K30 electric motor

K30 Series Exhaust Fan Motors

The K30 electric motor is a reliable and widely used motor in the kitchen hood industry. It features a copper-wire starter and is available in various speed configurations, with plastic or metal housings, bidirectional rotation, and a built-in thermal protector on every unit. With its cost-effective design, reliable durability, and good resistance to overheating, the K30 remains a practical and widely used choice for kitchen hood applications — and one of the reasons Electro NASA became the first manufacturer of kitchen hood electric motors in Iran.

Why the K30 Platform Still Leads the Market

Proven, cost-effective design. Given its age and original design approach, the K30 offers an affordable price point while maintaining good resistance to burnout — the reason it remains the top choice for so many hood manufacturers building mid-tier, high-volume product lines.

Copper-wire winding. Unlike manufacturers that substitute copper-clad aluminum (CCA) to cut costs, Electro NASA builds every K30 motor with pure copper winding for superior conductivity, better thermal resistance, and a longer service life.

Thermal protection on every unit. All K30 motors are equipped with a thermal protector (Thermoguard) to prevent overheating and fire risk — a non-negotiable safety component, not an optional upgrade.

Bidirectional rotation. CW and CCW availability gives your design engineers freedom to match the motor to your volute’s airflow direction without constraint.

The Three K30 Models

K30 Plastic Cover (1115/1111) — Backward-Curved

The standard K30 configuration: a flame-retardant plastic housing with a backward-curved impeller optimized for high static pressure — the right choice when your hood design routes through a long or restrictive exhaust duct. Suitable for a wide range of kitchen hood models.

• Housing Material: Flame-Retardant Plastic (needle-flame test certified)
• Impeller Type: Backward-Curved, single impeller
• Insulation Class: 180

K30 Metal Cover (1117/1113) — Backward-Curved

The same backward-curved aerodynamic profile, built into a durable and stylish galvanized steel housing with precision assembly — the choice for buyers who need the structural durability and long service life of a metal chassis alongside high-static-pressure performance.

• Housing Material: Galvanized Steel (precision assembly)
• Impeller Type: Backward-Curved, single impeller
• Insulation Class: 180

K30 Plastic Cover (3112/3111) — Compact, Forward-Curved

A compact-design plastic motor built for high airflow in a small footprint, compatible with concealed and specialty hood models and with carbon filters — the right fit for ductless, recirculating installations where external venting isn’t available.

• Housing Material: Flame-Retardant Plastic (precision assembly)
• Impeller Type: Forward-Curved, single impeller
• Compatible with carbon filters
• Insulation Class: 180

Applications

High-volume, mid-tier residential hoods where proven reliability and cost control matter more than premium acoustic performance.

Long or restrictive duct runs — the plastic and metal backward-curved models (1111/1115, 1113/1117) resist stalling under high static pressure.

Concealed and ductless installations — the compact forward-curved model (3111/3112) is purpose-built for carbon-filter recirculating hoods.

Export markets requiring 50/60 Hz flexibility — every K30 model runs on both frequencies without redesign.
