Air Compressor Soundproof Enclosure
空压机隔音罩 中文页
The air compressor soundproof enclosure is a custom-engineered, full-unit acoustic shield for screw-type air compressors. The modular steel enclosure fully surrounds the compressor host, motor, and air tank connections. The outer panel is electrostatically powder-coated galvanized steel, with an inner perforated metal facing backed by an 80 mm centrifugal glass wool sound-absorbing layer (density 48 kg/m³, NRC≥0.85). Ventilation sound traps (acoustic louvers) are installed on the air inlet and exhaust sides to ensure cooling airflow is not compromised. Service doors with observation windows allow routine inspections without shutdown. The enclosure is custom-built to match the compressor's power rating and overall dimensions. On-site measured noise reduction at the same reference point before and after installation ranges from 15 to 25 dB(A), benefiting both the operator booth inside the room and sensitive receptor points at the facility boundary. Quotations are project-specific; please provide equipment dimensions or nameplate data for a detailed price list.

About This Product
Why Air Compressors Require Soundproof Enclosures
Screw air compressors are among the rare "24/7 continuous" noise sources in factories: rotor meshing noise, motor electromagnetic noise, and cooling fan wind noise combine to produce sound levels of 85–100 dB(A) at just 1 meter from the unit. Opening the machine room door sends noise directly into the workshop; for rooms located along exterior walls, site boundary measurements often exceed regulatory limits. An enclosure solves this by fully surrounding the noise source — blocking direct sound with the outer shell, absorbing reverberant sound inside the cavity, and using ventilated silencing louvers that allow cooling air to enter while preventing noise from escaping. All three functions are delivered in one integrated housing.
Enclosure Structure: Modular Assembly for On-Site Installation
The enclosure is constructed from standard pre-fabricated modules: the outer panel is 2.0 mm galvanized steel with electrostatic powder coating, the inner perforated metal facing is filled with 80 mm glass fiber insulation (density 48 kg/m³, NRC ≥ 0.85), and panels are bolted together with sealed gaskets at all joints. The modular design delivers three practical advantages: (1) large panels can be disassembled and carried through existing doors and windows — no wall demolition required for retrofit projects in older machine rooms; (2) individual modules can be replaced if access doors need to be added later; (3) the enclosure can be extended to accommodate future capacity expansion of the unit.
Ventilation & Cooling: Noise Reduction Without Compromising Heat Dissipation
Air compressors demand high airflow for cooling, and the most common reason enclosure installations fail is overheating. We separate the intake and exhaust faces, each fitted with acoustic louvers sized according to the unit's cooling air volume and the allowable temperature rise inside the enclosure. Exhaust air can be routed via ductwork to a designated discharge point outside the enclosure. All cable and pneumatic line penetrations are fitted with silencing sleeves and sealed to prevent sound leaks through gaps.
Maintenance & Observation: Daily Inspections Without Removing the Enclosure
The enclosure is provided with at least one maintenance door, single or double-leaf depending on site space, featuring a tempered glass observation window so operators can check oil levels and read control panel data without opening the door. Double-sealed gaskets ensure no sound leakage when the door is closed. For units requiring major service, removable roof panels can be pre-installed at the top of the enclosure, allowing partial access without compromising the overall structure.
Vibration Isolation & Piping: Eliminating Structure-Borne Noise
Compressor vibrations travel through the floor and connected piping, creating structure-borne noise that the enclosure alone cannot block. Rubber vibration isolators are placed between the enclosure base frame and the floor; flexible connectors are installed on both the inlet and outlet piping; and silencing sleeves at wall penetrations serve a dual purpose as vibration isolation seals. These measures, together with the enclosure itself, determine the final noise reduction performance — all items are confirmed during the proposal stage.
Quotation & Delivery
Pricing is calculated based on the total enclosure surface area, ranging from 600 to 1,500 RMB/m², including acoustic louvers and maintenance doors. Please provide the air compressor model, overall dimensions, and machine room layout (a hand-drawn sketch with measurements is sufficient), and we will return a complete technical proposal and itemized quotation the same day. Standard sizes are manufactured within 7–15 days. We can arrange on-site installation guidance, or your maintenance team can install according to the provided drawings. Every shipment includes material certificates and factory test reports, and each piece is photographed before loading for quality records.
Air Compressor Soundproof Enclosure — Frequently Asked Questions
The questions buyers ask most often about this product before placing an order.
How does this relate to our existing air compressor noise control services?
The soundproof enclosure is the core hardware within our broader mitigation solutions. If the compressor room also has issues such as insufficient wall隔音 or noise leakage through pipework, we can integrate the enclosure into a comprehensive noise control strategy—starting with source and path measurement, then determining whether a standalone enclosure or a combined approach delivers the best result.
