The typical design range we see in our applications range from -2” wg to -28” wg, however we have some systems operating at vacuums of -32” wg to -42” wg under normal operating parameters. Please take into account that our pipe comes in 5’ lengths with a rolled lip on each end, thus providing reinforcement every 5’, which presents a sound structural design that should be stronger than any pipe in its class according to SMACNA guidelines and regulations. Sincerely, Tom Ballus President STRUCTURAL INTEGRITY All fit together ducting systems allow for some degree of leakage. “Q-F” ducting is no exception and is not sold as an airtight system. In addition to our standard Nitrile gasket, NORDFAB offers special clamp gasket material for high heat, food applications, etc. However, the “Q-F” system is sold as a quick way of installing and modifying duct-work while at the same time retaining the usability of each component. In short, “Q-F” is meant to be able to be taken apart, re-assembled, stored or moved. Completely eliminating the possibility for leakage jeopardizes the inherent benefits of the duct. While NORDFAB is currently unaware of any method of evaluating dust collection piping alone, the following data is presented using the criteria for all duct, including HVAC. This data is presented only for the purpose of indicating acceptability of the “Q-F” in dust/fume removal in a negative pressure situation and should not be confused with the ducting that uses tape or gaskets as sealant in the positive conveyance of air.

Nordfab duct is a clamp-together design using a rolled edge design with a single lever clamp. The ducting and clamps are made of similar materials. During manufacturing the duct material sheet blanks, which are five feet long, are rolled and fused together with a laser weld process along the longitudinal seam. Each pipe is checked with a light apparatus for any welding flaws or gaps. The rolled edge is then die-formed after inspection by rolling each end of the pipe simultaneously. The laser weld prevents any gaps in the rolled edge from forming. This rolled end is used for clamping components together as well as offering reinforcement every five feet. All clamps contain a standard gasket made of Nitrile which is suitable for most applications, including oil mist, as long as high temperatures are not an issue. An ePTFE gasket option is available for food grade and high temp applications. Nordfab Quick-Fit Ducting is available in 1” increments sized 3” to 24” diameter. Engineering Specification: 1. Ducting shall consist of the following: a. Galvanized: ASTM A527 with a G90 rating i. Temp rating is 500° F with no breakdown of zinc - Zinc melting point is 740° F b. 304SS: Finish meets ASTM A240 i. Temp rating is 1,100° F c. 316SS: Finish meets ASTM A240 i. Temp rating is 1,100° F 2. Ducting manufacturing techniques: a. Diameters 3” - 24” pipe, adjustable nipples, and collars attached to other components will have one or both ends die formed-rolled to provide a uniform edge around the circumference of the rolled end. The pipe and adjustable nipples shall have the longitudinal seam laser welded to allow for a tighter slip joint and reduce system pressure losses. All laser welded seams will undergo a light test to ensure there are no voids or imperfections in the system. Pipe lengths using laser welded seams will not exceed a nominal 60” length. The rolled edges provide structural support at 5’ intervals or less and can be interpreted as a stiffener where SMACNA specifications are required. An adjustable nipple is used for adjustment during the install process. Pipe is cut to appropriate length and the adjustable nipple secures the pipe for install. b. Pipe and other components larger than 24” shall utilize either an angle flange or flat flange attached loosely and retained in place using a 3/8” vanstone lip. The pipe shall have a compressed-interlocking lap form seam and not exceed 78” in length. The angle or flat flanges provide structural support at 6’-6” intervals or less and are considered as stiffeners where SMACNA specifications are required. c. There will be times when certain components will be air direction sensitive. These components will have an arrow sticker attached showing the proper flow direction. d. All ducting and its components shall have been tested to 80” WG using the following gauged reference: i. 3” will use 18ga material thickness ii. 4” through 12” will use 22ga material thickness iii. 13” through 29” will use 20ga material thickness iv. 30” and above will use 18ga material thickness Engineering Specification (cont.): ZZZGXFWLQJV\VWHPVFRP 4 ENGINEERING SPECIFICATION Return to Contents Ducting Quick-Fit THE WORLD’S FASTEST DUCTING 3. Clamping rolled edged duct: a. Clamps shall be constructed with an over-center, spring-lever action for quick connecting of two pieces of ducting. A retaining pin shall be inserted in the handle and an eyelet on the clamp as a safety feature to ensure the handle does not prematurely come undone. b.

