The High Pressure Constant Volume Regulator limits airflow to a set maximum volume (CFM). Its effective pressure range is between 0.6 and 2.4 InWC. The CVR â€œwingâ€ starts to fly and therefore comes online a little earlier. It provides a little bit of resolution at the high end of the spectrum.
High Pressure CVRs are available in 3â€³, 4â€³, 5â€³, 6â€³, 8â€³ and 10â€³ sizes with airflow ranges between 15 and 720 CFM.
