Nordfab’s Quick-Fit (QF) is âThe Worldâs Fastest Ductingâ in every aspect of your dust collection installation. From the time you first need design or quotation assistance, through delivery and installation, to after sales service and replacement parts, Nordfab lives up to being âThe Worldâs Fastest Ductingâ.
- QF clamps together in seconds without welds, bolts, screws, flanges, special tools, precise measurements or specialized skills. It cuts installation time â and duct-related downtime â by more than 40% over traditional ductwork.
- Orders typically ship within 2 to 5 days.
- Once your QF ducting is installed, you can quickly and easily take it apart for cleaning or to reconfigure for any floor plan changes.
Quick-Fit is ideal for most dust, mist and fume collection applications.
Step 1: Preparing to Install Your Ducting. It is important for the installer to understand the layout that the system designer planned for the ducting. Follow all local codes and regulations and note loading capabilities of structures to ensure the ducting is properly supported and that the building can carry the ducting system. If your installer doesnât understand the layout, he will not have all the parts necessary to complete the job. If you do not have a clear understanding or drawing of the system you are about to install, please call the person who designed the system before you begin work.
Step 2: Laying out the duct. Begin by laying the system out on the floor below where it will hang. Remember that two parts that connect will often not be in the same box, so this step dramatically reduces the time it takes to complete the job once the installation begins. This is the step where you could possibly find you are missing a piece, there are obstacles, or the design is not correct; so contact us immediately so we can get a head start on getting you the needed parts.
Step 3: The Adjustable Nipple. One of the most important benefits of Quick-Fit is that it is not necessary to take exact measurements before cutting each piece of pipe. The adjustable nipple is an 11-inch section of pipe that has a slightly larger diameter than a standard Q-F duct.
Step 4: Supporting Your Ductwork. Nordfab has a variety of duct hanging devices, but it is your responsibility to ensure the safety of all ducting. Please check with local agencies to ensure that your ducting is supported in a way that meets local codes. When determining the weight that your ceiling and hangers must supÂ¬port, always allow for the ducting being 100% clogged with whatever material is being conveyed.
Step 5: Pre-Stretch The Clamps. The Nordfab clamps are designed to provide a tight seal, which means that they also require some pressure to close. By pre-stretching the clamp around the rolled edge of a single piece of pipe, you can make it much easier to close when you connect two pieces together.
Step 6: Clamp As Many Parts Together As Possible on the Ground. It is much faster and easier to close the clamps on stable ground than on a scissor lift. Therefore, many installers connect two or three pieces of ductwork together on the floor before lifting them into place.
Step 7: Use the Cotter Pins. After closing each clamp, install one of the enclosed cotter pins into the hole as shown. This ensures that the clamp cannot come open unexpectedly. Install the cotter pin as soon as a clamp is closed and beware of clamps until the cotter pin is safely installed.
