STAYNEW MODEL A-3 AUTOMATIC FILTER An endless curtain type oil-bath filter for handling large volumes of heavily dust-laden air at low cost. The efficiency of Staynew Model A-3 is unsurpassed among mechanical self-cleaning filters. Operation and Features: Double filter curtains (1) carried on heavy roller chains driven by sprockets keyed to the shafts of the curtain rollers (2). These rollers float on ball bearings for quiet, frictionless opera tion. Curtains consist of removable anels (3) made of a single layer of ronze screen cloth to which are at tached layers of woven copper mesh. The first of the curtains is the denser, having about twice the im pingement surface of the second or rear curtain. This first curtain acts as the filter and travels through the oil reservoir. The second curtain does not enter the reservoir, but acts only as a safeguard against oil en trainment. This design permits a di rection of curtain travel such that cleaned panels (4) are always on the filtered air side. Therefore no dust can be carried across the back or return side of the front curtain to be blown off and carried on by the flow of air. Patented, exclusive Staynew Air Brush Conditioners (5) prevent excessive amounts of oil being carried upward on the curtain panels and being entrained in the air stream. Specifications Model A-3 Filters are sectional and may be bolted together to obtain any required capacity. Sections come in two widths, 4 ft 3 in. and 2 ft 9 in. Curtain drive and control mechanism (6) arranged either as an integral part of filter unit or for remote mounting, includes a^hp motor (7) driving through a reduction gear and a momen tary contact time switch (8) for testing and checking curtain travel and compressed air control. All are mounted on a common base plate (9) on clean air side of filter. Shear pin (10) is provided for protection of moving parts from accidental damage. The drive motor and the Air Brush Conditioners operate simultaneously for a few seconds at 15 minute intervals* 1144 Dollinger Corporation Air System Equipment * tSd aSLrs Model WKE Panel and Frame Handles and Latches Viscous Model DPV Panel and Frame Model PVR-S Kitchen Range Filter Model BLS {Sectional View) STAYNEW PANEL TYPE FILTERS Model WKE: Dry-type finned panel filter for use in ventilation and air conditioning systems. Extremely large filtering area in relation to overall size. Adaptable to wide variety of filtering media--in fact, almost any medium ob tainable in sheet form that can be crimped. Steel mesh on both sides of medium prevents sagging and makes the WKE fire-resistant (models available to meet Class I Fire Under writers approval), and cleanable without possible damage from vacuum cleaning tool or cleaning nozzle. It may also be washed or dry cleaned when and if necessary. There are no cross bars, spacer bars, or other obstructions to interfere with the cleaning operation. Filter cells are held in rigid box-type supporting frames of heavy gauge metal by spring-loaded cam-type locking latches. Two lifting handles are provided on each cell. Filtering medium supplied already crimped and cut to size. It may be inexpensively replaced in 2 to 5 minutes right at the filter bank--no.special tools required. Frames are drilled so that they can be riveted together to form a flat bank, or by the addition of angle uprights into a "V*' or staggered arrangement. Viscous Panel (Model DPV): A permanent type panel for air conditioning systems used in heavy duty industrial service. Filtering media consist of a series of layers of crimped galvanized screen cloth and woven mesh. These media when coated with PD-10 Pingene Filter Oil form an unusually efficient filter. Model DPV filters are cleaned easily with live steam or by washing in a suitable solvent. Spring-loaded locking latches and lifting handles are pro vided as in Model WKE. Both Model WKE and DPV cells are furnished in 2 in. and 4 in. depths in various standard sizes.
