Ecosoft Big Blue 4.5"x20" In-Line Water Filter Housing

Engineered for high-flow capacity lines, the housing features 1" female threaded ports with a pressure relief valve and handles flow rates up to 83 L/min (5.0 m³/h / 22 gpm). It operates within a working pressure range of 3.5 to 6.0 bar (withstanding pressure surges up to 8.0 bar / 116 psi) across cold water temperatures from +5 to +35 °C (up to +40 °C depending on system conditions). The complete set comes ready for installation with a steel wall-mounting bracket, service spanner wrench, and zinc-plated fixing screws, ensuring straightforward maintenance and tool-assisted cartridge replacement.

Removal Capabilities:

• Sediment & Particle Interception: Captures insoluble mechanical impurities such as rust flakes, sand, silt, and pipe scale when fitted with sediment cartridges.

• Turbidity & Clarity Correction: Eliminates cloudiness, haziness, and suspended matter to deliver clean water throughout the building.

• Chlorine & Taste Improvement: Reduces active chlorine, petrochemical residues, and objectionable odors when equipped with carbon block or granular activated carbon cartridges.

• Plumbing & Appliance Protection: Shields control valves, pumps, boiler heating elements, and membrane modules from abrasive wear and particulate clogging.

Please note: Shut off the water supply and relieve internal pipeline pressure before installing the housing or replacing filter cartridges. To prevent mechanical damage caused by municipal pressure surges or water hammer exceeding 6.0 bar, installing a pressure regulator upstream of the unit is strongly recommended. Use PTFE tape to seal threaded pipe connections, screw the sump by hand until seated, and gently snug it with the included service wrench without applying excessive force. This housing is designed exclusively for cold water treatment—do not use on hot water lines. Inspect all connection points for leaks during the first 2 hours following installation or cartridge service.
