AUX AIR USA, a subsidiary of global HVAC leader AUX, launched 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.
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 feet. For contractors, the unit includes a slide-out PCB control box that can be serviced without removing the unit from the ceiling, plus an integrated circuit breaker that cuts power during maintenance.
