Both are 380V three-phase machines built from 1680W modules. The 300 runs five modules (8400W, 300L, 700 L/min); the 320 runs six (10080W, 320L, 850 L/min). If your measured demand sits near or above 700 L/min — or you expect the facility to grow — the 320 is the safer choice. Below that, the 300 costs less to buy and run.

The complexity is engineered out. Modules run automatically under one controller; there is no oil to manage anywhere in the system. Servicing means draining condensate, cleaning intake filters and, if ever needed, swapping one bolt-on pump cassette while the remaining five keep supplying air.

A 380V three-phase feed with a dedicated motor-rated breaker sized for the 10080W load per local code, correctly rated cabling, and earth bonding at the terminal box. Modules start in sequence, so inrush current stays moderate without any soft-start cabinet.

A dozen dental chairs peak around 60–70 L/min each, so the 320 covers them with room for sterilizers and lab benches. In workshops the same flow supports multiple spray stations, air tools and actuators working at once. The 320L tank absorbs short peaks well above the average figure.

For ten kilowatts, noise stays moderate thanks to 1400 RPM low-speed motors, but the right placement is a plant room, utility corridor or acoustic enclosure with ducted ventilation — the same standard applied to any central air system. We can review your layout before you order.

Export units leave the factory bolted inside a plywood crate on a pallet. On site, a pallet truck or forklift handles the main move; the built-in casters cover final positioning. Once placed, level the unit and anchor it for permanent installation.

No lubricant contacts the air stream: no oil checks, no oil changes, no oil-contaminated condensate, and no oil aerosol toward instruments or products. Routine care is limited to condensate draining and filter cleaning — tasks your existing staff can handle without special training.
