3A 顶篷过滤棉
3A Ceiling Filter
?    风速与阻力的关系：
产品特性：
备有进口PE 网、阻燃网3A-600G/560G 可选；
该系列顶篷棉主要应用汽车涂装、高科电子、军工航天等领先行业；
滤料出风面由进口PE网或阻燃网加固，高阻燃性、高容尘量、初阻力低、安全可靠；
由高性能、抗断裂的进口合成纤维，利用多层逐级加密技术制成；
粘性处理，因粘剂完全渗透介质而使尘埃粒子无法通过，得到全面过滤的空气均匀扩散，形成层流状态，达到很好 的喷涂效果；
符合防火分类标准欧洲DIN53438-Fl 和美国UL9OO-Class2 ;
耐湿性强，可达100 ％相对耐湿度。
Speciality :
3A-600G/560G are backed with imported PE or common non-flammable net scrim .
The series of ceiling filters are mainly used in advanced industries such as car painting , Hi-tech electronics , aerospace and other military areas .
The outlet side of the filter media is reinforced by imported PE net or common non-flammable net. High flame resistance , high dust holding capacity ,low initial resistance, safe and reliable .
Composited of imported high-performance, anti-broken synthetic fiber in gradual technology ;
Due to complete penetration of viscosity in media , dust particles can not pass. Fully filtered air evenly spreads to form a laminar flow state to achieve the best spray results.
Conforming to European DIN53438-Fl and American UL900-Class2;
Moisture resistance, up to 100% relative humidity.
