Astberg genuine spare parts for Exhaust & ERV systems:- Condensors
In exhaust fan and ERV (Energy Recovery Ventilator) systems, the "capacity" of a capacitor refers to its capacitance value (measured in microfarads, or MFD) and its voltage rating (measured in VAC).
Typical Capacitor Capacitance (microfarads) Ranges
1. Residential & Small Commercial ERVs / Exhaust Fans
-
Small Exhaust Fans (Bathrooms, Kitchen Hoods): 1.5 microfarads to 4 microfarads
-
Standard Residential ERV Units (microfarads): 2.5microfarads to 7.5 microfarads per fan motor (Note: ERVs usually have two fan motors—one for fresh air supply and one for exhaust air)
2. Commercial ERVs & Heavy-Duty Exhaust Systems
-
Medium Commercial ERVs (microfarads): 7.5 microfarads to 15 microfarads.
-
Large Commercial Exhaust Fans & ERVs (microfarads): 15 microfarads to 30microfarads.

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.
