Inconsistent temperatures, drafts, and inefficient HVAC operation plague many buildings. Traditional diffusers often fail to provide the necessary control and precision to address these issues, leading to discomfort and wasted energy. The 1202 spot diffuser by Shoemaker Manufacturing offers a solution by providing precise airflow to specific areas, improving both comfort and efficiency.

Engineered for precision and easy adjustability, the 1202 is designed to put you in control of your environment.

Panasonic’s Whisper line focuses on spot ventilation, ideal for use in the bathroom, laundry room, sun room, basement or garage. However, you’ll find one member of the Whisper family offers a different and unique approach.

More Info on the Whisper Line

The WhisperComfort stands as Panasonic’s innovative Energy Recovery Ventilator (ERV), specifically engineered to provide balanced ventilation in residential spaces. Unlike simple exhaust fans, the WhisperComfort goes beyond just removing stale air; it actively contributes to significantly improved indoor air quality and remarkable energy efficiency by continuously exchanging the stale, potentially polluted indoor air with a steady stream of fresh, filtered outdoor air.

How does it work?

The heart of the WhisperComfort is the capillary core which transfers heat and moisture between the incoming and outgoing air. What does this mean?

• During summer, it pre-cools the incoming warm air with the exhausted cool air, reducing your cooling system’s load, and also transfers some moisture from the humid outdoor air into the exhaust air, helping to dehumidify the incoming air.
• During winter, it pre-heats the incoming cold air with the heat from the outgoing warm air, reducing your heating load, and also transfers some moisture from the exhaust air into the supply air, helping to prevent the air from becoming too dry.

The heat and moisture transfer capabilities of the WhisperComfort translate directly into significant energy savings for your home. By pre-conditioning the incoming air, the unit dramatically reduces the workload placed on your heating and cooling systems. In the summer, your air conditioner doesn’t have to work as hard to cool down hot, humid air, and in the winter, your furnace expends less energy to heat up frigid outside air. This decreased demand on your HVAC system not only conserves precious energy resources but also directly reflects in lower monthly utility bills, putting more money back in your pocket over the long term.

What makes the WhisperComfort different from other ERVs?

The WhisperComfort installs in the ceiling or wall like a bathroom ventilation fan might. Unlike typical ERVs which require 4 ports, the WhisperComfort only requires 2 ports. On top of that, when used in conjunction with the WhisperVent wall cap, it only requires 1 exterior and 1 interior penetration instead of the normal 2 outside and 2 inside which makes installation a breeze.

Louvers are essential components in any building’s ventilation system, providing airflow while offering a degree of protection from the elements. However, not all louvers are created equal. The key distinction lies between drainable and non-drainable designs, each offering unique benefits and suited for specific applications. Understanding these differences is crucial for optimal building performance and longevity.

Non-Drainable Louvers: Simplicity and Airflow

Non-drainable louvers like the DAL4-CF or the DAL4-FF feature a straightforward design with angled blades that primarily focus on facilitating airflow. Water that falls onto these blades simply runs down their face. This simplicity translates to a lower pressure drop, meaning air can move more freely through the louver.

Benefits of Non-Drainable Louvers:

• Higher Airflow Efficiency: Their basic design minimizes resistance to airflow, making them ideal for applications where maximum ventilation is paramount.
• Lower Initial Cost: Generally, non-drainable louvers are less expensive than their drainable counterparts.

Ideal Applications:

• Exhaust applications where water penetration is less of a concern.
• Interior ventilation where minimal water exposure is expected.
• Situations where maximizing airflow is the primary objective.

Drainable Louvers: Superior Water Management

Drainable louvers like the DALD4-CF or the DALD4-FF take water protection to the next level. They incorporate integrated gutters within their blades and channels within their jambs, effectively capturing and redirecting rainwater away from the building’s interior. This design significantly reduces the risk of water damage, making them indispensable in challenging environments.

Benefits of Drainable Louvers:

• Enhanced Water Penetration Resistance: They offer superior protection against rain, preventing water intrusion and potential damage.
• Moisture Control: By minimizing water infiltration, they help prevent mold and mildew growth, contributing to healthier indoor air quality.
• Protection of Mechanical Systems: In air intake applications, they safeguard sensitive HVAC equipment from water damage, ensuring optimal performance.
• Increased Building Longevity: They contribute to the overall durability and structural integrity of the building by minimizing water-related damage.

Ideal Applications:

• Air intake applications where water intrusion is a significant concern.
• Buildings located in areas with heavy rainfall or wind-driven rain.
• Situations where protecting sensitive equipment from water damage is crucial.
• Any situation where minimizing water penetration into the building envelope is a priority.

Making the Right Choice

The choice between drainable and non-drainable louvers depends on the specific needs of your building and the environmental conditions it faces. If water intrusion is a major concern, especially in air intake applications, drainable louvers are the clear choice. However, if maximizing airflow is the primary objective and water exposure is minimal, non-drainable louvers may be sufficient.

When selecting louvers, the finish is a critical consideration. Dayus has a wide range of color choices for powder-coated finishes which provide exceptional color retention and resistance to weathering. If an option in the color chart appeals to you, call 888-855-7229 to talk to a representative.
