FSD Medium Pressure Filter Assembly

Medium pressure FSD series complete filter assemblies from FAI Filtri in Italy.

The FSD range is capable of 35 Bar pressure, making them a very handy item where there is higher than normal return pressure, pressure spikes or heavier grade oils.

They can also be used in place of a pressure filter in lower pressure applications <500psi.

Features:

• Cast aluminium head
• Cast aluminium flange
• 1” BSPP ports
• Built-in clogging indicator
• 6, 10, and 25 absolute micron filters made of bx ≥ 200 reinforced, inorganic fibres with polyester protection
• 3 Bar bypass valve
• Flow rates up to 95 litres per minute

Pressure Drop

Curved are calculated in accordance with ISO 3968 and are valid for clean filtering elements.

DP changes along with the density in presence of an eddy flow, and along with the dynamic viscosity in presence of a laminar flux. Curves are valid for mineral oils with a density of 0.86 kg/dm3 and a dynamic viscosity of 30mm2/sec (Centistokes).

When choosing the filtering medium, consider the pressure losses deriving from the flow rate:

• Between 0.05 & 0.1 bar for suction line
• Up to 0.3 - 0.5 bar for filters fitted on return line

(The total pressure drop is to be calculated by adding up the spin-on filter pressure drop).

Many years of in-field experience have shown the necessity of more and more efficient controls on the contamination level of hydraulic fluids and fuels.

With this goal uppermost in its mind, and thanks to sophisticated design patterns and the use of cutting edge materials and technologies, FAI FILTRI has engineered a complete series of spin-on filters, in different models and sizes, designed to meet a wide array of filtration and operating requirements, in order to allow a more effective control of contamination levels in hydraulic, lubricating, engine circuits, etc.

FSD complete filters, engineered to support medium pressure values up to a maximum pressure of 35 bar, provide a valid solution for filtration problems, granting their best performances when fitted into hydraulic drives, in presence of supercharged hydrostatic drives, earthworks machines, compressors, converters, hydraulic systems return or exhaust lines.

The main characteristics of these expendable elements the possibility for any clogged filter to be easily replaced by a quick and clean procedure, condition that has to be considered of great importance in working contexts where highly deteriorated environmental conditions usually occur.

They can support flow rates up to 95 litres per minute. FAI FILTRI spin-on cartridges, equipped with new generation “A” filtering media, can specifically grant high standards of performance even in the hardest conditions. “A” type elements with absolute filtration power of 3, 6, 10, 25 micron (bx 200), are formed by inorganic impregnated and resin bonded inert micro-fibres, supported upstream and downstream.

The result is a very compact filtering core which ensures the resistance of the media itself to deformation, distortion and strain, preventing any contaminants to get released, thus improving filtering performances and allowing contaminants to accumulate efficiently, also in the event of phenomena such as high differential pressure and water hammering derived from cold starts and discharge flow rates.

The above mentioned features make the FAI FILTRI spin-on filters consistent with the use of hydraulic, lubricating oils, fuels, glycol water, emulsions and most synthetic fluids.
