Puretec FILTERWALL-IM2-SM Surfmist Aluminium 20 Inch Semi-Recessed In-Wall Filter with plumbed bypass

Unobtrusive whole building water treatment for residential facility mains supplies is achieved by the FilterWall IM2-SM semi-recessed system. Specified for high-flow chlorine and sediment reduction, this model features a Surfmist finished aluminium cover suitable for modern architectural property integrations. The system installs flush within external wall cavities to provide treated water to every outlet without occupying ground space.

Construction utilizes an aluminium housing measuring 680 mm in width and 836 mm in height to accommodate the dual 20-inch cartridges. The internal filtration assembly provides a 5-micron nominal rating for the tiered reduction of sediment and chemical contaminants. The unit has a maximum temperature rating of 52°C and requires an installation depth of 150 mm to house the filtration assembly within the building structural wall.

Fluid velocity paths support a nominal flow rate of 55 L/Min through 20 mm BSP female plumbing connections. The assembly handles operational pressures from 200 to 875 kPa, utilizing lead-free brass for all internal plumbing interfaces to maintain safety standards. This system is a passive unit that functions entirely on mains line pressure without the need for electrical wiring or external power sources.

Monitoring is handled via the integrated pressure limiting valve included in the kit, which also protects the 20-inch cartridges from high supply pressures and spikes. Service access is provided by removing the front cover via lockable latches, with replacement recommended every 6 to 12 months based on usage. Protection from freezing conditions is required for external wall installations. Multiple knockout locations are provided to facilitate various entry configurations.

Features

• Semi-recessed in-wall design provides a structural housing that sits flush with the facility's external profile to save property space while providing whole house treatment.
• Surfmist powder-coated aluminium cover provides a weather-resistant barrier that protects the filtration assembly from outdoor environmental factors.
• Dual 20-inch high-flow filtration configuration provides tiered reduction of sediment and chemicals for the entire property mains water supply.
• Lead-free brass plumbing connections are integrated into the internal assembly to adhere to regulatory safety standards for mains water distribution.
• Integrated pressure limiting valve provides a mechanism for protecting the system from high mains supply pressures and fluctuations during operation.
• Lockable latches on the front panel enable secure access for maintenance while protecting the unit from unauthorized tampering and environmental exposure.
• Low-profile architectural integration allows for high-capacity whole building filtration without the need for a freestanding ground-based enclosure.
