Astberg Genuine spare parts for Darwin ERV - IFD filters:- AVD35
Standard HEPA filters create high air resistance, forcing your ventilation blowers to work harder and consume more power over time. iFD filtration solves this by delivering high filtration efficiency without suffocating airflow.
-
99.9% PM2.5 Purification: Electrostatically captures micro-particles, dust, pollen, bacteria, and airborne allergens.
-
Zero Replacement Cost: The iFD core is fully washable and reusable. Simply rinse with water to restore 100% filtration performance, saving hundreds in recurring maintenance.
-
Ultra-Low Air Resistance: The open-channel design ensures minimal static pressure drop, reducing fan noise and keeping your ERV running at peak energy efficiency.

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.
