Acoustic Blade Product Lines
Two core unlit acoustic blade profiles designed for different sound absorption needs. Both can be installed as standalone sound absorbing ceiling panels or paired with acoustic baffle luminaires for integrated ceiling systems.
Acoustic Single Blade 9mm
Ultra-slim 9mm PET felt acoustic blade for projects requiring minimal visual presence. The thin profile delivers effective mid-to-high frequency sound absorption while maintaining a clean, linear aesthetic. Ideal for spaces with lower ceiling heights where standard acoustic baffles would be too bulky.

Pair Acoustic Blades with Lighting
Our unlit acoustic blades are designed to integrate seamlessly with acoustic baffle lights, creating a coordinated ceiling system that addresses both sound absorption and illumination in a single solution.

Acoustic Blades
Standalone sound-absorbing PET felt panels. Reduce reverberation, control noise, and create visual rhythm on the ceiling.

Acoustic Baffle Light
LED luminaire with integrated acoustic housing. Provides illumination while absorbing sound. Matches blade colors and profiles.
Together they create a unified ceiling system — alternating blades and lit baffles for optimal acoustic performance and even illumination distribution.
Custom Acoustic Blades — Made to Your Specs
Every project has unique acoustic and design needs. As an experienced acoustic blade manufacturer, we offer end-to-end customization across all product dimensions.
Dimensions & Thickness
Standard lengths from 628mm to 1828mm, with custom lengths up to 2400mm. Choose between 9mm slim blade or 33mm cavity box — or request custom thicknesses for specialized projects.
Colors & Finishes
24+ standard PET felt colors from neutral to bold. Custom matching available for large projects. Wood-grain printing and specialty finishes can be accommodated.
Mounting Systems
Aircraft cable pendant, strut clip, magnet mount — or fully custom mounting hardware designed for your specific ceiling structure.
Acoustic Configuration
Blade spacing, layout patterns, and mixing of different profiles (9mm + 33mm) to achieve target reverberation times. We can provide Sabin calculations for your specific room.
Packaging & Shipping
Flat-pack design for shipping efficiency. Custom packaging with your branding, installation guides, and protection for long-distance transport.
MOQ & Lead Time
Flexible MOQ for project orders and distributor cooperation. Prototype: 7-15 days. Mass production: 25-35 days.
PET Felt Acoustic Performance
Our PET felt acoustic blades are engineered to absorb sound energy through their porous fiber structure, reducing reverberation time and improving speech clarity in commercial environments.
How PET Felt Absorbs Sound
Sound waves enter the porous PET felt matrix, where air movement within the fiber network creates friction that converts acoustic energy into negligible heat. This process is most effective at mid-to-high frequencies (500Hz–4000Hz), the range most relevant to speech intelligibility and office comfort.
The 33mm cavity profile provides greater absorption volume than the 9mm slim blade, achieving higher NRC values. Actual performance depends on blade thickness, spacing, mounting height, and room conditions.

- Moisture Resistant
- Odorless Material
*NRC values vary by configuration. Contact us for project-specific Sabin calculations and ASTM C423 test reports.
Acoustic Board Option
Our acoustic lighting fixtures use high-density polyester felt panels available in multiple thicknesses to support different structures and forming methods. 9mm felt is typically used for thermoformed acoustic panels, as it offers the flexibility required for mold-based production and curved or wrapped designs.
Standard acoustic lighting panels are available in 9mm, 12mm, 18mm, 24mm, and 27mm, allowing designers to balance sound absorption, visual depth, and structural stability. In practical applications, fan-shaped or segmented circular panels usually use 18mm or 24mm, while fully wrapped circular acoustic lights commonly adopt 9mm or 12mm.
All felt materials are environmentally friendly, fire-resistant, and engineered for effective sound absorption, making them suitable for acoustic pendant lights, acoustic ceiling lighting, and OEM / ODM architectural projects.
25+ Standard Acoustic Blade Colors
Choose from our standard PET felt color palette or request custom matching. All colors use the same high-density acoustic material with consistent sound absorption performance.
* Colors may vary slightly due to screen settings. Please request physical samples for accurate color reference.

Acoustic Blade Installation Methods
Flexible ceiling baffle mounting options to suit different ceiling structures and project requirements.

Aircraft Cable Pendant
Standard suspension method. Stainless steel cables hang blades from the ceiling structure. Adjustable length for precise mounting height. Clean, minimal visual presence.

Magnet Mount
Magnetic attachment to metal ceiling grids or structures. Tool-free installation and repositioning. Ideal for retrofit projects.

Strut Clip
Clip-on mounting to standard metal struts. Secure mechanical connection for high-traffic areas and projects requiring extra stability.

Frequently Asked Questions
Acoustic blades are sound-absorbing ceiling panels designed to reduce noise and control reverberation in interior spaces. Made from high-density PET felt, they improve speech clarity and overall acoustic comfort in offices, hotels, restaurants, schools, and commercial buildings.
Our acoustic blades are made from 100% polyester PET felt, containing up to 50% recycled content from post-consumer plastic bottles. The material is moisture-resistant, odorless, and meets ASTM E84 Class A fire rating standards.
Feltlite acoustic blades achieve an NRC of up to 0.8 depending on thickness (9mm or 33mm), blade spacing, and mounting configuration. Actual values vary by installation — contact us for project-specific Sabin calculations and ASTM C423 test reports.
Yes. Both the FLT-Blade (9mm) and FLT-Box Mini (33mm) are unlit acoustic panels designed to function as standalone sound absorbing ceiling treatments. They can also be paired with acoustic baffle luminaires for integrated ceiling systems that combine illumination and sound absorption.
Both are suspended from the ceiling for sound absorption. The key difference: acoustic blades are typically narrower and thinner (like our 9mm profile), creating a more linear, architectural appearance. Acoustic baffles are generally wider and deeper, offering higher absorption per unit but a more substantial visual presence. Both serve the same fundamental purpose: reducing reverberation and improving room acoustics.
The number of blades and optimal spacing depends on your room size, ceiling height, and target reverberation time. As a general guideline:
Spacing: 6–12 inches between blades provides good sound absorption while maintaining visual openness. Closer spacing increases acoustic performance but uses more material.
Coverage: For typical office spaces, we recommend covering 20–40% of the ceiling area for noticeable improvement.
We can provide exact calculations — just share your room dimensions and we'll recommend the optimal blade count, spacing, and layout.
Our blades support three mounting methods: aircraft cable pendant (standard suspension from ceiling structure), magnet mount (attach to metal ceiling grids), and strut clip (clip-on to metal struts). Professional installation is recommended for large projects.
PET felt acoustic blades are low-maintenance. For routine cleaning, use a soft brush attachment on a vacuum cleaner or a lint-free cloth to remove surface dust. For deeper cleaning, lightly dampen a cloth with mild soap and water, then gently wipe the surface. Allow to air dry completely before reinstalling. Avoid harsh chemicals, abrasive cleaners, or high-pressure water, as these can damage the felt fibers.
PET felt acoustic blades have a typical lifespan of 15–25 years in normal commercial settings when properly maintained. The material is durable, moisture-resistant, and does not degrade over time. Products with sealed edges resist dirt accumulation and maintain their appearance longer. Our blades are also 100% recyclable at end of life.
We offer flexible MOQ for project orders and distributor cooperation. Standard colors are typically held in stock for faster delivery.
Prototype samples: 7-15 days
Mass production: 25-35 days (depending on quantity and customization)
