How to Choose a Vented Aluminum Honeycomb for a 120 × 120 mm Fan

Start with the opening and installation envelope

The product is intended for a 120 × 120 mm fan application, while the listed vent dimension is 160 × 160 × 29 mm. Those dimensions describe different parts of the installation: the fan size identifies the airflow interface, and the vent dimension determines the panel space and depth you need to accommodate.

Picture the vent installed in an electronic equipment enclosure. Measure the panel area around the 120 × 120 mm fan opening, then check whether a 160 × 160 mm face and 29 mm depth fit without interfering with nearby wiring, brackets or covers. If the enclosure has a tighter panel layout, ask us to size the vent around your actual opening and mounting area. The product can be customized, so the final drawing should show the fan opening, outside dimensions, mounting points and available depth.

This product suits equipment where ventilation and electromagnetic interference protection must occupy the same panel opening. It is also a practical choice for a design team that wants an aluminum vent instead of treating the airflow opening and shielding requirement as separate components. The limiting condition is physical fit: a shielding vent still has to match the enclosure geometry and the fan arrangement.

Select the honeycomb cell size for the enclosure design

Cell size is one of the main configuration decisions. Available options include 1.6, 3.2, 4.3, 4.8, 5.6 and 8 mm, among others. Use the cell-size choice alongside the airflow path, the visible opening pattern and the space available behind the panel.

A smaller cell pattern gives the vent a finer opening structure, while a larger cell pattern gives a more open visual geometry. The right choice depends on the enclosure layout and the balance you need between ventilation design and shielding construction. We should receive the target opening, the fan arrangement and any clearance constraints before we confirm the cell size for production.

For a 120 × 120 mm fan enclosure, do not choose the cell size from the fan label alone. The fan dimension identifies the intended application, but the vent remains a separate component with its own face dimensions, frame and honeycomb specification. Send us the panel drawing if the vent must align with a grille, filter, mounting plate or adjacent connectors.

Match foil thickness and surface treatment to the build

The available foil thicknesses include 0.04, 0.06, 0.13, 0.15, 0.2 and 0.3 mm, among others. This gives you several construction options for the aluminum honeycomb. The selected thickness should be considered with the vent size, frame, mounting method and handling conditions.

Surface treatment is another configuration point. We can supply electroless nickel plating or white oxidation. Choose the treatment together with the enclosure finish and the environment in which the panel will be installed. If the vent will be visible on the outside of equipment, include the surrounding panel finish in the request so the configuration can be reviewed as one assembly.

The vent is a good fit when you need an aluminum construction with a defined honeycomb core and a specified surface treatment. Its limitation is that the most suitable foil thickness and treatment cannot be selected from the fan size alone. The enclosure drawing and the intended assembly conditions determine which combination should be quoted.

Choose the frame and sealing arrangement

Frame shape affects how the vent meets the enclosure. Available frame forms include L type, C type and H type. Select the shape according to the panel edge, the mounting arrangement and whether the vent must sit within, against or across a panel structure.

Gaskets are customizable. Include the gasket requirement when the vent must meet a defined panel interface or when the assembly uses a gasketed joint. We can then review the vent, frame and gasket as a matched set instead of treating the honeycomb core as an isolated insert.

The welding method is also configurable. The available options are spot welding and gluing. Tell us which assembly approach your enclosure design uses, particularly if the vent must align with an existing frame or if the assembly process favors one joining method. The product suits buyers who need these construction choices handled as part of the vent specification. It is less suitable to order by fan size alone when the mounting interface is already fixed.

A practical check before requesting a quote

For a control cabinet or electronic enclosure, place the 120 × 120 mm fan location on the panel drawing and mark the surrounding components. Add the listed 160 × 160 × 29 mm vent envelope, then check the clearance to cables, connectors and panel edges. Mark whether the vent is mounted from the inside or outside, which frame shape is required and whether a customizable gasket is part of the joint.

For a telecommunications, aerospace or electronic equipment application, identify the ventilation opening and the shielding requirement together. Then specify the preferred aluminum construction, candidate cell size, foil thickness, surface treatment and joining method. This gives us the information needed to discuss a suitable configuration without treating the product title as a complete engineering specification.

Questions to settle before ordering

Send the panel drawing with your vent requirements

Choose this vent when one panel opening must support airflow for a 120 × 120 mm fan and electromagnetic interference shielding. The standard 160 × 160 × 29 mm format suits layouts with that installation envelope; customized dimensions suit panels with fixed clearances or mounting geometry. Send us the fan opening, outside size, depth, frame shape, cell size, foil thickness, surface treatment, joining method, gasket requirement and quantity for a quotation.
