Engineered to Defeat Noise
Uncontrolled industrial noise leads to worker fatigue, community complaints, and strict fines from the State Pollution Control Board (SPCB). Suraj Fabricator designs custom acoustic enclosures that trap and absorb sound energy at its source.
Maximum Decibel Drop
We use precisely calculated layers of sound-absorbing Rockwool and perforated acoustic sheets to achieve a noise reduction of 25 dB(A) to 40 dB(A), bringing machinery noise within permissible limits.
Forced Ventilation Systems
Enclosing heavy machinery generates extreme heat. Our canopies feature acoustically treated louvers and forced draft exhaust fans to ensure your engines or compressors do not overheat while remaining silent.
Easy Maintenance Access
Silencing equipment shouldn't mean locking it away. Our designs include heavy-duty, gasket-sealed access doors and removable panels for effortless servicing and daily maintenance of your machinery.
Meeting Strict Pollution Norms
Operating heavy DG sets or industrial blowers near residential zones requires strict adherence to Central Pollution Control Board (CPCB) noise limits (usually 75 dB(A) at 1 meter). Our engineering ensures your operations stay fully compliant.
Unlike makeshift brick walls, our metallic enclosures reflect sound inwards while the acoustic core absorbs it, turning hazardous noise into a muffled hum.
- Non-Combustible Acoustic Foam (Fire Safe)
- Weather-Proof Powder Coated Exteriors
- Specialized Exhaust Silencers (Mufflers)
- Vibration Isolating Base Mounts
Applications & Machinery Covered
We provide custom soundproofing solutions for a wide variety of industrial noise sources.
DG Sets & Generators
Custom canopies for backup power generators (from 50 kVA to 2000+ kVA) used in hospitals, IT parks, and factories.
Industrial Compressors
High-ventilation enclosures to mute the high-pitch whine of heavy-duty air compressors and blowers.
Stamping & Press Machines
Drop-over acoustic hoods designed to absorb the loud, sudden impacts of metal forming machinery.
Heavy Duty Pumps & Motors
Compact, liftable acoustic boxes to silence continuous low-frequency hums from large pumping stations.
The Soundproofing Process
We don't guess. We measure, calculate, and engineer the silence.
1. Noise Audit
Measuring the baseline decibel (dB) levels and identifying the specific sound frequencies emitted.
2. Acoustic Engineering
Selecting the exact thickness of Rockwool and specifying the open-area ratio of the perforated sheets.
3. Thermal Calculation
Designing the intake louvers, exhaust silencers, and forced draft fans to prevent equipment overheating.
4. Fabrication & Testing
Building the enclosure and performing post-installation dB testing to guarantee compliance.
Technical Specifications
Outer Cladding (Skin)
1.6mm to 2mm thick CRCA/Galvanized steel sheets, powder-coated for superior weather and UV resistance.
Acoustic Core Material
High-density Rockwool or Glasswool (typically 64 kg/m³ to 96 kg/m³ density) wrapped in fiberglass tissue.
Inner Cladding
Perforated GI or Aluminum sheets (approx. 35-40% open area) allowing sound waves to enter the acoustic core.
Hardware & Sealing
Heavy-duty, lockable stainless steel hinges and EPDM rubber gaskets on all doors to prevent sound leakage.
