Midwest Air Filter Unit
New Model Type U2
OUTSTANDING FEATURES OF MIDWEST AIR FILTERS
An installation is built up of standard, interchangeable units (consisting of a frame and a filter cell 20 x 20 x 6I/2 overall, with a capacity of 800 C.F.M. per unit). A positive air-seal is provided between each cell and frame, and between adjoining frames on all sides.
The unique Midwest baffle-impingement principle makes these filters the most efficient air cleaners in existence. The filter medium consists of a series of specially shaped and perforated metal sheets coated with a sticky viscous fluid. Dusty air in passing through the filter cell, is forced to change its direction innumerable times.
Dust particles are impinged against the sticky surfaces of the filter sheets, where they are caught and held. A series of specially designed sheets of knitted metal mesh are provided at the rear portion of the cell, on which fine dust particles which might pass the first filter sheets are impinged and caught.
Each cell holds a large amount of dust and does not clog up. A constant operating resistance of
water gauge is maintained by routine cleaning. One man, on a small part of his time, takes care of the average installation.
For Churches, Temples, Etc.
CLEAN air for such buildings as churches, temples, auditoriums, and theatres, is needed not only because the menace of atmospheric dust and bacteria is at its worse where a large number of people regularly congregate, but because the damaging effects of dust on decorations and fixtures is apt to be felt the most in such buildings.
Midwest Air Filters have been installed or are being installed in so large a number of these buildings all over the country that there can be no question either of the general appreciation of their need for clean air or of the ability of our filters to supply it economically and efficiently.
Here are a few of the more prominent buildings on the list: —
