Ingersoll Rand UP6-7.5-125 80 Gallon Air Compressor
This Ingersoll Rand air compressor features a 7.5 horsepower motor designed for single-phase 230V power supply. It includes an ODP electric motor and an air-cooled aftercooler for reliable cooling during operation. The 80-gallon horizontal tank supports continuous air delivery, producing 28 CFM at 125 PSI, ideal for moderate industrial applications.
The compressor is engineered for quiet operation at 65 dB, making it suitable for installation close to your workspace. Its auto start/stop control optimizes energy use by running only when needed. The unit is housed in a NEMA-1 enclosure providing basic environmental protection.
American Rotary Phase Converter AR20-20 HP
The American Rotary AR20-20 HP phase converter is designed to convert single-phase 208-240V power into three-phase 230V power for running industrial motors up to 10 HP light load or 20 HP in combination loads. It is ideal for applications needing reliable conversion to support air compressors and motor loads.
This rotary converter supports rotary phase conversion up to 28 amps, with a focus on motor and CNC applications. It handles light to moderate loads efficiently and allows easy integration in workshop and industrial environments where three-phase power is unavailable.
HPDAVV 3-Phase Rotary Screw Air Compressor 10HP
This HPDAVV 10HP rotary screw air compressor operates on three-phase 230V power and delivers a robust 33 CFM maximum airflow at a working pressure of up to 125 PSI. Featuring a built-in spin-on air oil separator, it reduces oil content in compressed air efficiently, prolonging compressor life and reducing maintenance.
The unit’s 3600 RPM motor provides stable air delivery suitable for industrial, automotive, and pharmaceutical uses. Note that phase conversion through a converter is not possible for this model; it must be connected to an existing three-phase supply or paired with a suitable phase converter.
HPDAVV 20HP Rotary Screw Compressor with Tank & Dryer
The HPDAVV 20HP rotary screw compressor includes an 80-gallon ASME tank and a refrigerated air dryer, designed for heavy-duty industrial use. Operating at three-phase 230V power, 60Hz, and 81 CFM airflow, it supports sustained air needs at 125 PSI.
This compressor features a modular design for easy maintenance, including spin-on oil and separator filters. Its microprocessor control system ensures reliable performance, while the refrigerated dryer improves compressed air quality by removing moisture before air reaches tools and equipment.
HPDAVV 3-Phase Rotary Screw Air Compressor 20HP
This HPDAVV 20HP three-phase rotary screw compressor delivers industrial-grade performance with up to 81 CFM airflow at 125 PSI. It features a robust microprocessor controller and an integrated spin-on air oil separator for efficient operation.
Designed for industrial applications, this compressor provides reliable output for continuous operations. It requires a three-phase power supply and is not compatible with single-phase input via simple converters, emphasizing the importance of selecting an appropriate phase converter for single-phase environments.
Buying Guide for Phase Converters for Air Compressors
Understanding Phase Conversion Needs
Air compressors designed for three-phase power often require phase converters when only single-phase supply is available. Make sure to understand the motor type and power rating of your compressor to select the correct converter size. Light loads and moderate loads have different requirements than heavy-duty industrial motors.
Converter Types and Capabilities
- Rotary Phase Converters: Suitable for running multiple motor loads and varying demands. They are versatile and reliable for heavy-duty industrial use.
- Static Converters: Usually limited to starting assistance for motors and cannot run the motor continuously.
- Digital and VFD Solutions: Offer precise control but may be more complex and costly.
Power Ratings and Compatibility
Choose a converter with a power rating higher than the compressor’s motor rating to ensure efficient startup and stable operation. For example, a 7.5 HP compressor should have a converter rated for at least 10 HP for longevity.
Note that some industrial compressors, like those from HPDAVV, are designed exclusively for three-phase power and may not work properly with basic converters without dedicated three-phase supply.
Noise and Efficiency
Look for converters that operate quietly, especially for indoor or workshop environments. Efficient converters reduce power losses and maintain stable voltage and current to the compressor, improving lifespan and operation cost.
Maintenance and Support
Converters with simple maintenance requirements and available customer support are ideal. Many rotary converters require minimal maintenance, but proper installation and periodic checks are necessary.
Additional Features
- Automatic controls such as start/stop to optimize power use
- Built-in protection features like overload and short-circuit safeguards
- Compact size and easy installation tailored to your workspace
