The core competitiveness of the AIRSTONE AS-7.5A lies in its proprietary oil-cooling system. Compared to traditional air-cooled air compressors, oil-cooling technology offers three revolutionary advantages, comprehensively ensuring long-term equipment operation:

AIRSTONE has custom-matched the AS-7.5A with a Xima 10HP professional cooler and a Changfeng 300# fan. This lubricating oil circulates efficiently away heat from the motor and main unit, quickly balancing the internal temperature of the equipment and maintaining an outlet compressed air temperature of only "ambient temperature + 12°C." Even in hot summer workshops or high-load continuous gas production conditions, this prevents problems such as decreased motor efficiency and accelerated aging of core components caused by high temperatures, ensuring consistently stable gas production efficiency.

The oil cooling system and the IP65-rated motor form the AIRSTONE dual protection system. The lubricating oil forms a sealed protective layer inside the motor, further isolating it from impurities such as dust and moisture. Whether operating in dusty building materials workshops, humid chemical plants, or high-dust mining environments, the AS-7.5A effectively reduces the risk of failure and extends the service life of the motor and airend, perfectly embodying the AIRSTONE brand DNA of "durability and reliability."

AIRSTONE‘s oil-cooling technology eliminates the need for high-speed air-cooling fans. Combined with the overall noise reduction design, the AS-7.5A maintains a noise level of ≤76±2dB (A), a 5-8dB (A) reduction compared to air-cooled compressors of the same power. This significantly improves the workshop working environment, reduces noise disturbance to operators, and demonstrates AIRSTONE‘s commitment to the harmonious integration of "man, machine, and environment."

AIRSTONE consistently selects the AS-7.5A‘s core components according to stringent standards, ensuring superior performance from the very beginning:

The unit utilizes a Taiwan Chiyou 7.5kW oil-cooled motor with a direct-drive design, achieving a transmission efficiency exceeding 98%. A 3600rpm speed ensures robust power output. Combined with a Zhongchen 7.5kW permanent magnet variable frequency inverter, AIRSTONE achieves intelligent variable frequency control, automatically adjusting motor speed based on actual air demand to avoid wasted no-load energy. This delivers 20%-30% energy savings compared to traditional fixed-frequency air compressors, embodying AIRSTONE‘s "Green and Energy-Saving" brand philosophy.

The Baosi YNT55A precision airend from Taiwan utilizes AIRSTONE‘s proprietary screw meshing process optimization to reduce energy loss during compression, providing the core support for a stable exhaust volume of 1.1 m³/min, ensuring high efficiency and cleanliness for every cubic meter of compressed air.

Equipped with a 10HP air filter, a WD719 oil filter, and a 10HP oil separator, this AIRSTONE triple filtration system strictly controls lubricant oil carryover in the outlet gas to ≤3ppm. Output cleanliness meets food-grade standards, making it a perfect fit for industries with stringent air quality requirements, such as electronics, food, and medicine, and in line with AIRSTONE‘s product positioning of "highly clean air production."

Equipped with a MAM6080 intelligent controller, it monitors key parameters such as pressure and temperature in real time. Combined with a Taji PT100 pressure and temperature sensor (temperature sensor specification M10x1), AIRSTONE achieves precise data acquisition. Combined with a safety valve, it provides comprehensive safety protection, ensuring zero-risk equipment operation.

The AS-7.5A demonstrates AIRSTONE‘s comprehensive strength with impressive specifications, fully meeting the needs of industrial production:

Gas Production Efficiency: With an exhaust volume of 1.1 m³/min and a stable exhaust pressure of 0.8 MPa, it continuously provides sufficient air supply for production line pneumatic equipment, packaging machinery, spraying equipment, and more, eliminating the need for frequent starts and stops, perfectly matching AIRSTONE‘s "high-efficiency gas production" product characteristics.

Energy Saving and Consumption Reduction: In addition to permanent magnet frequency conversion and oil cooling technology, AIRSTONE customizes 8L of 32# dedicated screw oil for the AS-7.5A, paired with a YL-4 oil filter bracket. This extends the lubricant change interval to over 2,000 hours, reducing maintenance costs and downtime, and helping businesses lower costs and increase efficiency.

Flexible Installation: Measuring only 880*700*830mm, AIRSTONE‘s compact design significantly reduces floor space, allowing for flexible placement in narrow workshop corners or centralized machine rooms. Its G1/2" outlet allows for direct connection to most downstream piping systems without complex modifications, delivering on AIRSTONE‘s promise of "easy adaptation."

Leveraging its core advantages of oil-cooled stability, energy efficiency, and high cleanliness, the AIRSTONE AS-7.5A seamlessly adapts to diverse industrial scenarios:

Harsh Operating Conditions: With the dual guarantees of IP65 protection and oil cooling, the AS-7.5A operates stably in high-temperature, dusty, and humid industries such as metallurgy, mining, and building materials. This addresses the dust and moisture concerns of traditional air compressors and demonstrates AIRSTONE‘s adaptability.

High Cleanliness Requirements: ≤3ppm The lubricant capacity is minimal, meeting the stringent requirements of industries such as electronic component production, pharmaceutical preparations, and food processing. This prevents oil contamination of products, helps companies obtain industry cleanroom certifications, and demonstrates the professionalism of AIRSTONE‘s products.

General Industrial Applications: Low noise, energy-saving, and easy-maintenance make it suitable for general industrial applications such as automotive parts, hardware processing, and textiles. It provides strong support for companies to reduce operating costs and improve production efficiency, continuing AIRSTONE‘s brand mission of "empowering industrial production."
