PhaZair Single-Phase Screw Compressors
Compare 230 V variable speed screw compressor packages delivering 24–27 CFM, with floor-mounted and receiver-mounted options available with or without dryer.
Choose the Right PhaZair Configuration
PhaZair is designed for suitable sites that need a screw compressor but do not have a three-phase electrical supply. The right package depends on whether a receiver and refrigerated dryer are already available.
Floor Mounted
Best where a suitable receiver and air-treatment system already exist or will be specified separately.
Floor Mounted + Dryer
Useful where an existing receiver can remain in service but integrated moisture reduction is required.
Receiver Mounted
Combines the compressor and local air storage while allowing the dryer and filters to be selected separately.
Receiver + Dryer
The most complete packaged route, combining the compressor, receiver and refrigerated dryer.

| Configuration | Best Suited To | Additional Equipment |
|---|---|---|
| Floor Mounted | Sites with an existing receiver and air treatment | Separate receiver, dryer and filtration as required |
| Floor Mounted with Dryer | Sites retaining an existing receiver | Separate receiver; additional filtration if required |
| Receiver Mounted | Sites needing local air storage | Separate dryer and filtration as required |
| Receiver Mounted with Dryer | Sites wanting the most complete packaged installation | Additional filtration only where the process requires it |
Who is PhaZair designed for?
PhaZair is intended for suitable workshops and smaller industrial sites that require screw compressor performance but only have a 230 V single-phase electrical supply.
How should I choose between the four configurations?
Check whether the site already has a suitable receiver and dryer. Avoid paying for duplicate equipment where existing components are correctly sized and in good condition.
Is 24–27 CFM enough for my application?
Add the airflow requirements of tools and processes that may operate together, then allow for leakage and sensible future growth. Do not size from motor power alone.
Does the receiver increase the compressor's CFM?
No. A receiver stores compressed air and helps manage short demand peaks, but it does not increase the compressor's continuous delivered airflow.
Does the refrigerated dryer suit every application?
A refrigerated dryer suits many general workshop and industrial applications. Processes requiring a lower pressure dew point or a specific air-quality class may need additional treatment.
What electrical checks are required?
Confirm the available 230 V supply, protective device, cable sizing, local isolator and starting requirements with a qualified electrician before installation.

Send MessageThe Phazair-230 rotary screw air compressor provides a practical and innovative solution to one of the oldest challenges in compressed air. Designed specifically for users limited to a 230V single-phase power supply, it delivers industrial performance where three-phase power is unavailable.
For many rural and remote users, compressed air capacity has traditionally been restricted by motor size, leading to undersized compressors, multiple units, increased maintenance, poor air quality, and reduced reliability. The Phazair-230 overcomes these limitations with advanced technology, delivering significantly higher output from a single-phase supply.
Key features and benefits include:
- Rotary Screw Compressor Technology: Industrial-grade rotary screw air end designed for continuous operation, offering high reliability and long service life.
- Single-Phase Power Operation: Operates from a standard 230V single-phase power supply, making it ideal for sites without access to three-phase electricity.
- Advanced Control System with Inverter Drive: Intelligent control combined with a variable-speed inverter provides adjustable output and improved energy efficiency.
- Configurable Motor Power: The 5.5 kW motor can be electronically regulated to suit site power limitations while maximising compressor performance.
- High Air Output: Delivers up to 27 CFM (780 L/min) at 8 bar and 24 CFM (680 L/min) at 10 bar, offering more than double the effective capacity of conventional single-phase systems.
- Energy-Efficient Operation: Variable output ensures only the required air is produced, reducing energy consumption and operating costs.
- High-Quality Compressed Air: Available with an integrated refrigerated dryer to provide clean, dry compressed air suitable for demanding applications.
- Flexible Installation Options: Can be supplied as a floor-mounted unit or mounted on a 270-litre air receiver for maximum convenience and simplified installation.
- Extremely Quiet Operation: Low noise levels allow the compressor to be installed directly within the work area, improving comfort and reducing installation constraints.
- Industrial Performance with No Compromise: Delivers continuous-duty performance, reliability, and air quality without the penalties typically associated with single-phase compressed air systems.
