The latest 5.5 kW TVD+ series permanent magnet two-stage variable-frequency screw air compressor

The latest 7.5 kW TVD+ series permanent magnet two-stage variable-frequency screw air compressor

The TVD+ series 7.5 kW permanent magnet two-stage variable-frequency screw compressor combines a two-stage compression unit with an IE5-class permanent magnet variable-frequency motor, delivering overall efficiency 15–20% higher than China's National Grade 1 energy standards—a cost-effective energy-saving solution specifically designed for small workshops.

1. The two-stage compression unit employs a 1:10 taper direct-drive mechanism with over 95% contact area, ensuring low operational vibration and extended service life.

2. Equipped with an IE5 oil-cooled integrated permanent magnet motor, it achieves a power efficiency of up to 96%, saving 20–30% electricity compared to traditional asynchronous motors.

3. The intelligent frequency converter dynamically adjusts gas consumption in real time, minimizing idle waste and reducing operational costs.

4. The ultra-quiet design produces only 70–72 dB of noise, 8–10 dB lower than comparable products, ensuring hassle-free operation in close workshop environments.

5. Equipped with the AirLink IoT smart IoT platform, it supports remote device monitoring, fault alert notifications, and collaborative management by multiple users, enabling real-time tracking of device operation status.
