2 Introduction FILTER SIZG DEX CALCULATION CORRECTIVE FACTOR Page Introduction

3 Calculation FILTER SIZG THE CORRECT FILTER SIZG HAVE TO BE BASED ON THE TOTAL PRESSURE DROP DEPENDG BY THE APPLICATION. FOR EXAMPLE, THE MAXIMUM TOTAL PRESSURE DROP ALLOWED BY A NEW AND CLEAN RETURN FILTER HAVE TO BE THE RANGE bar. The pressure drop calculation is performed by adding together the value of the housing with the value of the filter. The pressure drop pc of the housing is proportional to the fluid density (kg/dm ); all the graphs in the catalogue are referred to mineral oil with density of 0.86 kg/dm. The filter pressure drop pe is proportional to its viscosity (mm /s), the corrective factor Y have to be used in case of an oil viscosity different than 0 mm /s (cst). Calculation: pc = 0.0 bar (see graphic below) Δp bar MPT 0 Length * G / Flow rate l/min housings p pressure drop. The curves are plotted using mineral oil with density of 0.86 kg/dm in compliance with ISO 968. p varies proportionally with density. Sizing data for single filter, head at top pc = housing pressure drop [bar] pe = pressure drop [bar] Y = Corrective factor Y (see correspondent table), depending on the filter type, on the filter size, on the filter length and on the filter media Q = flow rate (l/min) V reference oil viscosity = 0 mm /s (cst) V = operating oil viscosity in mm /s (cst) pressure drop calculation with an oil viscosity different than 0 mm /s (cst) pe = Y : 000 x Q x (V:V) p Tot. = pc + pe Verification formula p Tot. p max allowed pe = (.00 : 000) x 0 x (6 : 0) = 0.7 bar H Series Nominal filtration Type A0 A06 A0 A6 A P0 P M60 M90 Return filters MF MF 00 MFX 00 MF 00 MFX Maximum total pressure drop ( p max) allowed by a new and clean filter Application Suction filters Return filters Low & Medium Pressure filters High Pressure filters Stainless Steel filters Range (bar) return lines lubrication lines offline in power systems offline in test benches overboost p Tot. = = 0. bar The selection is correct because the total pressure drop value is inside the admissible range for top tank return filters. In case the allowed max total pressure drop is not verified, it is necessary to repeat the calculation changing the filter length/size. Generic filter calculation example Application data: Tank top return filter Pressure Pmax = 0 bar Flow rate Q = 0 l/min Viscosity V = 6 mm /s (cst) Oil density = 0.86 kg/dm Required filtration efficiency = μm with absolute filtration With bypass valve and G / inlet connection Introduction

8 FHA 0 Description GENERAL FORMATION Technical data High Pressure fi lters Inline Maximum working pressure up to 6 MPa (60 bar) Flow rate up to 0 l/min FHA is a range of high pressure filter for protection of sensitive components in high pressure hydraulic systems in the mobile machines. They are directly connected to the lines of the system through the hydraulic fi ttings. Available features: Female threaded connections up to /, for a maximum flow rate of 0 l/min Fine fi ltration rating, to get a good cleanliness level into the system Bypass valve, to relieve excessive pressure drop across the fi lter media Check valve, to protect the system against reverse fl ow Reverse flow valve, to allow bidirectional flow through the filter housing. The back fl ow is not fi ltered Low collapse filter N, for use with filters provided with bypass valve Low collapse fi lter with external support R, for fi lter protection against the back pressure caused by the check valve or the reverse fl ow in fi lters provided with the bypass valve High collapse fi lter with external support S, for fi lter protection against the back pressure caused by the check valve or the reverse fl ow in fi lters not provided with the bypass valve Visual, electrical and electronic differential clogging indicators Common applications: Delivery lines, in any heavy duty industrial equipment or mobile machines housing materials Head: Steel (chemical heat treatment) Housing: Steel (chemical heat treatment) Bypass valve: Steel Pressure Test pressure: 8 MPa (80 bar) Burst pressure: 68 MPa (680 bar) Pulse pressure fatigue test: cycles with pressure from 0 to 6 MPa (60 bar) Bypass valve Opening pressure 600 kpa (6 bar) ±0% Other opening pressures on request. p type Microfi bre fi lter s series NR: 0 bar Microfi bre fi lter s series S: 0 bar Wire mesh fi lter s series N: 0 bar Fluid fl ow through the fi lter from to Seals Standard NBR series A Optional FPM series V Temperature From C to +0 C Connections Inline Inlet/Outlet Note FHA fi lters are provided for vertical mounting Weights [kg] and volumes [dm ] series FHA 0 Length Weights [kg] Length Volumes [dm ] High Pressure fi lters 00
