AUX AIR USA, a subsidiary of AUX, has launched its new One-Way Cassette, a compact ductless system designed 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.
The One-Way Cassette is intended for rooms where wall-mounted units or ducted systems may not be the best fit. Its compact body fits between 14-inch joist spacing (approx. 356 mm), allowing the unit to sit in the ceiling without major ductwork.
The system was developed for bedrooms, hallways, home offices, sunrooms and multifamily spaces where traditional ducted systems may be difficult to install. Its low-profile design is intended to preserve ceiling height and maintain a clean architectural appearance.
The One-Way Cassette 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 (approx. 1.45 m) and long-range air throw up to 9.8 feet (approx. 3 m). For service access, 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.
“The One-Way Cassette is a smart addition to our multi-zone lineup because it solves a real installation problem,” said John McGaughey, Vice President of Sales at AUX AIR USA. “Contractors need equipment that fits the space, looks good when the job is done and can be serviced without extra hassle. This product gives them that flexibility while giving homeowners quiet, efficient comfort in a clean ceiling-mounted design.”
