Withair® Package Rooftop Make-Up Air systems offer a flexible way to provide treated air for one- to eight-story buildings. Many options and configurations are available to satisfy a wide number of applications. Fresh outside air is mixed with return air from the occupied space and then filtered, conditioned, and supplied back into the building. Conditioning involves cooling, dehumidifying, or heating the air for optimal space comfort. Rooftop units can serve a single zone, or an entire building filled with many zones. Some units can be designed specifically for make-up air, where only outside air is treated and sent to the space. Inverter compressors, beltless ECM fans, and energy recovery solutions make rooftop systems an easy-to-maintain, energy-efficient choice for conditioning any space. Heat produced by natural gas, electricity, hot water, steam, and heat pumps provides reliable heating for spaces with colder seasons and climates.

Almost invisible, powerful, noiseless and space-saving: this is the Withair® air conditioner without an external unit. No more of the usual bulky, unsightly condensing units that spoil homes. Withair® has developed a high-efficiency solution with a hyper-compact design that minimises aesthetic impact. Just 16 centimetres deep, super simple installation and DC Inverter technology to optimise performance.
