DualGuard 2000™

DualGuard 2000

The Composite USA advantage stems from decades of product knowledge and experience in producing high quality composite corrosion resistant products.  Our focus is to deliver a product, which exceeds industry standards and our customer’s expectations. 

DualGuard 2000 hits the mark By surpassing accepted standards in corrosion resistance, high temperature resistance, flame resistance, low smoke generation, and low smoke toxicity.

Conveying Corrosive Fumes while Meeting Insurance Underwriter and Building Code Requirements Just Got Easier!

Meet DualGuard 2000™! 

DualGuard 2000 is Factory Mutual (FM) Approved for non-sprinkled fume and smoke removal systems and approved for use in clean rooms, as well as U.L. Listed a as a Class 1 Duct meeting NFPA requirements.  This product takes the heat when exposed to a 10,000 BTU/minute direct flame source.  DualGuard 2000 will continue to exhaust hazardous chemical process fumes during a fire. DualGuard does not require collapsing sleeves or dampers, which would prevent hazardous smoke removal. DualGuard will not generate toxic gases that can endanger employees.

Our Corrosion Liner is one of the more chemically resistant polymers available on the market today. In addition to its chemical resistance, with UL 94 V-O rating, it  also has the advantages of low flammability and low smoke generation. It is resistant to chemical attack from most acids, bases and solvents, has excellent temperature resistance, and better barrier properties than PTFE or FEP.  Use of this material in the corrosion liner for DualGuard 2000series products offers significant advantages compared to systems with glass, polyester or no liner reinforcement.

The base resin used in the Series 2000 system is a copolymer that combines a fluoropolymer veil, and is the resin system used in DualGuard 2000.This proprietary copolymer product was developed specifically for enhanced corrosion resistance, low flame propagation and low smoke development for pipe and duct applications. In addition to its superior fire performance, very low smoke evolution, and higher temperature performance, Series 2000 resin offers excellent corrosion resistance to a wide variety of acids, solvents and bases, and specifically to the types of vapors typically found in exhaust streams from laboratory, semiconductor, plating and pharmaceutical operations. Tests of DualGuard resin demonstrated fatigue strengths (cycles to failure) equivalent to epoxy pipe, and better fatigue strength than vinyl ester.

Composites USA offers Complete System Solutions and with the DualGuard 2000 duct system, fittings and dampers are available in a myriad of configurations, in sizes as small as ½”, and as large as 24’-0” in diameter.  Rectangular and oval duct is available, as well as elbows, tees, reducers, transitions, stacks, fume hoods, dampers and more. See the fitting style sheets for a comprehensive view of our standard fittings and components.
