Jewel Specialist Powder (Class D) Fire Extinguisher
These Class D Powder Fire Extinguishers are designed exclusively for combustible metal fires. They are intended for use on reactive metals such as lithium, magnesium, sodium, potassium, and aluminium swarf, where standard fire extinguishers are unsafe or ineffective.
All units are supplied with a discharge lance to allow controlled, stand-off application and are suitable for industrial and specialist environments where metal fire risks have been identified.
M28 is a general-purpose Class D powder for a wide range of combustible metal fires, including aluminium swarf, lithium, and mixed metal risks.
L2 is a Class D metal fire powder suited to general engineering and machining environments with reactive metal hazards.
MONNEX is a specialist Class D powder developed for high-energy metal fires, particularly magnesium and magnesium alloy risks.
These extinguishers are for combustible metal fires only (Class D). They are supplied with a discharge lance for safer use, feature heavy-duty construction suitable for industrial applications, and are supplied with a 5-year manufacturer warranty (see datasheet for full terms).
