What RTFANS does

RTFANS (also doing business as Koolair) is a Hong Kong-headquartered, privately held industrial equipment manufacturer founded in 2003, with production operations in Dongguan, China's Songshan Lake High-tech Industrial Development Zone. The company specializes in two complementary product categories: High Volume Low Speed (HVLS) ceiling fans, offered across seven series with diameters from 1.25m to 7.3m, and evaporative air coolers (centrifugal, axial, portable, and residential variants) with airflow capacities from 20,000 to 60,000 CMH. Its proprietary technology stack incorporates permanent magnet synchronous motors (PMSM), VFD controllers, imported German NORD decelerators, SKF-VL bearings, and six granted patents covering fan blade geometry, safety (anti-drop device), and structural designs (mortise-and-tenon motor frame, cardan joint). The signature offering is the 'Fan & Cooler Combo' — a hybrid system RTFANS claims no other Chinese supplier delivers end-to-end — which combines HVLS destratification fans with evaporative cooling for large industrial and commercial spaces. All industrial HVLS fans carry a 10-year parts warranty.

RTFANS serves industrial facilities, warehouses, logistics centers, commercial buildings, agricultural operations, sports and religious venues, and the residential market, with named reference customers including BMW, Tesla, Huawei, Porsche, Disney Sport, SF Express (顺丰速运), SimeDarby, and Baiyun Port (广州白云机场). The company operates a dual go-to-market model: direct sales via a dedicated team of 11 export specialists and 8 named sales/administrative managers, complemented by an actively-recruited global distributor network and OEM/ODM custom manufacturing services. Distribution spans 80+ countries. Pricing is per-unit hardware with no recurring software or service component, ranging from $45 for residential coolers to $4,900 for high-capacity industrial coolers and $1,350–$2,950 for HVLS fans. Marketing reaches international buyers through LinkedIn, Facebook, YouTube, WhatsApp Business, technical blog content, case studies, and industry trade shows. The company is led by General Manager Eaglet Wang with a leadership team averaging 43 years of age, and operates with 251–500 employees; no external funding rounds have been disclosed.
