MICRO-SPEED F Series Variable Speed Screw Air Compressor – 4kW to 5.5kW
Product Details
The MICRO-SPEED F Series is a compact range of floor-mounted variable speed screw air compressors designed for workshops, engineering facilities and smaller industrial compressed air applications.
Available in 4kW / 5.5HP and 5.5kW / 7.5HP motor sizes, each model can be specified for either 230V single-phase or 400V three-phase supply. This makes the range particularly useful for premises where three-phase power isn't available, while retaining a three-phase option for conventional industrial installations.
The variable speed design allows compressor output to respond to compressed air demand, with an operating pressure range of 6–10 bar. The 4kW models provide a minimum output of 10 CFM and maximum output of 16 CFM at 9.5 bar, while the 5.5kW models provide 12 CFM minimum and up to 21 CFM at 9.5 bar.
Available Variants:
| Model | Part Number | Motor | Supply | Min Output | Output @ 9.5 Bar | Pressure Range |
|---|---|---|---|---|---|---|
| MICRO-SPEED 4-10-F-230V | XLPM5.5-10-230V | 5.5HP / 4kW | 230V 1 Phase | 10 CFM | 16 CFM | 6–10 Bar |
| MICRO-SPEED 4-10-F-400V | XLPM5.5-10-400V | 5.5HP / 4kW | 400V 3 Phase | 10 CFM | 16 CFM | 6–10 Bar |
| MICRO-SPEED 5.5-10-F-230V | XLPM7.5-10-230V | 7.5HP / 5.5kW | 230V 1 Phase | 12 CFM | 21 CFM | 6–10 Bar |
| MICRO-SPEED 5.5-10-F-400V | XLPM7.5-10-400V | 7.5HP / 5.5kW | 400V 3 Phase | 12 CFM | 21 CFM | 6–10 Bar |
The floor-mounted configuration is suited to installations where the air receiver, dryer and filtration equipment are already installed or will be selected separately. This provides flexibility when incorporating the compressor into either a new or existing compressed air system.
With both single and three-phase options and variable output, the MICRO-SPEED F Series is particularly well suited to smaller installations that require the efficiency and performance of a screw compressor without moving to a larger industrial package.
