When you're dealing with underground airflow restrictions in mines or tunnels, the pressure buildup can seriously hamper productivity and safety, and what you really need is a fan that moves a lot of air without drowning out everything else in the process.
We've found these handle that balance pretty well, with the blade diameters ranging from about 500mm up to 1120mm and motor power from 5.5KW to 11.2KW depending on the model, and almost all buyers go for either the FBDNo6.0 or No7.1 units since they fit most standard ducting setups without modification.
Typical airflow runs from about 5,000 to 75,000 m³/h at pressures around 500-1200 Pa, and the noise level stays under 75 dB(A) at full speed—which is quieter than you'd expect for something spinning at up to 2900 rpm. Also, the effiency is pegged at 82% or higher, and that's on ISO and CCC certified units.
Lead times usually sit at 20 days or so for a standard bulk order, but if you need IP55 protection or insulation class F, we have to check stock on those variants, we use alumnum alloy for teh blades and steel for the housing, so it's pretty corrosion-resistant even in harsh environments—though honestly, they're not great for airstreams with heavy particulate above 20 ppm without a pre-filter.
MOQ for the FBD series is typically 10 units for standard specs, but we can discuss lower quantities for first-time orders or sample testing.
Lead time is usually 15-20 working days after order confirmation and deposit, depending on quantity and customization needs.
Yes, we include ISO and CCC certificates with every bulk order, and CE documentation can be provided upon request.
Absolutely, you can choose aluminum alloy for lighter weight or steel for higher durability, and we adjust the specs accordingly.
Store them in a dry, covered area between -20°C and +60°C, ideally off the ground to avoid moisture damage to the motor and blades.
