New ductless cassette expands AUX multi-zone lineup with a narrow-joist fit, built-in Wi-Fi control and easier service access
AUX AIR USA, a subsidiary of global HVAC leader 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.
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.
“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.”
The One-Way Cassette is part of AUX AIR USA’s growing residential comfort portfolio and reflects the company’s continued investment in the North American residential HVAC market. By adding a ceiling-mounted cassette to its multi-zone lineup, AUX is giving distributors and contractors another option for modern homes, renovations and spaces with limited ceiling clearance.
