7 Litre Wet Chemical Fire Extinguisher

Description

The 7 litre wet chemical extinguisher is the standard unit for commercial kitchens, restaurants, and deep fryer environments. Wet chemical agent works by reacting with hot cooking oil to form a soapy foam crust (saponification) that seals the fire and prevents reignition — a reaction that dry powder or CO2 cannot replicate. Required for Class F fire compliance in any commercial kitchen with deep fryers or cooking oil equipment. Approved and manufactured to AS/NZS 1841.3.

Compliance & Servicing

Manufactured to AS/NZS 1841.3. In accordance with AS 1851, wet chemical extinguishers must be inspected every 6 months and serviced annually by a licensed fire protection technician.

Frequently Asked Questions

Why do commercial kitchens need a wet chemical extinguisher?
Cooking oil fires (Class F) reach extremely high temperatures and cannot be extinguished by powder or CO2 alone. Wet chemical agent reacts with the burning oil to form a foam seal that cools the surface and prevents reignition. This is the only agent type rated for deep fryer and commercial cooking oil fires in Australia.

Can I use a wet chemical extinguisher on other types of fires?
Yes — this unit is also rated for Class A fires (wood, paper, textiles). However, it is not rated for Class B (flammable liquids), Class C (gas), or Class E (live electrical equipment). For mixed-risk environments, you may need additional extinguisher types.

What size wet chemical do I need for my kitchen?
This depends on the volume of cooking oil in your deepest fryer. The 7 litre unit suits most commercial kitchen setups with fryers up to approximately 75 litres of oil. For larger fryers, or multiple fryers, consult a licensed fire protection technician for a compliance assessment.

How often does it need to be serviced?
Every 6 months for inspection and annually for a full service by a licensed fire protection technician, as required by AS 1851. A maintenance test tag is included.

Does it come with a wall bracket?
Yes — a wall bracket and maintenance test tag are included as standard.
