The Caroma Aire Connector Plastic Dual Flush Cistern (234040W) is an economy-grade, integrated plastic cistern and toilet seat combination purpose-built for connector-style toilet suite installations. Featuring a flush-fitting connection plate that conceals the flush pipe and water supply connection, the Aire delivers a clean, uncluttered finish suitable for residential new builds, rental properties, social housing, and commercial bathroom fitouts where reliable performance and cost-efficiency are the primary specification criteria.

Supplied complete with a Tasman wide seat and link, this cistern is ready to install straight from the box with no additional seat purchase required.

Key Features

Flush-fitting connection plate — conceals flush pipe and water connection for a neat, finished appearance
Low profile lid design — with chrome bezel and dual flush buttons
Integrated plastic construction — lightweight, durable and corrosion-resistant
Supplied with Tasman wide seat and link — complete installation package, no additional seat required
Bottom inlet configuration — standard installation for low-level cistern setups
Adjustable flush volume — factory set to 4.5/3L, convertible to 6/3L or 9/4.5L by removing a spacer
WELS 4 Star rated at 4.5/3L — when installed with a compatible 4.5/3L Connector Smartflush pan
Easy to follow installation instructions — included in the box

Flush Volume Configuration

The Aire cistern is supplied factory-configured to 4.5/3L dual flush and can be adjusted on-site to 6/3L or 9/4.5L by simply removing the internal spacer — no tools or additional parts required. This flexibility makes it suitable for installation across varying water authority requirements and project specifications without the need to stock multiple cistern variants.

Important: To achieve the WELS 4 Star rating, this cistern must be installed with a compatible 4.5/3L Connector Smartflush pan. Installation with a non-Smartflush pan will result in a lower WELS star rating.

Suitable Applications

The Aire Connector Cistern is ideally specified for residential new builds and renovations, investment and rental property bathrooms, social and community housing projects, commercial amenities requiring a cost-effective and compliant dual flush solution, and direct replacement of existing connector-style plastic cisterns in comparable configurations.
