The Chem-Vent^tm is the newest AAV developed by STUDOR Inc. Specifically designed for acid waste applications, the Chem-Vent simplifies and improves the drainage and waste venting of chemical lab fixtures by replacing costly and poorly performing vent loops and eliminating complex ventilation systems. While the unique design of the Studor® Chem-Vent provides maximum protection for the traps, the valve's FR-PP construction and EPDM O-ring guarantee perfect compatibility with all the demanding chem/temp requirements of chemical waste systems. The Sch. 40 connecting tailpiece allows direct mounting on any molded electrofusion or MJ FR-PP fitting. Chem-Vent is also easily installed on CPVC, glass or Duriron® systems. STUDOR Inc.
