FB3G190-1APS-90 Backward Curved Centrifugal Fan, 115VAC, 190mm, 901.3 m3/h

The FB3G190-1APS-90 is a 115VAC backward centrifugal fan engineered to deliver up to 901.3 m3/h (530.4 CFM) of airflow while generating a maximum static pressure of 948 Pa (3.79 in.wg), making it an ideal choice for applications requiring high-pressure performance in compact enclosures. This model integrates a BLDCEC92 motor that operates efficiently across a wide voltage range of 92 to 138VAC, providing plug-and-play compatibility with standard North American and Japanese power outlets without the need for a separate transformer. Its glass-fiber reinforced polypropylene impeller offers exceptional lightweight durability and chemical resistance, while the die-cast aluminum endcap and housing ensure robust mechanical integrity in demanding environments. The fan delivers a rated power of 170W at 4400 RPM, with a noise level of only 74 dB(A), balancing performance and acoustic comfort for commercial HVAC systems, medical equipment, and industrial ventilation. With a 190mm impeller diameter and a rotor diameter of 92mm, this unit is optimized for high static pressure applications such as long duct runs, high-resistance filters, and multi-outlet distribution systems. The fan is protected with Class B insulation and includes a 20AWG cable of 500mm length for straightforward electrical integration. It is available with IP55-rated protection (depending on configuration) and meets CE and RoHS standards, ensuring reliable operation in diverse installations. Choose the FB3G190-1APS-90 for a cost-effective, energy-efficient solution that replaces multiple low-pressure fans with a single high-pressure unit, reducing system complexity and maintenance. FANOVA's meticulous OEM/ODM manufacturing ensures consistent quality and performance for global HVAC and industrial applications.

The FB3G190-1APS-90 represents a specialized 115VAC backward centrifugal fan designed for high static pressure environments, delivering up to 901.3 m3/h of airflow and 948 Pa of static pressure from a compact 190mm impeller. The impeller is precision-molded from glass-fiber reinforced polypropylene (PP+GF), offering a combination of low inertia, corrosion resistance, and lightweight construction that reduces rotor stress and extends bearing life. The blade geometry is backward-curved, optimizing aerodynamic efficiency to achieve a peak static efficiency of over 60% at rated conditions. The fan is driven by a BLDCEC92 motor, a brushless DC motor with integrated EC (Electronically Commutated) control, which provides high energy efficiency (up to 80% at rated load) and a wide operating voltage range from 92VAC to 138VAC, accommodating voltage fluctuations commonly found in North American and Japanese grids. The motor features a permanent-magnet rotor with a diameter of 92mm, enabling a rated speed of 4400 RPM with a power consumption of 170W and a current draw of 2.2A at nominal voltage. Speed control is achieved via a 0-10V analog input or PWM signal (selectable during OEM configuration), allowing precise airflow modulation for demand-based ventilation strategies. The motor incorporates electronic overload protection, reverse polarity protection, and soft-start functionality, while the stator winding is insulated to Class B (130°C) standards, ensuring safe operation under elevated temperatures. The fan housing and endcap are constructed from die-cast aluminum alloy, providing excellent heat dissipation and mechanical rigidity, with a corrosion-resistant surface treatment that withstands industrial atmospheres. The rotor shaft is supported by dual ball bearings rated for 50,000 hours of operation at 40°C, ensuring long-term reliability in continuous-duty applications. Electrical connectivity is provided through a 20AWG lead wire of 500mm length, terminated with bare wires or optional connectors for streamlined installation. The fan is available in IP55-rated configurations for protection against dust and water jets, making it suitable for outdoor or wash-down environments. The FB3G190-1APS-90 complies with CE, RoHS, and UL (optional) certifications, and is manufactured under ISO9001 quality management systems. Its ability to generate high static pressure enables it to overcome the resistance of long ductwork, high-efficiency filters (e.g., HEPA pre-filters), and complex air distribution manifolds, positioning it as a superior alternative to multiple fans in parallel, thus reducing system footprint and installation cost. Ideal for HVAC air handling units, precision cooling systems, cleanroom equipment, and industrial process ventilation, this model combines high performance with energy-saving EC motor technology, making it a future-proof choice for OEMs seeking to enhance product efficiency and reliability.

DC Backward Curved Centrifugal Fan
Type	FB3G190-1APS-90
Model	BLDCEC92

Ⅰ.When taking out the fan, do not directly lift the fan lead wire. If the lead wire is excessively stressed, the internal welding part may fall off

Ⅱ.Do not plug or unplug the fan lead plug when the fan is running

Ⅲ.If the fan does not work after starting, do not touch the impeller, rotor, or other parts, professional technical personnel are required to inspect the fan to prevent sudden start of the fan from causing hand or other personal injury

Ⅳ.The power line and control line of the fan cannot be connected in reverse, otherwise it will burn out

Ⅴ.Because of the soft start characteristics of the fan, to prevent personal injury, do not touch the impeller or other parts of the fan during powered on or running at low speeds

Ⅵ.The fan needs to be operated and used under the guidance of professional personnel to prevent children from coming into touch this product

Ⅶ.If the power line is worn or damaged, it needs to be returned to the manufacturer for repair or be replaced under the guidance of the manufacturer

Ⅷ.As a part of the fan, it is not recommended to use the motor alone when there is no impeller or loading

1. High Efficiency: The FB3G190-1APS-90 delivers 901.3 m3/h at 948 Pa while drawing only 170W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 190mm galvanized steel sheet impeller resists corrosion, wear and high temperatures, making the fan suitable for harsh industrial environments and corrosive gas streams.

3. Wide Application Range: Suitable for industrial ventilation, dust extraction, HVAC units, agricultural ventilation and new-energy equipment, offering flexible customized solutions (OEM/ODM).
