Desiccant breathers play a vital role in safeguarding and extending the lifespan of industrial equipment. Here are five compelling reasons why their utilization is imperative.

  1. Moisture Protection: Desiccant breathers effectively absorb any moisture present in the surrounding air, preventing its entry into equipment such as transformers and gearboxes. This safeguard helps shield the equipment from rust and corrosion, significantly prolonging its operational life.

  2. Contamination Prevention: Moisture can lead to contamination of lubricants and other fluids within the equipment, resulting in reduced performance and increased wear and tear. Desiccant breathers act as a preventive measure by eliminating moisture from the air before it enters the equipment, thus averting potential contamination.

  3. Enhanced Performance: By eliminating moisture and maintaining dry conditions, desiccant breathers contribute to improved equipment performance. This includes increased efficiency, extended longevity, and prevention of breakdowns or malfunctions.

  4. Reduced Maintenance Costs: Desiccant breathers minimize the need for maintenance and repairs by preventing rust, corrosion, and contamination. Consequently, significant cost savings can be achieved throughout the equipment’s lifespan.

  5. Versatility: Desiccant breathers are versatile and find utility across diverse industries and applications such as power generation, oil and gas, chemical and petrochemical, food and beverage, among others. Their wide-ranging effectiveness makes them an essential component for numerous equipment protection needs.

Air Sentry Breathers are specifically designed to shield equipment from moisture, dust, and other contaminants by effectively absorbing and removing them from the surrounding air. These breathers employ a two-stage filtration system comprising a primary filter that removes larger particles and a desiccant bed that eliminates moisture. The desiccant bed is composed of silica gel and can be recharged or replaced as needed to maintain optimal functionality. The Air Sentry Breathers are suitable for various applications, including power generation, oil and gas, chemical and petrochemical, food and beverage, among others. They are available in different sizes and configurations to accommodate diverse requirements and environmental conditions.

Airsentry breathers, your equipment will last longer

Air Sentry breathers first set the gold standard with their introduction in 1997. Achieving near total control of fluid system contamination, Air Sentry has led the industry by improving productivity, prolonging fluid life, reducing maintenance costs and controlling expensive downtime. The pace of a competitive world absolutely requires this level of performance.


Air Sentry breathers are designed to replace the breather cap or air filter on gear boxes, hydraulic fluid reservoirs, bulk storage tanks, oil drums, oil-filled transformers and other fluid reservoirs.

How it works

Air Sentry desiccant breathers adsorb water from the air before it enters your fluid system and remove particulate contaminants as small as 2 microns.
The silica gel changes color as it becomes depleted, turning from gold to dark green. It’s easy to identify the condition of a breather and quickly replace it, maintaining the cleanliness of the fluid reservoir.
