Efficient Air Conveying

Designed to move dust-laden air efficiently through industrial exhaust and duct systems.

The LWFDF6-48 utilizes an optimized aerodynamic profile to generate high-velocity suction capable of moving heavy volumes of air mixed with non-corrosive particulates. It ensures continuous extraction of factory dust, airborne fibers, and process heat directly from the source.

Efficient Dust Extraction — captures particulate-laden air quickly and effectively
Stable Air Delivery — ensures consistent volumetric flow under load
High Throughput — achieves up to 79,111 m³/h for massive plant requirements

Efficient Air Conveying - LWFDF6-48 Centrifugal Fan

Low Vibration & Stable Operation

A balanced impeller and reinforced structure help reduce vibration for smooth, dependable performance.

Every rotating assembly undergoes strict static and dynamic balancing during manufacturing. This precision tuning, combined with a heavy-duty steel base, mitigates operational resonance, preventing premature bearing failure and keeping noise levels within acceptable industrial limits.

Balanced Rotating Assembly — prevents mechanical shaking and bearing wear
Reinforced Support Structure — absorbs and dampens motor vibrations
Smooth Continuous Operation — maintains steady output across 24/7 shifts

Low Vibration and Stable Operation of LWFDF6-48 Fan

Reliable Drive For Continuous Operation

The motor and drive system are selected to match operating requirements, providing dependable power for industrial exhaust applications.

Fitted with high-efficiency copper-wound industrial motors, the LWFDF6-48 guarantees thermal stability under continuous heavy loads. In the belt-drive configurations, premium tensioned V-belts and cast-iron pulleys ensure slip-free torque transfer and allow for precise speed optimization.

Dependable Power — motors ranging from 0.55 kW to 75 kW to match specific loads
Stable Transmission — heavy-duty belts and precision-machined pulleys
Built for Continuous Duty — S1 rated for uninterrupted factory operation

Reliable Belt Drive for Continuous Operation

Engineered for Dust-laden Air

The centrifugal airflow structure supports efficient conveying of dust, wood scraps, and fine fibers.

Traditional multi-vane blowers clog quickly when exposed to debris. The LWFDF6-48 utilizes a robust open-blade impeller specifically engineered to minimize material adhesion. This wear-resistant design allows heavy wood chips, textile fluff, and industrial particulates to pass through the scroll casing without restricting airflow or unbalancing the wheel.

Efficient Air Movement — maintains strong suction velocity for particulate capture
Reduced Material Adhesion — specialized blade pitch prevents fiber and dust buildup
Wear-resistant Design — withstands the continuous abrasion of conveyed scraps

Wear-Resistant Impeller Engineered for Dust-laden Air

Two Drive Configurations

Choose the drive arrangement that best matches your installation space and operating requirements.

The Type A (Direct Drive) mounts the impeller directly to the motor shaft, resulting in a highly compact, maintenance-free footprint ideal for tight spaces. The Type C (Belt Drive) isolates the motor from the main housing, protecting it from potential heat and offering the flexibility to adjust the fan's RPM via pulley changes.

Type A | Direct Drive — compact structure, simple transmission, space-saving
Type C | Belt Drive — separate motor arrangement, adaptable transmission setup
Flexible Selection — tailored to specific industrial layout constraints

Two Drive Configurations: Type A Direct Drive and Type C Belt Drive

Robust Construction & Secure Installation

Defined inlet and discharge interfaces simplify connection with industrial ventilation and duct systems.

The fan housing is fabricated from thickened carbon steel and finished with an industrial electrostatic powder coating to prevent corrosion. Pre-drilled flanged air inlets and rectangular discharge outlets allow for quick and airtight coupling to existing factory ductwork. The reinforced, single-piece welded base simplifies floor mounting and guarantees operational stability.

Thickened Carbon Steel — provides structural rigidity for heavy-duty exhausting
Flanged Interfaces — standard circular inlet and rectangular outlet for easy connection
Stable Floor-Mount Base — ensures secure, vibration-free installation

Robust Construction and Secure Installation Interfaces

Wide Range of Applications

Built to handle demanding exhaust and material conveying scenarios across industrial sectors.

Woodworking

Reliable extraction of sawdust, wood chips, and sanding dust from carpentry machinery.

Textile Equipment

Conveying fine airborne fibers, lint, and textile fluff without clogging the impeller.

Factory Workshops

General extraction of heavy industrial dust, smoke, and stale air from production floors.

Material Processing

Strong static pressure for pneumatic conveying of non-corrosive granular materials.

Automated Production Lines

Localized spot cooling and rapid fume exhaust for automated manufacturing cells.

General Ventilation

High-volume air exchange for warehouses, logistics hubs, and large facility HVAC.

LONGWELL — Trusted Industrial Fan Manufacturer Since 1990

Founded in 1990 in Yuyao, Ningbo — the heart of China’s advanced manufacturing belt — LONGWELL has grown from a precision fan component workshop into a vertically integrated ventilation technology group. Today we engineer AC, DC and EC fan and motor systems with 4,000 m²+ of manufacturing floor, dedicated aerodynamics and CFD simulation labs, and a global export network spanning Europe, the Americas and Asia-Pacific.

From material selection to final balancing, every LONGWELL fan is built on automated lines, computer-balanced impellers and 100% run-test before shipment. We are certified to ISO 9001:2015 and ISO 14001, with CE, UL/ETL, RoHS and EAC compliance, and performance tested to the AMCA 210/211 method.

Frequently Asked Questions

Quick technical answers about the LWFDF6-48 dust exhausting centrifugal fan series.

What is the primary application of the LWFDF6-48 centrifugal fan?

The LWFDF6-48 is engineered specifically for extracting and conveying dust-laden air. It is widely used in woodworking shops, textile plants, and material processing lines where the air stream contains wood scraps, fine fibers, and non-corrosive particulate matter.

How does the LWFDF6-48 handle dust and debris?

The fan features a specialized wear-resistant impeller design that minimizes material adhesion and buildup. The internal aerodynamic structure ensures efficient continuous conveying of heavy particulates without clogging.

What are the available drive configurations?

The series is available in Type A (Direct Drive) for a compact footprint, and Type C (Belt Drive) for flexible installation and adjustable transmission ratios, which is ideal for fine-tuning industrial ventilation.

What is the airflow and pressure capacity of the LWFDF6-48 series?

Across the full model range, air volume spans from 684 m³/h to 79,111 m³/h, with total static pressure ranging from 291 Pa up to 3,442 Pa, covering both localized dust collection and plant-wide exhaust systems.

Is the fan casing durable enough for heavy industrial use?

Yes, the scroll casing and mounting base are constructed from thickened carbon steel and finished with high-quality electrostatic powder coating, providing excellent resistance against structural wear, vibration, and corrosion.
