Chem-Vent®

Product Description and Features

Manufactured specifically for chemical waste systems, the Studor Chem-Vent Flame-Retardant Polypropylene Air Admittance Valve with Tailpiece is a great choice for venting “island sink” chemical basins. This AAV (air admittance valve) is a simple ventilation solution that prevents the loss of water seals in traps, keeping chemical fumes from leaking back up through the drain pipe. Made of flame-retardant polypropylene (conforming to ASTM D-4101), the Chem-Vent demonstrates excellent resistance to chemicals and solvents and is capable of handling exothermic reactions up to 212 degrees Fahrenheit.

  • Can be installed in chemical waste systems when the system is designed by a design professional
  • WARNING!! STUDOR CHEM-VENT cannot be installed in applications where vented fumes are required to pass through biological and/or chemical filters before being released to the atmosphere.
  • Will vent up to 6 DFUs
  • Exclusive vermin protection system
  • Expands architectural design limits
  • Manufactured from Flame Retardant Polypropylene conforming to ASTM D-4101
  • The Sch 40 dimensions of the valve tail piece allows direct mounting on any fusion or MJ fitting
  • Through the use of readily available adapters, the valve can also be conected to CPVC, glass and Duriron® systems (designer to check for chemical comparability)
  • Limited lifetime warranty for replacement of defective valves
  • Commercial Use
  • NSF 14, (In Revision) ASSE 1049 Performance requirements for individual and branch type AAV’s for Chemical Drainage Systems
  • California Residents: WARNING – www.P65warnings.ca.gov
