Gearboxes are used on various types of industrial machinery to provide increased torque while reducing speed from one type of rotating power source to another using gear ratios. A gearbox can be set up to do the opposite and provide an increase in speed with a reduction of torque. Some of the simplest gearboxes merely change the physical direction in which power is transmitted.
Gearboxes are used in many applications, such as wind turbines, conveyors, draglines, bridges, wastewater treatment pumping systems, and many other large pieces of machinery that require a power source.
The Air Sentry® X-100 is the most commonly recommended breather for gearboxes. Airflow requirements for gearboxes are usually very low, as the fluid level rarely changes. Dual check valves in the top cap open at minimal pressure changes, allowing air to flow in and out as needed while maximizing the life of the silica gel. Replacement silica gel cartridges allow for easy, economical change out that create no down time for the equipment being protected from dirt and moisture.
