CHICAGO, ILLINOIS H A I R C R A F T, HAIRBESTOS and NATURZONE Modern specifications are demanding in sulating materials that not only give adequate protection, but also lend them selves to the contours of modern design. For this purpose, Wilson's Haircraft and Hairbestos (flexible blanket type materials) are ideal. Haircraft is made with 100 per cent hair filler between Kraft Duplex Asphalt paper, stitched in rows INSULATION every 2 in., the width of the material. It has a low conductance of 0.26 in a oneinch thickness. Hairbestos is of the same character as Haircraft, with the exception that it is fire-resisting and covered with crinkled asbestos paper. Naturzone insulation is the standard board form of insulating material for use where a rigid form of material is necessary. It is made of sterilized, deodorized hair compressed into board form of standard size, 36 in. x 16 in. x 1 in., 1^4 in., 2 in. and 3 in. thick. It has a conductivity of 0.27 per square foot per hour per inch of thick ness. The ability to knit itself into a single unit in a very short time makes the efficiency of Naturzone a superior form of insulation. F I l T E R A I R E AIR FILTERS maintain an expanded condition, pressing constantly outward against the sides of.the, container, preventing packing and sag ging. A special fixative maintains the form of the entire pad. The outlet side of the pad is treated with a special adhesive oil for catching and retaining the dust. Filter Cell Rating In the Filteraire filter, Wilson & Co. has introduced Keratin fibers (animal hair). They are thoroughly sterilized and deodorized and subjected to successive mechanical and chemical treatments. In the individual cell, the central por tion is built of fibers which are highly resilient. This characteristic helps to Capacity per cell...... ...................800 CFM Face velocity-- ......................300 FPM Resistance, per unit (two filters 0.18 in w.g. tandem arrangements). These ratings are for. standard 20 x 20 x 2 or 16 x 25 x 2 Filteraire filters. Special size filters are supplied on order. The fibers on the face of the filter are formed mechanically into corrugations and are not coated with adhesive. This treat ment allows the dust to enter the cell in stead of packing up on the surface, in suring exceptional dust-holding capacity. 962 Insulation, Underground The Ric-wiL Company Agents In Principal Cities CONDUIT SYSTEMS FOR UNDERGROUND STEAM PIPES Union Trust Bldg. new york-chicago-san francisco Established in 1910 Cleveland, Ohio Conduit--Standard conduit is vitrified salt glazed tile or cast-iron with Loc-liP Side Joints, bell and spigot type, unlined or lined.
