|Standard Installation Configurations||Etched Screens||Hi-Bar Drilled Screens|
This is perhaps the most common installation technique as it is simple and economical.
A common installation technique that permits removal. Some form of anti-rotation locking is recommended.
Utilizing the proven Lee Insert Principle, this technique is ideal for simple installation directly into a fluid passageway.
|L - 4
Featuring three locking fingers that are expanded outward locking the screen in a fluid passageway, the L- 4 technique permits easy removal for inspection or cleaning. Ideal for bidirectional flow.
An inexpensive mounting technique suitable for unidirectional flow. The spring O.D. is slightly larger than the I.D. of the mounting hole. A special tool is used to twist the spring into the hole.
Easily removable, the "TWIS" style of installation is readily twisted in or out of the bore for inspection or cleaning. Unidirectional flow.
A convenient mounting technique that permits easy removal for cleaning or inspection.
|HI-BAR SCREENS IN ADAPTERS
Often used as inlet screens to actuators, optimizing space and weight. Available in AS-Straight Thread and Ring Locked style adapters complete from The Lee Company.
