Oil & Gas Filtration Products for Subsea Hydraulic Power Units (HPU)

Swift Filters is top choice for meeting subsea equipment filtration requirements and standard terrestrial requirements such as wear reduction, lubricity, viscosity range, achieving ISO 4406 fluid cleanliness standards pre-deployment.

Our subsea filter elements are manufactured to withstand extreme conditions including high pressures, corrosive environments, and long service intervals, often with minimal maintenance opportunities. 

We offer offshore-ready subsea filtration products are constructed from high-grade materials such as corrosion-resistant 316 SS, Inconel, or anodized aluminum for saltwater resistance. Engineered for high dirt-holding capacity, high differential pressure (ΔP), cyclic loads, and fluid compatibility, they ensure reliable performance with long life under these challenging conditions.

FILTRATION PRODUCTS FOR HPU (HYDRAULIC POWER UNIT) APPLICATIONS
