Skylight Smoke V
NAFFCO DOUBLE FLAP FLAT (DFF) TYPE Smoke vents are designed with single or double flaps with slight slope, which
prevents water accumulation on the flaps. Anodized aluminum alloy frame with multi walls hollow polycarbonate sheet.
It supplies superior air tightness, water tightness, wind load resistance, heat insulation and corrosion resistance.
- Meet the standard GB15930-2007 <Fire dampers for building venting and smoke-venting system>
- Anodized aluminum alloy profile supplies good waterproofing and corrosion resistance.
- Wind load resistance: operational certainty of vents under wind stress equivalent to 1500 Pa
- Water tightness: GB/T7106-2008 Grade 5
- Air tightness: GB/T7106-2008 Grade 5
- K value: lower than 2.7 W/(m2.K)
- Low temperature resistance: -25.
- High temperature resistance: 300 30 mins.
- Reliability: 20000 cycles times opening and closing for daily ventilation, 1000 cycles times opening and closing for smoke exhausting.
- Snow load: operational certainty of vents under snow
load 500Pa.
