BMJ / GD30K2-12 / T30 / T35 / T40 / BT35 / BFT35
Industrial Ventilation & Gas Booster Fans
BMJ / GD30K2-12 / T30 / T35 / T40 / BT35 / BFT35: The industrial fan range covers BMJ gas boosters, GD30K2-12 fans for pneumatic conveying, T-series general ventilation fans and BT35/BFT35 configurations for specified gas duties. Materials and motor configuration must match the conveyed medium.
BMJ series shown. Other series differ in construction.
Built around your working task.
Review the model and technical reference together with your application requirements. Provide airflow, pressure, conveyed medium, temperature and duct arrangement. Identify any special material, motor or certification requirement.
BMJ series
Gas-booster series; the documented outlet positions are 0°, 90° and 180°. Confirm the gas duty and sealing arrangement.
GD30K2-12 series
The document states a maximum medium temperature of 80°C and maximum particle concentration of 150 mg/m³. Confirm the conveying duty.
T30 series
Request the duty-specific selection sheet for this series.
T35 series
The documented maximum gas temperature is 40°C. Confirm the general ventilation duty.
T40 series
Request the duty-specific selection sheet for this series.
BT35 series
The documented maximum gas temperature is 40°C. Confirm the specific gas duty and required configuration.
BFT35 series
The documented maximum gas temperature is 60°C. Confirm material and motor requirements for the specific duty.
Technical specifications
Values are series-specific. Confirm the exact series, duty and motor configuration before selection. Any explosion-protected application requires configuration and certificate confirmation; brochure descriptions are not a current certificate.

Check the operating conditions.
Provide airflow, pressure, conveyed medium, temperature and duct arrangement. Identify any special material, motor or certification requirement.
Check the current technical sheet against the configuration in the quotation. Dimensions, interfaces and operating requirements should be confirmed before planning the installation.
Separate gas boosting from general ventilation
The industrial fan range brings together different applications: BMJ gas boosting, GD30K2-12 pneumatic conveying and high-pressure forced ventilation, and T30, T35 and T40 general ventilation. Start with the conveyed medium and process duty rather than choosing from an overall fan-family name.
The T-series source describes ventilation and heat dissipation in factories, warehouses, offices and buildings. That use should not be confused with gas boosting or mine-atmosphere suitability. The industrial catalogue is separate from the mining ventilation fan selection.
BMJ and conveying-fan construction
The BMJ source describes a welded casing and base with an airflow-seal arrangement. Its impeller material is specified as stainless or alloy steel according to the duty. The casing includes an upper steam-pipe interface and a lower drain connection. These are BMJ details, not standard features claimed for every series here.
GD30K2-12 is described for pneumatic conveying and high-pressure forced ventilation. Its standard gas duty is non-sticky and non-corrosive to metal, within the documented temperature and particle limits. A corrosive medium requires a separately selected material configuration; it should not be assumed acceptable to the standard arrangement.
Specify the medium before selecting materials and motors
Provide the gas composition, temperature, particle concentration, required airflow and pressure. Add the inlet and outlet arrangement and installation space. For BMJ, outlet angles and rotation direction are configuration items to agree with the proposed layout.
The listed 40°C reference applies to T35 and BT35, while BFT35 has a separate 60°C reference. Keep the selected series and its limits together. Any required explosion-protection documentation must match the offered fan and motor; the source brochure does not verify current certification for a particular order.
Selection questions
What should I include in a product inquiry?
Provide airflow, pressure, conveyed medium, temperature and duct arrangement. Identify any special material, motor or certification requirement.
Which technical details need confirmation?
Values are series-specific. Confirm the exact series, duty and motor configuration before selection. Any explosion-protected application requires configuration and certificate confirmation; brochure descriptions are not a current certificate.
How do I request the selected configuration?
Send the model or series reference and your project requirements through the inquiry link. Include drawings or the existing equipment reference where available.
Are all listed fan series suitable for the same gas temperature?
No. Temperature and medium restrictions are series-specific. For example, the source gives different references for T35/BT35 and BFT35. Select the complete series configuration against the actual conveyed medium.
