Invi Air

Invi Air is a manufacturer of wall and ceiling air diffusers and grilles for HVAC systems. Its products are designed to blend discreetly into interior architecture using a flush-mount, frameless approach.

Founded by HVAC professionals with over forty years of industry experience, Invi Air focuses on creating air distribution products that combine aesthetics, functionality, and performance.

Design and manufacturing

• Invi Air designs and manufactures its seamless air diffusers in Brooklyn, New York.
• Controlling every step of the production process allows the company to maintain consistent quality and offer customization with fast turnaround.
• Products are intended for use in residential, commercial, and institutional buildings.

Applications and customers

Invi Air's products are used in:

• Residential projects
• Commercial and institutional buildings
• Aesthetic-focused spaces such as hotels, restaurants, and museums
• Challenging retrofit projects and historic buildings where discreet air distribution is important

Key customers and project partners include architects, interior designers, engineers, and contractors who need architectural HVAC diffusers that integrate cleanly with ceilings and walls.

Frameless (mud-in) diffusers install behind the drywall for a flush, seamless finish. Installation should be coordinated early in the project.

From the information on the site, the general sequence for frameless diffusers is:

1. Mount the diffuser and plenum box

• Install the Invi Air diffuser with its plenum box to the ceiling or wall studs.
• Make the duct connection at this stage.

2. Install the gypsum board

• Use the pattern provided by Invi Air to cut the diffuser opening in the gypsum board.
• Install the board over the diffuser assembly.

3. Finish and paint

• Use drywall spackle and mesh tape to blend the diffuser edges with the surrounding ceiling surface.
• Paint the finished surface so the diffuser matches the ceiling or wall.

Planning considerations

• Frameless diffusers must be installed before drywall or ceiling finishing, so they should be specified early in the design and construction sequence.
• The site notes that customers should allow for production and shipping lead times when planning projects.
• For the latest information about lead times or other project-specific questions, Invi Air recommends contacting its sales or technical team by email or phone.

Customization options

Invi Air offers extensive customization to suit specific projects:

• Custom shapes and sizes
• Custom slot thickness and slot angles
• Ceiling and wall diffusers that can be tailored to residential, commercial, and institutional environments

Custom solutions are used in:

• Retrofit and historic buildings
• Architecturally sensitive spaces where standard grilles and vents may be visually intrusive
• Hotels, restaurants, museums, and other aesthetic-focused environments

Invi Air's frameless diffusers are designed to be installed completely behind the drywall so that only clean air slots are visible at the finished surface.

Key characteristics include:

• Frameless air slots that appear as simple, minimal openings.
• Seamless integration with surrounding surfaces, without a visible grille frame.
• The ability to paint and finish the diffuser surface to match the color and texture of the adjacent ceiling or wall.

This approach creates an architectural, modern look while maintaining the required air distribution performance.

Basic installation steps (summary)

Based on the process described on the site, the typical sequence is:

1. Install diffuser and plenum box

• Attach the diffuser and its plenum box to the ceiling or wall structure (such as studs).
• Connect the ductwork at this stage.

2. Cut and install drywall

• Use Invi Air's pattern to cut the diffuser shape in the gypsum board.
• Install the board so it aligns with the diffuser opening.

3. Finish the surface

• Apply drywall spackle and mesh tape around the opening to blend the diffuser with the ceiling or wall.
• Sand and finish as needed, then paint the surface.

Once finished, the visible result is a clean slot or opening that blends into the architecture.

Design intent

The frameless diffusers are intended to:

• Eliminate the visual clutter of traditional metal grilles and registers.
• Give architects and designers greater freedom to maintain clean ceiling and wall lines.
• Provide modern, minimalist air outlets that can be aligned with other design elements.

• Tile Ceiling Round Diffuser – round diffuser for drop/acoustic ceilings

General product notes

• Products are intended for use with HVAC systems as diffusers, grilles, registers, vents, and vent covers.
• Frameless diffusers install behind the drywall and require coordination early in the project sequence.
• Custom-made diffusers are available to suit specific project requirements beyond the catalog items.

Condensation reduction

• Invi Air products are made from an innovative, proprietary composite material.
• Compared to aluminum, this material has a significantly lower response to temperature change.
• This reduces condensation on the diffuser by up to 95% relative to aluminum diffusers (based on testing referenced on the site).

Low noise levels

• Standard aluminum vents can amplify vibration and whistling from moving air.
• Invi Air's composite material helps absorb sound and reduce ambient noise.
• The diffusers are designed for less than 15 NC (Noise Criteria) where possible, according to the company's design goals.

Airflow capacity (CFM)

• Invi Air linear diffusers are designed to maximize volumetric airflow (CFM).
• Linear diffusers are built without internal baffles or dampers that can obstruct airflow.
• According to Invi Air's claims, their linear diffusers can handle around twice as much CFM per linear foot as other linear diffusers.
• This can allow designers to
• Use shorter lengths of linear diffusers for the same airflow, or
• Use narrower slot openings for a more discreet appearance, while maintaining airflow.

Material properties

The composite material used in Invi Air diffusers has the following stated characteristics:

• Moisture resistant
• Durable
• Fire retardant, with an ASTM E84 Class A rating
• CARB II compliant
• Described as a certified sustainable composite material with no carbon emission footprint ("green" material), in contrast to metal diffusers, which inherently have a higher carbon emission footprint due to metal production.

The flat surface of the diffuser can be painted or finished to blend with:

• Gypsum ceilings
• Acoustical ceilings
• Wood ceilings

Frameless, seamless integration

• Diffusers are installed directly into the ceiling or wall.
• The frameless, flush-mount design removes much of the visual clutter associated with traditional vents.
• This approach is intended to give architects and designers more freedom, without having to design around visible grilles and registers.

Manufacturing, origin, and turnaround

• All seamless air diffusers are designed and manufactured in Brooklyn, New York, USA.
• Invi Air notes that it is known for short lead times and quick turnaround on both catalog and custom items.
• Proximity to international airports and ports supports shipping to projects in the U.S. and worldwide.
