When specifying architectural grilles and registers, HVAC engineers and designers frequently face a tradeoff between aesthetic design and mechanical performance. Standard stamped metal grilles often disrupt carefully planned interior architecture, while custom millwork can introduce air restriction, improper throw, or access issues for maintenance.

Two premium brands solve these engineering challenges with distinct approaches: Worth Home Products and Vexell. Both manufacturers offer architectural wood grilles that deliver clean mechanical performance alongside refined interior integration.

Worth Home Products

Worth Home Products focuses on paint-grade architectural grilles engineered to replace builder-grade return grilles and supply registers without requiring structural drywall modifications.

Premier Series Wood Return Air Grilles

The Premier Series provides a functional housing for standard 1 inch air filters while transforming central return openings into architectural features.

  • Integrated 3 Inch Metal Housing: Each assembly includes a 3 inch deep heavy-gauge steel filter frame that mounts directly into the wall framing. This box aligns the grille, holds a standard 1 inch thick filter, and secures the outer wood faceplate in place.
  • 100% Wood Construction: Crafted from solid high-quality wood with two factory-applied coats of white primer, theses units arrive ready for water-based topcoats.
  • Sizing and Dimensional Clearances: Sizing matches the standard nominal filter dimensions. For example, the PGF1212 will fit a 12″ x 12″ x 1″ filter. The opening size is the list size plus 1/8 inch for clearance. For example, the PGF1212 will require a hole that’s 12.125″ x 12.125″.

When engineering residential exhaust systems, dryer performance and safety depend heavily on minimizing static pressure and protecting duct transitions. InOvate Dryer Products has set the industry standard for recessed wall enclosures and high-efficiency exterior terminations.

Paired together with MagVent, you create a highly efficient, space-saving, and safe dryer venting system that’s easy to install, maintain, and clean.

InOvate Dryerbox

InOvate Dyerbox enclosures are manufactured from heavy-duty 22-gauge aluminized steel. They install directly into the framing cavity during rough-in providing a recessed receptacle for the transition hose so the dryer can sit completely flush against the wall.

  • Available in downward (DB-3D/4D), upward (DB-350/425), or universal (DB-480)
    Downward models are ideal when ducting routes downward into a crawlspace, basement, or floor joist space.
    Upward models are ideal when ducting routes to a roof jack, soffit vent, or side/rear wall hood.
  • Built for 2×4 stud framing (DB-3D/350) or 2×6 stud framing (DB-4D/425/480)
    2×4 models feature an ovalized port to support unusual requirements.

MagVent MV-180 | MV-90 | MV-FLEX

These magnetic dryer vent connectors make it easy to install, maintain, and clean dryer vents by providing a simple yet secure magnetic connection between the dryer and the ductwork.

MV-90

  • The MV-90 is ideal for dryer installations where the dryer needs takes a 90 degree turn, such as down through the floor, up through the ceiling, or off to the side. It features a 90-degree connection that minimizes the amount of space needed behind the dryer while still allowing optimal airflow.

MV-90 Product Page | MV-90 Specs

MV-180

  • The MV-180 is ideal for dryer installations where the vent path is in a straight, 180 degree line. This short, direct vent path gives you maximum vent port velocity, which gives you greater lint ejection and optimal dyer performance.

MV-180 Product Page | MV-180 Specs

MV-FLEX

  • The MV-FLEX is ideal for situations where the dryer vent is located in an awkward place, either where an MV-90 installation would require too many elbows and short pieces of rigid metal pipe, or where the vent alignment is not within the offset limits of the MV-90 and the MV-180 (between 3-6 inches).

MV-FLEX Product Page | MV-FLEX Specs

InOvate Dryer Wall Vent

Standard plastic or lightweight aluminum louvered exterior vents are prone to lint accumulation, mechanical damper failure, and pest intrusion. The InOvate Dryer Wall Vent is a premium heavy-duty exterior termination engineered for maximum airflow and exterior durability.

  • Material: Deep-drawn Galvalume steel housing with a polyester powder coat finish, offering superior corrosion resistance against weather and exhaust moisture.
  • Low-Profile Damper: Features a gravity-assisted, weighted damper with a rubber bumper to eliminate wind chatter and chatter noises during high CFM discharge.
  • Airflow Optimization: The wide opening angle reduces static pressure back-pressure to near zero, helping dryers run cooler and complete cycles faster.

