LasGAR Basic / LasGAR Plus piezo proportional cutting gas pressure regulators for laser cutting machines, input up to 40 bar, output 0.1–30 bar
Country: Switzerland · Model: LasGAR Basic / LasGAR Plus
LasGAR Basic and LasGAR Plus proportional cutting gas pressure regulators with a piezo drive accept up to 40 bar at the input and deliver 0.1–30 bar at the output. The built-in gas selection valves and the electronics are assembled in one compact unit, which is installed next to the cutting head of a flat-bed laser cutting machine.

- piezo-controlled 3/2-way proportional valve with pilot valves and built-in gas selection valves (up to 3–4 gases)
- Cutting gases
- oxygen, nitrogen, compressed air, argon; quality per ISO 8573-1:2010 (3:2:2)
- LasGAR Basic (LGRB)
- input up to 30 bar (O2 up to 20 bar), output 0.1–20 bar (O2 up to 13 bar), flow 1200 l/min (p1 = 6 bar)
- LasGAR Plus (LGRP)
- input up to 40 bar (O2 up to 16 bar), output 0.4–30 bar (O2 up to 15 bar), flow > 1600 Nl/min

Description
The actuator is a piezo element weighing less than 10 g with a response in the millisecond range, stepless resolution and consumption in milliwatts. The low weight makes it possible to install the regulator at the cutting head, and short gas lines reduce gas losses, so the pressure changes in about 200 ms. The regulator works with oxygen, nitrogen, compressed air and argon per ISO 8573-1:2010 and is powered from 24 V DC. The pressure can be set with an analog signal of 0–10 V or 4–20 mA, or digitally through EtherCAT and Profinet. The device has been tested for acceleration up to 30 m/s² during positioning and 20 m/s² during cutting. It complies with CE and RoHS, and for EMC with EN 61000-6-2 / 6-4. The SMART option transmits data on the state and remaining life via Bluetooth.
How to choose
The choice starts with the laser power. LasGAR Basic (types LGRB0–LGRB3, LGRBF2, LGRBF3) is designed for low and medium power, with a nominal pressure of 30 bar. LasGAR Plus (LGRP0, LGRP2, LGRP3, LGRPF2, LGRPF3) is designed for high-power lasers, and an output pressure up to 28–30 bar is suitable for thick sheet, while the increased flow cross-section keeps the pressure from dropping on large nozzles. If a nitrogen-oxygen mixture is needed right on the machine, look at the LasGAM system.

FAQ
How accurately does LasGAR Basic hold the pressure?
In the range up to 10 bar at 5–45 °C the deviation is ±0.03 bar, above 10 bar ±0.2 bar. Pressure stability is ±0.01 bar, and repeatability is less than 1 % of the upper range limit.
What is the gas flow of LasGAR Basic and LasGAR Plus?
Basic passes 1200 l/min at p1 = 6 bar and delivers 0.1–20 bar, for oxygen up to 13 bar. Plus gives more than 1600 Nl/min and 0.4–30 bar, for oxygen up to 15 bar, and accepts up to 40 bar at the input (oxygen up to 16 bar).
Which gases and air quality are permissible for LasGAR?
Oxygen, nitrogen, compressed air and argon of quality ISO 8573-1:2010 (3:2:2). The control air is 4.5–10 bar, compressed air or nitrogen.
What are the weight and degree of protection of LasGAR regulators?
Basic weighs 0.5–3.9 kg, Plus 0.6–3.45 kg, and the version with 3 pilot valves 2.65 kg with dimensions of 175 × 139 × 76.5 mm. The degree of protection is IP50, ambient temperature −5…+45 °C.
