Three basic types of air filter are used viscous, dry and continuous. Viscous and dry units are similar in construction, but the filter medium of the viscous type is coated with a viscous material, such as a mineral oil, to retain the dust. The filters are made up from standard, preformed, sections, supported on a frame in a filter housing. The sections are removed periodically for cleaning or replacement. Various designs of continuous filtration equipment are also available, employing either viscous or dry filter elements, but in which the filter is cleaned continuously. A comprehensive description of air-filtration equipment is given by Strauss (1975).

Cartridge filter. Cartridge filters, manufactured from oleophilic materials, are mounted in a filter housing in a vertical position, and are held in place by a special bottom fitting. Cartridges are installed or removed by a simple twist. 

All the components of the local exhaust system should be made from conductive and/or static dissipative materials and electrically grounded. This includes the hoods, ductwork, filter housing, and metal support cages for filter socks (if any). 

Traditional applications of polycarbonate in the medical market, such as filter housings, tubing connectors, and surgical staplers, have relied on the materials unique combination of strength, purity, transparency, and ability to stand all sterili2ation methods (steam, ethylene oxide gas, and gamma radiation). Polycarbonate-based blends blends and copolymers have further extended the materials usefulness to medical applications. 

Filter bags for liquids are effective in removing particulate contaminants in the processing of a wide variety of materials. Bag filtration is a pressure-driven operation, wherein the product to be filtered is forced through the filter unit. Such a unit would normally consist of the filter housing, a retaining basket and the filter bag. 

It is recommended that the special filter be of binder-free glass fibre web of the highest purity. The filtration effect down to 0.01 pm has to be better than an efficiency of 99.9999%. The filter elanent should only consist of solvent-resisting materials, and should not contain any extractable components. The filter housing should have a void volume that is as small as possible and it should be totally free of clearance volume. 

This situation was further exacerbated by the choice of materials for the inlet system. While the filter housing was constructed of stainless steel, the downstream silencer and plenum used a stainless-steel perforated lining for acoustic attenuation, welded to a carbon steel base frame. 

Not only are the filter housings now constructed in AISI 316 but also almost all of the items such as vane separators, door locks, hinges, and instrumentation are supplied in this same material. These inlet systems will give a long life, and they look good as well. A typical system is shown in Figs. A-64 and A-65. 

Materials and Reactions. Candle systems vary in mechanical design and shape but contain the same genetic components (Fig. 1). The candle mass contains a cone of material high in iron which initiates reaction of the soHd chlorate composite. Reaction of the cone material is started by a flash powder train fired by a spring-actuated hammer against a primer. An electrically heated wire has also been used. The candle is wrapped in insulation and held in an outer housing that is equipped with a gas exit port and rehef valve. Other elements of the assembly include gas-conditioning filters and chemicals and supports for vibration and shock resistance (4).
