At the laser machine
Specify pressure while cutting, nozzle/process requirements, peak demand and allowable water, oil and particles. Pressure at compressor discharge differs from pressure after treatment and piping losses.

Huitong Xinda: two-stage air, laser supply and low-pressure duties
Pair model flow with pressure, define the laser interface and clarify HL pressure units before sizing.
青岛汇通鑫达空压机有限公司 · JIMO, QINGDAO
Three compressor duties, three different comparisons
Qingdao Huitong Xinda develops, designs, manufactures and sells screw compressors. Its factory is in Lancun, Jimo District; the Chengyang direct-sales store is a separate location. Its portfolio also includes integrated packages, nitrogen-generation equipment and air receivers.

Two-stage: keep the pressure and flow paired
The described process uses lubricating oil in first-stage compression, oil-mist interstage cooling and second-stage compression. The manufacturer describes two stages in one housing with helical-gear drive. This is oil-associated compression; two stages do not establish oil-free air.
The category title starts at 11 kW, but the actual table starts with HV-15ⅡG at 15 kW. It lists variable-frequency starting. Obtain the offered motor and speed-control configuration rather than inferring an 11 kW row or a permanent-magnet design from the family label.
| Model / power / mass | 0.8 MPa | 1.0 MPa | 1.3 MPa |
|---|---|---|---|
| HV-22ⅡG 22 kW · 760 kg | 4.1 m³/min | 3.5 m³/min | 3.2 m³/min |
| HV-37ⅡG 37 kW · 980 kg | 7.1 m³/min | 5.8 m³/min | 5.4 m³/min |
Air cooling, direct drive and a printed −5 to +45°C environment are listed. Confirm site derating, heat rejection, actual footprint/outlets and service access. Noise/exhaust-temperature figures need measurement conditions. Compare speed range, turndown and total package input at the chosen duty; the volume label is not independently verified FAD.

Laser air: choose the delivered pressure, then define cleanliness
| Model | Motor | Discharge / flow |
|---|---|---|
| HD-11/13G | 11 kW | 1.3 MPa / 1.4 m³/min |
| HD-11/16G | 11 kW | 1.6 MPa / 1.2 m³/min |
| HD-22/13G | 22 kW | 1.3 MPa / 3.0 m³/min |
| HD-22/16G | 22 kW | 1.6 MPa / 2.6 m³/min |
The numerical table names HD; surrounding paragraphs name XD and XV. Confirm the offered model and control configuration. The published volume reference is not fully stated.
In the package
Agree dryer, filters, receiver, drainage, electrical supply and control/interlock scope. “Laser dedicated” does not establish a cleanliness specification, nitrogen generation or universal cutting quality.
HL FAMILY · SINGLE-STAGE / VARIABLE-FREQUENCY START
Low-pressure: resolve the source before comparing savings
The manufacturer targets low-pressure, high-volume use rather than unnecessary high-pressure compression followed by reduction.
- HL-45G
- 45 kW · 11.5 m³/min · 1160 kg
- HL-75G
- 75 kW · 19.2 m³/min · 1280 kg
- HL-110G
- 110 kW · 27.2 m³/min · 1480 kg
Claims of more than 30% savings require an actual baseline, pressure, demand and package-input test. Compare the offered machine at the agreed process pressure and demand profile, including treatment/network losses and usable control range.
Prepare the HL model and pressure clarification →What a useful proposal should contain
- Your duty: consuming process, shift demand/base/peak flow, point-of-use pressure and losses, operating hours and required outlet quality.
- The offered machine: exact model/control, same-condition capacity and package input, voltage/phase/frequency, site limits and model-specific installation/service-access drawings.
- The complete supply: treatment/receiver/drains, cooling-air route, controls/protection, manuals and consumables, commissioning and acceptance records.
- The delivery responsibility: warranty commencement/exclusions, training, destination service/parts and any required current certificate scope.
The company profile describes ISO9001 management standards. That does not establish a currently valid certificate for this particular order, and no certification badge is assigned from that statement alone.
Questions to settle before ordering
Is the two-stage machine oil-free?
The described process includes lubricating oil and oil-mist interstage cooling. Specify actual gas-path arrangement and treatment/air quality separately.
Can the HL pressure row be silently read as bar?
No. Its printed unit conflicts with the prose. Obtain the manufacturer's signed model-pressure sheet before selecting or converting it.
Does the laser compressor include all drying and filtration?
The category label does not define the complete supplied scope. Agree treatment, losses and air-quality acceptance at the cutting-machine interface.
Send the actual air duty
Choose HV two-stage, HD laser supply or HL low-pressure and include demand, delivered pressure, air quality and site conditions.

Specification pages for Huitong Xinda product types
| Duty | Write on the RFQ |
|---|---|
| 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. |
| 30 bar oil-free compressor | Specify whether 30 bar is gauge or absolute pressure, where it is required and how much air must be supplied at that point. A 30 bar working duty does not, by itself, identify a compressor architecture, motor size or air-quality class. |
| 50 Hz 380 V screw compressor | Chinese plants build 50 Hz 380 V packages every day. They cannot retag a 60 Hz 460 V nameplate in the quotation without a motor change. Write the supply first. |
| 40 bar PET compressor | PET blowing at 40 bar(g) is a high-pressure oil-free duty. Cavities, bottle volume and recovery pressure size the skid — not the word “PET compressor”. |
