Davey Microlene W20J40MM 20" Jumbo Filter Housing with Pressure Relief and Spanner

Wide-bore port optimization for high volume whole-of-house systems is provided by the Davey Microlene W20J40MM 20 inch jumbo filter housing. This unit is for medium to large homes and commercial facilities where high flow demands require minimal hydraulic resistance. It is for installation in main water lines, providing a high capacity container for jumbo filtration cartridges. The 40mm connections integrate with larger plumbing infrastructure for consistent delivery to outlets.

Constructed from reinforced polypropylene, the housing is durable and resistant to the structural loads of large-scale residential water systems. It utilizes 20 inch jumbo cartridges with an outer diameter of 114mm, providing maximum surface area for sediment and chemical reduction passes. The cap features a built-in pressure relief valve that allows for manual pressure release during maintenance intervals. It measures 620mm in height and 185mm in width, accommodating large filtration media.

The housing operates with 40mm 1-1/2 inch BSP female connections and is rated for a maximum pressure of 880 kPa. As a passive vessel, it achieves its filtration goals by relying on system pressure to move water through the selected cartridge media while providing a low pressure drop. Its large internal volume accommodates high-capacity cartridges for whole-of-house filtration applications. It is rated for water temperatures from 0 to 40 degrees Celsius and ambient heat up to 50 degrees Celsius.

Operational safety is provided by WaterMark certification and compliance with WMTS-103 licensing for water treatment equipment. The kit is supplied with a dedicated jumbo housing spanner and a mounting bracket with fixings to provide a secure installation. It provides a reliable solution for whole-of-house filtration on biologically safe water sources, delivering capacity particulate and chemical reduction. This 40mm jumbo housing offers a robust platform for large sites.
