Features

Truly Exceeds Level 1 Energy Efficiency

Surpasses China's national Level 1 energy efficiency standard (GB/19153-2019);
Over 30% more energy-efficient than standard air compressors.

System Optimization

System pressure loss reduced to less than 0.2 bar;
Optimized triple filtration and pressure loss systems ensure stable and efficient long-term operation.

Independent Air Duct Design

Compressed air intake also uses a separate duct, drawing air approximately 8°C cooler than the internal machine temperature, improving compression efficiency.

Smart IOT

IOT remote control, standard with air energy operation and maintenance platform

Core Technology

Integrated Coaxial Design

This design reduces transmission loss to zero and achieves 100% transmission efficiency.(Patent No. 2014103573965)

Synchronous Motor with Stepless Speed Regulation

Electronic speed regulation is applied to the two-stage compression system, allowing both first- and second-stage compressors to achieve synchronous stepless speed adjustment to meet varying demands.

Energy-saving profile optimization

Through in-depth analysis of energy-saving needs and continuous optimization of product structure, Xinlei's technical team has continued to upgrade the V series profile with years of technical accumulation. With its high volumetric efficiency, reasonable drive contact points and small area of the exhaust side leakage triangle, this line has become one of the more energy-efficient lines in the screw line sector.

Machine structure

High-Efficiency Filtration System

Oil content reduced to less than 1.3+ mg/m³ with upgraded premium MANN oil separator elements, resulting in lower oil content and cleaner exhaust air;

High-efficiency oil filter removes impurities from the lubricant, providing clean oil for the rotor and bearings of the airend;

High-efficiency air filter removes dust and particles from intake air, protecting the rotor, bearings, and other key components from damage.

Two-Stage Oil-Cooled Compression Unit

The first- and second-stage airends achieve synchronous stepless speed regulation.

Featuring large rotors, low rotational speed, and a horizontal structure with a low center of gravity, the unit offers smoother operation and lower noise.

The integrated airend and motor structure eliminates transmission losses, achieving 100% transmission efficiency. (Patent No. 2014103573965)

Equipped with an IP65 oil-cooled motor, it offers high protection, no mechanical loss from bearings, no energy loss from cooling fans, low noise, and low vibration.

Motor efficiency reaches 95.5%, saving 4.1% energy, and is 3–10% more efficient than asynchronous motors of the same capacity.

Dual Inverter System — Constant Temperature & Constant Pressure

The electrical control cabinet is divided into independent hot and cold zones, enhancing the cooling performance of the inverters;

An enlarged radiator with anti-rust and anti-corrosion surface coating ensures easy cleaning, extended service life, and stable temperature control;

Low oil temperature prevents oil circuit coking, carbon buildup, and overheating issues;

The unit operates smoothly with extended lifespan, effectively avoiding shutdowns caused by high temperatures.

S-shaped Inlet Pipe Design

The S-shaped pipe effectively reduces noise caused by airflow impact and vibration by altering the airflow path and direction.

Water Cooler

Water, as a cooling medium, has a high specific heat capacity, enabling rapid and effective temperature reduction of the screw compressor to ensure efficient operation.

It features a compact size, low noise, and stronger adaptability to various environments.

IOT Technology

The cloud platform can record and provide the operating status and operating parameters of the wind turbines bound to the platform, as well as perform fault alarm and data recording analysis. Users can log in to the platform to realize remote monitoring and energy-saving settings management, enabling users to realize real-time equipment management. At present, the IoT cloud platform provides ANDRIOD, IOS, and PC clients, and open interfaces to link with third-party software such as ERP, providing users with more possibilities.
