Hayward EC65 FILTER HEAD W/VAC RELIEF

The Hayward EC65 Filter Head with Vacuum Relief serves as the primary structural cover and pressure-containment dome for the Perflex extended-cycle D.E. filtration system. Precision-molded from a high-impact, UV-stabilized copolymer, this component is engineered to withstand high internal hydraulic pressures and the environmental stressors of an outdoor equipment pad. Its primary mechanical function is to provide a secure housing for the internal tube nest assembly and the manual bump mechanism, while the integrated vacuum relief valve acts as a critical safety feature to prevent tank implosion or suction entrapment during drainage or pump operation. The head features dedicated ports for a pressure gauge and air relief assembly, allowing the operator to monitor system performance and safely bleed trapped air. Designed with a wide flange to accommodate the heavy-duty diaphragm gasket, it ensures a watertight seal when secured to the filter tank. For shipping and logistical purposes, the estimated weight of the Hayward EC65 Filter Head with Vacuum Relief is approximately 12.5 pounds in its retail protective packaging, while the actual dry weight of the molded head unit is roughly 10.2 pounds.
