Fai Filtri CS, CTT, CSP, CSD, and BSD spin-on filter series combine a high-quality filter medium with quick, and clean maintenance to protect hydraulic systems, fuel circuits, and lubrication systems.

Every filtration system faces the same challenge: tTrapping as many contaminants as possible without restricting fluid flow Fai Filtri’s spin-on hydrualic filters meet this need with an inorganic microfiber filter element designed to maximize dirt-holding capacity and minimize initial pressure drop when the filter is clean.

Pressure drop, also called differential pressure, is the difference in pressure between a filter’s inlet and outlet. A clean filter starts with a low pressure drop. The pressure drop rises gradually as the filter captures contaminants, and once it gets too high, the filter needs to be replaced.

How Microfiber Filter Media Works

The microfibers form a dense, uniform structure that traps particles deep within the filter media, not just on the surface, a process known as depth filtration.. The result:

• High dirt-holding capacity, for longer replacement intervals.
• Low initial clean pressure drop, for more efficient flow right from the start.

The microfiber media is designed to hold its shape under high differential pressure and water hammer (sudden pressure spikes), such as those caused by cold starts. Depending on the application, Fai Filtri spin-on filters are also available with cellulose or wire mesh media.

Simple, Clean, and Fast Maintenance

Spin-on filters thread on and off in just a few moments. This means:

• Less downtime
• A clean replacement process, with less risk of fluid spillage and circuit contamination
• Operations that any maintenance technician can perform, without special equipment

Where Fai Filtri Spin-On Filters Are Used

Fai Filtri spin-on filters are used on earthmoving machines, agricultural machines, industrial vehicles, compressors, and hydraulic systems. They are suitable for hydraulic oils, lubricating oils, fuels, glycol water, emulsions, and most synthetic fluids, and they can be equipped with a bypass valve.

The Benefits for Your System

Choosing a Fai Filtri spin-on filter means protecting your system from day one: the microfiber filter media traps particles before they can cause wear extending the service life of pumps, valves, and actuators. Thanks to the filter’s high dirt-holding capacity and quick, easy replacement, filter changes are less frequent and faster, resulting in lower maintenance costs and reduced machine downtime. Performance also remains stable over time, as the differential pressure increases gradually and the system operates smoothly throughout the filter’s entire service life.
