upon the particular application. There is practically no maintenance required as the larger models are cleaned by turning a valve on the exterior of the ductwork. The water wash manifold is so engineered that all collecting cells are effectively cleaned. Hot water at 125 degreesF., is recommended for washing.

The cost of operation of the smaller units is about three cents a day, with comparable costs for more elaborate installations. It is claimed that with an electronic air cleaner, walls, ceilings, and draperies will remain fresh for long periods of time. The savings in cleaning and maintenance bills is said to make the system pay for itself in a fairly short period of time.

Another important advantage, in addition to the savings in maintenance and cleaning costs, is the healthful benefits of clean air. The elimination of pollen from the air provides complete relief to sufferers of rose fever, hay fever and the like. Sterile air with

bacteria removed, reduces the chance of spread of colds and other respiratory diseases. This is particularly important in theatres where large groups of people sit in close proximity to each other. Better lighting of lounges, lobbies, rest rooms, etc., is another advantage of providing clean air. The dirt and grime which are attracted to lights and lighting fixtures can be greatly reduced by clean air. Often times, the efficiency of a dirty light or fixture will be reduced by as much as 40 per cent.

Air Pollution Problem

Some idea of the amount of dust, smoke, soot, and dirt in the air may be gained by investigations which show that the resident of an average industrial city takes into his lungs each day, at least a teaspoonful of dirt. There is a great cloud of dirt continuously suspended in the atmosphere of industrial areas. In an article concerning the air contamination of an average industrial city, "Fortune Magazineii states: nIf gathered in a single pile, it would create a slopping mountain 1500 feet high, or split equally over the average city, it would bury the city 21 feet deep."


One theatre which has installed

electronic air cleaners with satisfactory results, is the 1500 seat Gateway, Fort Lauderdale, Florida, (see 1952 Theatre Catalog, page 80). One of the finest houses in the Wometco Theatre Circuit, the Gateway is completely modern and up-to-date in its operation. Included, among some of the features are a soundproof cry room complete with cribs and play pens for the youngsters, and a television lounge with rocking chair seats, where free coffee is served at all times. One of the most popular "extras" is the completely clean air.

Patrons who suffer from airborne allergies such as hay fever and asthma receive relief from their wheezes and sneezes. This is accomplished due to the fact that the airborne pollens which cause most allergies range in size from 1/500 to 1/1200 of an inch. The air cleaners at the theatre effectively remove particles from the air as small as 1/250,000 of an inch.

Permission to smoke while relaxing and being entertained is another of the many inducements made possible. A smoking lounge was provided, and it became so popular that an additional charge is now made for the added benefit. The cigarette smoke causes no discomfort for non-smokers or others in the theatre. The smoke particles are carried away through ventilators and ducts to the electronic cleaners where they are collected.

Clean air has been responsible for the theatres extremely low maintenance costs. Pastel walls have remained like new since the theatre was constructed, and should remain so for years according to the resident manager. Seats, draperies, and other furnishings have not been soiled by airborne dirt. Because there is less cleaning of all furnishings, depreciation has been greatly reduced, and less cleaning personnel is necessary. In addition, expensive projection equipment is protected from dirt and dust which decreases efficiency and requires more frequent inspection and cleaning.

The Trion principle for providing clean air is one of the most edicient that has been devised. Air from the outside atmosphere is combined with recirculated air from within the theatre. Upon entering, the air carrying all the harmful and annoying particles, passes through an electrostatic field, and each particle receives a positive electrical charge from fine tungsten wires carrying 13,000 volts direct current. The positively charged particles are then attracted and adhere to negative collector plates. At periodic intervals, from one to four times a month, the built-in water spray system washes all collected matter from the plates. The clean air then passes through cooling coils, and is expelled through diffusers to all parts of the theatre.

The filters require very little space and the cost of operation at the Gateway is approximately five cents a day. According to the manufacturer, the equipment at this theatre will pay for itself, based on savings in cleaning and redecoratng costs, increased patronage, and protection of equipment, within four years or less.
