Types of Filters available are listed below;
Low pressure filter
Low pressure filters are the most common type of filter in hydraulic circuits. They are often used as return line filters in applications with working pressures up to 150 psi, depending on the model selected.
FIK in tank Assemblies
The FIK in tank return line filters are economical and space saving with simple screw-on covers, ideal for low pressure, in tank applications. This is a heavy duty filter, with the die cast aluminium head and steel canister. The head (and inlet) sit above the tank, with the housing (and outlet) in the tank.
Medium pressure filters
The HMK series of spin-on hydraulic filters feature high performance, high flow and medium pressure. They are designed for return line and side loop systems. Applications include fluid conditioning, process systems, lube oil systems, power transmission, case drains, hydrostatic charge pumps and cooling systems. The element has a heavy duty steel body with die-cast top plate and the head is made from die-cast aluminium.
High pressure hydraulic assemblies
The following are high pressure hydraulic assemblies used on in-plant and mobile hydraulic systems. Applications include hydrostatic transmissions and high pressure circuit systems. Made from ductile iron for strength and durability, they are available with a reverse flow check valve which allows bi-directional flow through the filter-head.
