CBA UFI Air Filters

UFI Air Sentry Filters are desiccant breathers designed to ensure maximum protection of hydraulic tanks by removing water vapour and solid contaminants. The three-stage filtration system includes 2 µm particulate filters and a silica gel bed with high adsorption capacity (up to 40% of its weight). Available in the D-10+ series in ABS plastic and the R-10+ series with a reinforced steel base, they operate with a nominal flow rate of 1,000 l/min.

Description

CBA UFI Filters: Compact Air Breathers for Tank Protection

The UFI Filters CBA series represents an effective and durable solution for filtering incoming air in hydraulic fluid reservoirs. These devices, essential for compensating fluid level variations and preventing the ingress of particulate matter, are designed for simple manual installation, making them ideal for numerous industrial and mobile applications.

Construction Features and Materials

CBA filters stand out for their solid construction, designed to withstand harsh operating environments:

  • Body, Flange and Basket: Made entirely of galvanized steel, they offer high resistance to corrosion and atmospheric agents.
  • Cap: The chrome-plated finish of the top cap provides additional protection and durability.
  • Filter Element: The internal element is not replaceable and is available in two filter media variants to suit different levels of environmental contamination:
    • Impregnated Cellulose (CC): For fine filtration down to 3 µm.
    • Polyurethane Foam (PE): For coarser filtration down to 10 µm.

Performance Specifications

These filters are designed to handle significant air flows in relation to their compact size:

  • Maximum Flow Rate (Qmax): Up to 750 l/min for the polyurethane media models of the 21 series, and up to 450 l/min for the cellulose versions of the same series. The smaller versions (series 11) handle flow rates from 150 to 250 l/min.
  • Operating Temperature: The operating range extends from -25°C to +110°C, ensuring reliability under varying climatic conditions.

Fluid Compatibility

CBA UFI Filters are fully compatible with a wide range of standard hydraulic fluids, including HH, HL, HM, HV and HTG according to ISO 6743/4.

Models and Connections

The range is available in two main sizes, differentiated by flow capacity and type of BSP threaded connection:

  • CBA 11: 1/4″ BSP connection, ideal for smaller systems.
  • CBA 21: 3/4″ BSP connection, for higher air flow rates.
