People Electric · Explosion-Proof Axial Fan
Product overview
People Electric BT35 is an explosion-proof axial-fan family with documented fan numbers 2.8–7.1 and four mounting forms. Fan number, rotation-speed entry and impeller angle identify a particular performance row; airflow, pressure, motor power and noise must be read together from that row. The speed selector is limited to the speeds actually listed for the chosen fan number.
Technical selection summary
| Manufacturer / family | Original People Electric BT35 |
|---|---|
| Rated supply | AC 220V or AC 380V; confirm motor phase and frequency for the exact supplied version |

| BT35-4.5 | Impeller diameter entry 450; documented rotation-speed entries 1450 |
| BT35-5 | Impeller diameter entry 500; documented rotation-speed entries 1450, 960 |
| BT35-5.6 | Impeller diameter entry 560; documented rotation-speed entries 1450, 960 |
| BT35-6.3 | Impeller diameter entry 630; documented rotation-speed entries 1450, 960 |
| BT35-7.1 | Impeller diameter entry 710; documented rotation-speed entries 1450, 960 |
| Impeller-angle entries | 15, 20, 25, 30 or 35 in each documented performance group |
| Mounting codes | I: wall (omissible in code); II: bracket; III: fixed; IV: pipe |
| Manufacturer Ex marking | Exd IIB T4 Gb as printed in the catalogue. Confirm current nameplate and applicable documentation for the supplied unit. |
| Manufacturer application scope | Zone 1/2; gas groups IIA/IIB; temperature classes T1–T4; match actual gas and ambient conditions |
| Standards referenced | GB 3836.1, GB 3836.2 and IEC 60079; this page does not assert an unobserved certificate |
| Cable entry | G3/4 thread; cable outside diameter 9–14mm |
| Performance / units | The original operating-point tables contain airflow, pressure, power and noise for each fan-number/speed/angle row. The English table omits several units; request a factory-confirmed duty schedule rather than assuming units or combining values from different rows. |
| Outline | Model-specific L/diameter dimensions and all four mounting sketches are retained in the technical images and complete PDF. Confirm final dimensions and motor envelope. |
Use the speed and angle from one original performance row. Supply voltage, mounting and operating-point selections are enquiry requirements; final motor, phase/frequency, power, airflow/static-pressure duty and complete order suffix require factory confirmation. Verify hazardous-area classification, actual Ex marking, ambient limits and required conformity documentation for the installation.
Typical applications
- Industrial ventilation in locations within the manufacturer-stated hazardous-gas scope.
- Wall, bracket, fixed or duct/pipe-mounted ventilation with a matched airflow and pressure duty.
