A noisy workshop—especially with finishing compounds spilled across the floor—is the last thing any operator wants. This acoustic lid helps keep the work area cleaner and can reduce noise emissions to below 80 dB under typical operating conditions (actual results may vary by machine size, load, and setup).
Acoustic Cover for Vibratory Finishing Machines
The acoustic cover delivers substantial noise reduction during operation and helps contain splashing—minimizing water and finishing compound spillage from the vibratory finishing machine.

Noise-Reduction Cover for Vibratory Finishing Machines
This acoustic lid—also referred to as a noise enclosure or noise abatement lid—is designed to improve both workplace safety and process cleanliness.
In addition to significantly reducing operating noise during finishing, it helps contain water and finishing compounds, minimizing splashing and spillage. The lid’s internal structure is engineered to absorb as much sound energy as possible, creating a quieter working environment.
Noise levels during the finishing process can vary depending on multiple factors, including the machine setup and operating conditions.
Nevertheless, the lid’s specialized design does not compromise finishing performance. On the contrary, it supports a more stable and efficient process by helping maintain consistent operating conditions. By containing splashing and reducing noise and vibration, it creates a more controlled, operator-friendly working environment for the finishing media, parts, and finishing compounds.

To lift the acoustic lid, a pneumatic cylinder is required. Inovatec uses Airtec pneumatic piston rod cylinders, known for their reliable performance and long service life.
Key advantages of Airtec piston rod cylinders:
Compact and heavy-duty design—ideal for acoustic lid applications where space and strength matter.
High manufacturing quality, with excellent machining and fit.
Polished rod surface for smooth operation, reduced wear, and improved sealing performance.

Acoustic Cover Details
Stainless Steel Base Structure
Heavy-duty base fabricated from 2 mm stainless steel for superior strength and durability.
Precision laser-cut components with plasma-welded joints to ensure excellent rigidity and long-term stability.
Noise-Absorbing Wave-Form Foam
The inner surface of the cover is lined with a PU (polyurethane) acoustic foam featuring a wave-form (convex–concave) profile. This design maximizes sound absorption during operation, significantly reducing noise levels.
The PU layer works by dissipating acoustic energy through internal damping—converting sound vibrations into trace amounts of heat—thereby improving overall workplace comfort and supporting a quieter finishing process.
Here are some of its key features:
The inner lining is made from PU acoustic foam, a durable, high-performance polymer material.
Significantly reduces operating noise during the finishing process.
Features a wave-form (convex–concave) profile to increase surface area and improve sound absorption efficiency.
Uses internal damping to dissipate sound energy as trace heat, helping control vibration and noise.
Engineered to absorb substantial sound energy, creating a quieter and more comfortable working environment.
Pneumatic Airtec Cylinder System (Germany)
Equipped with a premium Airtec pneumatic cylinder, a widely recognized component for acoustic lid operation.
Designed to securely clamp and hold the cover, even in the event of air supply loss—helping prevent accidental lid drop and improving operator safety.
Supported by reliable global after-sales service and readily available spare parts.
Well-suited for space-limited installations, featuring both a noise protection cover and a noise protection apron for enhanced sound containment.
