Baru-baru ini, kami telah menyelesaikan sepenuhnya pengeluaran untuk kumpulan penapis hepa dan penapis ulpa yang akan dihantar ke Singapura tidak lama lagi. Each filter must be tested before delivery according to EN1822-1, GB/T13554 and GB2828 standard. The test content mainly include overall size, filter core and frame material, rated air volume, initial resistance, leakage test, efficiency test, etc. Each filter has an exlusive serial number and you can see it on its lable pasted on filter frame.
