Import 9-19 High-Pressure Centrifugal Air Blower — Buy in Bulk from Supplier in China

The 9-19 series high-pressure centrifugal air blower is a direct-drive industrial fan designed for applications requiring sustained elevated pressure at moderate flow rates, classified by Chinese industry standard JB/T 3165. Fujian Chengda Blower Co., Ltd. manufactures this unit for pneumatic conveying, combustion air supply, and forced-draft systems where static pressure development takes priority over volume movement. The 9-19 designation refers to the impeller diameter ratio and outlet width series in China's centrifugal fan numbering system, indicating a high-specific-speed machine with backward-curved blades. The company's location in Fuzhou's Chendian Lake Industrial Area suggests a manufacturing base rather than purely trading operations.

Construction typically comprises a cast iron or welded steel housing with a single-suction, backward-curved bladed impeller dynamically balanced to ISO G6.3 or better. Bearings are usually grease-lubricated rolling-element type for the smaller motor-coupled sizes, with oil-lubricated journal bearings for larger direct-coupled or belt-driven configurations. The high-pressure characteristic derives from the relatively narrow impeller width and large diameter ratio, trading flow capacity for pressure development. Typical impeller materials are carbon steel or aluminium alloy, with stainless steel 304 or 316 available for corrosive service, though the buyer must confirm actual material specifications with Chengda.

Primary applications include pneumatic conveying of powders and granules in food, chemical, and mineral processing; combustion air for industrial boilers and furnaces; and process air in drying and cooling systems. The 9-19 series suits medium-pressure systems up to approximately 15-20 kPa depending on speed and diameter, beyond which multi-stage or positive displacement blowers become necessary. Buyers should confirm the specific impeller diameter, rotational speed, motor power, and performance curve for their operating point, as the 9-19 series covers a wide parameter range. The supplier's trust tier is 'harbor' with zero recorded response data, so direct technical consultation before specification is prudent.

Fujian Chengda Blower Co., Ltd. is located in the Chendian Lake Industrial Area, Ganzhe West, Fuzhou, Fujian Province, China, postal code 350100. The industrial area location suggests manufacturing or at least assembly operations rather than a purely commercial office. Fujian Province has a cluster of fan and general machinery manufacturers serving domestic and Southeast Asian markets, with Fuzhou port offering direct shipping routes. The company's trust tier is 'harbor', but its response rate is 0.00% with zero average response hours, indicating no recorded buyer engagement through the platform to date.

No production capacity, annual turnover, employee count, or client references appear in the available profile. The source description contains marketing claims about energy efficiency and international certifications that the buyer should verify independently, particularly any ISO certificates and their scope. The mention of 'flexible MOQ' and 'favourable shipping terms' in the source material are unsupported by specific figures. Buyers should request factory audit reports, actual performance test data for the specific 9-19 model of interest, and reference installations in comparable applications and climates before committing.
