Cartridge screens block rogue
contaminants
In most critical fluid control components such as those found in high pressure hydraulic applications, filter systems play a crucial role in protecting against rogue contamination
However effective the main 'in-line' filters are in these components, there is always the possibility that small particles or contaminants can pass through the main filters and so increase the potential for damage With these risks in mind Lee Products offers a range of Industrial Microhydraulic (IMH) cartridge screens which provide a low-cost, yet effective 'last-chance' filtration barrier

A miniature, cartridge style shuttle valve which is designed to install easily into a drilled hole, is the latest addition to the Lee Products range of miniature components
Rugged safety screens handle double the pressure
Lee Products introduces a range of high pressure flange mount etched safety screens with burst / collapse pressures more than double that of existing stainless steel 304L type safety screens
Miniature relief valve ensures zero leakage
The new Lee 281 miniature relief valve is ideally suited for thermal relief and low flow hydraulic pressure relief applications, where zero leakage is essential
The latest additions to the range are new high pressure cartridge screens, which are rated for a minimum burst pressure of 35 MPa (5,000 psi).
These screens are constructed of stainless steel woven wire mesh and bonded together using a proprietary process that ensures superior integrity and long-life.
All IMH high pressure screens use multiple screen layers and support disks to provide additional strength and integrity for applications where higher pressures could cause a single layer screen to rupture due to the effects of clogging, possibly with catastrophic consequences.
For this reason Lee high pressure screens incorporate a unique, multi-layer which ensures a gradual reduction in flow performance, as opposed to a rupture which could result in a concentration of dirt flushing downstream, possibly disabling sensitive downstream components.
IMH Cartridge Style Screens are designed to slip into a drilled hole and be retained by a secondary means.
The available diameters of 5.5, 8, 10 and 12mm have been selected so that other IMH components can be used to retain the screen.
For example, the 8mm cartridge style screen can be retained using a Lee IMH 855 Series Reverse check valve.
Whilst not intended to serve as system filters these cartridge screens are an effective, final filtration barrier to protect fuel, hydraulic, lubrication and other similar systems. Request a free brochure from Lee Products ...
