The Industrial Fine Particle Air Purifier is engineered for continuous particulate extraction in heavy manufacturing environments. Built around a multi-stage filtration architecture incorporating primary pre-filters, high-capacity HEPA/ULPA filters, and optional activated carbon modules, this unit captures airborne particulates down to 0.3 microns with 99.99% efficiency.

Constructed in our 12,000 m² sheet-metal fabrication facility utilizing automated CNC laser cutting and robotic welding, the heavy-gauge steel housing ensures structural rigidity and vibration dampening under continuous plant operation. Integrated in-house sheet metal stamping and automated powder-coating lines guarantee tight seal tolerances, eliminating air bypass and ensuring compliance with industrial workplace air quality standards.

Key Features

Multi-Stage Progressive Filtration: Combines washable aluminum mesh pre-filters, bag filters, and certified H14 HEPA main filters to maximize overall dust-holding capacity and extend core filter service intervals.

Hermetically Sealed Airflow Path: Negative-pressure housing design with precision-machined gasket seals prevents unfiltered air leakage, protecting operators and sensitive cleanroom zones.

Direct-Drive EC Fan Motor: High-static-pressure centrifugal blower delivers stable airflow output while resisting performance degradation as filter loading increases.

Differential Pressure Monitoring: Real-time digital gauge tracks static pressure drop across each filter stage, signaling exact maintenance intervals to prevent airflow drop-off.

Modular Internal Architecture: Tool-free slide-out filter tracks reduce maintenance downtime during scheduled element replacements.

Applications

CNC Machining & Metalworking: Captures fine metal dust, graphite particulates, and oil-mixed aerosols generated during milling, grinding, and turning operations.

Laser Cutting & Welding Stations: Extracts hazardous metal fume particles and fine soot directly at the source before they disperse into the ambient factory air.

Electronics & Semiconductor Assembly: Maintains low particulate counts in auxiliary production zones requiring strict environmental cleanliness.

Battery Manufacturing: Controls fine active material dust (lithium/graphite) during electrode mixing, coating, and slitting stages.

Pharmaceutical Powder Handling: Prevents active pharmaceutical ingredient (API) dust migration during weighing, granulation, and packaging processes.

Customization Options

Enclosure Material Upgrades: Full 304 or 316 stainless steel fabrication for corrosive chemical environments or washdown food-processing zones.

Intake Duct Configurations: Top, side, or multi-port inlet collars (diameters ranging from 150 mm to 350 mm) to match existing plant ductwork.

Gas-Phase Filtration Add-ons: Customizable depth activated carbon or impregnated potassium permanganate media beds for gaseous VOC and odor control.

Control Integration: Modbus RTU / RS485 communication protocols or dry-contact outputs for centralized PLC plant automation monitoring.

Explosion-Proof Configuration: ATEX / IECEx certified motors and non-sparking blower impellers for explosive dust or vapor environments.

Quality Assurance & Manufacturing Control

Sheet Metal Precision: Enclosures are fabricated using Trumpf CNC laser cutting systems maintaining dimensional tolerances within +/- 0.1 mm, ensuring gasket compression uniformity.

Weld Integrity: Structural seams undergo continuous MIG/TIG welding performed by certified welders, followed by dye-penetrant inspection on critical pressure boundaries.

Filter Element Testing: Every HEPA filter element supplied is individually scanned and leak-tested via particle counter downstream per EN 1822 before final assembly insertion.

Electrical & Functional Run Testing: Completed units undergo a 2-hour full-load burn-in test measuring vibration velocity, motor amp draw, and static pressure output on our in-house test bench.

Traceability: Each unit bears a permanent laser-etched serial number linked to raw material mill test certificates and electrical safety inspection records.

Frequently Asked Questions

Q: What is the typical lifespan of the HEPA filter under heavy industrial operation?

A: Under normal two-shift operation in a standard metalworking environment, the main H14 HEPA filter lasts between 6,000 to 8,000 operating hours. Lifespan depends entirely on pre-filter maintenance frequency and ambient dust loading density.

Q: Can this unit handle oil mist combined with fine particulate dust?

A: Yes, provided the system is configured with a multi-stage coalescing pre-filter module prior to the HEPA stage. This traps liquid droplets before they saturate the high-efficiency dry media.

Q: How is filter replacement handled to prevent operator exposure to hazardous dust?

A: Units can be equipped with a bag-in/bag-out (BIBO) containment mechanism or secure slide-out access panels that allow maintenance staff to replace loaded filters without direct contact with captured particulate matter.

Q: What certification documents are provided with shipment?

A: Each shipment includes an individual EN 1822 scan test report for the installed HEPA filter, factory electrical safety test certificates, material compliance sheets, and an operation/maintenance manual.

Q: What is your standard production lead time for bulk orders?

A: Standard catalog configurations ship within 15 to 20 working days. Custom engineering requests involving stainless steel construction or explosion-proof electrical packages require 30 to 45 days.

Q: Do you support OEM/ODM branding for equipment distributors?

A: Yes. We offer private-label sheet metal stamping, custom corporate color powder coating, and customized technical documentation packages for qualified industrial equipment distributors.
