Proven Heavy-Duty Design. Advanced Engineering. Unmatched Reliability.
The BL Series two-stage reciprocating piston compressors combine rugged, heavy-duty construction with modern engineering innovations to deliver one thing above all: uncompromising reliability in every industrial application. From small commercial workshops to demanding industrial manufacturing environments, these compressors are purpose-built to keep your operations running efficiently, day after day.
Durable Heavy-Duty NEMA Motors
Built for maximum performance and longevity, the BL Series utilizes industrial-grade NEMA electric motors that provide consistent power and operational reliability, even under continuous heavy-duty cycles. Available in single-phase and three-phase configurations, they offer full flexibility to match your facility's electrical infrastructure.
Independent Magnetic Motor Starter with Integrated Relay
- Ensures safe, smooth, and reliable motor activation under heavy load.
- Includes under-voltage and thermal overload protection to safeguard equipment and extend overall service life.
Heavy-Duty Two-Stage Solid Cast-Iron Pumps
Each pump is engineered for maximum durability, thermal stability, and efficiency, featuring:
- Industrial-grade removable disc valves for simplified maintenance and serviceability.
- Dual solid-steel connecting rods for superior structural integrity and load distribution.
- Low operating RPM to minimize component wear, reduce heat generation, and extend operational lifespan.
Integrated Intercooler and Aftercooler System
- Intercooler: Reduces air temperature between compression stages to maximize volumetric efficiency.
- Aftercooler: Cools compressed discharge air prior to receiver storage, significantly enhancing moisture removal and overall air quality.
60 / 80 / 120-Gallon ASME-Certified Air Receiver
- ASME-Approved Tanks: Fully certified to meet strict safety and compliance standards.
- Vibration-Isolation Pads: Minimize structural vibration, reduce ambient operational noise, and prevent mechanical stress.
- Automatic 110V Dual-Timer Tank Drain: Automatically evacuates condensate to eliminate manual maintenance routines.
Fully Enclosed Heavy-Duty Steel Belt Guard
- Protects operators by completely enclosing moving drive components in compliance with safety standards.
- Integrated belt tensioner system reduces vibration and extends drive belt longevity.
Key Advantages
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 operational vibration and significantly extend compressor lifespan — even during continuous, heavy-duty duty cycles in demanding work environments.
2. Maximum Efficiency & Lower Energy Costs
Optimized cylinder geometry and a low-RPM running design deliver higher air output (CFM) per horsepower. A robust cooling architecture — featuring oversized aftercoolers — ensures lower discharge air temperatures, while premium-efficiency induction motors with built-in thermal overload protection help reduce power consumption and operational costs.
3. Easy & Cost-Effective Maintenance
The BL Series simplifies routine servicing with individually cast cylinders and easily accessible valve pockets. High-durability stainless-steel valves, premium piston rings, and an automated 110V dual-timer tank drain make moisture management and scheduled upkeep fast and cost-effective — minimizing facility downtime and labor costs.
4. Extended Equipment Lifespan
Large intercoolers and aftercoolers ensure optimal heat dissipation, protecting internal pistons, valves, and mechanical components from thermal stress. Integrated safety features — including automatic low-oil shutdown protection and heavy-duty motor starters — protect your investment and prevent unplanned operational disruptions.
5. Flexible Configurations & High Adaptability
Whether you require a compact workspace setup or a high-capacity industrial production solution, the BL Series provides adaptable formats: two-stage pump configurations, vertical or horizontal ASME air tanks, duplex systems, and a complete suite of compressed air treatment accessories (including air dryers, inline filters, and smart control modules) tailored to your exact air-quality requirements.
Engineered for Performance — Built for Industry
The BL Series by EL-AV Compressors is the professional choice for facility managers and engineers who demand endurance, energy efficiency, and total reliability from their compressed air systems. Every component is engineered for years of trouble-free, continuous operation — delivering a compressor that works as hard as your business does.
