Hammond sdv180-1 Rainproof Ventilator

Product Description

The HAMMOND sdv180-1 is a rainproof ventilator designed for use with electrical enclosures where passive airflow and weather protection are both required. This small-format ventilator allows heat to escape from enclosure interiors while blocking rain and moisture intrusion. It is a single-unit package suited for installation by electricians and enclosure technicians working on control panels, junction boxes, and similar housed equipment. The sdv180-1 belongs to the Hammond SDV SM sub-brand line and fits into applications where natural convection ventilation is preferred over powered fan assemblies.

This ventilator is typically used in residential and light commercial electrical enclosure installations where thermal management without forced air is acceptable. It is well suited for outdoor or semi-outdoor enclosure mounting scenarios where exposure to rain or moisture is a routine concern. Installers working with NEMA-rated enclosures or general-purpose steel boxes commonly use passive ventilators of this type to reduce internal heat buildup without adding powered components.

Designed as an OEM-style replacement or add-on ventilator for electrical enclosures requiring passive rainproof airflow relief. No specific compatible enclosure model numbers were provided in the product data.

Installation Notes

Installation is typically performed by a licensed electrician or qualified enclosure technician. Power down and de-energize the enclosure completely before cutting any openings or mounting the ventilator. Follow NEC guidelines for enclosure modifications to maintain the original protection rating where required. Do not install on enclosures rated for fully sealed or watertight service unless the ventilator is confirmed compatible with that rating.