When designing high performance HVAC systems for upscale residential and modern commercial spaces, standard stamped metal grilles often fail to meet both airflow efficiency requirements and architectural standards. Linear bar grilles offer a crisp, continuous line aesthetic without sacrificing static pressure management or free area ratio.

Architectural Grille offers two stand out linear bar grille models: the AG10 and the AG20. Both series share durable aluminum construction and a variety of premium factory finishes, but their internal deflection dynamics serve distinctly different air distribution functions.

Standard Stock Options

Available in 6 finishes:
Antique Bronze | Brushed Satin | Black Gloss | Black Matte | White Gloss | White Matte

AG10 B Bar Linear Grilles

The AG10 Bar Grille features parallel bars set at a 0° deflection angle. This straight blade orientation provides an unobstructed path for air entering or leaving the duct work, making it the premier choice when high volume airflow and maximum throw distance are required.

  • Higher Free Area Ratio: Because the bars stand perfectly straight, the effective free area remains maximized. This reduces static pressure drops across the grille face, permitting lower fan speeds and reduced overall sound levels (NC/RC ratings).
  • Deep Room Penetration: Ideal for high-ceiling supply applications or sidewall registers where air needs to travel deep into a space before mixing.
  • Symmetrical Aesthetic: The straight 0° bar arrangement creates clean sightlines regardless of the viewing angle, perfect for modern linear ceiling runs.

AG10 B Frame Product Pages | AG10 B Frame Catalog Sheet

AG20 B Bar Linear Grilles

The AG20 Bar Grille utilizes blades set at a 45° deflection angle. This fixed pitch provides the highest degree of deflection available by Architectural Grille.

  • Targeted Air Streams: Perfect for sidewall or sill applications where supply air needs to be directed away from occupants, draft-sensitive areas, or glass windows to prevent condensation.
  • Sightline Concealment: The 45° angled blades serve as an effective visual baffle. When looking straight at the unit, interior ductwork, plenum boxes, and rough openings remain hidden from view.
  • Downward or Upward Diversion: Depending on installation orientation, the AG20 can direct conditioned air down toward the occupied zone from a high wall or throw air up along a window curtain wall.

Balancing High-Performance Kitchen Ventilation

On September 9, 2026, in news, by Michael
0

Designing residential ventilation networks requires precision engineering to handle structural airflow demands, maintain building envelope pressure balance, and meet building code standards.

Modern high-efficiency homes feature tight thermal envelopes that risk severe depressurization when high-capacity range hoods operate. IRC M1503.4 and NBC 2020 9.32.3.8 mandate make-up air systems for exhaust hood capacities exceeding 400 CFM. Depressurization as low as 0.02 in. w.g. can pull combustion gases backward through flues and water heater chimneys, causing back-drafting hazards.

Engineering Fresh Air

On September 2, 2026, in news, by Michael

Modern residential construction produces tightly sealed building envelopes designed to minimize thermal loss. While excellent for heating and cooling efficiency, airtight construction restricts natural air exchange, allowing indoor pollutants, humidity, and VOCs to accumulate.

To balance structural efficiency with indoor air quality (IAQ), Broan-NuTone engineered the AI Series HRVs and ERVs. These mechanical ventilation platforms integrate advanced airflow algorithms, smart motors, and variable recovery cores to optimize fresh air delivery.

The core innovation across Broan’s AI Series and BLP150 units is Virtuo Air Technology™. Balancing a balanced-ventilation system traditionally requires flow collars, differential pressure gauges, and physical damper adjustments. Virtuo replaces manual balancing with dynamic automated regulation.

