EL-AV introduced the BL Series two-stage, reciprocating air compressors. With a cast-iron pump, UL-certified components, integrated after-cooling and ASME-approved tanks, the BL Series is built for industry professionals who demand efficiency, endurance and clean compressed air without compromise.
When it comes to compressed air, reliability is everything. From factory floors to auto shops, every operation depends on air power that works as hard as its people. That’s where the new BL Series two-stage, reciprocating air compressors from EL-AV take the spotlight – combining classic heavy-duty design with advanced cooling technology for performance that simply doesn’t quit.
Every detail in the BL Series is designed to last. At its core is a two-stage solid cast-iron pump, the heart of an air compressor built for industrial duty. This heavy-duty construction ensures superior strength, minimal vibration and exceptional heat resistance. Unlike lighter single-stage models, the BL Series operates at low RPM, reducing wear and extending component life.
Inside the pump, dual solid-steel connecting rods and industrial-grade removable disc valves make maintenance straightforward while ensuring consistent performance under continuous load. Oversized bearings, precision-balanced crankshafts and stainless-steel valves all contribute to smooth operation and long service intervals.
Industrial reliability starts with compliance. Every BL Series air compressor is assembled from UL-certified components and mounted on an ASME-certified air receiver. Available in 60, 80 or 120-gallon configurations, each tank is equipped with vibration-isolation pads that minimize noise and structural stress. The system also features an automatic dual-timer tank drain, removing accumulated water automatically and reducing maintenance needs.
Traditional reciprocating air compressors are notorious for producing high discharge temperatures, which make it difficult to remove moisture from the air stream. Hot air carries more water vapor, leading to condensation downstream and the need for costly high-temperature dryers. The BL Series changes that equation. Each unit integrates an advanced aluminum intercooler and after-cooler system, along with an auto-drainer, which together reduce the air temperature dramatically before it leaves the compressor. This built-in cooling system improves air quality by reducing moisture content at the source and often eliminates the need for a high-temperature dryer and, in some installations, no dryer is needed at all.
Energy efficiency is built into every part of the BL Series. Optimized cylinder geometry and precision engineering deliver more cfm per horsepower, translating to higher air output with lower energy consumption. A premium-efficiency NEMA motor – available in single-phase or three-phase versions – provides reliable power and consistent performance under continuous duty. The system’s independent magnetic motor starter includes under-voltage and overload protection, preventing damage and extending motor life. All these features work together to minimize operating costs and ensure stable, uninterrupted production.
Downtime costs money, so the BL Series is designed for effortless upkeep. Individual cast cylinders and accessible valve pockets simplify service tasks, while long-life piston rings and high-grade materials reduce replacement frequency. The automatic 110-volt dual-timer drain eliminates the hassle of manual tank drainage, while fully enclosed heavy-duty belt guards protect operators and help cool the drive system.
The BL Series offers flexible configurations including vertical or horizontal tank layouts for space optimization and duplex systems for redundancy or alternating load sharing. It has compatibility with dryers, filters, drains and smart control modules, letting you tailor the system precisely to your workflow.
