Proven Heavy-Duty Design. Advanced Engineering. Unmatched Reliability.

The BL Series piston compressors combine rugged, heavy-duty construction with modern engineering innovations to deliver one thing above all - uncompromising reliability in every application.
From small workshops to demanding industrial environments, these compressors are purpose-built to keep your operations running efficiently, day after day.

 

Durable Heavy-Duty NEMA Motors

Built for performance and longevity, the BL Series utilizes industrial-grade NEMA electric motors that provide consistent power and reliability even under continuous operation.
Available in Single-Phase and Three-Phase configurations, they offer full flexibility to suit any workspace or electrical infrastructure.

Independent Magnetic Motor Starter with Integrated Relay

• Ensures safe and reliable motor activation.
• Includes under-voltage and overload protection for enhanced equipment safety and extended service life.

Heavy-Duty Two-Stage Solid Cast-Iron Pumps

Each pump is designed for maximum durability and efficiency, featuring:

• Industrial-grade removable disc valves for easy maintenance.
• Dual solid-steel connecting rods for strength and stability.
• Low operating RPM for reduced wear and longer lifespan.

Integrated Intercooler and Aftercooler System

• The intercooler reduces air temperature between stages to increase compression efficiency.
• The aftercooler cools compressed air before storage, improving moisture removal and overall system performance.

60/80/120-Gallon ASME-Certified Air Receiver

• ASME-approved tanks ensure full compliance and safety.
• Vibration-isolation pads minimize noise and structural stress.
• Includes an automatic 110 V dual-timer tank drain, virtually eliminating the need for manual drainage.

 Fully Enclosed Heavy-Duty Steel Belt Guard

• Protects the operator by preventing accidental contact with moving parts.
• Integrated belt tensioner reduces vibration and extends belt service life.

Engineered for Performance - Built for Industry

The BL Series by EL-AV is the professional choice for those who demand endurance, efficiency, and reliability from their air systems.
Every component is designed for years of trouble-free service — a compressor that works as hard as you do.

  1. 100% Heavy-Duty Durability
    Constructed with a full cast-iron pump and crankcase, the BL Series is engineered for maximum strength and superior wear resistance. Oversized bearings and precision-balanced crankshafts minimize vibration and significantly extend operational life — even with continuous duty in the most demanding work environments.

  2. Maximum Efficiency & Lower Energy Costs
    Optimized cylinder geometry and slow-running design deliver higher CFM per horsepower. A robust cooling system — featuring oversized after-coolers — ensures lower discharge temperatures and enhanced performance, while premium-efficiency induction motors with built-in thermal protection help reduce power consumption and increase reliability.

  3. Easy & Cost-Effective Maintenance
    The BL Series simplifies servicing with individually cast cylinders and accessible valve pockets. Long-life stainless-steel valves, high-quality piston rings, and an automatic 110 V dual-timer tank drain make moisture removal and routine upkeep fast, simple and low-cost — minimizing downtime and service labour.

  4. Extended Equipment Life
    Large intercoolers and after-coolers provide optimal heat dissipation, protecting pistons, valves and other components from excessive thermal stress. Integrated safety features — including low-oil protection and robust motor starters — safeguard equipment, prevent unplanned shutdowns and ensure long operational cycles.

  5. Flexible Configurations & Adaptability
    Whether you need a compact setup or a powerful production line solution, the BL Series offers adaptable formats: two-stage pump units, vertical or horizontal tank configurations, duplex systems, and a wide range of compatible accessories — including dryers, filters, drains and smart control modules. This versatility allows you to tailor the system to your exact air-quality and productivity requirements.

The BL Series two-stage piston compressors by EL-AV Compressors are purpose-built for demanding industrial environments that require constant, dependable air supply. Designed with cast-iron cylinders, industrial-grade motors, and a high-efficiency aluminum intercooler and after-cooler system, these compressors ensure lower discharge temperatures, reduced moisture, and superior air quality.

Every BL Series unit is manufactured for continuous operation, offering exceptional performance and durability with minimal maintenance. The compressors feature precision-balanced components for smooth operation, an auto-drain system for easy water removal, and heavy-duty belt guards that enhance both safety and cooling efficiency.

All parts and assemblies are UL-certified, and the air receivers are ASME-approved, guaranteeing full compliance with international safety standards. This makes the BL Series ideal for factories, automotive workshops, laboratories, and any application that demands long-term reliability and clean compressed air.

When efficiency, endurance, and consistent performance matter most, the BL Series by EL-AV stands as the professional choice — engineered for performance, built for industry.
