Datasheet
Product overview
Bolaite BLT S dual-drive PM variable-speed screw compressors from Bolaite (Shanghai) / Atlas Copco China brand
The current BLT S description identifies a dual-drive permanent-magnet variable-speed screw arrangement. It describes two compression/drive assemblies, two air filters and two intake valves. This dual-drive arrangement should not be confused with BLT II two-stage compression.
Its current family summary gives 200–250 kW, 0.7–1.05 MPa and free air delivery of 7.4–54.3 m³/min. The power, pressure and FAD bands describe the family. Request the exact model and selected-duty table; the range endpoints do not form a single guaranteed operating point.
The description identifies IE5 oil-cooled permanent-magnet motors and IP66 motor protection. These are motor-related statements, not a blanket enclosure rating or measured complete-package energy saving. Compare package input at the same delivery, pressure and inlet conditions, including part-load operation and auxiliary loads.
Provide the demand profile, operating hours, voltage/frequency, cooling conditions and required pressure after treatment and distribution losses. Ask how the offered control coordinates the two assemblies across normal, low and peak demand, and what maintenance and availability behaviour applies when one assembly requires attention. Agree selected model drawings, treatment scope, acceptance records and service responsibilities. Do not infer machine ambient limits from magnet-material temperature claims.
The accompanying original manufacturer illustration shows the BLT S internal layout. It is a technical illustration, not a photograph of a delivered unit.

Specifying a Rotary screw duty
| Duty | Write on the RFQ |
|---|---|
| 110 kW 10 bar rotary screw compressor | 10 bar(g) is not 8 bar with a different sticker. FAD falls as pressure rises. Write 110 kW and 10 bar together, then the flow you need at that point. |
| 22 kW VSD screw compressor | 22 kW VSD is a flow band, not a single nameplate FAD. The plant needs min/max flow at the working pressure, or it will quote a fixed-speed machine with an inverter sticker. |
| 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. |
