10 HP VFD Rotary Screw Compressor

Rotary Screw Comes Standard with VFD and Star Delta Option

This unit comes equipped with both a Variable Frequency Drive (VFD) and a Star Delta configuration. One major benefit of having both setups is operational flexibility and built-in redundancy. For example, if you are running the compressor using the VFD and it fails, you can quickly switch over to the Star Delta setup, bypassing the VFD entirely. This allows the compressor to remain operational with minimal downtime, an essential feature in environments where consistent air supply is critical.

Additionally, the Star Delta configuration supports dual voltage operation (230V or 460V). Switching between voltages is simple: rewire the transformer, connect the appropriate incoming power, and change a setting in the controller. Once configured, the compressor is ready to run, offering versatility and ease of integration into a variety of electrical systems.

The Rotary Screw Air Compressor is the most efficient choice when considering variable speed applications across all types of industries. Compared to a vane-type air compressor, the Rotary Screw design does not rely on centrifugal force to operate. Vane-style compressors depend on high RPMs to extend and retract the vanes inside the cylinder, meaning they lose efficiency when running at lower speeds. In contrast, a rotary screw compressor maintains efficiency even at lower RPMs.

This allows the rotary screw unit to deliver consistent performance, operating at lower pressures while producing higher CFM (cubic feet per minute). The result is improved efficiency, especially in applications requiring higher PSI—up to 232 PSI—making it an ideal choice for demanding industrial environments.

 Single-stage air end

Offers a wide range of series, for different applications and pressure demands.

•  High efficiency and low noise

Patented 5 to 6 screw rotor profile is designed to operate at low tip speed with high volumetric efficiency. The male rotor has 5 teeth, the female rotor has 6. This tooth combination can improve energy efficiency, and decrease excessive fluid backflow, due to the similar circumference speed ratio of the two rotors.

• Low vibration and long service interval

Precise manufacturing screw rotors and high-quality bearings for up to 232 PSI discharge pressure. We use high-precision-manufactures rotors, which guarantee Airend long bearing service life and low vibrations.

•  Flexibility with PM motor and VFD Combination

It is available to work with PM motor or an inverter to gain power saving.

•  Easy for maintenance

 Compact design and few moving parts.

New Generation Controller

The MAM6090 controller is a user-friendly, commercial grade air compressor controller. This unit has a variety of key features that are extremely easy to use and set up in your application. Here are some of its key features:

The MAM controller has an auto-shutdown system that can sense when the unit is over pressure and will shut the equipment down. It has a maximum pressure setting that you can adjust to protect the unit.

The MAM comes equipped with optional wifi capability to allow you to check on your compressor remotely. You can monitor, diagnose and control your air compressor from anywhere in the world including being able to schedule maintenance intervals. The MAM will notify you when an alarm occurs, so you can address the issue immediately.

The automatic shut off feature is designed to shut the unit down if the voltage is too high or if any of the sensors (temperature, pressure, or air flow) are too high or low these settings can be changed in the controller according to your needs. This will protect you from an overheated motor and damage to the unit.

The proper use of equipment is important for the safety and well-being of those using the compressor. Keep track of maintenance services and preventative maintenance with a built in Clock and Date. The built in Light can be used for you to see the controller in poorly light area. Parameters allow for quick basic information to be accessed such as total running time, total load hours and services hours remaining for next service. It also gives you a detailed history of alarms making it easy to diagnose any issues. 

Programmed Scheduling – this controller can be programmed to start in the morning, shuts itself off at lunch, if needed and turns itself on based upon a pre-programmed schedule. If power is lost, it will automatically restart itself, eliminating the need for a maintenance crew to shut down or restart it after the loss of power. Master Slave – this controller can switch from one unit to another and maintain equal service maintenance hours among all units, it can connect 4 units together and control all of them from one controller (Master).

Industrial Motors

Specially designed for extreme duty applications, our motor series is constructed with a larger conduit box for easier connections, and has superior sealing for better environmental protection. Full cast iron construction is more robust than the standard rolled steel, ensuring reliability in even the most extreme work conditions. With longer fins all around for better cooling, this motor runs at a lower temperature, increasing the life of the winding insulation. A cooler running motor delivers higher efficiency

Service Parts

Serviceability is one of the key benefits of our air compressors. With high-quality components, maintenance is required less frequently than it otherwise would be. In cases where replacement parts are required, the compressor drive and other components can be easily serviced, allowing both the machine and the customer operation to get back up and running quickly. Proper filter maintenance is essential for your air compressors to run efficiently, last longer and prevent costly repairs. Change the filters on a regular basis, as it reduces the chances of component and air-end contamination.
