DustRanger™ – Indoor
Industrial Air Purification for Modern Indoor Spaces
Clean Air. Less Downtime. More Productivity.
The DustRanger™ – Indoor System brings proven industrial filtration technology into fixed indoor environments. Originally developed for demanding use in mining, agriculture, and heavy industry, it is now adapted for workshops, laboratories, offices, and medical spaces — providing professional-grade air purification where it’s needed most. With multi-stage filtration — fine dust, H14 HEPA, and activated carbon — DustRanger™ delivers clean, safe, odor-free air that’s quiet, efficient, and scalable. Initially project-based, the system is now entering rollout — designed for custom installations and high-demand environments requiring reliable, high-performance indoor air solutions.Why DustRanger™ – Indoor?
Unlike consumer purifiers, DustRanger™ – Indoor offers industrial reliability and installation flexibility.
Units can be freestanding, or wall- or ceiling-mounted, capturing dust exactly where it circulates.
Multiple compact modules can be placed strategically and network-controlled, creating a decentralized, high-efficiency clean-air system for large or dusty indoor areas.
Applications
- Production and assembly halls
- Workshops, logistics, soldering, and ESD zones
- Printing and packaging areas (toner dust, paper dust, VOCs)
- Offices and open-plan spaces
- Medical, laboratory, and waiting rooms
- Climbing gyms, fitness centers, and sports facilities
- Containerized or mobile workspaces
Key Advantages
- 3-in-1 flexibility: floor, wall, or ceiling installation
- Zone-based purification: multiple small units instead of one large system
- Low-noise, high-performance: 55–60 dB(A)
- Smart control: app, switch, Wi-Fi sensor, or building automation
- Optional fine dust sensor: triggers automatic purification
- Tool-free maintenance: long-life filters for quick service
- Swiss-engineered: designed for continuous 24/7 operation
How It Works
DustRanger™ – Indoor combines multi-stage filtration with intelligent control:
- Pre- and fine dust filter (ePM / ISO 16890)
- HEPA H14 for ultra-fine particles and aerosols
- Activated carbon module for odor and gas removal
The modular design allows units to be placed where pollutants originate — above printers, along work lines, or in air circulation zones — for faster air turnover, lower energy use, and higher efficiency.
Filter Technology
Each DustRanger™ unit uses advanced honeycomb filter elements with up to 10× more surface area than standard pleated filters.
This ensures:
- Higher dust-holding capacity and longer service life
- Lower pressure drop and improved energy efficiency
- Stable performance in high-dust or humidity environments
- Compact dimensions with maximum filtration output
The honeycomb geometry is available across all filter grades — from coarse and fine dust media to H14 HEPA and activated carbon — giving engineers full flexibility to balance efficiency, durability, and airflow in one modular platform.
Technical Specifications
- Filtration: Dust, H14 HEPA, and activated carbon modules (single or combined)
- Airflow: up to 600 m³/h, variable speed
- Mounting: freestanding, wall, or ceiling
- Power supply: 230 V AC plug-and-play or optional 24 V DC
- Noise level: approx. 55–60 dB(A)
- Control: manual, app-based, or sensor-controlled
- Integration: standalone or HVAC-compatible
- Operation: built for 24/7 use
Smart Air Quality Sensor (optional)
The Longday Wi-Fi Fine Dust Sensor continuously monitors air quality at any chosen point — e.g., above printers, production lines, or busy areas.
It transmits data wirelessly to DustRanger™, which automatically adjusts airflow and fan speed when fine dust levels rise — ensuring on-demand purification that’s both precise and energy-efficient.
Typical Configurations
- Printer zones: tabletop unit + overhead sensor
- Workshops: wall-mounted units along production lines
- Open-plan offices: mix of freestanding and ceiling units
- Waiting rooms: ceiling module with carbon filter + nearby sensor
Health & Safety
DustRanger™ – Indoor removes fine dust, toner, ozone, VOCs, and aerosols, protecting respiratory health and creating a noticeably cleaner indoor environment.
The result: healthier teams, fewer absences, and higher workplace comfort.
Why Zone-Based Air Purification Works Better
- Captures pollutants directly at the source
- Scalable — expand with your workspace
- Energy-efficient — cleans only where needed
- Reliable — if one unit stops, others continue
