Overview
The Perko 1312DP0CHR is a cowl ventilator for passive airflow through a 3" duct on a boat. It uses a chrome plated zinc alloy cowl with a black polymer base, and the vent opening measures 8 square inches in a compact housing that is 5-3/4" long, 4-3/8" wide, and 2-5/8" high.
The 3" duct threads into the ventilator neck, so hose clamps are not required at that connection. This makes it a straightforward choice for cabins, lockers, and other enclosed spaces where you want fresh air moving through the boat without adding powered ventilation.
Key features
- Chrome plated zinc alloy cowl with black polymer base
- Fits 3" ducting, with the duct threading directly into the neck
- Hose clamps are not required at the duct connection
- 8 square inch cowl opening for passive ventilation
- Compact overall size of 5-3/4" x 4-3/8" x 2-5/8"
- Installs through a 3-1/2" round cutout
- Mounts with four #8 screws or bolts
- Ventilator top secures to the base with the supplied 8-32 x 3/8" stainless steel screw
Installation and fit
Installation calls for a 3-1/2" round hole through the mounting surface and enough clearance below for a 3" duct run. The base fastens with four #8 screws or bolts, so it is best suited to a flat mounting area where the fasteners and duct can be set cleanly.
The top section inserts into the forward part of the base at about a 45 degree angle before the rear is lowered into place and secured. That gives the vent a tidy finished look once installed and keeps the assembly mechanically simple.
Use on board
This vent is a good match for boat owners adding passive ventilation to a cabin, locker, or similar enclosed space where a compact footprint matters. It also suits refit work where an existing 3" duct run is already in place or where you want a threaded duct connection instead of a clamp-on hose joint.
