Breaking Down Dust Collectors and Dust Control Systems for Your Application
The same way that Kice Industries has made a name for itself by creating some of the most innovative pneumatic conveying systems in the industry, we’re also well known for controlling dust. A “Dust Duct” is a total system of pre-engineered, welded metal ducting and fittings for dust collection and control work. Dust ducts can often be found in warehouses or facilities that operate in material handling or other products that have a by-product of dust that needs to be managed.
There are more than 25 different types of fittings in a full range of sizes from 2″ to 36″ diameter – by half-inch increments.
With the exception of unusual or extremely large dust control jobs, these types and sizes cover almost 100% of the requirements for air pollution and dust control systems.

DUST DUCT CONSTRUCTION STANDARDS
The vast majority of Dust Ducts are constructed of 16-gauge mild steel (through 17” OD size) and joined together by CC couplings. Large size fittings (18” OD and larger) are 14-gauge and fittings under 8” OD diameter are typically called out as Kice Speed Spout fittings when applicable. Larger size fittings are connected with flanges. The standard finish for steel Dust Ducts is a finish coat of Kice white paint. Some fittings 8” OD and below that are called out as Speed Spout items may not be painted as standard. Other materials such as aluminum and stainless steel are available upon request.
Dust Duct fittings such as transitions and tapers are made with short straight end collars to permit joining by standard compression couplings or flanges. Collar lengths are 4”, 5″ or 6″ depending on diameter.
Flanged straight pipe and ells are normally supplied with one flange welded to one end, and the other flange loose so it can be welded in the field so bolt holes can be aligned to fit as required. Other fittings may have all flanges welded on. Note that longitudinal seams are normally centered top or bottom. Flanges are welded to the part so one bolt hole is in line with the seam. Fittings are made with collars, even when flanged.
We can tag the dust duct items with any tagging information required, options shown below. If
you want these items tagged please specify at time of quote or order.
Most dust duct items are crated for protection from freight damage during transit. Crating
charges vary depending on size and quantity.
SELF READING PART NUMBER
The part number code is the key to understanding the overall system. It is a convenient form of shorthand that can universally be used by system designers, the purchasing department, billing, warehousing, invoicing, and for catalog purposes. It greatly simplifies the system layout. A single line diagram, with components specified by Dust Duct part numbers, can convey as much information as detailed drawings yet can be drawn in a fraction of the time.
To break this down, a Dust Duct part number consists of a prefix with one or more pairs of dash numbers. The prefix includes two letters and two digits. The two letters indicate the fitting type and the two digits indicate its main dimension “A” (usually diameter) in inches – and halves where applicable. This is followed by one or more pairs of numbers (separated by dashes) indicating other dimensions – B, C or D, corresponding with drawings in the catalog. A single-digit dimension (less than 10″) should be written with a zero ahead of it, thus -07.
Typically, a section of straight pipe 12″ diameter and 120″ long would be part number SS12-120. The letters “SS” indicate Section and Straight. The number “12″ indicates dimension “A” (tubing diameter) is 12 inches. The dash tells us there is no fraction. The “120” following the dash indicates the pipe length “B” (per catalog drawing) to be 120 inches. SS12½-60 would be 12½” diameter and 60” overall length.
More complex parts that require additional dimensions in order to specify essential items have more digits in the part number. These dimensions are indicated in the catalog drawing by letters. The part number dimensions correspond to the letters in alphabetical order.
It is necessary to refer to the catalog drawing to be sure you properly relate each code letter with its dimension. The drawings show certain common dimensions, angles, and ratios. Unless otherwise specified, collars will be the standard dimensions as well as flanges. If non-standard collars and/or flanges are required, full information should be furnished with the order, preferably by sketch. Custom-design fittings are available.
