Import Aluminum Alloy Fume Extraction Arm — Buy in wholesale FOB from Supplier in China

Shaoxing Keen Lab Equipments Co., Ltd. produces the Model Kp8-3 Aluminum Alloy Fume Extraction Arm for targeted contaminant capture in welding, chemical handling, and manufacturing environments. The 75 mm diameter aluminum alloy tube provides a rigid yet lightweight backbone, while high-grade polypropylene joints enable 360-degree swivel rotation for precise positioning over emission sources. The 304 stainless steel centre bolt and brass adjustable joint knob with internal stainless steel bearing form the mechanical core, resisting corrosion from acidic or solvent-laden exhaust streams. A manual damper knob allows operator control of extraction airflow, and the dome or cup hood is offered in polypropylene or polycarbonate with colour and transparency variants. The maximum movement radius is specified at 1,600 mm, a dimension that determines workstation coverage and ceiling mounting height calculations.

The polypropylene joint material is selected for chemical resistance and low friction, though its performance under sustained exposure to high-temperature fumes (above 80 degrees Celsius) requires verification for specific applications. The low-friction treated rubber sealing ring maintains joint integrity while permitting smooth repositioning without loosening. The injection-moulded plastic mounting bracket is produced from a complete mould, a manufacturing detail that suggests dimensional consistency for panel attachment. Aluminum alloy tube wall thickness, anodising or coating specification, and maximum allowable internal negative pressure are not stated in the source data, but are critical for matching to centrifugal fan curves and static pressure requirements. Standard industrial practice for similar arms uses 1.0 mm to 1.5 mm wall thickness with plain or mill finish aluminum.

Buyers include occupational health and safety managers, laboratory furniture integrators, and industrial ventilation contractors serving welding fabrication, pharmaceutical synthesis, and educational research facilities. The extraction arm is typically paired with a portable or central dust/fume collector, requiring matched airflow in cubic metres per hour and static pressure in pascals. Installation options include ceiling, wall, or benchtop mounting via the supplied bracket. Import procurement should confirm whether the arm is supplied with ducting connection diameter standardisation (typically 75 mm, 100 mm, or 125 mm), and whether adaptors are available for existing extraction infrastructure. The supplier location in Xinchang County, Shaoxing, Zhejiang Province, positions the factory within China's eastern manufacturing belt with Ningbo-Zhoushan Port access for international shipment.

Shaoxing Keen Lab Equipments Co., Ltd. is based in Provincial High-Tech Industrial Park, Xinchang County, Shaoxing City, Zhejiang Province, China, 312500, operating within a designated technology zone that may offer tax or customs facilitation advantages. The supplier holds a Harbor trust tier, yet the response rate is recorded at 0.00 percent with zero average response hours, so direct communication channels and responsiveness must be tested before order commitment. The company name and product range suggest specialisation in laboratory equipment rather than heavy industrial ventilation, which may influence design consultation depth for non-laboratory applications such as welding fume.

The source data does not disclose year of establishment, factory floor area, number of employees, annual revenue, or specific export markets. No certifications (ISO 9001, CE for machinery directive, or ATEX for explosive atmospheres) are mentioned. The product branding "Tof" is noted as the brand name, but trademark registration status and geographic coverage are unknown. Buyers should request a company registration certificate, VAT invoice sample, and at least two reference customers in comparable industries before advancing beyond initial enquiry. The proximity to Ningbo port (approximately 80 kilometres) is favourable for containerised export, though inland trucking arrangements and export customs broker engagement need explicit confirmation.
