Five motors, 300 liters of reserve air and 8400W on a 380V three-phase feed — a central oil-free air plant for entire departments, floors and production bays.
Factory-measured data for the 300-1680*5-300L five-motor oil free air compressor.
Values for reference. Custom voltage, plug types and tank coatings are available for OEM orders.
The 300-1680*5-300L oil free air compressor sits at the top of the range: five 1680W motor-pump modules working in parallel on a 380V three-phase supply, feeding a 300-liter reservoir that delivers up to 700 liters per minute at 8 bar. It is sized not for a single room but for a whole department — a dental clinic with a dozen chairs, a laboratory wing, or a workshop where air tools run from morning to evening.
The logic behind five smaller motors instead of one large block is simple: heat and wear spread across five units keep each one far below its thermal limits, which is how the platform holds its sub-0.02% failure rate in fleet service. And because the modules are independent, the system degrades gracefully rather than failing completely — even with one motor out of action, 80% of the airflow remains online.
Everything about the air side is oil-free: no lubricant ever touches the compressed air stream, so there is no oil aerosol to remove, no condensate contaminated with oil to dispose of, and no filtration chain between the machine and your instruments. For facilities with existing three-phase distribution, installation is a breaker and a pipe run — nothing more.
The engineering decisions that let a 8400W machine behave like a set of small, quiet, dependable ones.
Load shared across five 1680W units means each runs cooler, quieter and longer than any single equivalent machine — and 80% of capacity survives a single-module fault.
A 300-liter reserve absorbs every demand peak an entire floor can throw at it, so pressure at the point of use stays flat and motor start-stop cycles stay rare.
8400W distributed over three balanced phases keeps conductor current, cable heating and contactor stress low — the right way to power continuous-duty equipment this size.
Phase-to-phase voltage sag on industrial networks is tolerated: the control system still starts the motors reliably, protecting electronics from brownout damage.
From unheated basements in northern winters to boiler-room summers, output stays within specification across the full tested range.
Electrical, thermal, mechanical and pressure safeguards form a five-fold protection net that keeps motor burnout below 0.02% across the installed fleet.
Cold-rolled steel laminations slow heat buildup, aluminum housings shed it fast, Class F enameled wire withstands high insulation temperatures, and an built-in thermal protector cuts power on overload.
One-piece cylinder sleeves eliminate seam-related friction and wear, keeping volumetric efficiency stable over years of continuous running.
What a five-motor, 300L central plant means for each kind of buyer.
One machine in the plant room, air piped to every chair — a dozen operators can work at once without anyone noticing a pressure dip.
Oil-free by construction, so analyzers, autoclaves and pneumatic valves receive clean air with no filter maintenance and no contamination audit risk.
A genuine flagship SKU with a five-motor story no competitor catalogue matches, export-grade crating, and warranty exposure minimized by the <0.02% failure record.
Your logo on the top model of a coherent range: colors, control panel graphics, packaging and manuals all customizable at practical MOQs.
Sites that already run a 380V board get a central air plant without converters, new substations or single-phase limitations.
Sizing calculations, plant-room layout and pipe-diameter advice come with the quote — so the system performs as designed from day one.
