2. Product Introduction

This series of compressors is built around asynchronous electric motors, ensuring high efficiency and steady operation. By combining oil-free piston technology with precision engineering, the compressors are capable of producing stable airflow under varying loads. Key benefits include reduced vibration, low noise levels, long service life, and protection that meets IP67 standards. With working temperatures ranging from -40°C to 75°C, these compressors are engineered to withstand extreme operating conditions, making them suitable for fleets across diverse regions.

TRION asynchronous oil-free piston electric air compressor family is available in multiple models, allowing customers to select the unit that best matches their operational requirements. Each product undergoes rigorous testing to ensure compliance with energy efficiency standards and safety certifications, supporting consistent long-term performance.

3. Product Categories by Model

To accommodate different vehicle types and operational needs, the product line is divided into four distinct models. Each option provides a balance between airflow, power, and compact design, ensuring customers can choose the right compressor for their fleet.

• TY1.8F (1.8 kW / 160 L/min):
   Ideal for small and light-duty vehicles. Compact dimensions make it easy to install in limited spaces while maintaining steady airflow for braking systems and auxiliary components.
• TY3.0FB (3.0 kW / 280 L/min):
   A practical solution for medium-duty logistics trucks. It provides higher output capacity and longer service cycles, supporting frequent urban delivery operations where reliability is crucial.
• TY4.0F (4.0 kW / 400 L/min):
   Designed for heavy-duty buses and intercity vehicles, this model delivers the airflow required to operate braking, suspension, and pneumatic systems at high frequency without performance loss.
• TY5.0F  (5.0 kW / 500 L/min):
   The largest unit in the series, engineered for high-capacity applications and special-purpose vehicles. It delivers robust performance under heavy-duty conditions while maintaining low vibration and minimal noise.

By clearly defining these categories, customers can match each asynchronous oil-free piston electric air compressor to their vehicle platform, ensuring optimized investment and lower operating costs.
