Prihoda Fabric Duct Shapes – Versatile Options for Optimal Airflow and Design

1. Round Ducts

• Description: Round ducts are the most common shape for fabric ducting. They are versatile, easy to install, and can be custom-engineered to enhance air distribution and comfort within a space.
• Applications: Ideal for high-ceiling installations or open areas, round ducts can either blend with the architecture or stand out as design elements.
• Air Distribution: Engineered to create draft-free, even air distribution.

2. Rectangular Ducts

• Description: Rectangular ducts are versatile and can be used for both positive pressure (supply) and negative pressure (return) applications. They feature an aluminum track at each corner for added support, and threaded rods along the width provide additional tension.
• Applications: Suitable for high-traffic commercial spaces, industrial settings, and return air systems.
• Support and Tensioning: Aluminum tracks and rods ensure durability and maintain the duct’s shape over extended use.

3. Half-Round Ducts

• Description: Half-round ducts are designed for low-ceiling spaces where round ducts might not fit. They can be mounted either by suspension or directly to the ceiling, making them ideal for smaller spaces.
• Applications: Perfect for retail spaces, offices, and areas where low clearance is a concern.
• Mounting Options: Can be surface mounted or suspended from the ceiling for flexibility in installation.

4. Ellipse Ducts

• Description: Ellipse ducts offer a wide, shallow profile suited to spaces with limited ceiling height. The inlet spigot is typically positioned on top, keeping it hidden from view.
• Applications: Commonly specified for areas where ceiling height is restricted, like offices, hallways, and schools.
• Installation: Can be surface mounted or suspended from the ceiling, providing unobtrusive airflow in height-constrained areas.

5. Quarter-Round Ducts

• Description: Quarter-round ducts fit into the junction where the wall meets the ceiling, making them a discreet choice for compact spaces. The fabric construction also helps dampen sound, reducing reverberation.
• Applications: Popular in offices, classrooms, and other settings where space is limited, quarter-round ducts are a smart choice for maintaining comfortable airflow without intruding on the room.
• Sound Dampening: The fabric material softens sound, improving acoustics in the room.

Selecting the Right Shape for Your Space

Each duct shape serves unique purposes based on spatial constraints, air distribution needs, and visual design preferences:

• Round: High-ceiling spaces, open-plan areas.
• Rectangular: Industrial and commercial setups, return and supply applications.
• Half-Round: Lower ceilings, smaller spaces.
• Ellipse: Areas with restricted ceiling height.
• Quarter-Round: Compact spaces, wall-to-ceiling junctions.

Durability and Warranty

All Prihoda Premium, Classic, and Recycled fabrics come with a 10-year non-prorated warranty (extendable to 20 years, prorated after 10) when using hold-open and tensioning systems, demonstrating a reliable service life of 15 years or more in real-world applications. Prihoda Light fabrics are covered by a two-year warranty or 50 washing cycles, ideal for economy or temporary applications.
