DM ‘35’ & ‘45’ Self-Sealing Rectangular Flange Connector Systems
The innovative DM ‘35’ and ‘45’ systems are designed for applications where strong, leak-free connections are critical. Ideal for data centers, semiconductor plants, battery plants, wastewater treatment plants, chemical plants, oil rigs, stadiums and arenas, underground transit stations, and more.
Forget about struggling with traditional, labor-intensive methods for connecting heavy-duty ductwork. Backed by rigorous testing and our industry-leading guarantee, this superior solution not only saves you time, money, and effort but also ensures exceptional performance, making your operations more efficient and cost-effective.
The system features precision-engineered components for seamless assembly:
- Roll-formed Flanges with Integral Mastic: Ensure a tight seal against the duct wall for a superior, leak-free connection. Integrated mastic eliminates the need for separate sealant applications, saving time and labor during assembly.
- Corners: Reinforce the ductwork structure to hold everything together securely and provide a dedicated sealing surface for the gasket, further optimizing the system’s airtight integrity.
- Gasket: Forms a vital barrier between the flanges to prevent air leaks and ensures optimal airflow within the duct system.
- Cleats (Versa-Cleat or Bolt-On): Guarantee consistent compression and secure, efficient assembly, even on large duct spans.
With DM ‘35’ equal in strength to a SMACNA J-class and DM ‘45’ equal to a SMACNA K-class transverse joints, these systems provide the strength you need to connect the biggest duct imaginable without the labor-intensive fabrication processes of drilling bolt holes, welding frames, or applying rust-proof coatings. It’s no wonder that the DM ’35’ and ’45’ systems have become the clear choice over the labor-intensive companion angle.
Available in seven alloys (galvanized, galvanneal, aluminum (except cleat), aluminized, 304 stainless, 316 stainless, PVC-coated, and black iron), and with a variety of snap-on or bolt-on cleat, corner options, and more, the DM ‘35’ and ‘45’ systems are the ideal solution for your industrial and mega project problems.
PolyArmor Duct Liner Insulation
Ductmate’s PolyArmor™ polyester insulation is engineered to address the shortcomings of traditional insulation materials, offering a superior alternative with several compelling advantages:
- Fiber-Free and Safe: PolyArmor eliminates fiber shedding and does not break down in the airstream, creating a cleaner and healthier indoor environment. Its polyester material is soft and hypoallergenic, eliminating irritation during handling that you would typically experience with fiberglass insulation.
- Superior Moisture Resistance: PolyArmor’s polyester construction provides exceptional resistance to moisture and condensation, minimizing the risk of mold growth.
- Easy Installation: Designed for ease of installation, PolyArmor reduces labor costs and installation time, with its flexible nature allowing it to conform to any duct shape.
- Enhanced Thermal Performance: PolyArmor provides industry-leading R-values/thermal resistance, contributing to increased energy efficiency and reduced system load.
- Durability and Longevity: PolyArmor is engineered from strong and safe polyester that is webbed into a thermal blanket, which is then bonded with an extremely durable FSK-facing that reduces damage during fabrication, operation, and cleaning.
- Environmental Benefits: Made with environmental sustainability in mind, PolyArmor is manufactured from 25% recycled content.
Access Doors
Sandwich Access Doors
Sandwich® Doors are solid, leak-proof access doors that are simple to install, providing easy access to ductwork. Its unique sandwich-style design with knobs that are easily turned by hand allows for effortless opening and closing with no tools required, and no measuring needed, thanks to a provided self-adhesive template.
Sandwich Doors are available in both insulated and uninsulated options, as well as a wide variety of alloys. Additionally, single-pane and double-pane observation-style sandwich access doors are available to allow for viewing inside duct without door removal.
ULtimate Access Doors
The ULtimate Door™ provides easy access to high-temperature air ducts and grease duct systems, and is designed for applications requiring a UL 1978 listing. Unlike shop-fabricated and inferior, light-gauge grease duct door substitutes, Ductmate’s high-performance ULtimate Doors are designed to meet the challenges. They are the most extensively engineered, tested, and ruggedly constructed doors available in the industry.
ULtimate Doors are grease and liquid-tight with minimal penetration into the duct, and are UL 1978-listed and meet NFPA 96 standards. Its sandwich-style design allows them to be completely removed or installed in minutes. No frames to install, no holes to drill, and no clips needed, dramatically reducing field installation time and labor. The ULtimate Door and ULtimate Door Round, and the weld-on style ULtimate Door II are available for when life safety and building performance are your top priority.
ULtimate Doors are available in custom sizes ranging from 6×6” to 24×24” in stainless steel 304 or black iron and with optional design features for virtually any configuration. Consult Customer Service for more information.
Hangers
Pre-Punched Trapeze Duct Hanger
The Pre-Punched Trapeze Duct Hanger is a specialized duct support channel designed to support rectangular and oval ductwork. Made from 18-gauge galvanized steel and measuring 2″ high x 1.5″ wide, this lightweight and easy-to-cut product arrives at the job site in 20-foot lengths, pre-punched with oval holes at 2-inch intervals for immediate use.
Its versatile design eliminates the need for hard-to-cut and punch-angle iron, and it can be standardized to replace multiple hanger types, thereby potentially reducing inventory costs. The hanger’s neat, professional appearance is complemented by the option to insert heavy neoprene gaskets for sound isolation, and it can be secured to structural members up to 1.5 inches thick using its beam clamp.
Isolation Hanger Type SI
The Isolation Hanger Type SI is a sturdy, vibration-isolating steel hanging bracket featuring a rubber isolation pad, designed for use with threaded rods to suspend ductwork and other equipment, isolating vibration at its source.
Capable of supporting up to 1100 lbs (499 kg), the sturdy tension brackets have a much greater load-bearing capacity than the corresponding threaded rods. Its styrene-butadiene rubber padding isolates vibration at its source, preventing distracting noise transmission and extending the lifespan of HVAC equipment by reducing wear and tear. The outside dimensions match standard wrench sizes, so no special tools are required, making installation easy. The open space of the bracket corresponds to the width of the nut, preventing it from turning.
Round Duct Hanger
Install your round ductwork quickly and effortlessly with our Round Duct Hanger. This prefabricated hanger features a ¼” x 20 carriage bolt with a zinc-plated wing nut and lock washer for secure, tool-free installation. Available in a range of sizes from 3” to 10” in 1” increments and 12” to 34” in 2” increments to perfectly fit your ductwork. Constructed from durable 20-gauge galvanized metal for long-lasting performance.
Round Duct Strap Bracket
Our versatile Round Duct Strap Bracket supports ductwork up to a generous 50” diameter. Designed to accommodate 1” wide strapping in gauges 18-22, it offers flexible installation options. Easily attach your preferred hanging system with compatibility for Cable Shark Hanger Adapters, 3/8” and 5/16” rods, or eyebolts. This bracket is a crucial component for secure and efficient ductwork suspension when used in conjunction with strapping and your chosen hanging method.
Hanger Strap
Our versatile Hanger Strap makes it easy to tackle hanging ductwork. Available in convenient boxes, bundles, or coils and in galvanized and stainless-steel options, this essential component is perfect for even the most challenging installations.
Vinyl Duct Strapping
Quickly and easily secure your flexible or lightweight ductwork with our Vinyl Duct Strapping. This strong, all-purpose fabric is perfect for small-scale installations, and its durable construction ensures reliable support for hanging your ductwork.
