Safety screen filters are a vital component of any hydraulic, fuel, lubrication, or pneumatic system. While filters maintain fluid cleanliness, rogue contamination and debris left in the system during production or generated during operation may still result in sudden failure.
The Lee Company offers a wide variety of standard designs spanning various sizes, materials, retention methods, filtration ratings, and even technology. The Lee Company is the original inventor of drilled filter technology that has provided the industry with a robust, cost-effective, and easily customizable design that withstands burst pressures up to 7500 psid.
Over 50% of safety screen filters manufactured by The Lee Company are unique products designed to meet the requirements of a specific application. As a result, our capabilities far exceed our standard product line, including, for example, drilled hole sizes between 25 micron and 1500 micron, a wide variety of materials, higher burst and collapse pressure ratings, or unique envelopes optimized for high flow capacity, custom mounting, or integrated bypass mechanisms.
Not only has The Lee Company created a market-leading product family of safety screens to provide last chance protection, but we’ve also created a simple system for comparing safety screen filters to one another. Resistance to Blockage (ROB) relates how hole size and the number of holes in a safety screen factor into the overall performance without complex analysis or elaborate testing.
Woven wire mesh safety screens are practical and economical. Flat disc safety screens are used as last chance protection in high-volume production applications. They are constructed of stainless steel woven wire mesh, bonded together using a proprietary process that offers superior integrity and life. They are available in insert, cartridge, and press-in styles. Insert-style screens feature an integral locking end that provides retention. Cartridge screens are designed to be retained by the customer. Press-in style screens contain our unique barbed design, which offers retention in plastic housings and fittings. These are available in a wide range of sizes and micron ratings.
Protect your components with a safety screen drilled from a single bar of metal. The Lee Company was the original inventor of this proprietary process, and its products stand the test of time. The resulting screen is extraordinarily robust, eliminates welds and brazes, and can be produced in custom formats for a wide range of applications.
HI-BAR Safety Screens are rated to withstand burst and collapse pressures up to 7500 psid. They’re available in flange mount, threaded, boss mounted, and fitting adapter installation options. Standard flange mount options include stainless steel, titanium, brass, PEEK, and MP35N, and our standard hole size ranges from 50 to 500 microns.
Lastly, our capabilities far exceed our standard product line, including, for example, drilled hole sizes between 25 micron and 1500 micron, a wide variety of materials, higher burst and collapse pressure ratings, or unique envelopes optimized for high flow capacity, custom mounting, or integrated bypass mechanisms.
Lee Etched Safety Screens feature an economical design, incorporating radial or circular convolutions that significantly increase the contamination carrying capacity of the screen. The result is a robust screen design with an optimum amount of protection in a small package. Etched safety screens are available in six installation methods and manufactured out of 304L CRES and 17-7PH CRES for increased pressure ratings. Hole sizes range from 75 to 500 microns.
The Lee Company’s new Boss Mount Strainers are the latest addition to our line of safety screens, offering coarse level filtration in a compact, low-profile design. Manufactured from 304L stainless steel, the Boss Mount Strainers feature a robust design with a single-piece screen element that can withstand differential pressures up to 500 psid without rupture. In addition, the corrugated screen design provides a maximum open area for increased dirt holding capacity. Lee strainers are available in thread diameters from 0.750 to 1.875 inches with hole sizes of 965 and 1575 micron.
Series 10 and Series 20 Safety Screens are incredibly robust, considering their fine filtration rating. These screens incorporate a rugged, calendered, and sintered 316L stainless steel wire mesh weave for maximum strength. These screens are manufactured using a proprietary process and feature a design that contains radial convolutions that significantly increase the contamination carrying capacity of the screen. The result is a high-strength screen with an optimum amount of protection in a small package. Available in 10 and 20-micron hole sizes with flange diameters from 0.130 to 0.656 of an inch.
