Filter disc FSSA series

This etched last chance filter features a seamless, one-piece screen element formed with pleats to greatly increase contamination carrying capacity. The result is a robust screen design with an optimum amount of protection in a small package. It is offered with several standard hole size options ranging from 75 to 500 microns. This version incorporates a simple flange mount with a retention spring, a combination which provides for an inexpensive mounting technique suitable for unidirectional flow. The spring OD is slightly larger than the ID of the mounting hole and a special tool is used to twist the spring into the hole. Once the tool is removed, the spring holds the screen in place. - Mounting Configuration: Spring Retained - Lohm Rate: 250 Lohms - Micron Rating: 75 to 500 microns - Part Diameter: 0.170 inches - Screenable Passageway Diameter: 0.07 inches Materials - Spring: 302 CRES, ASTM A 313 - Screen: 304L CRES, ASTM A 666 - Base Washer: 304L CRES, ASTM A 666 - Braze: Silver Alloy, AMS 4774 - Finish: All CRES Parts Passivated Part Numbers & Specifications - FSSA1700030A: 250 Lohms, 450 psid collapse pressure, 75 μm hole size - FSSA1700040A: 250 Lohms, 750 psid collapse pressure, 100 μm hole size - FSSA1700060A: 250 Lohms, 1100 psid collapse pressure, 150 μm hole size - FSSA1700080A: 250 Lohms, 3000 psid collapse pressure, 200 μm hole size - FSSA1700100A: 250 Lohms, 2500 psid collapse pressure, 250 μm hole size - FSSA1700150A: 250 Lohms, 2200 psid collapse pressure, 380 μm hole size - FSSA1700200A: 250 Lohms, 2200 psid collapse pressure, 500 μm hole size Installation & Manufacturing Tools - Installation / Extraction Tool Set: CUTA1700128C Replacement Parts & Accessories - Installation / Extraction Tool Set: CUTA1700128C Flow Curve - Flow performance on water at 80°F.
