Before RFQ

Selection factors the CBF Explosion-proof Axial Fan

Model review: Compare the published CBF-300, CBF-400, CBF-500, CBF-600, CBF-700 and CBF-750 rows above, then confirm hazardous-area requirements and document scope for the selected model.

  • 1Confirm the hazardous-area classification: the project hazardous-area classification, gas group, temperature class and whether dust protection is required.
  • 2Confirm the installation form: fixed wall/panel type, duct-connected type or portable temporary ventilation type.
  • 3Confirm required airflow, static pressure allowance, duct length, number of bends and outlet resistance.
  • 4Confirm voltage, frequency, grounding, cable routing and whether local electrical accessories must also be explosion-proof rated.
  • 5Confirm the target market document package. CE, ATEX and IECEx status must be checked for export projects; do not rely on domestic certificates alone.

Compare CBF with Other Linggong Fan Options Only After Fit Is Narrowed

Use Table 3 only after the CBF fit window is narrowed. This comparison helps you check whether another Linggong fan family is better matched to the installation route or non-hazardous application.
Related fan option comparison
Product / Series Best For Selection Difference
CBF Explosion-proof Axial Fan Hazardous-area exhaust and supply ventilation Use when explosion-proof marking and hazardous-area installation are required.
SF Axial Fan General axial ventilation Use only for non-hazardous areas where explosion-proof construction is not required.
DPT Duct Fan Ducted fresh air and exhaust systems Better for duct routing and quiet indoor ventilation, not for hazardous gas areas.
HF Oblique-flow Duct Fan Inline booster airflow Use for pressure-assisted duct ventilation in non-explosion-proof applications.
If Table 3 suggests another fan family may fit better, keep the same quote route and send airflow target, installation route, hazardous-area classification and voltage for model confirmation for final selection.
Safety basis

Explosion-proof Rating and Safety Notes

How to read this table: Treat safety markings and certificates as confirmation items. Do not use this table as a substitute for project approval documents.
Explosion-proof rating and safety confirmation items
Position Available / stated value Engineering meaning
Hazardous area Classified hazardous-area ventilation; confirm gas/dust group and local site classification before use For locations where explosive gas atmosphere may occur during normal or abnormal conditions.
Explosion-proof mark Ex db ⅡB T4 Gb; Ex db ⅡC T4 Gb; Ex tb ⅢC T130℃ Db Confirm final marking against the ordered motor nameplate and project specification before use.
Protection level Inlet safety guard IP20; outlet safety guard IP10; matched explosion-proof motor IP65 Suitable for many industrial environments, but not a substitute for corrosion-proof or outdoor weatherproof design.

Installation limits

  • Do not use this product where the required gas group, temperature class or dust zone exceeds the confirmed nameplate marking.
  • Do not replace explosion-proof cable glands, junction boxes or motors with ordinary electrical parts.
  • Do not use as a smoke exhaust fan for high-temperature fire conditions unless a fire-rated model is specified.
  • For corrosive gas, outdoor exposure or marine environments, confirm anti-corrosion material and coating requirements before order.
Selection steps

How to Select a CBF Explosion-proof Axial Fan

  1. Confirm hazardous classification: the project hazardous-area classification, gas group, temperature class and dust requirement.
  2. Estimate required airflow: Room volume × required air changes per hour. Hazardous process areas often need higher air-change rates based on local safety rules.
  3. Check installation resistance: Wall mounting, duct length, bends and outlet louvers all reduce actual airflow.
  4. Match voltage and wiring: Confirm 220V single-phase or 380V three-phase according to site power supply.
  5. Verify certificates: Ask for the applicable explosion-proof certificate and export-market documents before project approval.

If you are replacing an existing fan, send us the old model, blade diameter, voltage, power, installation photo and hazardous-area requirement. We can help check the closest CBF replacement size.

Fit limits

When CBF Series May NOT Be the Right Choice

  • You need certified smoke exhaust performance for fire conditions.
  • The project requires ATEX or IECEx documents immediately and the certificate status has not been confirmed.
  • The duct system has high static pressure; a centrifugal or mixed-flow fan may be more suitable.
  • The site has strong corrosive gas, salt spray or outdoor weather exposure without anti-corrosion customization.
  • You need precise low-noise comfort ventilation rather than industrial hazardous-area exhaust.
Application areas

Typical Applications

  • Chemical production and storage areas
  • Oil and gas auxiliary workshops
  • Paint booths, coating rooms and solvent storage areas
  • Battery, electronics or material-processing rooms with hazardous ventilation needs
  • Grain depots and combustible-dust-related industrial areas, subject to final dust-zone confirmation

Häufig gestellte Fragen

Can the CBF fan be used in classified hazardous areas?

The CBF page provides explosion-proof axial fan information for hazardous-area ventilation projects. Final suitability must be confirmed against the exact Ex marking, gas group, temperature class, certificate documents and local site classification before use.

Which CBF model should I choose?

Start with required airflow, installation type and power supply. Compare the CBF-300 to CBF-750 model range, then confirm voltage, duct resistance, mounting form and document requirements before requesting model confirmation.

What installation forms are available for the CBF series?

The page separates fixed front/rear duct connection, inline duct type and mobile four-foot portable type. Fixed and duct forms require duct or interface confirmation; mobile workstation use does not require duct connection.

What should I send before model confirmation?

Send the target airflow, installation form, voltage and frequency, hazardous-area classification, gas group or dust condition if known, mounting location, quantity and destination. If the site classification is still under review, send the current project description first so the model and document scope can be checked for quote review.

Are ATEX or IECEx documents available for this CBF page?

This page shows the current domestic explosion-proof certificate and inspection report scope. Do not assume ATEX, IECEx or other overseas explosion-proof approval unless those documents are separately provided and verified for the exact model and project requirement.

What happens after I send the fit-check package?

Linggongshare reviews the airflow target, installation form, voltage, hazardous-area notes, destination and quantity first. If the project details are enough, the team can narrow the model and document scope for quote review; if site classification is incomplete, the reply will list the missing confirmation items.

If these answers match your project conditions, move to the fit-check package below so the model and document scope can be confirmed for quote review.
