The WPSX Capsule Filter is a general service, single-layer Polyethersulfone (PES) membrane filter engineered for efficient particulate reduction in a wide range of water filtration applications. WPSX delivers consistent performance, high flow rates, and excellent throughput in cost-sensitive environments. Though not validated for microbial retention, this filter excels at removing high contaminant loads and extending the life of downstream filtration stages.

Key Features:

• Single-layer hydrophilic PES membrane
• Economical, general-use design with high capacity and flow
• Removes large particulate loads in non-critical applications
• Low extractables and high chemical compatibility
• Scalable from lab to production

Performance Parameters:

• Max Operating Temp: 110 °F at 30 psid (43 °C at 2.07 bard)
• Forward Differential Pressure: 80 psid at 68 °F (5.52 bard)
• Reverse Differential Pressure: 50 psid at 68 °F (3.45 bard)
• Recommended Changeout Pressure: 35 psid (2.41 bard)
