OGNEZA-OVM fire-resistant ventilation mastic (OGNEZA OM-VENT system)
Non-combustible mastic for fire protection of air ducts — an alternative to basalt materials; EI 30, EI 45, EI 60 per GOST R 53299-2019.

Single cables and bundles are passed through walls and floors via the OGNEZA-PM-K penetration. The design is a split red powder-coated steel body with an OGNEZA-TRM insert that expands from +150 °C. The penetration is installed from both sides — in a sleeve, in a metal embedded pipe or in an opening with mineral wool. The fire resistance rating is IET 180, the operating range from −50 to +80 °C, and the service life 30 years. Sizes range from PM-K-20/40 to PM-K-125.
