Suction Cleaning Of Equipment

Vacuum cleaning should be used for cleaning all the equipment back stage including footlights, drops, etc. The suction method of dust removal has also been found most effective in maintaining the light reHection and sound transmission qualities of the moving picture sound screen. Frequent applications of the vacuum cleaner will conserve the projection efficiency of the screen with a resulting saving in carbon and current consumption. It will also substantially extend its usefulness.

In the horn and equipment lofts where dust accumulation may affect delicate adjustments, vacuum cleaning can be used to remove the dust and protect an investment of thousands of dollars.

For ventilating ducts, grilles, filters, and generally Wherever dust collects and is difficult to remove by any other method, the vacuum cleaner is indispensable.

In the projection booth where machines require frequent cleaning, vacuum cleaning can again be used to great advantage.

Dust is present in every part of the theatre, and it is always less costly to remove it efficiently than with inefficient brushes, brooms, dust cloths, etc.

Value Of Efficient Tools

The term vacuum cleaner, is broadly applied to all types of machines which remove dust by the force of an induced air current passing over the surface being cleaned. It will be found that their efficiency is usually in almost direct

ratio to their selling price. As in most other pieces of equipment, the theatre is a big plant with big maintenance problems so that the greatest satisfaction and performance will result from the best.

The manager contemplating the purchase of vacuum cleaner equipment should carefully consider this fact: The total cost of: interest on investment, depreciation charges, electrical current, replacement of parts, and upkeep on the most expensive type of cleaning system will never be over 10% of the labor cost necessary to use it. If its efficiency is low, the 90% labor cost goes up or the cleaning suffers. If its efficiency is high, less labor will actually accomplish better results. The first cost of the cleaner must be considered; but its cleaning efficiency is of far greater importance.

Types Available

Vacuum cleaners come in two types: the so-called portable machine; and the installed system, with the machine in the basement and a system of piping extending throughout the building.

Naturally, portable machines cost less than the installed system, and there are several types on the market that clean with a fine degree of efficiency. When first cost must be kept to a minimum their use may be considered; but, even then, only the best should be purchased.

The central system, installed in a new building or Wherever possible in an existing building, will, of course, give the maximum efficiency at the tool end. Also,

it will clean quicker, more thoroughly and with less maintenance cost.

The central system has an added advantage for theatre use. You cannot mix air and dirt without the air becoming foul. With any portable bag type cleaner this air must necessarily be discharged on the spot directly back into the theatre. As contrasted to this, with a central system the air is discharged into a flue and therefore outside of the building itself. This is particularly important today when smoking in many parts of the theatre, added to the almost continuous occupancy of many main stem and grind houses, creates its own pollution problem without the addition of dust.

A clean and fresh smelling theatre brings added enjoyment of the entertainment furnished. A clean and dust free theatre will attract a more desir able clientele.


In conclusion, vacuum cleaning when applied in its fullest efficiency and with equipment having sufficient power to remove dust with a minimum of labor cost will reduce the maintenance cost.
