Description of the product
Understanding Noise Specs: What Those dB Numbers Really MeanWhen you see noise ratings like 50 dB or 60 dB, what do those numbers actually mean for your business? Let's break it down so you can choose with confidence. All Hercules air doors are tested in a controlled noise chamber with inlet and outlet ducts attached. The listed values have a tolerance range of +3 dB to -7 dB, meaning actual performance may be even quieter than specified. 50–53 dB (FM-125-06, FM-125-18s, FM-125-20s): 57–58 dB (FM-125-09, FM-125-10, FM-125-12): 59–61 dB (FM-125-15, FM-125-18, FM-125-20): The "S" models (FM-125-18s, FM-125-20s) are particularly noteworthy — they move significantly more air (3480–3980 m³/h) while producing only 53 dB of noise. That's exceptional performance for such quiet operation. Don't let noise concerns stop you from getting the protection you need. Hercules gives you powerful airflow in near silence.
