisture and contaminants can enter your reservoirs, storage tanks and gearboxes.
Over time this can lead to lubricant degradation, corrosion, increased wear and costly equipment failures.

What Happens When Moisture Enters Your System?
Moisture Contamination Is One Of The Biggest Causes Of Lubricant Failure
Every time a hydraulic reservoir, gearbox, storage tank or fuel tank “breathes”, outside air is drawn into the system. That air often contains moisture, dirt and airborne contaminants.
Over time, this contamination can damage lubricants, accelerate component wear and lead to costly unplanned downtime.

How Desiccant Breathers Protect Your Equipment
Every time equipment heats up and cools down, air moves in and out of the reservoir. Desiccant breathers remove contaminants before they can enter your system.
Equipment Breathes
Temperature and fluid level changes cause air to enter and leave the reservoir.
Air Is Filtered
Particulate filters capture airborne dust and contaminants before they enter the system.
Moisture Removed
Silica gel absorbs water vapour from incoming air before it reaches the oil.
Cleaner Equipment
Reduced contamination helps extend lubricant life, improve reliability and reduce maintenance costs.
The Real-World Impact
Unchecked moisture contamination can lead to significant operational and maintenance costs throughout the life of your equipment.
- ● More frequent oil changes – higher lubricant and disposal costs.
- ● Increased maintenance time – engineers spending more time on reactive repairs.
- ● Reduced equipment reliability – unexpected breakdowns and production interruptions.
- ● Higher operating costs – wear-related failures can cost far more than prevention.
Even small amounts of moisture can accelerate lubricant degradation, corrosion and component wear, leading to avoidable maintenance costs and downtime.
The Solution: Stop Contamination Before It Enters
Desiccant breathers remove moisture and airborne particles from incoming air before it reaches your equipment.
By fitting a desiccant breather to hydraulic reservoirs, gearboxes, storage tanks and fuel tanks, you can:
- ✓ Reduce moisture ingress
- ✓ Keep lubricants cleaner for longer
- ✓ Extend oil and component life
- ✓ Improve equipment reliability
- ✓ Reduce downtime and maintenance costs
Selecting the correct desiccant breather can significantly improve lubricant cleanliness, reduce maintenance costs and extend equipment life.
Common Applications for Desiccant Breathers
Desiccant breathers help protect lubricants, fuels and critical equipment from moisture and airborne contamination across a wide range of industrial applications.
Hydraulic Reservoirs
Protect hydraulic fluids from moisture and airborne contamination, helping to improve system reliability and extend component life.
Gearboxes
Reduce condensation and particulate ingress that can accelerate wear, corrosion and lubricant degradation.
Bulk Oil Storage Tanks
Maintain lubricant cleanliness during temperature fluctuations and breathing cycles.
Diesel Fuel Storage Tanks
Minimise moisture ingress that can contribute to fuel degradation, microbial growth and filter blockages.
Transformers
Protect insulating oils from moisture contamination that can reduce dielectric strength and transformer reliability.
Wind Turbine Gearboxes
Prevent moisture and dirt ingress in demanding environments, helping to extend lubricant and gearbox life.
Mobile Plant & Equipment
Improve contamination control in hydraulic systems operating in dusty and challenging outdoor conditions.
Industrial Process Tanks
Protect valuable fluids and chemicals from airborne moisture and particulate contamination during storage and operation.
