Screens boosts system safety
Hi-Bar safety screens complement the role of filters by providing optimum security and protection for individual high-value components in aerospace, defence and other critical applications.
Protecting high value components from random surges of contaminants, such as those used in hydraulic, fuel and lubrication systems in aerospace applications, is an important safety issue Typically, wire mesh and sintered screen filters are the inline devices which offer protection by cleansing whole systems

The new Lee new sub-miniature latching solenoid valve is specifically designed for applications that demand ultra-low power, low heat and small size.
Low weight compact lubrication and scavenge pumps
Lee Products is now able to offer custom designed lubrication and scavenge pumps for applications which require low weight within a compact envelope.
However, a highly resilient and more targeted alternative is available from Lee Products, the pioneer of the design and manufacture of miniature precision fluid control components.
The Hi-Bar series of safety screens from Lee Products are designed to complement the role of filters by providing optimum security and protection for individual high-value components in aerospace, defence and other critical applications.
These one-piece barriers are available in steel or aluminium and feature laser-drilled holes, a process which results in extremely accurate and evenly spaced holes of between 75 and 400 microns diameter and from 35 up to 37,000 holes per metal screen.
Fully clogged Hi-Bar screens can withstand pressures up to 518bar without collapse and allow bidirectional oil flow.
One recent example of the successful application of these safety screens is Parker Hydraulics use of Lee's safety screen in its revamped PM125 hydraulic pump which is incorporated into the MoD's fleet of armoured recovery vehicles, based on the Chieftan tank design.
Hi-Bar safety screens are available in a number of variations including flange and boss mounted options offering benefits such as rugged, high strength performance, no burst or collapse at 7500lb/in2(d) fully clogged and high contamination carrying capacity for maximum protection.
