National Spencer Disposable Breather – Silica Gel – 10 Inch x 5 Inch – D-108 – Grease Guns

Will satisfy most applications involving hydraulic reservoirs, lubrication and fuel storage tanks, transformers, pumps and gearboxes. The Air Sentry Breathers replace the standard breather or vent cap on virtually all types of industrial equipment, storage tanks, and transformers. They prevent destructive contaminants from entering fluid reservoirs and tanks as air is breathed in and out due to thermal expansion or fluid level changes. Fluid contamination is one of the primary causes of wear and lubricant failure in industrial equipment.

The D-108 Breather is rated for airflow of 100 cfm (750 GPM) and is connected to the tank by a 2″ male pipe thread.
