Why Does Indoor Air Get Worse During a Severe Pollution Crisis?
When outdoor smog peaks, buildings seal their windows. That cuts some outdoor dust, but it also traps CO₂, moisture, cooking fumes, and odours. Without a steady supply of fresh air, indoor air quality drops fast, especially in busy rooms.
A home air purifier only filters air that is already in the room. It cannot replace stale air or reduce CO₂. Ventilation alone brings in fresh air, but it needs filtration so you aren’t pulling coarse dust inside.
Combining both is the ultimate solution. A ducted fan like the AFV-19DP moves fresh air and filters out coarse dust, while a HEPA filter stage or a room air purifier handles the fine particles. Together they form a complete clean-air setup.
What Is the Astberg AFV-19DP?
The AFV-19DP is a compact box-type fan that connects to a duct system. It fits in ceiling voids, plant spaces, and service areas. Its forward-leaning centrifugal fan and sheet metal housing are designed to keep noise low, even at higher airflow.
Built for Quiet, High-Volume Ventilation
- 770 m³/h airflow serves larger rooms, open offices, and clinic areas
- G4 primary filter captures coarse dust before it enters the duct
- 31 dB noise rating suits quiet commercial and residential spaces
- Sheet metal duct structure helps reduce noise
- Forward-leaning centrifugal fan for efficient, low-noise airflow
How Do HVAC, Duct, AHU, and Exhaust Fan Work Together With a HEPA Filter?
Healthy indoor air needs a complete air set: supply, filtration, distribution, and extraction. Each part has its own job.
The Role of Each Component
- Cabinet fan: The AFV-19DP draws air through the G4 filter and moves it through the duct.
- Duct network: The pathway that carries air. At 140 Pa of static pressure, the AFV-19DP suits medium duct runs with a few bends and grilles.
- HVAC: The system that heats, cools, and circulates air. Most HVAC systems recirculate indoor air, so a dedicated fresh air fan adds the outdoor air they lack.
- AHU (Air Handling Unit): In large buildings, an AHU conditions and distributes air centrally. The AFV-19DP provides a compact alternative for rooms and small zones.
- HEPA filter: The G4 filter is a coarse dust filter. For fine particle capture, add a HEPA filter stage downstream or use a room air purifier.
- Exhaust fan or ventilator: If the AFV-19DP supplies air, stale air needs a way out. An exhaust fan or ventilator in the kitchen or bathroom lets the exhaust air leave while fresh air comes in.
The Airflow Path in Four Steps
- Outdoor air enters through the intake.
- The G4 filter removes coarse dust.
- The AFV-19DP delivers up to 770 m³/h through the duct.
- An exhaust fan or ventilator removes stale air, moisture, and odours.

Frequently Asked Questions
How does an AHU differ from a standard home air purifier?
An AHU is a central unit that conditions and distributes air through ductwork across a whole building. A standard home air purifier only filters recirculated air in one room. A compact duct fan like the AFV-19DP sits between the two: it moves filtered fresh air through ductwork without needing a full AHU.
Does the AFV-19DP include a HEPA filter?
No. It includes a G4 primary filter, which captures coarse dust. For fine particles, pair it with a HEPA stage in your duct system or run a home air purifier alongside it.
Do I need an exhaust fan if I install a cabinet ventilation fan?
In most cases, yes. If the AFV-19DP supplies fresh air, stale air, moisture, and cooking fumes need a path out. Pairing it with an exhaust fan or ventilator keeps air moving through the space.
