Fujitsu AIRSTAGE J-IIS Series compact, lightweight air-conditioning system

The AIRSTAGE J-IIS Series air-conditioning system from Fujitsu General is a compact, lightweight unit suitable for a range of applications from small office buildings and stores to large houses.

At 998 mm tall and 87 kg, the model is 25% shorter and weighs 26% less than conventional 6 HP comparable outdoor units, making it suitable for installation under windows and in tight spaces.

The sound level has been lowered to 54 dB(A) for the 6 HP model when cooling, by using DC twin rotary compressor, inverter technology and advanced airflow structure design, including a large propeller fan and angle optimisation. A miniaturised, low-noise, high-efficiency, multistage DC fan motor is mounted. Heat exchange performance has been improved by mounting of a 3-row large heat exchanger. The smooth airflow grille has been aerodynamically designed for good efficiency with little blow loss.

Efficiency has been improved by mounting of a new active filter module, while a compact and high-performance DC twin rotary compressor offers good performance from low to medium at normal operation. Advanced refrigerant control technology has enabled a total refrigerant piping length of 80 m and the non-stop oil recovery operation maintains a comfortable room condition because the product continues to operate.
