Description
The PhotoKleen™ EZD-3 filter is designed for extremely small resist pump installations. It is specifically designed for small-volume dispense systems, which have the smallest footprint. The PhotoKleen EZD-3 filter unit consists of a quick-disconnect head manifold and a High Density Polyethylene (HDPE) capsule. This configuration allows for safe, quick, and easy filter change outs. Three filter media – PTFE, HDPE and nylon 6,6 – are available. The naturally hydrophilic nylon 6,6 membrane allows for spontaneous wettability. This minimizes photochemical waste by providing quick start up and minimized bubble generation.
- Capsule-style filter assembly
- Top in / top out flow direction, with inlet flow stream down to the bottom
- Minimized hold-up volume (40 mL)
- Quick filter replacement (one step)
- Optimized for 60 mm-width resist pump for reduced dispense system
- Minimized dead space
- Reduces chemical waste during filter startup and change out

Caution: For optimal filtration performance, it is recommended to replace your filters at-least once a year. Annual replacements will reduce the potential of any leakages that may result due to prolonged chemical exposure. Pall warrants its filters for a period of 1 year from the date of shipment.
