AUX AIR USA, AUX, today announced the launch of its new One-Way Cassette, a compact ductless system built for tight ceiling spaces and clean interior design. The product will be available in the U.S. in July 2026, with orders shipping once placed.
New ductless cassette expands AUX multi-zone lineup with a narrow-joist fit, built-in Wi-Fi control and easier service access
The One-Way Cassette gives contractors and homeowners a new option for rooms where wall-mounted units or ducted systems may not be the best fit. Its compact body fits between 14-inch joist spacing, allowing the unit to sit cleanly in the ceiling without major ductwork.
It was developed for applications such as bedrooms, hallways, home offices, sunrooms and multifamily spaces where traditional ducted systems may be difficult to install. Its low-profile design helps preserve ceiling height and maintain a clean architectural appearance. For contractors, the system offers a clean, serviceable solution for applications where wall-mounted units aren’t ideal and traditional ductwork may add cost or complexity.
The system is available in 9K, 12K and 18K capacities. It includes built-in Wi-Fi control, a washable filter, a high-lift condensate pump with a 57-inch lift and long-range air throw up to 9.8 fee
