Import Air Horn — Buy in Bulk from Supplier in China

This air horn operates at dual voltage, 12V or 24V DC, and produces acoustic output through two zinc alloy trumpets of 190 mm and 250 mm length. The unit is designed for automotive, marine, and industrial alerting applications where immediate auditory warning is required. Zhejiang Alpex Auto Parts Co., Ltd packages the product at 20 pieces per carton with a total carton weight of 24-26 kg and outer dimensions of 66 x 35 x 51 cm, indicating a compact shipping profile suited to consolidated container freight from Zhejiang province.

The zinc trumpet construction offers corrosion resistance in outdoor and marine environments, though the specific coating specification, such as chrome plating or powder coat thickness in microns, is not stated in the source data. The dual-tone configuration, generated by the unequal trumpet lengths, typically produces a fundamental frequency around 350-450 Hz with harmonic overtones that improve directional audibility. Standard air horn compressors in this class draw 15-25 amperes at 12V and require robust wiring with appropriate gauge cable and fused protection to prevent voltage drop and fire risk. The compressor diaphragm material, whether reinforced rubber or polymer composite, and its cycle life rating are not provided and should be confirmed with the supplier.

Target buyers include fleet operators, marine vessel outfitters, construction safety officers, and emergency vehicle upfitters who need compliant warning devices. The listing cites FOB or CIF shipping terms and indicates flexible MOQ, though no minimum quantity, unit price, or lead time is confirmed. Payment is not specified in the extracted data. Buyers should request compressor flow rate in litres per minute, sound pressure level in decibels at 1 metre, and any ECE, SAE, or Coast Guard compliance certification to validate fitness for the intended duty cycle and regulatory environment.

Zhejiang Alpex Auto Parts Co., Ltd is located in Auto & Motor Parts Industrial Zone, Tangxia Town, Rui'an, Zhejiang, 325204, China, a region with dense concentration of automotive component manufacturing and supporting logistics infrastructure near Wenzhou port. The supplier holds imported tier and harbor trust tier classification, with a response rate of 0.00 percent and zero recorded average response hours in the current data snapshot. This communication profile warrants direct testing of inquiry responsiveness before order commitment, as harbour tier alone does not guarantee active account management.

No information is provided on year of establishment, factory size, production lines, annual revenue, or headcount, so scale and specialisation must be assessed through direct engagement. The listing mentions various certifications ensuring compliance with industry standards but names no specific certificates, test houses, or regulatory marks. Buyers should request ISO 9001 or IATF 16949 scope certificates, material composition reports for the zinc alloy, and any third-party test reports for sound level, salt spray corrosion, and electromagnetic compatibility. The absence of confirmed MOQ, price, and lead time in the source data means all commercial terms require written clarification from Zhejiang Alpex Auto Parts Co., Ltd before contract.
