广东艾高装备科技有限公司 · Lubao, Sanshui, Foshan
Ecoair / Aigao builds compressors and supports compressed-air system projects
The company's chronology begins with the Guangzhou business in 2004 and separately records the Guangdong company in 2014. Put the actual manufacturing and contracting entity on the offer.
Its stated activities combine research, manufacturing, sales and service. The wider portfolio includes PM variable-speed screw, two-stage and low-pressure compressors, oil-free equipment, blowers, centrifugal machines and vacuum pumps.

YTJ15 · compact industrial screw
Use the demand pattern to specify this PM variable-speed package
The official catalog returns YTJ15 under 15 kW motor power and both 0.8 and 1.0 MPa filters. The detail describes a motor and airend on a common axis, oil filtration and oil-air separation.
It is an oil-injected compression route. Match receiver storage, drying and filtration to the end-use quality requirement.
- Demand to supply
- Normal flow, peak flow and duration, daily hours, pressure at the process.
- Selected unit to confirm
- Pressure-qualified delivery, minimum operating range, supply and room ventilation.
- Controller to confirm
- Actual protocol/version for data exchange; BPM132's RS485 specification is a separate model detail.
Make component details useful at handover
The controller description includes pressure, temperature and current curves plus stored faults. Ask for the actual alarm list, controller documentation and commissioning settings.
Confirm the fan and cooling arrangement from the offered unit's drawing. Do not use an inconsistent heading as a specification.
Size from actual output at the selected pressure. Motor power alone does not establish air delivery or the saving for your operating profile.
BPM132 · two-stage oil-injected screw
At 132 kW, the quoted volume changes with pressure
The two rotor stages share one housing with helical-gear drive. Oil spray in the interstage cooling passage cools the compressed mixture before the second stage.
The source table gives DN80, 2,900 × 1,900 × 2,110 mm and 3,600 kg. Confirm the connection drawing: the source's unit heading says Inch, but the actual designation is DN80.
| Discharge pressure | Source discharge volume |
|---|---|
| 0.7 MPa | 28.5 m³/min |
| 0.8 MPa | 28.0 m³/min |
| 1.0 MPa | 23.5 m³/min |
| 1.3 MPa | 19.5 m³/min |
Define cooling and controller integration with the compressor
- Motor: IP55 and class F in the manufacturer description; confirm actual plate and supply.
- Heat rejection: centrifugal cooling fan with variable-frequency control; obtain ventilation requirements and service access.
- Standard communications: Modbus RTU / RS485. Agree register mapping and which controller will supervise the station.
- Custom communications: Ethernet must be specified in the order; do not assume it is included.
DFV(G) · oil-free screw route
Select the compression mechanism, then the complete air-quality system
The manufacturer describes 4:6 screw rotors, timing gears and non-contact engagement, with no oil in the compression chamber. The package uses motor/airend coupling, HMI control and interstage cooling.
The family table spans 37–500 kW. Its pressure columns contain values or slashes; a slash is not a published rating to estimate by interpolation.
For food-contact or other sensitive processes, specify total oil, pressure dew point and particles at the point of use. Agree drying/filtration and applicable current model documents.
| Model / motor | 0.75 MPa | 0.85 MPa | 1.0 MPa |
|---|---|---|---|
| DFV(G)M75A/W 75 kW | 13.0 m³/min | 10.7 m³/min | 8.9 m³/min |
| DFV(G)M132A/W 132 kW | 25.3 m³/min | 23.0 m³/min | 20.2 m³/min |
The 75 kW entry lists DN65, 2,950 × 1,850 × 1,750 mm and 2,600 kg; the 132 kW entry lists DN80 and 3,200 kg. Confirm the full suffix, cooling-water or cooling-air duties, selected voltage/phase/frequency and foundation/access requirements.
DFV(G) model rows and quality enquiry →Turn the station requirement into an order scope
Ecoair's system-service portfolio extends beyond the compressor. Ask for a defined package and responsibilities; a catalog range does not mean every component or overseas service is included.
- 01 · User demand
- Process pressure, simultaneous flow, low-load periods, operating hours and expansion needs. Select the compressor row at the actual pressure.
- 02 · Installation
- Electrical supply, cooling utilities, room ventilation, altitude/ambient, transport route, lifting/foundation and maintenance clearances.
- 03 · Treatment and storage
- Receiver duty, dryer capacity and dew point, filter train, drains and distribution pressure loss. Agree delivered quality at a named measurement point.
- 04 · Control
- For BPM132: RS485/Modbus or specified custom Ethernet, register map, station controller and commissioning ownership. Confirm YTJ/DFV interfaces separately.
- 05 · Acceptance
- Model/serial identity, motor and total input, flow reference conditions, pressure, quality and noise measurement basis, current manuals and test records.
- 06 · Operating support
- Original maintenance parts, service schedule, start-up training and destination service/response responsibilities. Put the actual terms in the offer.
Send one pressure-qualified Ecoair requirement
Choose YTJ15, BPM132 or a full DFV(G) model. Include the operating profile and station boundary so the offer can identify the equipment, options and acceptance basis.
Prepare an Ecoair compressor enquiry →Ecoair selection questions
Does YTJ15's 15 kW label establish its air delivery?
No. The catalog filter identifies motor power. Request output at the offered pressure, rating conditions and minimum operating range for your demand profile.
Is Ethernet standard on BPM132?
The description specifies Modbus RTU / RS485 as standard. Ethernet is an order customization to define before purchase.
Can a slash in the DFV(G) flow table be estimated?
It is not a published duty point. Select a listed model/pressure pair or obtain a confirmed manufacturer rating for the exact required point.
Can BPM132 and DFV(G)M132A/W be compared by 132 kW alone?
No. They use different compression mechanisms and pressure-qualified flow values. Include delivered-air quality, pressure, reference conditions and total package input in the comparison.
