The Lumeike"Large Self-Circulating Industrial Air Purification Unit" is a revolutionary solution designed specifically to overcome air pollution control challenges in high-bay industrial facilities, such as large-scale welding workshops. It abandons the high costs and limitations of traditional ducted centralized dust collection systems. Instead, it employs an innovative "on-site capture, local purification, and clean air reuse" self-circulating model. Integrating a high-efficiency multi-stage filtration system, intelligent controls, and a high-volume fan, this unit efficiently captures and purifies pollutants like welding fumes and dust without complex ductwork installation. It maintains indoor air cleanliness and temperature stability, offering an economical, flexible, and highly efficient air purification solution for large industrial spaces.
2. Pain Points Addressed
Directly targets critical challenges in large-space pollution control:
3. Product Features & Key Highlights
- Revolutionary Self-Circulating Design:
- No Ductwork Required: Units operate independently, eliminating the need for expensive, complex, and space-consuming duct systems. Significantly reduces CAPEX and installation time.
- Local Purification & Air Reuse: Contaminated air is captured, purified, and the clean air is directly discharged back into the workshop. This creates localized air circulation, effectively maintaining indoor air quality while preventing massive heat loss in winter or cool air loss in summer.
- Outstanding Performance:
- High Capture Efficiency & Extensive Coverage: Optimized intake design and powerful fans generate strong negative pressure and long-range capture capability, effectively covering large polluted areas and solving scattered emission point challenges.
- High-Efficiency Multi-Stage Filtration: Standard high-efficiency filter cartridges (e.g., PTFE membrane-coated nano flame-retardant cartridges) achieve ≥99.9% filtration efficiency for welding fumes (especially sub-micron metal particles) and dust (Higher grades like H14 HEPA available upon request).
- Energy Efficient: Utilizes high-efficiency, low-noise fans and intelligent airflow control, resulting in significantly lower operational energy consumption than traditional systems. Modular design allows units to be switched on/off as needed, preventing energy waste from over-capacity operation ("big horse pulling small cart").
4. Application Scenarios
Core Application: Large and extra-large workpiece welding workshops – Aircraft manufacturing & maintenance, Shipbuilding, Heavy steel structures, Large engineering machinery, Rail vehicle manufacturing, Container manufacturing, Large automotive plants (e.g., body welding lines).
Extended Applications (All scenarios with hard-to-capture-at-source smoke, fume, or dust):
- Metalworking: Laser cutting, Plasma cutting, Grinding & polishing workshops.
- Chemical/Rubber: Rubber compounding & vulcanization areas; Dust & VOC generation during chemical raw material handling (charging, mixing, packaging).
- Food Processing: Dust, oil mist, and odors from raw material handling (crushing, sieving), baking, frying, spraying (e.g., chocolate coating).
- Pharmaceuticals: Dust and potential cross-contamination control in API production (milling, blending, granulation, drying, coating).
- Woodworking: Wood dust, Paint/spray booth exhaust.
- Foundry/Forging: Pouring, shakeout, and cleaning areas generating fumes and dust.
Others: Large warehouses, Logistics centers (forklift exhaust, dust), Large maintenance bays.
5. Working Principle
The unit follows a closed-loop "Capture - Filter - Reuse Clean Air (+ Conditioning)" process:
The self-circulating industrial air filtration machine sends the purified air into the work area and forms a thinner air layer on the ground. The air layer is made from cooler fresh air. The indoor heat source (personnel and equipment) produces upward convective airflow. Fresh air flows to the upper part of the room due to the buoyancy of the heat source and leads to the dominant air flow for indoor air movement. The exhaust vent is placed on the top of the device and sucks polluted air into the interior of the device. The air supply speed of the air purification filter is about <0.5m/s. The momentum of the air supply is so low that it has no practical effect on the dominant airflow in the room.
