FPO UFI delivery air filter

The FPO UFI delivery air filter is a high-pressure spin-on solution designed for hydraulic circuits. With an aluminum alloy head and a steel cartridge body, it supports operating pressures up to 35 bar (FPO1+ series) and maximum flow rates of 250 l/min. It offers a wide range of FormulaUFI filter media for precise filtration. Equipped with an integrated bypass valve and compatible with ISO 6743/4 fluids, it ensures reliability in operating conditions from -25°C to +110°C.

Description

High-Pressure Spin-On Filters FPO UFI Series: Performance and Ease of Maintenance

The FPO series by UFI Filters sets the standard for high-pressure delivery filtration with spin-on technology. These filters are designed to protect sensitive hydraulic system components, combining the robustness required for high pressures with the practicality of quick cartridge replacement.

Construction Features and Materials

FPO filters are built to withstand intense operating stresses:

  • Head: Made of aluminum alloy, lightweight yet extremely strong.
  • Cartridge Body (Housing): Made of steel to ensure structural integrity under pressure.
  • Bypass Valve: Made of polyamide, integrated to ensure continuous flow (available settings: 1.7 bar or 3.5 bar).
  • Seals: Standard NBR Nitrile, with optional FKM Fluoroelastomer on request for special fluids or high temperatures.

FormulaUFI Filter Elements

The series uses advanced UFI filter media technology to meet every contamination requirement:

  • FormulaUFI.MICRON (FA, FB, FC, FS, FD): Inorganic glass microfiber with absolute filtration ratings from 5 to 21 µm (ß > 1,000), for maximum protection.
  • FormulaUFI.CELL (CC): Impregnated cellulose rated at 10 µm.
  • FormulaUFI.WEB (ME): 60 µm metal mesh.

The filter element is designed to withstand a differential collapse pressure of 1 MPa (10 bar).

Performance and Technical Specifications

The FPO UFI delivery air filters offer top-level performance:

  • Operating Pressure: Up to 3.5 MPa (35 bar) for the FPO1+ series and 2.5 MPa (25 bar) for the FPO2+ series.
  • Maximum Flow Rate (Qmax): Up to 250 l/min.
  • Operating Temperature: From -25°C to +110°C.
  • Connections: Available with BSP or NPT threads, in sizes 3/4″ and 1″.

Maintenance and Accessories

The spin-on configuration allows quick and clean replacement of the exhausted element. The filters are prepared for the installation of clogging indicators (visual, electrical, or with thermostat) to effectively monitor filter condition and plan maintenance.
