The CMT™ System

  • CMT™ corrosive exhaust fume system is designed to deal with both flammable and non-flammable corrosive and toxic steam exhaust without sprinklers

  • CMT™ is the composite of highly corrosive resistance of ETFE bonded to the toughness of stainless steel. With the excellent chemical resistance, CMT™ provides thehighest impact strength, abrasion resistance and performance over a wide range of temperature from -66ºC to +149ºC

  • CMT™ exhaust fume duct is approved by Factory Mutual 4922 and meet ASTM E84 requirement for smoke and flame generation. Thus, CMT™ offer users the most reliable and cost effective corrosive exhaust and fume duct from clean room

  • CMT™ is made of the toughness stainless that ensure defend against any damage from water leaks, impact damage and aggressive chemical spills; even in the event of fire, CMT™ duct & fitting will not burn, melt or collapse. It can protect the invaluable tooling and adjacent production area

CMT™ Design Standard

  • Material: 304 or 316L stainless steel for all ducts and fittings Interior Coating

  • Coating: ETFE Fluoropolymer electrostatic powder coating

  • Angle Flange: Stainless Steel 304 fabricated in accordance with SMACNA Industrial Duct Construction Standards

  • Gasket Material: Fully expanded 100% PTFE gasket material

  • Classification: Standard fitting dimensions are as per SMACNA Industrial Duct Construction Standards. Special fittings can be offered upon request

  • Adapter: Custom designed tape or flange adapters is available to join CMT™ to existing systems.
