OGRAX-VENT air duct fire protection system (OGRAX-BM + OGRAX-K adhesive)
Fire protection of air ducts with OGRAX-BM foil-faced basalt material on OGRAX-K adhesive; EI 60 and EI 90 ratings.
OGRAX-OTP pillows are packed tightly into the opening around the cables. Each one is a fibreglass fabric casing filled with intumescent material and mineral filler. They are used in OGRAX-VKP temporary cable penetrations, OGRAX-PKU permanent penetrations and in fire barrier belts. Fire resistance is up to 120 minutes; the pillows work in enclosed premises with humidity up to 100% and outdoors. There are three standard sizes, others are made to order; the service life is 40 years.
