5kg Carbon Dioxide Aluminium (89B) Fire Extinguisher

Description

Our 5kg CO2 aluminium fire extinguisher (89B) is a high-capacity carbon dioxide extinguisher designed for larger electrical risk areas and Class B flammable liquid risks where the premises fire risk assessment permits. CO2 fire extinguishers are commonly specified for plant rooms, switch rooms, server rooms, workshops, laboratories, warehouses and larger commercial premises because they leave no residue, helping protect sensitive electrical equipment and reduce clean-up disruption. When customers search for a “5kg CO2 fire extinguisher”, “89B CO2 extinguisher”, or “CO2 extinguisher for electrical rooms”, this aluminium model is a strong choice where we want high performance with a lighter cylinder for easier handling and a premium finish.

This unit is supplied complete with hose and horn, improving reach and control during discharge compared with smaller horn-only CO2 extinguishers. The aluminium cylinder helps reduce overall weight, making it easier to handle during installation and servicing, and it suits customer-facing environments where presentation matters alongside compliance. It is supplied with a wall mounting bracket so we can install it in clearly visible, accessible locations aligned to the fire risk assessment and the building’s fire safety arrangements.

Please note: This extinguisher is supplied uncommissioned. To ensure it has been correctly installed, identified and made ready for service, commissioning by a competent person is required. We can provide commissioning and installation services as part of our fire extinguisher supply package.
