WEG Flameproof Motors Ex DB
WEG Flameproof Ex DB Motor Supply & Service — Australia
MNP Electrical supplies the complete WEG Flameproof Ex db motor range across Australia. WEG’s flameproof range is purpose-built for environments where standard motors cannot safely operate — oil refineries, gas processing plants, chemical facilities, mining operations, and any site where flammable gases or explosive atmospheres may be present.
The WEG flameproof lineup covers every scale of application — from compact low voltage motors for pumps and fans, through the heavy-duty Master and W60 lines for demanding classified area projects, up to large MV/HV motors for major industrial drives. Every motor in the range carries IECEx and ANZEx certification, meeting Australian standards for classified area electrical equipment.
Contact MNP Electrical with your requirements for an Electric Motor and we’ll identify the right model and supply it anywhere across Australia, complete with full certification documentation.
WEG Flameproof Ex DB Motor Product Range
WEG manufactures flameproof Ex db motors across four distinct product lines — each designed for different application scales and environmental requirements.
Ex db
Low Voltage Flameproof Motors
The W22Xdb low voltage flameproof motor is WEG’s most widely specified classified area product. Built on the proven W22 platform with a precision-engineered cast iron enclosure, it contains any internal ignition and prevents it reaching the surrounding atmosphere. Available in single phase and three phase, suitable for Zone 1 and Zone 2 gas environments.
- 0.12 – 370 kW
- IEC 71 – 355
- Zone 1 & 2
- Groups IIA / IIB / IIC
- IE2
- IECEx / ANZEx
Ex db — Heavy Duty
Master (Classified Area)
The Master line motors are calculated and designed to meet the most diverse applications in explosive atmospheres. With specific safety features, they guarantee the safety of the plant where equipment with standard features cannot be used. The Master range handles demanding classified area applications where the standard W22Xdb platform reaches its limits.
- High Power Range
- Explosive Atmospheres
- Zone 1 & 2
- IECEx Certified
- Custom Engineering
Ex db — Large Frame
W60 (Classified Area)
The W60 line motors are calculated and designed to meet the most diverse applications in explosive atmospheres. Built for large-scale classified area installations, the W60 platform delivers the power and robustness required for major industrial drives — compressors, large fans, and pump systems — where standard low voltage frames are insufficient.
- Large Frame
- High Output
- Explosive Atmospheres
- Zone 1 & 2
