OGRAX-VENT air duct fire protection system (OGRAX-BM + OGRAX-K adhesive)

Fire protection of air ducts

The OGRAX-VENT system is designed for air ducts of general exchange, smoke control and emergency ventilation, air conditioning and local exhaust systems, as well as for flue gas ducts and chimneys. It consists of OGRAX-BM foil-faced basalt material and OGRAX-K fire-resistant adhesive: the adhesive is applied by trowel, brush or spray, and the mat is laid foil side out with an overlap and, if necessary, secured with clamps and aluminium tape. Fire resistance is EI 60 or EI 90. The service life equals that of the air duct; we supply both components.
