Cross Replace Desiccant Breathers For DC-VG Series

Cross replace DC-VG desiccant breathers has a check valve. The check valve provides a system increase without excessive pressure, and only works when necessary. This product mechanism can prevent premature saturation of silica gel and prolong the life of the product.

SINFT VentGuard DC-VG Series

SINFT VentGuard DC-VG Series

SFT-VG-2 Vent Guard Detail

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 body, which permits 10% greater volume 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.
