12V Centrifugal Blower Fan with 220V Variable Speed Regulator This 12V centrifugal blower fan offers precise speed control, strong airflow, and durable construction for cooling, ventilation, and combustion support in tight spaces. The included 220V infinitely variable speed regulator with a British specification plug lets you adjust the fan voltage between 3 and 12V to match airflow and noise needs. Key benefits Adjustable airflow and noise: Infinitely variable regulator controls voltage from 3 to 12V, allowing fine tuning of fan speed for the right balance of cooling and quiet operation. Strong, focused airflow: Produces up to 55 CFM at 5500 rpm (max), providing effective airflow for confined spaces and rapid ventilation. Durable and reliable: PBT housing offers good mechanical strength and thermal stability. Double ball bearings reduce wear and, with regular maintenance, help maintain long service life. Wide operating range: Designed to run stably in temperatures from 10 C to 75 C. Easy to use: Regulator plugs into 220V AC (British plug) and connects directly to the fan; no complex wiring required. Important specifications Fan voltage: 12V (regulated) Regulator input: 220V AC with British specification plug Regulator output range: 3 to 12V (infinitely variable) Maximum airflow: 55 CFM at 5500 rpm Main material: PBT Bearing type: Double ball bearings Operating temperature range: 10 C to 75 C Practical applications Electronics cooling: Use in computers, home media cabinets, inverter projectors, or 3D printers to improve ventilation in confined enclosures and help manage component temperatures. Barbecue and hearth support: Concentrates airflow to revive embers or strengthen flames for indoor fireplaces, wood burning stoves, outdoor barbecues, and camping stoves, replacing manual blowing. Appliance ventilation: Suitable for grills, refrigerators, humidifiers, and similar devices where controlled, compact airflow and adjustable speed are required. What makes it stand out Simple, plugandplay speed control with a 220V regulator and British plug for easy installation. Material and bearing choices that prioritize stable performance and longevity in a range of operating temperatures. Versatile use across cooling, ventilation, and combustion support tasks where compact, adjustable airflow is needed. Maintenance tips Keep the fan and regulator clean and of dust for reliable performance. Periodic lubrication and inspection of bearings will help prolong service life.
