Import Bird Repeller — Buy in Bulk from Supplier in China

This bird repeller from Zhejiang 3f Industry Ltd. utilises ultrasonic frequency emission to deter avian species from agricultural, industrial and commercial premises. The device operates on 3F proprietary technology developed by a manufacturer established in 2007, with a sound output designed to be audible to birds yet outside human hearing range. The unit is constructed with weather-resistant housing for sustained outdoor deployment in varied climatic conditions, and is specified for straightforward installation without specialised technical expertise.

The core mechanism relies on piezoelectric ultrasonic transducers generating high-frequency acoustic pressure waves, typically in the 15-45 kHz range (standard for avian deterrent systems). The housing material is UV-stabilised ABS or polycarbonate blend, rated for continuous exposure to solar radiation and precipitation. Power is typically delivered via mains adapter or hardwired connection, with typical current draw in the 0.2-0.5 A range at 220-240 V AC (50 Hz). Coverage area per unit is influenced by transducer count, output wattage and environmental acoustics, with reflective surfaces and open terrain extending effective radius. The 3F designation refers to the supplier's integrated approach to frequency modulation, field coverage and form factor optimisation.

Primary buyers include agricultural cooperatives protecting grain stores and fruit orchards, warehouse operators managing logistics facilities, and facilities managers responsible for retail and municipal rooftops. The device serves as a non-lethal alternative to netting or chemical deterrents, aligning with environmental compliance requirements in export markets. Importers should verify CE marking or equivalent conformity assessment for EU destinations, and confirm IP rating for intended installation environment. Packaging is typically individual carton with polyfoam protection; bulk orders may utilise palletised shipment. FOB Ningbo and CIF terms are referenced, though specific freight arrangements require direct confirmation with the supplier.

Zhejiang 3f Industry Ltd. is located at 12 Building 801, Chengxin Road, No.1188, Yinzhou District, Ningbo, Zhejiang Province, postal code 315105, China. The supplier is classified as an imported-tier account on the platform, with a trust tier designated as harbour. The response rate is recorded at 0.00 percent, with an average response time of zero hours, indicating no historical engagement data is available through the platform interface. The company was established in 2007, giving it approximately eighteen years of operational history in its stated field.

The supplier profile does not disclose factory size, employee count, annual revenue, specific client references, or third-party audit results. The 3F technology referenced in product materials is proprietary to this manufacturer and should be evaluated through sample testing rather than taken at face value. Buyers are advised to conduct independent verification of business registration, factory existence through video inspection, and product performance claims via certified sample evaluation before committing to volume orders. No information is provided about R&D expenditure, patent holdings, or export licensing status.
