Two-stage compression architecture
The historical product page and model table identify PM-II as a two-stage screw compressor range.
Two-Stage Compressors
12 Documented Models
A historical B&D two-stage screw compressor range documented across 12 models from 22 to 250 kW.
Product overview
The 2021 B&D product catalogue documents PM-II as a two-stage screw air compressor range with twelve model records and three stated working-pressure levels.
The historical table specifies permanent-magnet synchronous drive, variable-frequency starting, and air or water cooling across the range. Current model availability requires confirmation.
Product features
The historical product page and model table identify PM-II as a two-stage screw compressor range.
The documented models use permanent-magnet synchronous drive with variable-frequency starting.
The 2021 specification table lists air or water cooling across all twelve PM-II model records.
