Product Description

MLWF1800Z Moland Duct-Free Welding Fume Dust Collection Tower 

The Moland Dust Collection Tower is a duct-free, self-recirculating industrial air filtration system purpose-built for welding fume and fine metal dust purification. Designed to solve the most common pain points of traditional centralized dust extraction and portable fume extractors, this all-in-one purification tower eliminates the need for complex ductwork installation, offering a fast, flexible, and cost-effective air cleaning solution for modern fabrication workshops, heavy welding facilities, and aging factory renovations.

Unlike fixed centralized dust collection systems that require extensive pipe layout and costly construction, or portable extractors with limited working radius, our duct-free dust tower delivers full-area workshop air purification with plug-and-play operation. It efficiently captures, filters, and circulates indoor air continuously, maintaining stable workshop air quality while cutting installation and long-term operational costs.

Core Design & Working Principle

Adopting a professional top-air-suction and bottom-air-discharge self-recirculation structure, the Moland dust tower forms a complete internal air circulation system without connecting to external ventilation pipes. Harmful welding fumes and floating fine dust are sucked into the equipment from the top inlet, purified through multi-stage filtration, and clean air is discharged evenly from the bottom to refresh the entire workshop air environment.

With an ultra-compact footprint of less than 3 square meters, the tower saves valuable factory floor space. A single unit covers a purification area of up to 350 square meters, making it ideal for large-space industrial workshops that cannot accommodate scattered dust collection equipment or complicated duct layouts.

Key Technical Features & Advantages

Duct-Free Plug-and-Play Installation

No ductwork installation, construction or factory layout modifications are needed. Simply connect power and compressed air for immediate operation, enabling rapid deployment and flexible repositioning to match production adjustments.

High-Efficiency Fine Filtration Performance

Equipped with 9 flame-retardant PTFE coated filter cartridges, the system achieves 99.9% filtration efficiency for 0.3μm ultra-fine particles. It effectively removes welding smoke and respirable metal dust, fully complying with industrial air quality and occupational safety standards.

Fully Automatic Pulse Jet Cleaning System

The built-in fully automatic pulse jet cleaning system delivers thorough, consistent filter de-dusting. It prevents filter clogging and pressure drops, maintaining stable long-term performance. This low-maintenance design cuts manual work and daily operational costs significantly.

Intelligent Energy-Saving Operation

The intelligent system automatically adjusts fan speed based on real-time workshop fume concentration. It optimizes power output according to actual pollution levels, eliminating unnecessary energy consumption and achieving efficient, eco-friendly, low-cost operation.

Application Scenarios

Solving the common industry pain points of limited portable extractor coverage and troublesome duct installation for central dust removal, our tower adapts perfectly to complex industrial scenarios, including:

• Large-scale workpiece welding workshops

• Factories with overhead cranes and hoisting operations

• Old factory renovation and environmental upgrade projects

• Large-space fabrication, welding, and metal processing workshops

• Production sites requiring flexible station adjustment and no fixed duct layout

Why Choose Moland Self-Recirculating Dust Collection Tower

Traditional welding fume solutions have obvious flaws: fixed ducted systems are costly and inflexible, while portable extractors fail to cover large workpieces and crane-operated workshops. The Moland Dust Collection Tower combines duct-free installation, high-efficiency filtration, intelligent control and wide-area coverage, offering manufacturers a low-investment, high-efficiency, low-maintenance air purification solution. It improves workshop environments, enhances occupational safety, and supports stable environmental compliance.

Product Parameter

Product Details

	Intelligent Control System Our dust collectors adopt Moland self-developed intelligent control system, with a screen showing all function controls and real-time equipment feedback. Key parameters come with lock protection to avoid accidental misoperation and ensure steady operation. The premium Siemens control system is optional, offering stable high-standard automatic management for large welding fume centralized dust removal projects.
	Fully Automatic Pulse Jet Cleaning System Our dust collector features fully automatic pulse jet cleaning with ultra-short 0.1–0.3 second single cleaning cycles. Burst compressed air surges into filter cartridges for rapid expansion and impact vibration, shaking accumulated dust down to the dust hopper. Multi-angle air jet design delivers comprehensive cartridge purging for thorough, low-maintenance filter cleaning.
	0.3-Micron Ultra-Fine Filtration This dust collector adopts imported Japanese Toray flame-retardant PTFE coated polyester filter cartridges, delivering 0.3μm precision filtration with over 99.9% dust removal efficiency to meet industrial exhaust emission standards. Vertically installed filter cartridges boost pulse cleaning performance when capturing coarse particles. The filter replace is very easy to reduce maintenance costs.
	Top Suction and Bottom Discharge Self-circulation  Featuring a reliable top-suction and bottom-discharge self-recirculation design, the tower operates without external ducting. It draws in welding fumes and floating fine dust from the top inlet, purifies the air via cartridge filters filtration, and releases clean air at the bottom to refresh the entire workshop.
	Energy Saving & Low Consumption with VFD Built-in frequency converter allows customized operating frequency settings based on actual workshop conditions. It intelligently matches fan output to real-time fume loads, drastically cutting power consumption while maintaining stable purification efficiency for reliable energy-saving operation.
	All-in-One Intelligent Dust Removal System Our centralized dust extraction system integrates automatic pulse cleaning, energy-saving frequency control, workshop fume concentration monitoring, fire safety protection and human-machine interaction modules (some functions optional). It delivers high-efficiency purification and compliant emissions while cutting energy use and offering user-friendly smart control, supporting full intelligent management for industrial workshops.
