High-Temperature Smoke Extraction Motors: Engineered for Maximum Safety

The air intake and smoke extraction motors belonging to the OMS series represent an advanced engineering response to severe thermal environments. Developed by OME Motors' technical team in Italy, these three-phase asynchronous electric motors are customized to drive heavy-duty fans and exhaust systems in modern commercial and industrial structures.

In modern building infrastructure—such as underground parking complexes, commercial shopping centers, transport tunnels, metro stations, and large-scale manufacturing facilities—maintaining air quality and guaranteeing emergency smoke clearance is essential for occupant evacuation and fire safety compliance.

Dual Operational Modes: Continuous Duty vs. Emergency Fire Response

The OMS series motor is engineered to operate seamlessly under two distinct operational paradigms:

  • Normal Conditions (Continuous S1 Duty): Functioning as a standard air intake or exhaust motor, ensuring optimal oxygen exchange, humidity management, and continuous air renewal in enclosed areas.
  • Emergency Fire Conditions (Short-Time S2 Duty): In the event of a fire breakout, the motor automatically switches to emergency extraction mode. It maintains total structural and operational integrity at extreme thermal levels (F300 or F400 classifications), venting toxic fumes, limiting smoke dispersion, clearing escape routes for occupants, and providing fire brigades with critical access window.

Robust Mechanical Architecture & Insulation Integrity

Under high-temperature emergency scenarios, standard industrial electric motors suffer rapid insulation breakdown, bearing failure, and rotor seizure. OME Motors addresses these thermal challenges through specialized mechanical features:

  • High-Temp Insulation Matrix: Utilizing Class H insulation materials combined with specialized synthetic varnishes to prevent winding breakdown under severe heat spikes.
  • Reinforced Bearing Assembly: Equipped with high-temperature synthetic greases and thermal expansion tolerances to ensure continuous shaft rotation during emergency duty cycles.
  • Heavy-Duty Cast Iron & Aluminum Enclosures: Frame constructions optimized for structural stability, corrosion protection, and efficient thermal dissipation.
  • Certified Compliance: Thoroughly tested according to European Standard EN 12101-3, ensuring verifiable reliability under strict international safety codes.

Key Industrial Application Environments

The OMS series smoke extraction electric motors are designed for seamless integration into high-capacity ventilation systems across diverse infrastructure projects:

  • Road, Rail, and Underground Subway Tunnels (Jet Fan and Axial Fan drives)
  • Multilevel Underground Parking Garages
  • Industrial Plants, Chemical Refineries, and Steel Mills
  • Commercial Towers, Shopping Malls, Airport Terminals, and Public Arenas
  • High-Temperature Commercial Kitchen Exhaust & Hood Air Treatment
