Description

Technical Specifications:

• Model: AR-04AE-13574
• Series: AR — Modular Filter/Regulator
• Port Size: 1/4″ NPT (G 1/4″)
• Flow Capacity (Cv): 0.4 (at 6 bar inlet, 1 bar pressure drop)
• Max Inlet Pressure: 16 bar (232 psi)
• Regulated Output Pressure Range: 0.5–10 bar (7–145 psi), adjustable via knob
• Filtration Rating: 5 μm (standard), 1 μm or 40 μm available as variants
• Bowl Material: Polycarbonate (transparent, shatter-resistant)
• Bowl Capacity: 30 cm³
• Operating Temperature: -10°C to +60°C
• Max Ambient Temperature: +60°C
• Drain Type: Manual drain (with option for auto-drain)
• Connection Type: 1/4″ NPT female threads
• Weight: 0.12 kg
• Compliance: ISO 8573-1, CE, ATEX optional (for hazardous areas)

Functional Features:

• Two-stage filtration: cyclonic separator + sintered element
• Adjustable pressure regulation with gauge (on some variants)
• Transparent bowl for visual moisture inspection
• Modular design — stackable with other AR/AF/AL modules
• Low pressure drop design for energy efficiency

Structural Characteristics:

• Body: Die-cast zinc alloy with nickel plating
• Filter element: Sintered bronze or stainless steel
• Seal: NBR (Nitrile Butadiene Rubber)
• Knob: Polypropylene, color-coded per pressure range (white for 0.5–2 bar, etc.)

Working Principle: Compressed air enters the unit and passes through a cyclonic separator that removes bulk water and particulates by centrifugal force. The air then passes through a sintered metal filter element that captures particles down to 5 μm. The regulated section contains a poppet valve controlled by an adjustment spring. Turning the knob compresses or decompresses the spring, which sets the downstream pressure. The valve opens or closes to maintain the set pressure regardless of inlet pressure fluctuations (within the regulator’s range).

Advantages:

• Modular system allows custom configuration (filter + regulator + lubricator in one stack)
• Transparent bowl eliminates guesswork for maintenance
• Low pressure drop saves energy
• Proven reliability in millions of installations worldwide

Applicable Industries: General manufacturing, packaging machinery, food & beverage, pharmaceutical, automotive assembly, electronics

Installation Requirements:

• Mount in vertical orientation (bowl down) for proper drainage
• Upstream of any air-consuming device
• Minimum 5 diameters of straight pipe upstream, 3 diameters downstream
• Max ambient temperature 60°C — do not install near heat sources

Usage Precautions:

• Drain bowl regularly — at minimum daily in humid environments
• Replace filter element per maintenance schedule (typically every 6–12 months)
• Do not exceed max inlet pressure of 16 bar
• Use only Parker-approved replacement elements to maintain filtration rating
