Davey Microlene W20J25MM 20" Jumbo Filter Housing with Pressure Relief and Spanner

Large scale whole-of-house water quality management for residences is facilitated by the Davey Microlene W20J25MM 20 inch jumbo single housing. This unit is for applications where maximum dirt-loading capacity and high flow rates are required. It is for installation in residential utility loops, providing a foundation for large-scale filtration using 20 inch jumbo cartridges. The assembly uses 25mm plumbing ports to accommodate the flow requirements of multi-bathroom homes.

Constructed from reinforced polypropylene, the housing is durable and designed for long-term service in residential and light commercial water systems. It utilizes 20 inch jumbo cartridges with an 114mm outer diameter, providing high surface area for sediment and chemical reduction media. The assembly features a built-in pressure relief valve on the cap to bleed off hydraulic pressure during manual cartridge changes. Measuring 620mm in height and 185mm in width, the unit provides volume for peak usage.

The system operates using 25mm 1 inch BSP female connections and is rated for a maximum system pressure of 880 kPa. As a passive filtration vessel, it relies on line pressure to move water through the large media bed of the jumbo cartridge for contaminant removal. Its large internal volume accommodates high-capacity cartridges for whole-of-house filtration applications. It is rated for water temperatures up to 40 degrees Celsius and maintains structural stability in ambient heat.

Operational safety is provided by WaterMark certification and compliance with WMTS-103 licensing for residential treatment appliances. The kit includes a dedicated housing spanner and a mounting bracket with all necessary hardware for a secure installation. It is for installation on biologically safe water sources and provides the containment required for whole-of-house filtration media. This 20 inch jumbo housing offers a platform for large residences.
