Introduction
FBD Series (formerly BDJ60 series) Mine Explosion pressure-rotating axial ventilation, mainly used in coal mine as a push-local fans for the mining face and a variety of local ventilation chamber occasion, while , also applies to other mines and a variety of local ventilation tunnel ventilation plant together
This product has reasonable structure, complete specifications, high efficiency, energy-saving effect, low noise, air distance and other characteristics. Depending on the requirements of the ventilation resistance, the whole machine can be classified either used, thus reducing the ventilation power consumption, energy saving. Tunnel length of 2000 meters may move the fan normal air supply, reducing the labor intensity, saving ventilation time, the local coal mine ventilation is the ideal equipment.

subject: Inquiry about Portable Ventilation Fan for Small Underground Mining - 3x3m Tunnels
Dear Shandong China Coal Sales Team,
I am writing to inquire about your portable ventilation equipment suitable for small-scale underground mining operations.
Our specific requirements are:
Application: Ventilation of small underground mine tunnels (approximately 3 meters wide x 3 meters high) after blasting operations. The goal is to remove blast fumes (CO, NOx, dust) quickly to allow workers to re-enter safely.
Equipment Type: We are interested in two options:
Option A (Gasoline/Petrol): A portable, wheel-mounted centrifugal blower fan. It must be powerful enough to connect to 50-100 meters of flexible ducting (approx. 300-400mm diameter) to extract fumes from the tunnel face.
Option B (Electric - Our priority): We are especially interested in a high-pressure centrifugal blower fan that can be powered by a 48V DC battery bank (via a suitable inverter). If you do not have a ready-made battery-powered model, we are interested in the fan unit alone (without a motor or with a standard 380V AC motor) for us to integrate into our own portable system.
Key Specifications Needed:
Airflow (CFM): Minimum 5,000 - 7,000 CFM.
Static Pressure: High static pressure is critical for use with long ducts (100m). Please specify this value.
Power: Please indicate the power rating (kW/HP) required for the fan to achieve the needed CFM and pressure.
Portability: The unit must be mounted on wheels or be easily transportable.
Our mining operation uses YT27 drilling machines. We need to reduce gas clearance waiting time from 2 hours to 30-40 minutes.
Could you please recommend suitable models from your product range that meet these needs? Please provide:
Technical specifications sheets (datasheets)
Unit pricing (FOB China port)
Lead time for production and shipping
Any available videos of the equipment in operation
Thank you for your time and assistance
