SAF Rigid, medium to high efﬁciency extended surface deep pleated rigid box ﬁlters are manufactured from a new generation range of high lofted synthetic ﬁber ﬁlter media or micro-ﬁne ﬁber glass ﬁlter media.
SAF Rigid model is made up of superior grade synthetic media and micro-ﬁne glass ﬁber ﬁlter media. In both models the ﬁlter media is laminated with and expanded metal mesh of 98% open area which provides adequate strength to the pleated media pack, supports the media and gives rigidity to the pleats. The three stage media arrangement which consist of coarse ﬁbers upstream, micro-ﬁne ﬁbers downstream and scrim backing to prevent migration, offers high dust holding capacity and ﬁltration efﬁciency. The aerodynamic ﬁlter design by radial V-pleats with die cut pleat stabilizers results in a rigid and stable ﬁlter offering consistent performance under various operating environments. The deep pleated media pack is encased in a metal frame and all the four edges of media are properly bonded to the frame to ensure a leak proof operation.
SAF Rigid is designed for use in systems with variable air volumes and offers performance combined with high dust holding capacity and suitable for applications where highest degree of air cleanliness is required.
SAF Rigid is capable of removing contaminants such as bacteria, fungi, fumes, smoke, etc from the air stream. It is an ideal ﬁne ﬁlter for HVAC systems installed in hospitals, food processing, laboratories, pharmaceutical units, computer rooms, optical and electronic facilities airports terminals, public buildings, etc. SAF Rigid is available in all standard sizes, box style construction or with header frames.
