Product overview
Power: 37 kW · DSPM-50A · Pressure: 8 / 10 / 13 bar · choose duty · Flow: 6.1 / 5.0 / 4.5 m³/min · paired duties
DSPM is Desran's oil-injected screw route with permanent-magnet variable-speed drive. In the selected DSPM-50A table entry, the motor is 37 kW. Published air delivery is 6.1 m³/min at 8 bar, 5.0 at 10 bar and 4.5 at 13 bar. Choose the pressure-matched point; the largest capacity does not describe a machine operating at every pressure.
The same entry lists 1,350 × 950 × 1,225 mm, 490 kg and a G1½ outlet. The original official photograph is marked DSPM-50A+, whereas the parameter table uses DSPM-50A. Agree the exact designation, revision, pressure version and electrical supply on the accepted offer and drawing rather than treating a gallery photograph as an order specification.
For a larger requirement, DSPM-100A is a separate 75 kW entry, giving 12.5 m³/min at 8 bar, 9.5 at 10 bar and 9.0 at 13 bar. Its listed dimensions are 1,800 × 1,200 × 1,570 mm and mass 980 kg, with G2 outlet. The same-power DSTPM two-stage machine has different delivery and mass; do not reuse this row for that architecture.
Provide demand variation, operating hours, ambient/intake conditions and available utilities. Agree delivery reference/test conditions, complete-package input and the control range before estimating consumption. Plan cooling airflow and maintenance access beyond the cabinet footprint, with receiver, drying and filtration sized for the selected duty. State downstream moisture, particle and oil limits separately from the compressor architecture.

Specification pages
Specifying a Rotary screw duty
| Duty | Write on the RFQ |
|---|---|
| Compressor for laser cutting | Choose the air system from the laser maker's gas specification. The compressor motor rating and laser power do not, by themselves, determine the required pressure, flow or air quality. Identify whether the supply is for cutting assist gas, machine services or both before requesting a package. |
| Compressor for a textile factory | Jet looms and spinning do not share a pressure. Write the machine OEM’s bar(g) and the hall FAD, then 50 Hz voltage for most Asian mills. |
| Compressor for CNC machines | Machine tools need dry, stable 7–8 bar air. Size from the cell, not from a round kW number a vendor likes to sell. |
