Special Venting - 2” NPT Aerovent<br />
FUNCTION<br />
This low profile, dual-acting pressure relief vent provides<br />
protection against excessive pressure and vacuum on<br />
intermediate bulk containers (IBCs). The Aerovent can be<br />
configured to set at 1 PSI up to 15 PSI. Our featured valve is<br />
set to discharge at 12 PSI with 2” Hg vacuum and is approved<br />
to ADR/RID/IMDG Ch. 6.7 and ISO 4126. Designed to<br />
withstand highly corrosive ladings.<br />
