The AR and BR Series represent the industry-standard “Airtac Type” pneumatic regulators, renowned for their compact footprint and stable pressure regulation. These units are essential components in any compressed air system, designed to reduce supply pressure to a specific, constant work pressure regardless of upstream fluctuations.
At Anruk Pneumatic, we manufacture high-performance AR and BR regulators that are 100% interchangeable with original Airtac specifications, providing a cost-effective solution for OEM and MRO applications.
Technical Comparison: AR vs. BR
| Technical Comparison: AR vs. BR | ||||
|---|---|---|---|---|
| Series | Body Size | Port Sizes (G/NPT/PT) | Flow Rate (L/min) | Application |
| AR2000 | Mini | 1/8″, 1/4″ | Up to 550 | Lab equipment, small actuators |
| BR2000 | Standard | 1/4″ | Up to 1100 | General automation |
| BR3000 | Medium | 3/8″ | Up to 2500 | Medium-bore cylinders |
| BR4000 | Large | 1/2″ | Up to 6000 | Heavy industrial machinery |
Key Features & Benefits
1. High-Precision Regulation
Equipped with a balanced valve structure, the AR/BR series provides excellent pressure stability. It effectively eliminates the “water hammer” effect of air surges, ensuring your downstream tools and valves operate at peak efficiency.
2. Robust Locking Mechanism
The adjustment knob features a “Push-to-Lock” safety design. Simply pull up to adjust the pressure and press down to lock the setting. This prevents accidental pressure shifts due to machine vibration or human error.
3. Modular Integration
These regulators are designed for easy assembly into F.R.L. units. Using T-brackets or joiners, they can be seamlessly connected to:
- AF/BF Series Filters (to create an AC/BC combo)
- AL/BL Series Lubricators (for full F.R.L. systems)
4. Pressure Gauge Options
Standard units include a high-visibility circular pressure gauge. We also offer square embedded gauges for a more compact, streamlined look on control panels.

Why Buy Airtac-Type Regulators from Anruk?
- Strict Interchangeability: Our AR/BR units match standard mounting holes and dimensions, allowing for drop-in replacement of existing Airtac units.
- Durable Seals: We use high-grade NBR seals to ensure long-term airtight performance and resistance to industrial lubricants.
- B2B Customization: We offer customized pressure ranges (e.g., low pressure 0.2 MPa or high pressure 1.0 MPa) and private labeling for distributors.
- Bulk Availability: Large inventory maintained for common sizes (AR2000, BR3000, BR4000) to ensure rapid global shipping.
Installation Guidelines
- Clean the Pipes: Ensure all piping is free of dust and sealing tape fragments before installation.
- Flow Direction: Follow the arrow on the body for the correct air flow direction (Inlet to Outlet).
- Vertical Mounting: For optimal performance and longevity of the internal diaphragm, mount the regulator vertically with the knob facing upwards.
