SOMERS "HAIR GLASS" FILTER (Patented) The Somers Filter Mat requires no adhesive material to catch the dust particles of the air stream in passing between the fibers. Its construction is such that it forms an effective dust bar rier that is highly efficient, the range depending on the type of pack, air stream velocity and the character of the dust. Cleaning the filter is easy and it is a most desirable construction for use where oper ating velocities or temperatures are re latively high or where a high degree of air purity must be secured. "Hair Glass" in this form reacts with practically none of the chemical elements carried in the air stream. It is easy to maintain in proper functioning condition as "Hair Glass" neither rots nor dis integrates in service. "Hair Glass" is pliable and tough, it is both odorless and non-absorptive. Consequently, the user has wide latitude in his methods of hand ling and cleaning the unit. The Somers Filter does not have to be replaced as soon as it fills up with dust. The entire pack may be washed with hot water, cold water, or chemical solvents and as often as necessary, without in the least impairing its operating efficiency. Standard frames and mesh are galvan ized or alloy although other materials can be furnished if required. The Somers filter may be assembled in different thicknesses; > No. 1 Pack--The thinnest, is used where the resistance must be kept low. It is usually employed for domestic applica tions, recirculating systems and gravity flow. No. 2 Pack--Is generally used for all commercial and industrial applications. It will arrest liquid particles in the air stream. Filter units can be made to exact dimensions. Bank holding frames can be supplied.
