HC9021FHT4Z Supralon high-collapse hydraulic element, 25 µm
Entry Two Resources is an official channel partner of Pall (Malaysia) Sdn. Bhd., specialising in asset protection filtration for the oil & gas and power generation industries.
Overview
Pall HC9021FHT4Z
A Supralon glass-fibre element built on Pall’s high-collapse medium, rated 25 µm at βx(c) ≥ 2000, in the 4-inch length. High-collapse construction is what lets it sit in Pall’s 9021 Series non-bypass pressure assembly, protecting servo and proportional valves downstream.
Elements in this family protect hydraulic power units, governor and control systems, gearboxes and lube circuits on rotating equipment — offshore and onshore. This is the family behind our recurring Pall supply to the power generation industry in Malaysia.
