QRR0.144G/SMJ Condensed Aerosol Fire Suppression Unit

The QRR0.144G/SMJ Condensed Aerosol Fire Suppression Unit is a high-efficiency and environmentally friendly S-type aerosol fire protection device designed for enclosed spaces.

Upon activation, the unit releases a dense aerosol cloud that interrupts the combustion chain reaction, enabling rapid and effective fire suppression.

With pressure-free storage, high safety, and residue-free discharge, it is ideal for protecting sensitive electrical and electronic equipment without causing damage.
