Energy saving, dedicated to fan and pump for HVAC (*Heating, Ventilating and Air Conditioning)


Advanced harmonic suppression, power factor improvement.

With Toshiba unique reactor-less technology, the VF-FS1 suppresses harmonics, particularly the 5th and the 7th harmonic current which especially has harmful effects on power supply. As a result, the power factor of all the VF-FS1 models improved to more than 94%.

Dedicated functions for air-conditioning equipment.

The VF-FS1 is designed specifically for pump and fan applications in the HVAC industory. The special functions include, Local/Remote mode, Fire control mode, PID control mode, etc .

Long operating life, easy maintenance.

Film capacitors are used in main circuit, which are expected to be able to operate for 15 years.
