ASTBERG ABS ASTBERG GRAVITY DAMPER AGD100mm
ASTBERG ABS ASTBERG GRAVITY DAMPER AGD100mm
Protect Your Indoor Air Quality with the ASTBERG ABS Gravity Damper
Scientific design, better sealing, small blowing angle and low wind resistance.
The design of self-drooping without power can effectively prevent air pouring and prevent mosquitoes from entering. Two-way pipe design, the installation is more convenient.
Keep your home or workspace breathing easily and naturally. When the wind howls outside or your exhaust fan powers down, the last thing you want is stale air, lingering odors, or outdoor chills creeping back into your rooms.
The ASTBERG ABS Gravity Damper effortlessly seals off your ventilation system the moment airflow stops. By automatically blocking unwanted drafts before they can enter, it preserves your clean indoor air and keeps your environment comfortable and secure all year round.
Key Features and Technical Specifications:
- Automatic Backdraft Prevention: Self-operating gravity flaps instantly close when the ventilation system shuts off, effectively blocking reverse airflow and outdoor elements.
- Energy-Efficient Operation: Relies entirely on gravity and natural air pressure. It requires zero external power to operate, helping you save on energy costs while maintaining your building's climate control.
- Built to Last: Constructed from high-quality, durable ABS plastic that strongly resists wear, moisture, and environmental factors for long-term reliability.
- Standardized Fit: Engineered specifically with a 100mm diameter for a seamless, hassle-free installation into your existing standard ductwork and ventilation systems.
- Enhanced Air Quality: Effectively seals your ducts against returning odors, dust, and pests, ensuring the air you breathe remains consistently fresh.

Green Impact Estimator
What efficiency gives back.
Slide to match how you would run this unit. We will do the maths on the energy, money and carbon it hands back — every single year.
Your usage
Estimates compare this unit's rated draw against a conventional AC fan of similar airflow, at your local grid emission factor. Actual figures vary with speed setting and duct design.
Acoustics
Powerful. Not loud.
Thousands of cubic metres of air every hour, engineered to stay out of your conversations. Here is where this unit sits on the sound scale.
Sound pressure in dB(A), typical values at 3 m. The scale is logarithmic — every 10 dB drop is roughly half the perceived loudness.
