浙江志高机械股份有限公司 · Quzhou, Zhejiang
Compressor manufacture within a rock-drilling machinery business
Zhigao's company introduction dates the business to 2003. Its September 2025 articles of association identify Zhejiang Zhigao Machinery Co., Ltd. and the Qujiang headquarters, corroborating the legal identity.
The company describes four industrial parks with different roles. The Zhigao Power park brings machining, test equipment and compressor manufacturing together. Other parks concentrate on rock-drilling equipment, riveting/welding and heavy machinery; Zhigao Home supports employee/customer training.
For an order, identify the manufacturing and contracting parties and tie production/inspection documents to the selected model. The official Chinese site links to ZEGA's English catalog, whose export-company identity should not be confused with the manufacturing legal name.

Specify the package that will actually reach the site
The detail page identifies electric drive and uses a stationary breadcrumb; the higher-level list places the model under mobile electric equipment. The pictured cabinet is not proof of a road trailer. Agree mounting, lifting, transport, discharge connection and installation access.
The series' motor/control wording is inconsistent, while its parameter note identifies an e suffix for variable-frequency versions. Obtain the offered motor/controller version and starting/input data rather than assuming permanent-magnet drive or an inverter from the model number.
Rated FAD needs its manufacturer reference/test conditions for a comparison. Send tool consumption, working pressure, hose losses, ambient, altitude and site supply together.
Keep engineering-air models and industrial-air families separate
ZEGA's English electric-portable table lists the following different SPE models. They are not alternate ratings for 280SCFT-8, and they do not describe an oil-free package.
| Model | Motor / rated FAD | Rated pressure / stages |
|---|---|---|
| SPE460S-14.5 | 90 kW / 13 m³/min | 14.5 bar / single-stage |
| SPE845S-8 | 132 kW / 24 m³/min | 8 bar / single-stage |
| SPE740D-18 | 132 kW / 21 m³/min | 18 bar / two-stage |
The three rows state 380 V / 50 Hz and IP54. Select tool pressure and required delivery first, then the actual offered model's control, cooling, mounting and starting arrangement.
Zhigao Power · oil-free two-stage families
AS or AS·V: start with the demand profile
AS · fixed frequency
The original family heading is AS-8/10 bar. For a steady demand, ask for the selected model's duty sheet and the operating/control arrangement at the required pressure.
AS·V · variable frequency
The original family heading is AS·V-8/10 bar. For changing demand, request the offered model's minimum delivery, control range and package input across that demand profile.
These headings identify families; the reviewed category pages contain no individual model rows. Request model-specific delivery, input, cooling and supply details before comparison.
Define quality where the air is used
Agree oil, moisture and particle limits, the measurement point and applicable model test documents. Specify the compressor mechanism and downstream drying/filtration scope separately. The oil-free category name alone does not establish dry compression, Class 0 certification or medical-air approval.
Two practical enquiry routes
Mine, tunnel or drilling duty
- Tool demand: pressure, consumption, simultaneous tools and operating hours.
- Distribution: hose length/diameter, discharge connection and pressure loss.
- Site: ambient, altitude, dust, supply and starting arrangements. Generator selection needs input/current data and an engineering check.
- Delivery: cabinet mounting/transport, cooler and maintenance access, treatment and commissioning scope.
Industrial oil-free air
- Demand: peak/minimum flow, minimum user pressure and operating profile.
- Quality: oil/moisture/particles, measurement point and treatment scope.
- Utilities: supply, cooling, ambient/altitude and service space.
- Acceptance: full model, performance basis, applicable test records, manuals, maintenance and destination support.
Send the duty, not just a compressor size
State 280SCFT-8 or the selected AS / AS·V family, the user's pressure and demand, and the site's supply and quality requirements.
Prepare a Zhigao compressor enquiry →Zhigao selection questions
Is 280SCFT-8 a diesel compressor?
No. The original Chinese title and specification identify electric drive, 280 kW motor power and 380 V/50 Hz supply. An English label in the parameter image is a mistranslation of the motor-power field.
Does the cabinet photograph establish a towable package?
No. Confirm the supplied mounting, transport and lifting arrangement. The detail page and family list use different stationary/mobile classifications.
Can an SPE rating be applied to 280SCFT-8?
They are distinct models. The reviewed 280SCFT-8 rating is 55 m³/min at 8 bar; retain each SPE model's own pressure and delivery together.
Does the AS family heading specify a complete oil-free installation?
It identifies a family and pressure heading. Select the actual model, quality evidence, dryer/filter/receiver scope, cooling and supply configuration for the user's duty.
