FD3G180-2AGL-20 Dual Inlet Centrifugal Blower, 230VAC, 180mm, 2040 m3/h

This dual inlet centrifugal blower is engineered for high-demand ventilation systems where both substantial airflow and elevated static pressure are non-negotiable. The FD3G180-2AGL-20 delivers a maximum airflow of 2040 m³/h (1200.5 CFM) and a static pressure of 840 Pa (3.36 in.wg), making it a formidable single-unit replacement for multiple smaller fans in ducted networks. Equipped with a 230VAC EC motor (BLDCEC102) that operates across a wide 184–270V range, this model provides true plug-and-play compatibility for retrofit projects upgrading from AC technology. The motor draws a nominal current of 1.5A at 1450 RPM, consuming 350W to achieve an efficiency that significantly lowers operational costs compared to conventional induction motors. Built with a galvanized steel sheet impeller (180mm diameter) and a die-cast aluminum housing, the blower offers superior corrosion resistance and mechanical robustness for industrial environments. It features variable speed control capability, allowing precise adjustment of airflow to match real-time system demands, which enhances energy savings and occupant comfort. The unit's noise level is rated at 73.2 dB(A), a reasonable output given its powerful performance, and it is well-suited for HVAC air handling units, cleanroom pressurization, and process ventilation. The blower is protected with standard IP rating and thermal overload safeguards, while its high-quality ball bearings ensure a long service life under continuous operation. FANOVA's FD3G180-2AGL-20 is your heavy-duty solution for achieving high airflow and pressure in a single, compact footprint.

The FD3G180-2AGL-20 is a dual inlet centrifugal blower designed for high-pressure, high-volume air movement in demanding HVAC and industrial applications. Its impeller is constructed from galvanized steel sheet (SPCC), featuring a forward-curved blade design with a 180mm diameter. The galvanized coating provides excellent resistance to atmospheric corrosion and minor chemical exposure, making it suitable for semi-harsh environments without sacrificing structural integrity. The blade geometry is optimized to maximize air movement at lower rotational speeds, reducing bearing wear and acoustic noise while maintaining high static pressure capability. The blower housing is made of die-cast aluminum alloy (ADC12), offering a lightweight yet rigid frame that maintains precise clearance between the impeller and the casing, ensuring aerodynamic efficiency and minimal leakage. The motor is a brushless DC (BLDC) EC type, model BLDCEC102, with an external rotor design integrated into the housing. This motor operates on 230VAC input (single phase) and can tolerate a supply voltage range of 184VAC to 270VAC, ensuring stable performance even in facilities with fluctuating grid power. The motor's rated input power is 350W, drawing a current of 1.5A at the nominal speed of 1450 RPM. The EC design incorporates a built-in inverter that converts AC to DC, achieving efficiency levels above 85% across the operating range, significantly reducing energy consumption compared to standard AC motors of similar output. Speed control is achieved via a 0-10VDC analog signal input or an optional PWM (pulse width modulation) interface, allowing seamless integration with building management systems (BMS) or standalone controllers. This enables precise modulation of airflow from 0% to 100% capacity, optimizing performance for variable air volume (VAV) systems. The motor's electronic control unit includes protection features such as overcurrent, overvoltage, undervoltage, and thermal overload detection, which automatically shuts down the motor to prevent damage. The insulation system is Class F (155°C), and the motor is rated for continuous duty (S1). The blower uses two sealed ball bearings (deep groove type) that are maintenance-free and lubricated for life, providing a rated service life of over 30,000 hours at typical operating temperatures. The electrical interface is a 500mm long 18AWG cable that provides power, ground, and signal connections, with tinned copper strands for superior conductivity and corrosion resistance. The entire assembly is balanced to ISO 1940 G2.5 grade, ensuring smooth, vibration-free operation. The blower's maximum static pressure is 840 Pa (3.36 in.wg) at zero flow, and its maximum airflow is 2040 m³/h (1200.5 CFM) at free air conditions, with the operating point typically between these extremes. The acoustic noise output is 73.2 dB(A) measured at 1 meter distance in a semi-anechoic chamber, which is acceptable for industrial spaces. The blower is manufactured under ISO 9001 quality management system, and the motor complies with CE, RoHS, and UL requirements where applicable. All metallic parts are treated to prevent rust, and the paint or coating (if any) is resistant to chipping. The unit is designed for either horizontal or vertical mounting, with inlet rings that accommodate standard duct connections. This robust construction makes the FD3G180-2AGL-20 ideal for use in air handling units, heat recovery ventilators, fume exhaust systems, and high-resistance filter applications, providing reliable, energy-efficient performance over a long lifespan.

AC Dual Inlet Centrifugal Blower

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
