Compared with the dust cap or OEM respirator cap on the original equipment, the desiccant respirator can provide a better filtering effect, and even the smallest particles can be well filtered out.

The principle of the desiccant respirator is that when the air is sucked into the device through the respirator, the desiccant filter will remove the particles in it and remove harmful moisture at the same time, ensuring that the desiccant can absorb the moisture inside the water tank during the use or shutdown of the machine , So as to play the role of drying equipment.

We provide various series of respirator products of various brands and a complete range. If you do not find this product, you can directly consult us, we will check our database and provide you with help..

Improved models and more choices


Gearboxes, reservoirs and pumps all “breathe” in use. As air contracts or expands or as entering fluid displaces air in a system, outside air is drawn in from the atmosphere. Unfortunately, this breathed-in air has water and particulate that will accumulate to contaminate your system.
A desiccant breather is a straightforward solution to the problem, blocking moisture and particles from entering. Testing of leading competitors has shown that Sinft-Dri Desiccant Breathers average almost 20% greater moisture-retention capacity versus leading brands.

Our unique design features a longer life, which permits 10% greater life of silica gel desiccant beads when compared to leading competitors.

Advanced Silica Gel

Desiccant removes water from air prior to it entering your system, tank or equipment.

Built-in Status Indication

Desiccant gel changes color from blue to pink to indicate that it is removing moisture, as well as when to replace the breather.

Step Up to Superior Protection

This breather unit is a marked improvement over the customary dust caps or OEM breathers on equipment. When contaminated air enters the top of the breather, it passes through layered filter media, preventing solid particles from entering the breather and causing undue wear to your equipment surfaces. Filtered air passes through a bed of Sinft-Dri™ silica gel, which removes harmful moisture from the air. The silica beads also work to attract moisture from inside the equipment reservoir during service or shut-down, keeping the equipment dry. The addition of check-valves in our CV breather is ideal for low-flow and intermittent operations in high humidity conditions.
Standard breathers provide simple, yet dependable protection from moisture and particulate contamination in lubricants and equipment across multiple industries and applications. These versatile breathers are five times more effective than the leading non-desiccant breathers, providing optimal defense against humidity for your applications.


For example, a gearbox for wind power generation:

GearboxGearboxes in wind turbines differ from those in high-speed machinery In industrialgearboxes, the progress of failure can occur in weeks, days, or even hours. In windturbines, the impact of contaminants on slower turning gear drives is slow andinsidious. Nevertheless, the mean time between failure(MTBF)for gears andshaft-support bearings can be increased by as much as two to three times by maintaining optimum levels of fluid cleanliness and dryness.
