Import Air Filter Qac Series — Buy in Bulk from Supplier in China

The QAC Series is a combined air filter regulator lubricator (FRL) unit designed for pneumatic systems requiring integrated air preparation. It incorporates a filtration stage, pressure regulation, and oil lubrication in a single modular assembly, reducing the need for multiple inline components. The unit features an adjustable pressure range and a transparent polycarbonate bowl for visual monitoring of condensate and filter element condition. Standard port configurations are typical for this product category, though buyers should confirm thread type and port size with the supplier. Uneven wear across pneumatic tools often signals inadequate lubrication, making the built-in lubricator a critical feature for maintaining cylinder and valve performance over extended cycles.

Construction centres on a die-cast aluminium body with internal components manufactured to standard pneumatic FRL tolerances. The filter element is typically a sintered bronze or polyethylene type with a standard 5 micron to 40 micron rating, though the exact grade and replacement interval should be verified. The transparent bowl material is standard polycarbonate, which offers chemical resistance but requires protection from direct UV exposure and certain compressor oils that can cause crazing. A manual drain is typical, though an automatic float drain may be available as a variant. Pressure regulation is usually via a diaphragm-type valve with a locking adjustment knob to prevent inadvertent setting changes during vibration-heavy operation.

Primary applications include compressed air systems in automotive assembly, food and beverage packaging, pharmaceutical manufacturing, and general automation where ISO 8573 air quality classes must be met. Buyers are typically equipment OEMs, maintenance contractors, and industrial distributors who specify FRL units as part of complete pneumatic circuits. For import from Shanghai Sunfine Filtration Technology Co.,Ltd, confirm whether the QAC Series is offered with BSP or NPT threads, the maximum inlet pressure rating, and whether the lubricator uses a sight-feed dome or a micro-fog design. Also verify if the unit is supplied with mounting brackets and pressure gauges as standard or as optional accessories.

Shanghai Sunfine Filtration Technology Co.,Ltd is headquartered at Room 702, Unit 3, No.388 Pangu Road, Baoshan District, Shanghai 201900, China. The company holds a 'harbor' trust tier, which represents a baseline verification level on the platform used for this listing. Notably, the supplier shows a response rate of 0.00% with zero average response hours recorded, indicating that direct communication before placing an order may be unreliable. Buyers should factor this into their sourcing timeline and consider whether alternative contact channels or a third-party verification step is necessary before committing to an order.

The supplier's profile does not disclose factory size, year of establishment, annual revenue, employee count, or specific clientele. No ISO 9001, ISO 14001, or CE certificate numbers are provided in the source data, and claims to certifications in the original description cannot be independently verified from this listing alone. The company positions itself as a filtration technology specialist, with the QAC Series representing its integrated FRL offering. Buyers should request a company brochure, factory audit report, or video verification to substantiate manufacturing capability before finalising terms.
