Recently, two flagship products of Hopeleed — the Air-cooled 4-Impeller Paddlewheel Aerator (0.75kW) and Air-cooled 6-Impeller Paddlewheel Aerator (1.5kW) — have successfully passed official certification testing by the Chinese Academy of Fishery Sciences (CAFS).
Both models delivered exceptional core performance in the certification tests:
Air-cooled 4-Impeller Paddlewheel Aerator (0.75kW)
Oxygenation Capacity: Measured at 1.212 kg/h, exceeding the national standard of ≥1.20 kg/h with stable and reliable operation.
Power Efficiency: Reaches 1.768 kg/(kW·h), around 36% higher than the national standard of ≥1.30 kg/(kW·h). Higher efficiency per kilowatt delivers greater oxygen output and significantly reduces energy costs for aquaculture operations.
Air-cooled 6-Impeller Paddlewheel Aerator (1.5kW)
Oxygenation Capacity: Recorded at 2.537 kg/h, a 15.3% improvement over the national standard of ≥2.20 kg/h. Its strong oxygenation capacity rapidly raises dissolved oxygen levels in water, making it ideal for high-density intensive aquaculture.
Power Efficiency: Reaches 1.838 kg/(kW·h), 31.3% above the national standard of ≥1.40 kg/(kW·h), delivering notable cost reduction and productivity gains for large-scale fish farms.
As a professional aquaculture equipment manufacturer, Hopeleed upholds high efficiency, energy conservation and durability as its core R&D principles. The favorable CAFS test results fully validate our strong technical capabilities and reliable product quality. Moving forward, we will continue to advance aquaculture equipment development and launch more energy-efficient solutions, supporting fish farmers in sustainable aquaculture while boosting their profitability and harvest quality.
