Description

D Series Mixed-Flow Boost Inline Duct Fan

D series mixed-flow inline duct fan adopts axial-centrifugal mixed-flow impeller structure, full plastic sealed cylindrical body, 220V single-phase household power supply. It has 5 pipe diameter specifications (100/150/200/250/315mm), each with dual power (low/high speed) options, featuring large airflow, high static pressure and easy disassembly, widely used for ventilation, dehumidification and odor removal in bathrooms, supermarkets, hotels and entertainment venues.

Core Product Features

Structural & Performance Advantages

· Mixed-Flow Boost Impeller Design: Combines the high airflow of axial fans and high static pressure of centrifugal fans, strong long-distance pipeline air supply capacity, high ventilation efficiency and low energy consumption.

· High-Quality Double-Speed Silent Motor: Dual-speed wind adjustment (low speed / high speed), precision bearings for stable long-time operation, low running noise.

· Full Plastic Integrated Cylindrical Body: Tight sealing structure to prevent air leakage, corrosion-resistant, moisture-proof, lightweight and easy handling.

· Quick Disassembly Integrated Structure: Buckle connection between motor section and duct cylinder, convenient to take out the motor and impeller for dust cleaning and maintenance without removing the whole pipeline.

· Standard reserved long mounting holes for ceiling concealed hoisting, matching circular ventilation pipes of corresponding calibers, simple pipeline docking.

Working Principle

Mixed-flow impeller rotates to generate boost airflow; outdoor fresh air can be pressurized and sent indoors for positive-pressure fresh air supply, or indoor turbid humid air can be extracted and exhausted outdoors for negative-pressure deodorization & dehumidification, dual-purpose for air supply and exhaust.

Typical Application Scenarios

· Civil: Household bathrooms, toilets, storage rooms, cloakrooms

· Commercial: Hotel guest rooms, supermarket restrooms, internet cafes, small catering shops, KTV entertainment rooms

· Matching demand: Circular pipeline ventilation projects, small-space dehumidification & odor removal, quiet low-noise rest environments

Usage Restrictions

· Power supply: Standard 220V 50Hz single-phase AC, compatible with ordinary household wall sockets.

· Installation: Concealed ceiling hoisting is recommended; install horizontally or vertically, keep the pipeline smooth without sharp bends to avoid airflow attenuation.

· Operating ambient temperature: -10℃ ~ 45℃; avoid long-term direct contact with high-temperature hot steam.

· Maintenance cycle: Disassemble and clean dust and lint on the impeller every 3–6 months to prevent noise rise and airflow drop.

Q1: What is the advantage of mixed-flow impeller compared with ordinary axial duct fans?
A1: Mixed-flow structure balances large airflow and high static pressure, can support longer and more complex branch pipelines; ordinary axial fans have low static pressure and are only suitable for short straight pipes.
Q2: Does each model support dual-speed adjustment? What are the applicable scenarios for two gears?
A2: Every model has low-speed and high-speed power versions. Low speed for daily mild ventilation; high speed for rapid dehumidification and odor removal after shower or crowded commercial periods.
Q3: What material is the fan body made of? Is it suitable for long-term humid bathroom environments?
A3: Full integrated plastic cylinder, good moisture-proof and anti-corrosion performance, will not rust like metal fans in high-humidity spaces such as bathrooms.
Q4: What power supply standard does D series adopt? Is it suitable for household and hotel engineering?
A4: Standard 220V 50Hz single-phase household electricity, directly matched with common socket circuits, widely used in residential renovation and hotel bathroom ventilation projects.
Q5: Can this fan be used as both fresh air supply and exhaust fan?
A5: Yes, it is dual-purpose: install at the air intake end to deliver purified fresh air indoors; install at the exhaust end to extract turbid air outdoors.
Q6: Is daily disassembly and maintenance convenient?
A6: Buckle quick-release design between motor module and duct cylinder, no need to remove the whole pipeline, directly take out the motor and impeller for dust cleaning, low maintenance difficulty.
Q7: What installation ways are supported? Does it require large ceiling space?
A7: Horizontal and vertical installation are both available, compact cylindrical body, suitable for narrow ceiling interlayer space, reserved long mounting holes for fixed hoisting.
Q8: What is the noise performance of the unit? Will it disturb sleep in hotel rooms?
A8: Optimized mute air duct + silent bearing motor, the minimum noise is only 25dB under low-speed mode, soft running sound, will not interfere with rest.
Q9: Can we customize special voltage such as 110V/60Hz for export bulk orders?
A9: Standard configuration is 220V 50Hz single-phase power supply. We support customized dual-speed silent motors matching 110V 60Hz grid standards for large export container orders.
Q10: What supporting documents and spare parts are provided for wholesale bulk purchases?
A10: Each unit is attached with full English installation and operation manual. Complete spare parts include dual-speed motors, non-return valves and hoisting accessories; we also provide circular pipeline layout technical guidance for ventilation engineering.
