L1.0406-43 : Argo Ventilating Filter, 32GPM nominal flow, 1/4" NPT ports

The oil levels in the tanks of hydraulic systems are subject to continuous variation due to temperature changes and the operation of cylinders and pressure vessels. In order to prevent over pressure in the tanks, an exchange of air with the external atmosphere is necessary. By the use of a ventilating fi lter, the outside air that is drawn in is filtered and the ingress of dust is therefore prevented. The ventilation openings are designed that dust on the surface of the tank is not drawn in, and that the ingress of spray and rainwater is largely prevented. The use in marine applications presents no problem due to the use of synthetic materials and stainless steel.
