Compact Manual SF₆ Recovery System for 10–35 kV Medium-Voltage Switchgear
The KSLF-3Y/T Portable SF₆ Gas Recovery Unit is a compact and lightweight manual SF₆ recovery system designed for on-site SF₆ recovery from 10–35 kV medium-voltage switchgear.
Equipped with a built-in air-cooled SF₆ compressor, the unit supports both gas-phase and liquid-phase SF₆ recovery. Recovered SF₆ can be transferred directly to a connected gas cylinder for storage and subsequent reuse or treatment.
With a weight of less than 25 kg excluding the gas cylinder and compact dimensions of approximately 500 × 300 × 400 mm, the KSLF-3Y/T is designed for convenient transportation and field operation.
The portable SF₆ recovery unit is particularly suitable for field service teams, medium-voltage switchgear maintenance, and occasional SF₆ recovery operations where portability and easy deployment are important.
With a total weight of less than 25 kg excluding the gas cylinder, the KSLF-3Y/T can be easily transported between service locations.
The system supports both gas-phase and liquid-phase SF₆ recovery, providing flexibility for different switchgear service conditions.
The unit is specifically designed for SF₆ recovery applications involving 10–35 kV medium-voltage switchgear.
The integrated SF₆ compressor provides a displacement of 2.8 m³/h and uses air cooling for convenient field operation.
Recovered SF₆ can be transferred directly into a connected storage cylinder through the gas cylinder connection system.
The KSLF-3Y/T operates on a 220 V power supply, making it suitable for service environments with standard electrical power.
The compact aluminum enclosure provides protection during transportation while making the unit convenient for on-site SF₆ recovery and maintenance.
The KSLF-3Y/T portable SF₆ recovery unit is suitable for a variety of field service and maintenance applications.
Designed for recovering SF₆ gas from medium-voltage switchgear during maintenance, inspection, repair, or equipment replacement.
Its compact size and low weight make the unit suitable for field technicians who need to transport SF₆ recovery equipment between different service locations.
The unit can be used to recover SF₆ before opening or servicing SF₆-insulated electrical equipment.
Recovered SF₆ can be transferred directly into a connected gas cylinder for storage.
The KSLF-3Y/T is particularly suitable for occasional or mobile SF₆ recovery operations rather than continuous high-volume workshop recovery.

For field service applications, a large SF₆ recovery system is not always necessary. The KSLF-3Y/T Portable SF₆ Gas Recovery Unit provides a more compact solution for maintenance teams working with medium-voltage switchgear.
Its lightweight design, 220 V power supply, built-in compressor, and gas/liquid recovery capability make it suitable for applications where mobility, quick deployment, and convenient transportation are key requirements.
Compared with larger workshop-oriented SF₆ recovery systems, the KSLF-3Y/T is intended primarily for on-site and occasional recovery operations.
SF₆-insulated switchgear requires proper gas handling during maintenance and servicing. Recovering SF₆ before opening the equipment helps prevent unnecessary gas release and allows the recovered gas to be transferred to a storage cylinder.
The KSLF-3Y/T provides a portable solution for these operations, particularly for 10–35 kV medium-voltage switchgear.
For larger GIS installations, higher recovery volumes, or applications requiring automatic recovery, vacuuming, filling, and purification functions, KSTONE can provide larger customized SF₆ service and recovery systems.
The KSLF-3Y/T is a compact manual SF₆ gas recovery unit designed for on-site recovery of SF₆ from 10–35 kV medium-voltage switchgear. It supports both gas-phase and liquid-phase recovery.
