Efficiency and reliability are key factors when choosing an air conditioning system. Our easy-to-install Free Joint Multi (FJM) unit delivers both. Its compact design means that it can be easily incorporated into a variety of professional and residential situations, with the flexibility to support up to 5 indoor units. Furthermore, its double layer sound insulation system minimises noise, making it more discreet despite its high-quality performance. In addition, the one button auto-addressing feature simplifies installation, which results in minimal disruption to the day-to-day activities of busy companies.

Wide Operation Range Of Outdoor Temperature

No matter how extreme the temperature, our FJM air conditioning unit will handle the situation. It is able to cool in heats of up to 50°C and provide warmth in -20°C, eliminating the need for any additional units to cope in times of adverse weather. Its smart inverter system delivers the required temperature quickly right from start up, and continuously performs fine-tune adjustments to ensure a constant and comfortable environment.

BLDC (Twin Rotary) Compressor


A key contributor to the FJM’s efficiency is its BLDC (Twin Rotary) Compressor, which is featured on all outdoor models. Its twin eccentric cams and two balance weights result in extremely low levels of vibration, contributing to a much quieter all-round performance. Attention to the quality of moving parts such as robust bearings, as well as premium matching rollers and vanes produce a high degree of stability and durability.

Reduced Vibration and Noise


All new FMJ outdoor models incorporate the TBR Sine-Wave Compressor in addition to the twin BLDC compressor. This serves to reduce torque variation by 70 per cent and vibration by 80 per cent compared to a regular single compressor. As a result, stress on the motor is kept to a minimum, and the lifespan of the air conditioning unit is extended. A further benefit is a significant reduction in noise, leading to a more comfortable and productive working environment.
