![]() Typical custom parts include, rectangular to round transitions, special dust collector inlets, overhead welding hoods, pedestal grinding hoods, radial arm saw & chop saw hoods, and any other special part.Ĭlick here to request a quote for spiral ductwork and system components. In addition to our own sheet metal shop located in Seattle, Washington, our vendors Nordfab, Kirk and Blum, US Duct and Jacob Tubing can build any custom hood, transition or special part your project team can imagine. XG-4000PCF Series Aluminum curved frame spiral duct grilles. ![]() These grilles are designed specifically for direct mounting to spiral or round duct. We can custom fabricate any hoods or transitions that your system requires. The spiral duct grilles are available with double deflection blades or perforated face in aluminum or galvanized steel construction. Oval Spiral Duct is an ideal solution where tight clearances are required, and where the pressure requirement of the system prevents the use of square duct. If you are building a spiral ductwork system and need competitive prices on straight duct, hangers, branches, fittings, and components we have you covered! Our spiral ductwork can be joined with sheet metal screws, weld-on angle flanges, or accuflanges. Spiral ductwork and fittings are an economical solution and viable for any application that does not require longitudinal seam ductwork or ductwork without sheet metal screws. Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems. A spiral seam gives this duct greater strength and rigidity than standard duct. Need custom sheet metal parts? Look no further – we’ve got you covered. Crush-Resistant Spiral Duct and Fittings. The table is based on the ducts friction loss formula. The table below can be used to compare equivalent diameters for rectangular and round circular ducts. We can provide preferred clamp-together duct components from or commodity type spiral duct and fittings. The equivalent diameter is the diameter of a circular duct or pipe that gives the same pressure loss as an equivalent rectangular duct or pipe. From standard grilles and registers, to its architectural line of Formations linear slot diffusers, along with a newly released series of displacement diffusers, METALAIRE has the air devices to meet every need. Drop the Profile Nibbler down inside the hole to cut the inner wall of perforated (if it’s a solid inner wall, grab the Drill again first to pop a starting hole).Total Air Energy Solutions is your source for all dust collection, exhaust, and ventilation system components. METALAIRE is the flagship brand of Metal Industries Inc., offering a complete line of air distribution and air terminal products. Duct and venting products help direct airflow through a buildings HVAC system and the intake and exhaust vents. Then take a Duct Knife and cut the Insulation.Ĥ. Using C160 Double cut shears (or PN200 Profile Nibbler) cut out template for diffuser.ģ. Trumpf TruTool C160 (cordless) with Chip ClipperĢ. Using a Standard Drill (like our Trumpf DD1010), insert a Step Bit and pop a starting hole into the outer wall. Steps for Cutting Taps into Double Wall Spiral Pipe Trumpf DD1010 and Step Bitġ. We sell a Battery Powered Profile Nibbler that can go up and over the seams of Spiral Duct but also, because the head length is 2” deep and this tool can cut at a right angle. This allows the ability to drop down inside the hole below the outer wall and cut the inner wall. We’re interested in feedback from the contractor on a method described below. Cuts Grille taps (holes) into the Spiral solid outer wall, insulation, and Perforated Inner Wall. Lockformer Machine Historical Serial NumbersĤ.Elastomeric Insulation-Adhesives, Coating & Tape.Vicon Spiral Pipe Plasma Cutting System There are many advantages of spiral pipe when compared to standard rectangular duct.GRD’s Residential - Supply Air Grilles/Registers.GRD’s Residential - Return Air Grilles/Registers.Gas-Nitrogen, Oxygen, Acetylene, Propane.Insulating a single wall system requires lining spiral ducts with a. Chemicals-Lineset Flush, Lubricants, Leak Detector The lightweight sheet metal is easy to cut and customise so is adaptable to most projects.The blades are adjustable and allow up to a 4 way air. ![]() Chemical-Resistant Duct and Fittings Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes. Radius Spiral Pipe Grilles have a one piece curved frame with gasket to fit flush to the spiral pipe.
