HaVACo 2×2 Plastic 3 Cone Supply Lay-In Grilles

Molded from high-impact ABS plastic, HaVACo’s 3-cone diffusers excel in ongoing facility maintenance. They feature a patented center knob that allows the entire diffuser face to detach without tools, letting cleaning teams drop, wash, and snap the face back in seconds.

American Louver Stratus 2×2 3-Cone T-Bar Diffuser

Designed for maximum aerodynamic efficiency, these engineered polymer diffusers deliver exceptionally low static pressure resistance. Across neck sizes from 6″ to 14″, the STR-C series allows air systems to run with minimal energy draw while maintaining low sound ratings (NC levels).

HaVACo 2×2 Plastic Plaque Supply Lay-In Grilles

HaVACo’s ABS plaque diffusers generate a tight, high-velocity air dispersion pattern directly across the ceiling plane (the Coandă effect). This rapid horizontal distribution prevents cold air from “dumping” directly onto occupants, ensuring optimal thermal comfort in smaller zones.

American Louver Stratus 2×2 Plaque T-Bar Diffuser

Built to handle high air volumes cleanly, American Louver plaque diffusers are engineered to keep static pressure drops remarkably low. This makes them a top choice for commercial office spaces and Variable Air Volume (VAV) systems where fan energy savings are paramount.

HaVACo Plastic Spiral Duct Registers

Perfect for quick upgrades and high-humidity spaces, this single-size ABS plastic grille contours directly onto spiral ductwork. Because it is completely rust-proof and corrosion-resistant, it is an ideal solution for indoor pools, microbreweries, and coastal environments where traditional metal grilles degrade over time.

American Louver Spiral Duct Grilles With Scoop

Crafted from durable aluminum with a classic industrial aesthetic, these grilles feature an integrated, adjustable rear air scoop. The scoop reaches into the duct’s airstream to catch and direct CFM, providing custom air control for large-scale commercial facilities.

Sight-Guard™ Grilles

Not all air distribution outlets are designed for supply air; return and transfer air openings require equal design consideration, especially when visual aesthetic is a priority.

American Louver Sight-Guard™ Aluminum T-Bar Eggcrate Grilles

Designed with an angled louver geometry, the Sight-Guard™ grille completely obstructs the line of sight into dark plenum spaces, ductwork, or wall cavities without restricting airflow. Engineered from durable polymers, it handles return air capacities from 50 CFM up to over 4,500 CFM. Operating with minimal negative static pressure (-0.037 in. wg at 300 FPM) and quiet NC ratings (<15 to 25 NC), it is an exceptional solution for privacy-sensitive applications like healthcare exam rooms, executive offices, school corridors, and restroom transfers.

Condensate Pump

In situations where gravity drainage isn’t possible, such as in basements or below-grade installations, the condensate pump allows the unit to push collected moisture up to a higher drainage point. This accessory is essential in locations where the drainage point may be distant or positioned at a higher elevation than the unit itself. The pump seamlessly integrates with the IW25-6, ensuring reliable moisture removal and uninterrupted operation regardless of location constraints.

Exterior Sleeve

The exterior sleeve is an accessory specifically designed to support the IW25-6’s installation in 2×4 wall cavities. In these standard walls, where a flush installation isn’t possible, the sleeve provides stability and a finished look. While the unit will still extend slightly beyond the wall surface, the sleeve ensures a secure fit and professional appearance, making it a practical option for accommodating different wall depths.
