Tambayoyin Fasaha da Amsoshi

Q1: Menene babban fa’ida na ƙirar FluidLoc (Zaɓi 36) akan kebul na tsawaitawa na al’ada?
A1: Kebul na yau da kullum na iya aiki kamar bututu idan an yanke rufin waje, yana barin mai mai matsin lamba, danshi, ko sinadarai su ratsa cikin zaren da ke ciki. Kebul na FluidLoc suna da toshe-toshe a ciki da ke hana iskar gas da ruwa yin hijira ta cikin kebul, suna kare akwatin haɗa wayoyi da allunan dakin kula daga mai ko ruwan aiki mai haɗari.
