The Y6-30 boiler induced draft fan is designed for extracting boiler flue gas and maintaining stable negative pressure in industrial boiler systems. It can be supplied with C-type or D-type drive, left-hand or right-hand rotation, and multiple outlet-angle arrangements.
The fan is mainly composed of the impeller, casing, air inlet, air-regulating damper and transmission assembly. Available fan sizes, motor power, speed, airflow and total pressure should be selected according to the actual boiler capacity and system resistance.
Qiyue Fan can configure the motor voltage, drive arrangement, rotation direction, outlet angle, surface treatment and material according to the operating temperature, gas composition, dust concentration and installation requirements. Stainless-steel or corrosion-resistant configurations are available subject to project confirmation.
Designed for boiler induced-draft systems that require stable flue-gas extraction, controlled negative pressure and flexible installation arrangements.

Product Overview
A Configurable Boiler Induced Draft Fan for Stable System Draft
The Y6-30 boiler induced draft fan is used to extract combustion flue gas and maintain the negative pressure required by the boiler system. It can be selected for small and medium boiler installations according to the required airflow, total pressure, boiler capacity and site layout.
The series is available with C-type or D-type drive. Rotation direction, outlet angle, motor specification and material can be configured according to the project. Final selection should be based on the actual system resistance, gas temperature, gas composition and expected operating point.
Typical Selection Inputs
Required airflow at operating condition
Required total pressure and system resistance
Flue-gas temperature and dust concentration
Motor voltage, frequency and protection level
Rotation direction and outlet angle
Drive, Rotation and Outlet Arrangement
C-Type Drive
The impeller is driven through a belt transmission. This arrangement supports speed matching and is suitable where flexible motor positioning is required.
D-Type Drive
The impeller is directly connected to the motor shaft. The applicable model and motor configuration should be confirmed for the project.
Outlet Direction
Standard 0° outlet is available. Required configurations may include 45°, 90°, 135°, 180° and 225° for left-hand or right-hand rotation.
Main Components and Working Structure
Impeller
The impeller consists of multiple blades, a curved front plate and a flat rear plate. It converts mechanical energy into airflow and pressure.
Casing
The volute casing collects the gas discharged from the impeller and guides it toward the outlet while reducing unnecessary flow loss.
Air Inlet
The inlet directs flue gas smoothly into the impeller eye and helps maintain stable inlet flow conditions.
Air-Regulating Damper
The damper supports operating adjustment during commissioning and can help match the actual system resistance.
Transmission Assembly
The drive assembly includes the shaft, bearing components, coupling or belt components according to the selected arrangement.
Motor and Base
The motor and structural base are selected to match fan size, speed, power and installation requirements.
Application Range
Typical Boiler and Flue-Gas Applications
Industrial steam boilers
Hot-water boiler systems
Biomass boiler exhaust
Coal-fired boiler draft
Flue-gas extraction
Dust-removal system exhaust
Furnace negative-pressure control
Process exhaust systems
Material and Project Configuration
Standard Configuration
The standard material and surface treatment should be selected according to flue-gas temperature, dust loading and corrosion conditions. Motor, bearing, guard and base configuration are matched to the selected fan size.
Optional Customization
Available project options may include stainless-steel components, corrosion-resistant coating, high-temperature configuration, customized motor voltage, vibration isolation and non-standard outlet arrangement, subject to factory confirmation.

How to Select the Correct Y6-30 Fan
1. Confirm the Operating Point
Provide design airflow and total pressure after considering duct resistance, equipment resistance and required reserve.
2. Confirm the Medium
State gas temperature, dust concentration, moisture and corrosive components so the material and bearing arrangement can be checked.
3. Confirm Installation
Specify C-type or D-type drive, motor requirements, rotation direction, outlet angle, base arrangement and available installation space.
Quality Control and Delivery
Impeller dimensional inspection
Dynamic balance verification
Rotation and vibration check
Motor and guard inspection
Surface and coating inspection
Nameplate and direction marking
Export packing confirmation
Document and accessory check
Frequently Asked Questions
What information is required to select a Y6-30 boiler induced draft fan?
Please provide airflow, total pressure, gas temperature, gas composition, dust concentration, motor voltage, installation space, rotation direction and outlet angle.
Can the Y6-30 fan be supplied in left-hand and right-hand rotation?
Yes. Rotation is determined when viewed from the motor side and should be confirmed together with the required outlet angle.
Which outlet angles are available?
The standard outlet is 0°. Other arrangements such as 45°, 90°, 135°, 180° and 225° can be considered according to installation requirements.
Can the motor voltage and frequency be customized?
Yes. Motor voltage, frequency, protection level and insulation class can be matched to the destination market and operating environment.
Is stainless-steel construction available?
Stainless-steel components or other corrosion-resistant configurations can be evaluated according to the medium and project requirements.
