Rugged safety screens handle double the pressure

A range of high-pressure flange mount etched safety screens (Figure 1) with burst/collapse pressures which are said to be on average more than double that of the existing stainless steel 304L type safety screens, have been introduced by miniature component specialists Lee Products.

Thanks to their rugged construction, using 17-7PH CRES material, these screens provide burst/collapse pressures (depending on the hole size) from 1,250/100 psid for the 656 flange mount option, up to 7,000/4,550 psid for the 130 flange mount option. In addition to taking advantage of higher strength material properties, the screens are designed to excel in open area by utilizing a pleated screen bend feature which maximises their open area, or dirt holding capacity.

The screens which are available in 28 standard versions, claim outstanding flexibility for applications such as aircraft hydraulic systems and engine fuel systems and are completely interchangeable with LEE’s existing etched, flange mount safety screens. They can be supplied in seven different flange sizes ranging from 0.130 to 0.656 in. in diameter. In addition, standard screen hole sizes include 0.004, 0.006, 0.008 and 0.015 in., nominal weights are from 0.05 to 3.1 g.
