Low pressure screw air compressor

Low Pressure Screw Air Compressor

Low Pressure Air Compressor : AirHorse specially designs its low-pressure compressors with advanced inline vector control* and PID control technology, enabling fast response while ensuring safety and reliability.

What is a Low Pressure Compressor?: Low pressure air compressors are classified based on their discharge pressure, typically ranging from 1 to 10 MPa. They are available in various types, including piston, diaphragm, screw, and centrifugal models.

ACCESSORIES INTRODUCTION

The twin-screw air end features the latest rotor profile and high-precision machining, minimizing compressed air leakage and reducing power consumption—ultimately saving money for customers.
The air end offers excellent power balance with no unbalanced inertial forces, allowing the machine to operate smoothly at high speeds. It is compact in design, lightweight, and space-efficient.
It features strong adaptability with forced air delivery, ensuring that airflow remains nearly unaffected by exhaust pressure and maintains high performance across a wide operating range.

Super first-class energy efficiency, energy saving and more efficient (Three-phase asynchronous motor).

The three-phase asynchronous motor used in AirHorse compressors has been tested by a national energy efficiency laboratory and meets the national first-level energy efficiency standard.

High protection level design

Safety and reliability are ensured with the IP54 high-protection grade motor design, effectively preventing malfunctions caused by harsh environmental conditions

AirHorse brand three-phase asynchronous motors ensure long-term, efficient operation.

Thanks to high energy efficiency and an added service factor, the motor is less prone to overload and premature aging, ensuring long-term performance and efficiency.

INTERNAL SYSTEM DESIGN

Reasonable motor selection and related electrical system design
Reasonable intake system design and component selection
Optimized main exhaust pipe design to minimize pressure loss.
Reasonable design and selection of the oil-air separation system
Reasonable piping system design to minimize pressure loss.

TOUCH SCREEN CONTROLLER

Newly developed operation panel, simple and easy to understand it.

Energy-saving mode and remote operation switching can be directly controlled from the operation panel. In case of a fault, the display screen shows the error details, enabling quick troubleshooting and recovery.

A single-touch switch allows for easy adjustment of the control pressure setting.

Power-saving pressure adjustments and safety controls can be easily managed through the operation panel.
