a) Cordierite DPF
Cordierite DPF (Diesel Particulate Filter) is mainly used to filter out the particulate from the diesel engine emissions.
Company now has developed the asymmetric DPF (300/9) for GB VI, Off Road T4.
With above 10 years’ experience of DPF production, our DPF has been well known and recognized by all customers for its good quality and reliable function.
