Heavy-Duty Vehicle Cabin Air Purifier | OEM/ODM Manufacturer

Heavy-duty cabin air purifier engineered for commercial vehicles, buses, and off-highway equipment. Built with a robust aluminum alloy enclosure and multi-stage filtration to capture particulate matter, volatile organic compounds (VOCs), and exhaust fumes in high-pollution operating environments. Designed for direct 12V/24V DC integration into fleet electrical architectures.

Key Features

Multi-Stage Filtration Architecture: Combines a pre-filter for coarse dust, a True HEPA H13 filter (99.97% efficiency at 0.3 microns), and an extruded activated carbon pellet layer for odor and gas adsorption.

Vibration-Resistant Design: Internal components secured with dampening mounts to withstand continuous mechanical vibration in heavy trucks and mining equipment.

PWM Fan Control: Brushless DC motor supports Pulse Width Modulation for precise airflow adjustment and extended service life (exceeding 30,000 operational hours).

Automotive-Grade Materials: Flame-retardant ABS/PC internal housing and powder-coated aluminum exterior meet UL94 V-0 fire safety standards.

Specialty Vehicles: Ambulances, mobile command units, and sanitation trucks requiring containment of biological particulates or noxious odors.

Customization Options (OEM / ODM)

Electrical Interface: Custom wiring harnesses, Deutsch connectors, or integration with vehicle CAN bus protocols (SAE J1939).

Enclosure & Branding: Custom powder-coat RAL color matching, laser-etched logo, and proprietary housing dimensions for tight dashboard or ceiling mounts.

Filter Media Tuning: Optional impregnation with potassium permanganate for specialized chemical scrubbers (exhaust gas mitigation).

Control Logic: Integration with vehicle ignition switch for automated power-on/off sequences.

Manufacturing & Quality Assurance

Production Line: Automated SMT circuit board assembly paired with laser particle counter testing rigs for 100% end-of-line airflow and CADR verification.

Environmental Testing: In-house vibration tables (simulating MIL-STD-810G profiles), temperature chambers (-40°C to +85°C), and salt spray corrosion testing (ASTM B117) for metal components.

Quality Management: Manufactured in an ISO 9001 and IATF 16949 certified facility. Traceability assigned via laser-engraved serial numbers on every unit.

Compliance: CE, FCC, RoHS, and E-Mark certified for automotive electronics deployment.

Frequently Asked Questions

Q: What is the recommended replacement interval for the filter cartridge?

A: Under standard highway operating conditions, replacement is recommended every 6 to 12 months (or approximately 1,500 operating hours). Heavy-duty industrial or mining applications require inspection every 3 months.

Q: Can this unit operate directly on a 24V vehicle electrical system?

A: Yes. The internal power regulation circuit accepts a direct DC input range of 18V to 32V, protecting against alternator voltage spikes and load dumps (ISO 7637-2 compliant).

Q: How is the unit mounted inside the cabin?

A: Mounting is executed via a heavy-duty steel bracket secured to the cabin floor, roof lining, or behind the seat using M6 fasteners. Quick-release latches allow filter changes without tools.

Q: What is the Minimum Order Quantity (MOQ) for custom OEM branding?

A: The standard MOQ for custom housing color and laser-etched branding is 500 units per batch. Prototype samples are available within 15 business days.

Q: Does the unit generate ozone during operation?

A: No. The filtration process relies purely on mechanical and activated carbon adsorption technologies. No ionizers or UV-C ozone-generating lamps are utilized.

Q: What documentation is provided with bulk shipments?

A: Each shipment includes individual test reports (airflow/CADR validation), Material Safety Data Sheets (MSDS) for filter media, CAD STEP files upon request, and certificates of conformity (CoC).
