Variable Duct Systems
Vanaire designs and manufacture corrosion resistant duct systems and Factory Mutual duct systems in accordance with the specifications set forth by the SMACNA Manual on Thermoplastic Construction. We guarantee substantial, leak-proof performance of Vanaire duct applications and effective functioning of the whole ventilation system.
Corrosion-resistant Materials of Construction for Duct Systems
Vanaire has the expertise and capability to manufacture ducting in a wide variety of corrosion resistant, durable materials:
- PVC
- CPVC
- Solid Fiberglass
- Filament Wound Fiberglass
- Polypropylene
- PVDF
- Dual Laminates
PVC Duct – fabricate PVC ductwork systems from 3/16″ Type II extruded PVC (conforming to ASTM-D-1784-69) in diameters 6-inches through 24-inches. And we use Type II PVC sheet stock of 3/16″ and 1/4″ thickness for diameters greater than 24-inches (conforming to ASTM-D-1927-67). Vanaire also assures solid welding of all the joints and elbows to provide the customers with the best solutions for their ducting challenges. Vanaire engineers have been refining the designs and looking for new firm materials to manufacture exceptional duct systems. We offer to our customers exclusive solutions like:
- Solid Fiberglass Round Duct – manufactured from chemical resistant reinforced-thermoset resin in accordance with product standard PS-15-69. The size of round duct is determined by the inside diameter.
- Filament Wound Fiberglass Ductwork – constructed utilizing our state of the art filament winding machines.
Fabrication Sizes For Ducting
Standard sizes for ducting and duct fittings (link to duct fittings page) is 6 inches through 24 inches. However as we are a custom fabricator, we can design and build systems for your specific needs. Call us for a quote on custom sizes.
Specifications for Fabrication of Ductwork and Duct Fittings
All PVC and Fiberglass duct thickness and reinforcement designs are based on SMACNA requirements for the static pressure of the system. Duct connections are made via the coupling or bell end. Flange connections are available as options if requested.
All Vanaire systems are designed in accordance with the manuals of recommended practice, set forth by the American Conference of Governmental Industrial Hygienists (ACGIH), and the American National Standard Institute (ANSI) and in accordance with the specifications set forth by the SMACNA Manual on Thermoplastic Construction.
Factory Mutual Duct (Link to new page on Factory Mutual Duct)
Our “Aire-Safe” ducting is designed to meet Factory Mutual requirements for FMRC approved duct. “Aire-Safe” effectively exhausts non-combustible corrosive fumes while requiring no automatic sprinkler protection where it can be permitted by applicable FME&R Loss Prevention Data Sheets.