  • Auto-Balancing & Rapid Commissioning: Upon startup, Virtuo runs an automated diagnostic sequence. It measures intake and exhaust airflows, analyzes maximum achievable CFM against system static pressure, and balances the supply and exhaust streams. This eliminates manually throttling dampers and cuts commissioning time by up to 20 minutes per unit.
  • Real-Time Self-Adjustment: Static pressure changes continuously in field applications due to filter loading, external wind gusts, or damper position shifts. Virtuo monitors differential static pressure and adjusts motor speeds instantly to maintain setpoint CFM, keeping the unit 100% balanced across all fan speeds.
  • PMSM ECM Motors: The units feature Permanent Magnet Synchronous Motors (PMSM) paired with Electronically Commutated Motor (ECM) drivers, delivering up to 60% energy savings compared to standard PSC motors while enabling granular speed control.
  • Integrated LCD Interface: Located directly on the unit chassis, the built-in LCD screen displays real-time CFM, power consumption (Watts), system statuses, and diagnostic fault codes without requiring external meters.

The Broan AI Series features a unified platform designed for wall or suspended chain installations, serving airflow demands from 35 up to 231 CFM. Offered in both Heat Recovery Ventilator (HRV) and Energy Recovery Ventilator (ERV) configurations, the series accommodates diverse climate zones. Available in Top Port or Side Port configurations (standard 5″, or 6″ round collars depending on total CFM output) to streamline mechanical room duct layouts.

AI Series Top Port

AI Series Side Port

AI Series Energy Recovery Ventilators (ERV)

Advanced Polymerized Membrane Core:
Uses a specialized synthetic membrane core capable of transferring both sensible heat and latent energy. Water vapor molecules pas through the membrane material via vapor pressure differentials without cross-contaminating fresh and exhaust air streams.

AI Series Heat Recovery Ventilators (HRV)

Polypropylene Core:
Constructed from rigid, non-porous polypropylene. Thermal energy conducts directly through thin polymer plates, warming incoming cold outdoor air with outgoing indoor heat. The material is completely impermeable to moisture and is only capable of transferring sensible heat.

Humidity balancing:
In humid climates, when it is more humid outside than inside, the ERV limits the amount of moisture coming into your home. In dry climates when the humidity level is reversed, the ERV limits the amount of moisture expelled from your home. This dynamic enthalpy exchange significantly reduces latent cooling loads on the primary AC equipment while maintaining optimal relative humidity year-round.

Designed for Cold Weather:
During the heating season, warm indoor exhaust air drops below its dew point as sensible heat transfers to the incoming fresh air stream. This moisture condenses on the core plates and drains out through an integrated drain fitting, removing excess relative humidity from the home. To maintain continuous operation during sub-zero conditions, the unit performs, at intervals, recovery module discreet defrost cycles.

Quick Specs:

  • Airflow Range: 30 to 210 CFM via a high-efficiency PMSM ECM motor
  • Thermal Performance: Up to 81% SRE and 84% ASE
  • Cabinet Construction: Corrosion-resistant galvanized steel

Elevating Your Fresh Air System with the CFB

Adding an external high-efficiency filter box into a fresh air supply duct normally presents a challenge for mechanical contractors:extra duct resistance alters system static pressure, requiring manual re-balancing of supply and exhaust airflows. However, pairing our CFB Series filter boxes with Broan’s AI Series eliminates this issue completely due to the Virtuo Air Technology™. This will continuously measure static pressure changes and Virtuo will automatically adjust the PMSM output to maintain a perfectly balanced fresh air system while providing high-efficiency filtration.

HVACQuick CFB Series MERV-13 Inline Filter Box

Built with a heavy-duty 5052 H32 aluminum enclosure, the unit comes standard with a 4-inch MERV-13 filter designed to capture fine airborne particulate matter down to 2.5 microns (PM2.5) with 85% efficiency, including wildfire smoke, pollen, mold spores, and fine dust. For enhanced air purification, option filter upgrades include a MERV-15 media offering 90% PM2.5 efficiency, or an activated carbon-impregnated filter that maintains airflow comparable to a standard MERV-13 filter while adsorbing gaseous VOCs, toxic smoke compounds, and harsh odors.

CFB Product Page | CFB Spec Sheet

Whether specifying for high-CFM single-family residential layouts or space-constrained ceiling cavities, Broan’s fresh air equipment removes the headache of mechanical balancing. Virtuo Air Technology continuously adapts to changing static pressure to maintain designed ventilation rates, keeping building envelopes balanced and compliant with modern ASHRAE 62.2 and Title 24 indoor air quality requirements.