Temperature rating shall not exceed 600°F. 5. Conductivity: a. Metal-to-metal contact shall be obtained at all joint connections. Die-formed rolled edges are uniform in shape which provides the most consistent contact. The ears of the clamp contact with the rolled edges and provide maximum conductivity. Conductivity shall be adhered to per NFPA 77 paragraph 8.4.1.1; states all parts of the continuous metal piping system should have a resistance level that does not exceed 10 ohms. Testing is the responsibility of the owner. ZZZGXFWLQJV\VWHPVFRP 5 COLLAPSIBILITY & LEAKAGE DATA Return to Contents Ducting Quick-Fit THE WORLD’S FASTEST DUCTING COLLAPSIBILITY & LEAKAGE DATA COLLAPSIBILITY STRENGTH OF “Q-F” PIPING Each size of piping has been tested for strength against collapsing. The piping was exposed to constant positive pressure and constant vacuum. Each pipe was exposed to a maximum capacity of the test equipment of 80” WG of vacuum and positive pressure. None of the pipe showed any form of deformation during the test. Please take into account that our pipe comes in 5’ lengths with a rolled lip on each end, thus providing reinforcement every 5’, which presents a sound structural design that should be stronger than any pipe in its class. Pipe and fittings must be installed in accordance with NORDFAB’s standard specifications and standard accepted practices. LEAKAGE RATE All fit together ducting systems allow for some degree of leakage where they are joined. “Q-F” ducting is no exception and is not sold as an airtight system. However, versus the other ducting typically used in fit together systems, Nordfab’s Quick-Fit (Q-F) ducting has fully welded, leak-tight laser welded seams. Spiral and other ducting with lock form seams are NOT fully welded at the seams and can be expected to have higher leakage rates than “Q-F”. In addition to our standard Nitrile gasket, NORDFAB also offers special clamp gasket material for high heat, food applications, etc. Further, the applying of sealants to the individual rolled ends can enhance the tightness of the system. However, the “Q-F” system is sold as a quick way of installing and modifying duct-work while at the same time retaining the usability of each component. In short, “Q-F” is meant to be able to be taken apart, re-assembled, stored, or moved. Completely eliminating the possibility for leakage jeopardizes the inherent benefits of the duct. Standard “Q-F” is designed to provide tight sealing and efficient airflow under negative pressures. To that end, we are providing the following information for piping situations where fan sizing is of extreme importance. The following data was obtained using standard components and was performed in accordance with the SMACNA, “ HVAC AIR DUCT LEAKAGE TEST MANUAL”. The information gives the leakage rate per joint of duct at various pressures. To utilize the chart, count the number of clamps, (this equals the number of pieces), per size and multiply by the number given beside the corresponding diameter and under the applicable pressure. These numbers assume that the product is correctly installed; free of dents in the joining ends and that the gasket is in place. Special gasket material and sealants will increase the sealing capabilities.

See Detail on Right Die Formed Rolled Edge “QF” Clamp Nitrile Gasket Galvanized Style Quick-Seal Clamps Since 1986, the Nordfab Quick-Fit clamp has been the world’s best selling and best sealing duct clamp. It has set the standard for use in industrial dust, mist, smoke and fume collection. Many have tried to imitate it, but we’ve found none who have ever matched, or improved upon, its tight, leak-resistant seal. Until now... The New Nordfab Quick-Seal clamp uses our new revolutionary “overlap” design. This ensures the tightest seal possible. Additionally, we have lengthened the handle for the Quick-Seal clamp and made it stronger, giving you more leverage to clamp down for super tight seals.

Order one clamp per “Q-F” component. • One duct = one clamp • Two elbows = two clamps 2. Specify dimensional information to speed up process: • Transitions A,B,D,L,X, Y and flange style • Branches A x B x C, or A x B x D, or A x B x C x D • Tap-In or In-cuts A, B • Reducer All diameters and end style THERE IS NO SUCH THING AS TOO MUCH INFORMATION ! 3. Look for 60 degree elbows to compliment standard branch orders with 30˚ tap. This is typical application since the two components will create a perpendicular run to the trunk line. 4. Ask for flange styles, hole patterns, ID, OD, when applicable. Typical components requiring flanges will be parts that connect to filters, fans, or other types of equipment. ZZZGXFWLQJV\VWHPVFRP 9 FITTINGS Return to Contents Ducting Quick-Fit THE WORLD’S FASTEST DUCTING FITTINGS A) Branch fittings are produced to have a concentric design, as they taper to a specific dimension. Joints are lapped, spot welded, cleaned, and painted with KRYLON Industrial Tough Coat, Acrylic Enamel #1760 Aluminum. Seams are sealed with 3M Scotch-Seal (R) 2084 grey sealant. B) Fitting gauges vary from 22 to 16 gauge depending on the configuration of the branch or fitting. Gauge can generally be determined by using the corresponding QF Pipe diameter gauge. If exact gauge is required, contact factory for more information. C) All standard branch fittings are produced on a 30 degree angle, however other angles (7.5˚ - 90˚) are available upon request. D) As a normal practice, internal welds are not cleaned or painted. Cleaning or painting the inside is an option based on the customer’s application and is done only at the customer’s request with an upcharge.

