Welcome to Aerocell

Linked to the mining industry Aerocell manufacture spray foam products and lead nitrate for local and international markets. Vent-Seal spray foam is used as an airtight sealant for ventilation control in underground mines particularly in times of crisis.

Underground fires need to be sealed off as soon as possible and usually under severe conditions. By isolating the fire carbon monoxide and other lethal combustion gases are contained and simultaneously the fire is starved of oxygen. Vent-Seal is the ideal product for this application.

During a fire, smoke can cause almost zero visibility, rescue personnel usually wear self-contained breathing apparatus and temperatures can easily exceed 50°C. Dura-Seal ventilation panels are lightweight steel mesh sheets that are erected across the tunnel mouth. Vent-Seal, a self contained, two component spray foam is then sprayed onto the Dura-Seal to produce the seal. Vent-Seal sets within seconds and adheres to dusty rock surfaces. Two people can erect a 3x3m seal in 40 min and the total weight of Vent-Seal and Dura-Seal materials needed is only 88 kg.

Vent-Seal is highly fire retardant and emits very low concentrations of combustion gases when exposed to flame. Vent-Seal has been extensively tested and conforms to the South African National Standard 1867-2003 “expanded foams for use in underground mines” and is accepted for use in Australian mines.

Free training is supplied to customers and the company is on call 24/7/365.

Lead Nitrate is supplied to mines which use it in some processes for the extraction of precious metals from ore.
