Permanent Magnet Variable Frequency Aerator

This aerator features a gearless direct-drive design powered by a brushless DC motor, reducing maintenance requirements while improving operating efficiency. The intelligent variable frequency control system provides stable performance under fluctuating voltage conditions and helps save energy. With an integrated waterproof controller, corrosion-resistant materials, and a lightweight structure, the aerator is suitable for long-term use in both freshwater and seawater aquaculture environments.

Direct drive efficiency: Up to 90%
Energy saving: More than 30%
220V operating range: 160V–220V
380V operating range: 280V–400V
Waterproof rating: Near IP67 level
Float material: PE
Central flange bracket material: PA
Connecting bracket material: 304 stainless steel
Operating Instructions

The aerator is designed for easy installation and operation by a single person. The integrated controller automatically adjusts to voltage fluctuations during operation, while the soft-start function ensures a gradual startup to reduce water disturbance. For 380V models, phase loss protection helps maintain normal operation and protects the motor from damage.
