BelAire QP338VLE Air Compressor – 30HP Quiet

BelAire QP338VLE 7.5HP 80-Gallon Vertical Quiet Performance Duplex Air Compressor

The BelAire QP338VLE stands at the forefront of industrial noise-reduction technology, specifically designed for professional shops where workspace silence and air reliability are equally critical. This 7.5HP duplex system features two high-efficiency pumps housed within an integrated sound-dampening enclosure, effectively reducing operational noise by up to 80% compared to standard open-frame compressors. Mounted on a space-saving 80-gallon vertical tank, this unit delivers a consistent 25.3 CFM at 100 PSI while maintaining an incredibly small floor footprint.

As part of the Elite Quiet Performance (QP) series, the QP338VLE is engineered for zero-downtime environments. The duplex architecture utilizes two 5HP pumps that alternate operation through a lead/lag control system. This not only ensures equal wear across both motors but also provides built-in redundancy; if one pump requires maintenance, your facility remains operational. The “Elite” feature set enhances this reliability further with an automatic tank drain and a low oil level shutdown, automating critical maintenance tasks to protect your investment.

BelAire QP338VLE Technical Performance Breakdown

• Horsepower: 7.5 HP Duplex system with dual high-efficiency motors.
• Air Delivery: 25.3 CFM at 100 PSI / 22.3 CFM at 175 PSI.
• Noise Reduction: QP Series acoustic enclosure for ultra-quiet operation.
• Tank Configuration: 80-Gallon Vertical ASME tank for maximum space efficiency.
• Elite Features: Pre-installed Auto Tank Drain and Low Oil Shutdown switch.

To be honest, our technical crew views the QP338VLE as the ultimate “silent partner” for precision manufacturing. Most shop owners are surprised that a duplex system can fit into such a tight vertical space while staying quiet enough for a normal conversation. If you are evaluating different horsepower levels or tank sizes for your shop, explore our full range of industrial air compressors to find the ideal balance between tank capacity and motor horsepower for your facility.

Engineered for High-Pressure Precision

The QP338VLE operates at lower RPMs to minimize friction and heat, which is essential for preserving the integrity of the internal valves and bearings. The two-stage pumps are constructed from 100% solid cast iron, ensuring they can handle the rigors of a continuous duty cycle without overheating. Building a more efficient workspace starts with the premium selections found in our MulDepot professional equipment catalog, where we prioritize machines that solve both air volume and environmental noise challenges.

• Automatic Tank Drain: Routinely clears condensate to maintain high air quality and prevent tank rust.
• Low Oil Level Shutdown: A fail-safe mechanism that prevents catastrophic pump seizure.
• Balanced Flywheels: Ensures smooth operation with minimal structural vibration.
• Concentric Ring Valves: Optimized for high-flow volumetric efficiency and durability.

Ideal Applications for Quiet High-Volume Air

• High-end automotive restoration shops where silence improves communication.
• Precision CNC machine shops needing a compact and quiet 7.5HP air source.
• Medical or laboratory environments requiring 100% uptime through duplex redundancy.
• Boutique fabrication studios located in noise-sensitive industrial parks.

The BelAire QP338VLE is a strategic solution for facilities that refuse to compromise between power and peace.
