Detailed Product Description
The Role of High-Pressure Hydraulic Filtration
A hydraulic filter is designed to remove microscopic contaminants from hydraulic fluid to protect sensitive pumps, valves, and actuators from abrasive wear. The HF28978 is a high-performance element that utilizes a glass fiber matrix to maintain system pressure integrity and fluid purity. By capturing particles as small as 20 microns at a Beta ratio of 1000, this filter ensures that high-pressure components in heavy excavators and haul trucks remain free of debris that causes internal leakage and catastrophic failure.
Solving System Failure in Extreme Environments
In mining and large-scale construction, hydraulic systems operate under intense thermal and mechanical stress. The HF28978 solves the common issue of seal degradation by utilizing Viton (FKM) seal material, which remains chemically stable and elastic even at temperatures reaching 120°C. This prevents external leaks and ensures that the filter housing maintains a perfect seal under the extreme pulsations of a Doosan DX480 or Komatsu HD785-7 hydraulic circuit.
Why Choose AYREST HF28978?
The AYREST HF28978 is manufactured to meet or exceed the performance of the Fleetguard HF28978 and Donaldson P551210. Unlike standard cellulose filters, our glass fiber media provides a much higher dirt-holding capacity, extending service intervals and reducing the Total Cost of Ownership (TCO) for fleet managers. We focus on the precision of the 110.0 mm inner diameter to ensure a non-bypass fit within the filter head, preventing unfiltered oil from damaging your equipment.
Comprehensive Industry Application
This filter is a critical component for high-capacity machines such as the Doosan DL series wheel loaders and the Komatsu HM350 articulated dump trucks. Its robust design makes it the preferred choice for industries ranging from deep-pit mining to large-scale infrastructure development.
