Hayward EC 75 TUBE NEST ASSY

The Hayward EC75 Tube Nest Assembly is a complete internal filtration core designed for the Perflex high-capacity extended-cycle D.E. filter system. This pre-assembled unit consists of a large array of specialized flexible tubes, or "fingers," held in a rigid vertical orientation by a heavy-duty top and bottom tube sheet. Its primary mechanical function is to provide the maximum possible surface area for Diatomaceous Earth to coat, allowing the system to trap microscopic debris as small as 5 microns for superior water clarity. The entire nest is engineered to move as a single synchronized unit when the external bump handle is engaged; this "bumping" action causes the tubes to flex and shift, effectively shedding the spent filter media and accumulated dirt to regenerate the filter bed without a backwash cycle. Constructed from high-impact, glass-reinforced thermoplastics and chemical-resistant synthetic fabrics, the assembly is built to withstand the intense hydraulic pressures and abrasive environment of a professional-grade pool filtration system. For shipping and logistical purposes, the estimated weight of the Hayward EC75 Tube Nest Assembly is approximately 24.5 pounds in its retail protective packaging, while the actual dry weight of the internal cluster assembly is roughly 21.2 pounds.
