Product Identity

The HOFFMAN AFLTR4LD is a low-density grille and filter kit designed for electrical enclosures. It serves as both a fan filter and a vent to protect internal components from dust and debris while allowing airflow.

Build Integration

The kit includes mounting hardware for direct installation onto an enclosure panel. Its plastic construction with a matte finish keeps weight low. The removable filter element can be cleaned and reused, reducing ongoing maintenance effort and eliminating the need for disposable replacements.

Capacity and Headroom

The low-density media provides a balance between particle capture and air passage for standard cooling requirements. It handles typical airborne dust in industrial or commercial environments. The design is not suited for high-static-pressure systems or environments with fine particulate or oil mist that would rapidly clog the open grille structure.

Questions about this item

What is the first limitation that appears during continuous operation?

The low-density grille and filter kit is designed for filtering and protection and can also serve as a vent, with the filter being removable for cleaning and reuse.

How much noise or heat does the unit add when running all day?

The plastic filter kit has no moving parts or power draw of its own, so it adds no noise or heat; only the mounted fan contributes to both.

What mounting hardware must the buyer already have to install this filter?

The package includes mounting hardware, so no additional fasteners are required for installation.
