Summary
Product Identification
The MICRODYN RO XRLE series consists of high rejection, low energy brackish water reverse osmosis (RO) elements. These spiral-wound membranes are designed for water purification applications requiring high rejection combined with reduced energy consumption, operating at low pressure. NSF certification is available upon request.
- Membrane Chemistry: Thin-Film Composite Polyamide

Note on Dimension "C": For Female elements, "C" is the Inner Diameter. For Male elements, "C" is the Outer Diameter. Male elements also have a protruding permeate tube ("D" in diagram) with a dimension of 26.7 mm (1.05 in).
Important Information
Refer to the official MANN+HUMMEL Water & Fluid Solutions guides for detailed start-up, cleaning, and storage procedures to ensure proper operation and prevent membrane damage. Pretreatment is recommended for the removal of free chlorine and other oxidizing agents to prevent damage to membranes.
