Suction filters

THE IMPORTANCE OF AN EFFICIENT FILTRATION The main cause of anomalies in hydraulic systems has to be attributed to the presence of contaminants in the fluid. The nature of the contaminant may be: gaseous, namely air mixed with the fluid; fluid, it depends on water penetrating the fluid; solid, therefore particles of various origins and dimensions. Customers who operate equipments are always focused on obtaining the best possible performance, lower energy consumptions and greater respect for the environment. These characteristics can be attained by using top quality components in the hydraulic...

TECHNICAL CHARACTERISTICS The HF 410 and HF 412 suction line filters series are directly connected to the circuit's suction line and protect the system's components against contaminant particles. The filters can be supplied with by-pass valve set at 2.9 psi (0,2 bar). In the 10-20-30 dimensions, the HF 412 serie is made with an outside diameter smaller than the relative HF 410 versions. l Flow up to 80 US gpm (300 l/min) l By-pass valve l "FS" version with oversized filtering surface OPERATING TEMPERATURE Reinforced nylon Zinc plated steel Inner tube Filter media Zinc plated steel Steel wire...

ASSEMBLY AND FILTER SUBSTITUTION INSTRUCTIONS ASSEMBLY FILTER SUBSTITUTION Once you have checked the integrity of the filter inside its package, proceed as follows: Once the working hour limit indicated in the maintenance instructions of the system has been reached, or when the suction line's clogging indicators reach the maximum depression's limit established, the filter needs to be substituted taking care of the eventual oil leaks due to this operation. So it is advisable to hold containers for the collection. Proceed as follows: Screw the filter on the male junction until getting the attainment...
