High-Flow Emflon® Filter Element
The High-Flow Emflon filters are designed for bulk nitrogen and clean dry air applications in the LCD and semiconductor industries where flow rates exceed 2,000 Nm3/h / 1,000 SCFM.
- High particle retention
- Exceptionally high flow rates
- Low differential pressure
- 100% integrity tested
- Flow rates up to 6,500 Nm3/h / 3,826 SCFM
Product Benefits
- A single 1,016 mm / 40 in. HFE filter can replace up to (30) standard 254 mm / 10 in. long x 70 mm / 2.75 in. diameter cartridges. This allows for the use of smaller housings which will lower capital investment and offers a smaller installation footprint
- Reduced time for filter replacements
