The Mechanical Foam Stored Pressure Type fire extinguisher by Krunal Engineering Works is a highly effective safety solution designed specifically for tackling fires involving flammable liquids and solid combustibles. Built with a durable mild steel body and strictly adhering to IS 15683 standards, this unit ensures reliable performance in critical industrial and commercial environments. It is a versatile choice for locations where both wood/paper risks and fuel/oil hazards are present. This extinguisher works by discharging a specialized aqueous film-forming foam that creates a thick, cooling blanket over the fire. By sealing the surface of the burning material, it rapidly cuts off the oxygen supply and prevents the release of flammable vapors, which effectively stops re-ignition. This "smothering" action makes it the superior choice for Class B fires, such as those involving petrol, diesel, or solvents, while still being powerful enough to soak and extinguish Class A fires like wood and textiles.
Equipped with a constant pressure mechanism and a precision pressure gauge, the unit allows for immediate verification of its operational status at a glance. It is designed to function optimally within a temperature range of +5°C to +55°C, making it suitable for indoor warehouses, mechanical workshops, and fuel stations. The inclusion of a high-quality discharge hose and nozzle ensures that the foam is applied accurately to the base of the fire from a safe distance of 3 meters. These extinguishers from Krunal Engineering Works provide a high fire rating (up to 4A & 55B) while maintaining an impressive 85% discharge efficiency. This ensures that almost the entire volume of foam is utilized to suppress the fire. Whether installed in a garage, a chemical storage area, or a large industrial plant, this foam-based system provides a critical line of defense against complex fire risks.

It works through a "smothering" effect. The foam creates a thick blanket over the liquid surface, which prevents oxygen from reaching the fuel and suppresses the release of flammable vapors.
No. Mechanical Foam extinguishers are water-based and conductive. Using them on live electrical equipment can lead to electric shocks. Always use CO2 or Dry Powder for electrical risks.
Because the extinguishing media is liquid-based, it can freeze or its viscosity can change in sub-zero temperatures. The +5°C to +55°C range ensures the foam remains fluid and effective.
These ratings indicate the size of the fire the unit can extinguish under test conditions. "A" refers to wood/solid trash fires, while "B" refers to square footage or volume of a flammable liquid fire.
