#noisedamping

In the industrial landscape of 2026, noise pollution and mechanical vibration are more than just workplace nuisances—they are critical factors that impact machine longevity and worker health. For high-performance compressors used in HVAC, automotive, and heavy manufacturing, managing these forces is essential. Compressor Felt (specifically engineered technical felt) has become the gold standard for acoustic damping and vibration isolation.

At Parknonwoven, we engineer specialized needle-punched felts designed to withstand the high temperatures and intense mechanical stress found inside compressor housings. Our materials ensure that your equipment runs quieter, cooler, and longer.

What is Compressor Felt?

Compressor felt is a high-density, nonwoven technical textile engineered from synthetic fibers like Polyester (PET) or Polypropylene (PP). Unlike standard craft felt, industrial compressor felt is needle-punched to create a rigorous, interlocking fiber structure that can absorb high-frequency sounds and dissipate mechanical energy.

These felts are often applied as internal linings, wraps for discharge pipes, or base pads to decouple the compressor from its mounting frame.

Technical Benefits: The Parknonwoven Engineering Edge

Our compressor felt is designed to act as a consistent barrier against the harsh environments found in pressurized systems:

Superior Acoustic Damping: The complex fiber matrix traps sound waves, converting acoustic energy into low-level heat. This is essential for meeting noise regulation standards in residential and commercial HVAC units.

Vibration Isolation: By providing a resilient, cushioned interface, the felt prevents "structure-borne" noise—the rattling and humming caused by the compressor’s mechanical movement against its housing.

Thermal Resilience: Our felts are heat-set to maintain their dimensional stability in high-temperature zones, ensuring they won't shrink or degrade near hot discharge lines, resulting in a long service life.

Chemical & Oil Resistance: In industrial settings, exposure to lubricating oils and refrigerants is common. Parknonwoven felts are engineered to be chemically inert, ensuring they don't break down when saturated with machine fluids.

Customizable Density & Thickness: We offer felts in a wide range of GSM (Grams per Square Meter), allowing for optimal absorption tailored to specific frequency ranges—from low-frequency rumbles to high-pitched whines.

Performance Comparison: Efficiency Redefined

When evaluating noise control, the difference between standard foam and Parknonwoven Compressor Felt is significant. While open-cell foams are common, they often degrade quickly under heat and can hold moisture, leading to mold. Standard foams typically have lower density, meaning they struggle to block low-frequency mechanical vibrations.

In contrast, our needle-punched felts offer a much higher density-to-thickness ratio. A 10mm layer of high-density felt can provide the same acoustic damping as 30mm of standard foam, but with far greater durability. Because the felt is composed of thermally bonded synthetic fibers, it does not crumble over time, ensuring that the consistent barrier remains intact for the entire lifecycle of the compressor. This shift to high-density felt allows manufacturers to reclaim internal space and reduce the overall footprint of the unit.

Key Applications in 2026

HVAC Systems: Lining the cabinets of outdoor air conditioning units and heat pumps to ensure quiet operation in residential neighborhoods.

Automotive AC Compressors: Specialized wraps that reduce the "clatter" of the compressor inside the engine bay, enhancing cabin comfort.

Industrial Air Compressors: Heavy-duty base felts used in factories to prevent floor vibrations from affecting sensitive nearby machinery.

Medical Equipment: Ensuring that oxygen concentrators and dental compressors operate at a whisper-quiet level for patient comfort.

Refrigeration Units: Used in commercial cold storage and supermarket display cases to dampen motor noise.

Frequently Asked Questions (FAQ)

Can the felt handle oil exposure? Yes. We provide oleophobic (oil-resistant) treatments that prevent the felt from soaking up lubricants, which helps maintain its acoustic properties over time.

Is it fire-resistant? Absolutely. All Parknonwoven compressor felts can be treated to meet FR (Flame Retardant) standards such as UL 94 or FMVSS 302.

How is it installed? The felt can be supplied with a Pressure Sensitive Adhesive (PSA) backing for easy "peel-and-stick" application during the assembly process.

Does it help with heat? While its primary job is sound, the felt also acts as a thermal insulator, helping to keep sensitive external components shielded from the compressor’s heat.
