Datasheet
Product overview
Power: 30 kW, DA-30+ · Pressure: 7 or 8 barg, selected 50 Hz duties · Flow: 6.04–6.07 m³/min, selected 50 Hz duties
DENAIR's DA direct-driven oil-injected screw range includes pressure-specific 50 Hz and 60 Hz selections. The DA-30+ catalog example uses a 30 kW motor and provides 6.07 m³/min at 7 barg or 6.04 m³/min at 8 barg on the 50 Hz rating. These values come from the named model table rather than the broad range advertised for all belt and direct-driven machines.
The brochure defines free air delivery using ISO 1217:2009 Annex C, with an absolute intake pressure of 1 bar and intake and cooling-air temperature of 20°C. Site altitude and inlet temperature therefore matter when comparing the published capacity with the air demand at the factory.
The DA-30+ package is listed at 1,650 × 1,050 × 1,300 mm and 915 kg, with an R2 outlet. Select the operating pressure, supply frequency and downstream treatment together. Larger DA models and water-cooled variants have different installation requirements and should be checked against their own drawings.
The same brochure lists DA-30+ 60 Hz FAD separately: 6.04 m³/min at 7 barg and 6.01 m³/min at 8 barg. Specify the actual supply frequency and obtain the current offered-model sheet. The original image shows the manufacturer’s screw-compressor assembly line, rather than a serial-number-specific DA-30+ delivery.

Specifying a Rotary screw duty
| 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. |
| 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. |
| Rotary screw compressor manufacturers in China | China already has more screw-compressor storefronts than a buyer can audit. This desk lists manufacturing plants against a duty sheet — kW, bar(g), FAD — and routes one English RFQ. |