Suppose that you have a 5” drop that rises and runs back to join with a 6” drop as sketched above. What size branch will you need? 8” dia (1500 CFM) From Air Volume Chart 5” x 90 Deg Elbow Branch Typ. @ 30 Deg 6” x 60 Deg Elbow 6” Dia @ 885 CFM 5” Dia @ 615 CFM The 5” pipe carries 615 CFM at 4500 FPM, (See Chart). The 6” pipe will need 885 CFM at the same velocity (See Chart). Added together you have a total of (615 + 885) 1500 CFM coming together. Looking again at the chart under 4500 FPM, you find that 1500 CFM is not listed, but falls very close to the 1570 CFM listed for an 8” pipe. This indicates that the 5” joined to the 6” will require an 8” pipe to carry all of the material at the right velocity. The branch, therefore, will be 8” on the downstream end reducing down to a 5” with a 6” branching off of it. That is listed as a 8-6-5 branch.

Through extensive testing by a third party testing facility, Nordfab has developed the Explosion Isolation Flap (EIF) type CARZ to be installed upstream of the dust collector. Without EIF How it works Under normal operation the flap will open as the downstream air moving device generates a flow in the ductwork. Should an explosion happen in the downstream equipment - like a dust collector - a pressure front develops in the ductwork within milliseconds and due to the design of the EIF, the internal flap will be forced closed and seal off the approaching flame front. This prevents glowing embers and burning material from entering into upstream equipment and spaces. The Design The design of the EIF is critical as the flap must function in milliseconds and therefore must be of light construction but must be strong enough to withstand the explosion pressure. With EIF d e s lea Many full scale tests were performed to arrive at the proper design and assure proper function. The Tests e r e ob t n sig Since the EIF is a safety device, Nordfab submitted the EIF to rigorous testing by an accredited testing facility in accordance with 94/9/EC Directive. e d ew Label: ATS.096 CARZ (0120-0500) Label: ATS.098 CARZ (0560-01000) N CE1180 2 Q in ATEX Compliant D St1 The marking is based on product certification by N.B. 1026.

Place the soft grey (or black with grey mark) o-ring seal onto the cut (inside) piece of pipe and seat it evenly against the rolled metal edge of the adjustable nipple. 2 2. Place the harder black o-ring seal against the outside of the inner grey seal. The order should be as follows: a) rolled edge or nipple; against b) soft, small-diameter o-ring; against c) standard Nordfab o-ring Airflow 3 3. Finally clamp the standard Q-F clamp over the rolled metal edge of the adjustable nipple and the hard rolled black o-ring for a leak-free connection. [Make sure both seals fit completely under the clamp and that the air-flows from the cut pipe towards the adjustable nipple]. ZZZGXFWLQJV\VWHPVFRP 44 SIZING A SYSTEM & USING THE CHART Return to Contents Ducting Quick-Fit THE WORLD’S FASTEST DUCTING SIZING A “Q-F” SYSTEM NORDFAB offers assistance to those sales people and customers who have never designed a ducting system before. We can assist you in determining the correct duct size and configuration that will supply you with the correct flow. We have the ability to assist customers in designing a blast-gated system; taking into account flow dynamics that will be affected by blast gates. While blast gates can be used to effectively utilize an undersized filtering system, they can also destroy the flow if not properly placed. USING THE CFM / FPM CHART Different materials need to be moved at different velocities to prevent the material from falling out of the air stream. For example: wood chips and saw dust flow well at 4500 feet per minute. Referring to the chart on the next page, you will see that a 4” duct will convey 395 CFM at 4500 FPM. This will mean that a 4” pick-up on a machine will take 395 CFM from your filtering system; or working in reverse, if you know that a machine will require approximately 400 CFM to remove the waste, then you should design a 4” duct for the purpose.
