The AL and BL Series Lubricators are the essential third component in professional air preparation systems. By injecting a controlled “oil mist” into the compressed air stream, these units ensure that pneumatic cylinders, valves, and air tools stay lubricated, reducing heat buildup, preventing seal wear, and stopping internal corrosion.
As a specialized B2B manufacturer, Anruk Pneumatic provides high-quality AL and BL Lubricators that offer seamless compatibility with international Airtac standards, delivering performance and durability for automated production lines.
Series Overview: AL vs. BL
The distinction between the AL and BL series allows for precise matching to system flow requirements:
- AL Series (Compact/Mini): Primarily the AL2000 (1/8″ and 1/4″ ports). Ideal for small-scale automation, laboratory equipment, and localized lubrication for a single valve bank.
- BL Series (Standard/High-Flow): Includes the BL2000, BL3000, and BL4000 (1/4″ to 1/2″ ports). Designed for larger industrial machinery, heavy-duty air tools, and systems requiring high CFM without significant pressure drop.
Technical Advantages of the AL/BL Lubricator
1. Proportional Oil Delivery
The AL and BL series use a drip-feed mechanism that is proportional to the air flow rate. Once the oil drip rate is set via the adjustment needle, the unit automatically maintains the correct oil-to-air ratio even if the system speed fluctuates.
2. High-Strength Reservoir Design
- Polycarbonate Bowls: Crystal-clear 360° visibility for oil level monitoring.
- Metal Protective Guards: Standard on the BL series (and optional for AL) to protect the bowl from chemical cracking or physical impact in harsh factory environments.
3. Ease of Maintenance
- Oil Refilling: These units are designed for easy refilling. The oil can be replenished without removing the unit from the air line, minimizing machine downtime.
- Adjustable Drip Rate: The transparent dome allows operators to visually verify the oil drip speed, ensuring the system is neither over-lubricated (wasting oil) nor under-lubricated (causing wear).
Installation & Usage Best Practices
To maximize the life of your pneumatic components, follow these guidelines when installing the AL/BL series:
- Placement: Always install the lubricator after the filter and regulator (the “L” in F.R.L.).
- Distance: Install the lubricator as close as possible to the component requiring lubrication (ideally within 5-8 meters) to prevent the oil mist from settling in the piping.
- Oil Type: Use only ISO VG32 or equivalent turbine oil (Class 1) to ensure proper atomization and to protect the internal seals of your pneumatic components.
Strategic Value for Distributors and OEMs
- Direct Interchangeability: Our AL/BL units match the dimensions and mounting patterns of the industry-standard Airtac series, making them an ideal choice for global MRO markets.
- Modular Assembly: Both series are designed to be joined with AFR/BFR units or separate AF/BF filters using standard T-brackets or joiner kits.
- Global Compliance: Available in G, NPT, and PT threads to meet the technical requirements of any regional market.
