Datasheet
Product overview
Power: Selected RG/RKG: 7.5–22 kW · Pressure: RKG EF selected rows: 1.6 MPa · Flow: RKG EF selected rows: 0.5–1.8 m³/min
Risan's laser-cutting page separates two integrated arrangements. The RG E table covers a screw compressor with receiver: RG10E is 7.5 kW with a 170 L vessel, RG15E and RG20E use 290 L, and RG30E is 22 kW with 380 L. The RG EF table adds a refrigerated dryer and precision filters: RG10EF uses 250 L, RG15EF/RG20EF use 340 L and RG30EF uses 480 L. The model suffix matters when specifying the included treatment and vessel.
The EF table lists distinct RKG high-pressure rows. RKG10EF gives 0.5 m³/min at 1.6 MPa and 7.5 kW; RKG15EF gives 0.85 at 1.6 MPa and 11 kW; RKG20EF gives 1.35 at 1.6 MPa and 15 kW; RKG30EF gives 1.8 at 1.6 MPa and 22 kW. Lower-pressure RG rows remain separate: RG20EF gives 2.3 at 0.8 MPa, 2.1 at 1.0 and 1.72 m³/min at 1.2 MPa. Do not combine the 2.3 flow with the RKG 1.6 MPa pressure. Full volumetric conditions, pressure reference and treatment pressure loss must be clarified.
The original family image shows RKG30EF with its receiver. This is a laser-cutting compressed-air package; the source does not establish PET-blowing performance or compressed air as a substitute for every oxygen/nitrogen cutting process. Provide the laser maker's gas specification, nozzle/process demand and simultaneous machine count, material/thickness and cycle. Agree pressure and flow at the machine inlet, dryer dew point, filter grades and acceptance measurement, vessel/destination requirements, electrical supply, drain behavior, installation and service access. Obtain the full machine and treatment documentation for the chosen arrangement.

Specification pages
Specifying a Laser-cutting screw duty
| Duty | Write on the RFQ |
|---|---|
| Compressor for laser cutting | Choose the air system from the laser maker's gas specification. The compressor motor rating and laser power do not, by themselves, determine the required pressure, flow or air quality. Identify whether the supply is for cutting assist gas, machine services or both before requesting a package. |
| 22 kW VSD screw compressor | 22 kW VSD is a flow band, not a single nameplate FAD. The plant needs min/max flow at the working pressure, or it will quote a fixed-speed machine with an inverter sticker. |
| 13 bar rotary screw compressor | 13 bar(g) is a laser and textile pressure, not a general 8 bar plant. Write FAD at 13 bar and the kW the site can feed. |
