PEEK Safety Screens
Lee Products offers a range of flange mount, HI-BAR Safety Screens which includes options made entirely from PEEK (Poly-EtherEtherKetone). The safety screens are designed to protect sensitive components in critical fluids handling applications in the medical, scientific and aerospace industries.
This high performance engineering thermoplastic is said to provide chemical resistance and mechanical properties which result in a lightweight, yet robust, single piece construction safety screen. The safety screens weigh from 0.01g for the smaller FSHF1304 130 flange mount screen and 2.4g for the largest FSHF6700 670 flange mount option. Lee claims this compares to approximately one sixth of the weight of similar screens constructed from stainless steel. They are designed to withstand pressure up to 1000psid without rupture.
With PEEK's ability to maintain its strength and dimensional stability at high temperatures, these screens will also be suitable for the demanding requirements and hostile environments found in aerospace, marine and oil industry applications as well as the medical industry.
The screens are available in six different flange sizes ranging from 3.302 to 17.018mm in diameter and seven different hole sizes ranging from 75 to 500µm. Custom designs are also available for more specific application requirements.
