Technical Specifications

Product Features

Compact Forward-Curved Aerodynamics: Engineered with a highly efficient single forward-curved impeller. This specific aerodynamic geometry maximizes volumetric extraction power within a severely restricted physical footprint, making it the premier choice for sleek, concealed appliance architectures.

Charcoal Filter Integration: Uniquely designed with a structural framework that directly supports the installation of active charcoal filters. This capability transforms the motor into a complete recirculating engine, essential for ductless ventilation in modern urban apartments.

Class 180 Thermodynamic Protection: Fortified with industrial-grade Class 180 (Class H) winding insulation. Despite its enclosed and compact operating environment, this thermal management system allows the copper windings to operate safely under intense continuous-duty thermal loads up to 180°C without risk of degradation.

Needle-Flame Resistant Polymer Housing: The compact motor casing is injection-molded from an advanced, lightweight fire-retardant plastic that complies strictly with international needle-flame safety standards, eliminating the risk of combustion propagation within tight appliance enclosures.

Capacitor-Less OEM Architecture: Engineered without an internally mounted capacitor, this configuration provides a highly streamlined electrical interface, granting OEM electrical engineers the flexibility to integrate external capacitance directly onto proprietary appliance PCB switchboards.

Dynamic Variable Speed Control (1 to 8 Stages): Utilizing a highly adaptable single-phase AC configuration, the motor supports a versatile matrix from 1 to 8 distinct RPM speeds, allowing appliance manufacturers to map highly precise, energy-efficient extraction curves tailored to diverse concealed and slide-out models.

Integrated Thermal Overload Shield: Features an in-line thermal protector that continuously monitors internal coil temperatures. In the event of restricted airflow within a tight cabinet or severe ambient heat spikes, the circuit safely interrupts and automatically resets, preventing catastrophic thermal failure.

Applications

The exceptionally compact physical footprint and ductless recirculation capabilities of the K30 Compact Forward-Curved Range Hood Motor make it the definitive choice for:

Concealed & Built-In Range Hoods: Specifically engineered to fit seamlessly inside restricted cabinet spaces, hidden architectural canopies, and specialized slide-out ventilation units.

Ductless / Recirculating Kitchens: The native charcoal filter compatibility is mandatory for high-density urban apartment complexes and condominiums where external exhaust ductwork is structurally prohibited.

Space-Restricted Prosumer Appliances: Delivers high-volume forward-curved suction and Class 180 thermal durability for high-output cooking zones that lack the spatial footprint for traditional bulky metallic blowers.

Agile OEM Appliance Manufacturing: The lightweight polymer chassis and capacitor-less architecture allow for rapid assembly line integration into modern, weight-sensitive kitchen appliances.

Why Choose This Product

For international procurement managers and HVAC engineers, the K30 Compact Forward-Curved Range Hood Motor resolves the critical conflict between spatial limitations and thermodynamic longevity. Standard compact motors frequently suffer from rapid coil burnout due to poor heat dissipation in tight cabinet spaces. By fortifying this compact, high-airflow forward-curved motor with Class 180 insulation and an in-line thermal protector, Electro NASA guarantees that your concealed hoods will survive continuous heavy-duty operation. Furthermore, the built-in charcoal filter support allows OEMs to service the lucrative ductless urban market using a single, highly durable, and easily integrated component.

Installation & Maintenance

Assembly Line Integration for OEMs: This motor is explicitly designed to streamline the manufacturing of concealed and space-restricted appliances. Its highly compact dimensions and lightweight polymer chassis significantly reduce operator fatigue during assembly and allow for effortless integration into tight built-in cabinet geometries. The structural framework natively supports active charcoal filters, allowing manufacturers to quickly adapt a single hood design for both ducted and ductless urban markets on the same assembly line.

Maintenance Profile in Enclosed Applications: Ventilation motors installed in tight, built-in cabinetry are highly susceptible to premature failure due to trapped thermal exhaust and poor heat dissipation. The K30 3111/3112 natively resolves this limitation. Fortified with extreme Class 180 thermal insulation and an auto-resetting in-line thermal protector, the motor operates safely under continuous high-heat loads without requiring physical maintenance. For end-users utilizing the recirculation feature, the motor’s housing is designed for quick, accessible charcoal filter replacements.

FAQ

Why utilize a forward-curved impeller in a compact, concealed range hood motor? In highly restricted physical spaces, generating sufficient suction volume is the primary engineering challenge. A forward-curved impeller is aerodynamically optimized to maximize volumetric air displacement relative to its physical size, ensuring even ultra-sleek, built-in range hoods provide powerful extraction comparable to much larger standard canopies.

How does the built-in charcoal filter compatibility benefit our appliance product line? Urban high-rise developments and condominiums frequently prohibit external exhaust ducting. By integrating structural support for charcoal filters directly onto the motor housing, you can easily offer your concealed hood models as “recirculating” or “ductless” units, instantly expanding your market reach into high-density housing sectors.

Is a plastic motor housing safe to install inside enclosed wooden cabinetry? Absolutely. The K30 3111/3112 casing is injection-molded from an advanced industrial polymer that strictly complies with rigorous international needle-flame testing standards, ensuring complete combustion safety and preventing fire propagation.

Why is Class 180 (Class H) insulation necessary for a compact built-in motor? Built-in and concealed range hoods trap more ambient heat because they are surrounded by cabinetry and lack open-air ventilation. Class 180 insulation allows the motor’s copper windings to safely operate at extreme temperatures up to 180°C, preventing the rapid thermal degradation that frequently plagues standard compact motors in enclosed spaces.

Can the 1-to-8 speed settings be mapped directly to our concealed touch panels? Yes. The motor utilizes a universally adaptable single-phase AC configuration. OEM electrical engineers can seamlessly map the distinct speed taps (from 1 up to 8 stages) to align precisely with proprietary capacitive touch interfaces or hidden slide-out mechanical switches.

What is the international supply capability for this specific compact component?
