Here are a few great fire extinguisher options for you: The Inta Safety 9 Kg DCP Fire Extinguisher is available from R718. As the largest size in the search results, this would provide excellent fire protection for commercial or industrial applications where fires may be larger. The Inta Safety 4.5 Kg DCP Fire Extinguisher for R518 and 2.5 Kg version for R345 are also good mid-sized options that offer strong value and capability without breaking the bank. I'd recommend the Inta Safety brand as they led the search results and seemed to offer consistent quality. Let me know if you need any other details!
