Fine Particle Air Purifier

The FPA-Series Industrial Fine Particle Air Purifier is engineered to capture sub-micron airborne contaminants in manufacturing plants, cleanrooms, and heavy-duty workshops. Built with heavy-gauge cold-rolled steel housing and multi-stage filtration (including optional H14 HEPA and activated carbon modules), this unit achieves a single-pass filtration efficiency of 99.97% for particles down to 0.3 microns.

Operating on direct-drive centrifugal blowers, the system maintains stable static pressure under continuous multi-shift operations. Factory direct manufacturing ensures strict dimensional tolerances, seam-welded airtight enclosures, and reliable performance for facility air quality compliance.

Multi-Stage Filtration Architecture: Combines a washable metal pre-filter (large dust), a synthetic pocket filter (medium particulate), and an H13/H14 HEPA final filter (fine particles).

Airtight Enclosure Design: Laser-cut, CNC-bent, and powder-coated steel casing with closed-cell polyurethane gasketing prevents air bypass and unfiltered leakage.

Direct-Driven EC/AC Motor: Balanced centrifugal impeller engineered for continuous 24/7 operation with low vibration and reduced thermal output.

Differential Pressure Monitoring: Integrated Magnehelic gauges or digital sensors track pressure drop across filters, indicating exact replacement intervals to avoid airflow drop-off.

Modular Configuration: Available as a standalone floor-standing cabinet, mobile rolling unit, or duct-connectable inline module for centralized HVAC tie-in.

Electronics & Semiconductor Cleanrooms: Controls airborne particulate levels to protect sensitive assembly lines from micro-dust contamination.

Laser Cutting & Welding Stations: Captures hazardous metal fumes and fine carbon particulate at the source via flexible extraction arms or direct enclosure ducting.

Pharmaceutical Packaging: Prevents cross-contamination of fine powders and ensures compliance with internal air cleanliness standards.

Precision Machining Workshops: Removes oil mist and fine metallic grinding dust from ambient workshop air, protecting equipment and operators.

Airflow & Footprint: Custom cabinet dimensions and blower sizing tailored to specific ductwork constraints or machinery integration.

Filter Media Selection: Optional chemical gas-phase filtration (impregnated activated carbon / potassium permanganate) for VOC and odor removal alongside particle capture.

Control Interface: Integration with plant PLC systems via Modbus RTU, 0-10V external speed control, or automated pressure-based variable speed drives (VFD).

Electrical Ratings: Configurable voltage options (208V, 415V, 480V) and explosion-proof motor certifications (ATEX / IECEx) for hazardous environments.

Production utilizes automated fiber laser cutting machines, CNC turret punches, and robotic MIG/TIG welding cells to ensure structural uniformity and airtight integrity across all sheet metal assemblies.

Leak Testing: Every assembled housing undergoes negative pressure smoke testing and DOP (Di-octyl phthalate) filter seal testing prior to crating.

Dynamic Balancing: Blower impellers are dynamically balanced to ISO 1940 Grade G2.5 standards to minimize vibration and bearing wear.

Electrical Safety Check: Dielectric withstand testing and ground continuity testing are performed on 100% of finished electrical panels in compliance with CE and UL technical requirements.

Traceability: Raw material mill test certificates (MTC) and motor factory calibration logs are archived for 5 years per unit serial number.
