FV9C 9m3/h Gas Recovery

FV9C is a PLC-controlled automatic equipment for filtration and recovery of SF6 gas from gas-insulated electrical circuit breakers. The gas is filtered and pumped, from a gas-filled object, to a standard gas cylinder which is connected to the equipment. Evacuation of gas to 1 mbar. The equipment is also used for refilling filtered/new gas via a built-in gas regulator.

Via a 7" HMI display, the operator can easily choose between a number of pre-programmed programs for simple gas handling. No manual valves or push buttons need to be adjusted during normal operation, which makes handling easy for the operator.

The equipment is built on a painted steel chassis with fork lift pockets with connection of hoses easily accessible at the front and connection of electric cable at the back. It is designed to be as ergonomic as possible for the operator.

SF6 evacuation
Hose is connected between FV9C equipment and gas-filled object via the supplied connector. Evacuation of SF6 takes place using an oil-free compressor with a maximum capacity of 9 m³/h and a dry vacuum pump, down to 1 mbar. Storage of evacuated gas takes place in the customer's gas cylinder with a storage pressure of a maximum of 51 bar (abs).

Air evacuation
Hose intended for air is connected to the object via the supplied connector. Air vacuum pump with a capacity of 16 m³/h is used to empty objects of air, down to a final vacuum of 1 mbar.

SF6 filling
Filling is done most easily with self-pressure from a gas bottle, but the FV9C is also equipped with a built-in SF6 gas regulator that can be used. No hoses then need to be switched for filling. If pressure equilibrium between object and bottle occurs, the FV9C can be used to pump gas from bottle to object. The gas cylinder can then be emptied down to 1 mbar.



Product Description

Equipment FV9C for gas handling and gas recovery of SF6 gas is an automatic gas handling equipment.

FV9C is designed with approved and well-tested components for SF6 gas. Leak-free couplings and components in FV9C for gas handling and gas recovery of SF6 are used to prevent emissions of SF6 gas. The machine is delivered tested, leak tested and CE approved with user-friendly manual / documentation for safe handling.

Standard equipment

FV9C gas equipment is supplied complete with the necessary equipment for use. All accessories that come with the FV9C can be stored in a storage box in the chassis during transport:

  • Hose kit for SF6
  • Hose kit for air
  • Connection piece
  • Manual


The frame is a welded and painted steel chassis (RAL 5003, Dark blue) where the machine's components are mounted. Cover plates are fitted around the compressor to protect the equipment and facilitate air cooling. The chassis is designed with truck pockets for transport.


Pre-programmed programs for evacuation, filling, pressure equalization and filter regeneration. PLC, controlled valves and pressure sensors in the system monitor and control the program operation. When the selected program has finished, the machine stops automatically or is stopped if necessary by the operator.

Operating panel

User-friendly 7″ HMI panel for automatic operation and monitoring. Flow chart for better understanding of the process and emergency stop / reset button on the front of the equipment. Pressure gauges for reading pressure for different parts of the flow. Vacuum value during the process is shown in the HMI display.

Oil-free SF6 compressor and SF6 vacuum pump

Oil-free compressor and vacuum pump are used to pump SF6 gas. 1 pcs compressor with a capacity of 9 m³/h and a maximum pressure of 51 bar (abs). If maximum pressure is reached, the machine switches off automatically. Dry vacuum pump with capacity of 6.8 m³/h and 0.02 mbar final vacuum.


Self-developed SF6 filters that filter out particles, clean used SF6 gas from chemical residues and remove moisture from the gas. Filtration of particles down to 1 µm via stainless filter cartridge that can be reused. Chemical filters are dried out and regenerated using a mounted heating element in combination with a vacuum pump.

Air vacuum pump

Oil-lubricated vacuum pump intended for evacuation of air. Capacity of 16 m³/h and 0.5 mbar final vacuum. The pump is firmly mounted in the chassis when in use. Used e.g. after service when objects are filled with air and must be evacuated before refilling with SF6 gas.

Connection piece

Connection piece for connection to electrical equipment. In standard version with ABB/ASEA connection. Connection for extra pressure gauge. Connection for external gas bottle, which allows the connector to be used for re-filling of gas.


Supplied with complete SF6 hose kit with DN8/DN20 fittings. Separate air hose with DN20 coupling, for connection between coupling piece and air vacuum pump. All hoses are reinforced with stainless steel wire braid with an inner hose made of PTFE.


  • SF6 adapter kit - Adaptation of filling equipment with standard connections for switchgear and breakers (DN6, DN7, DN8, DN20, Hansen, Magrini, Malmkvist (Malmquist), Westinghouse etc.)
  • Material selection – Most components / fittings are available in several materials (eg stainless steel, brass, aluminum).
  • Gaskets and sealing materials – Selected with accuracy based on requirement specification.
  • Measuring equipment – Measuring instruments and connections for fixed installation / external connection (density monitor SF6, vacuum instrument, pressure gauge vacuum, pressure gauge high pressure, couplings for measuring equipment etc.)
  • Gas regulator – Gas regulators adapted according to gas type, pressure and flow with connection to gas cylinder. (N2 regulator, high flow regulators, regulators for alternative gas, gas cylinder connection according to American, English, Chinese standards.)
  • Hoses - Large range of hose sizes and hose types. Special hoses according to customer requirements (dimension, length, pressure, protective casing, reinforcement, coupling type etc.).
  • Filter type - Different types of gas filters to filtrate gas from particles, moisture and residual products. Size is adjusted according to need and flow rate (particle filter, SF6 filter etc.).
  • Process monitoring via router / sms / GSM. With this technology you can read measured values in real time, adjust operating functions, get any operational alarms and troubleshoot.
  • Electric cable 3x400V, 50Hz, for 16A connection. Selectable length.
