Overview
The Agilent RP-4001 Roots vacuum pump is a high-performance, dry, positive-displacement vacuum booster designed for integration into multi-stage vacuum systems where rapid evacuation of large gas volumes at low to medium vacuum ranges (typically 1–100 mbar) is required. Operating on the principle of synchronized, non-contacting rotary lobes—two figure-eight-shaped rotors rotating in precise phase opposition—the RP-4001 generates continuous volumetric displacement without internal lubrication in the pumping chamber. This dry-running architecture eliminates oil backstreaming, hydrocarbon contamination, and maintenance associated with lubricated vacuum stages, making it ideal for ultra-clean applications such as semiconductor process chambers, analytical instrumentation (e.g., mass spectrometry vacuum manifolds), and high-purity coating systems. As a booster pump, the RP-4001 is engineered to operate downstream of a primary roughing pump (e.g., scroll or diaphragm pump), extending the effective operating range by improving the ultimate base pressure of the forepump by approximately one order of magnitude.
Key Features
- Dry, oil-free operation: Non-contacting lobe design ensures zero lubricant ingress into the vacuum path, supporting ISO Class 5 (Class 100) cleanroom-compatible processes.
- Industry-leading maximum allowable pressure differential: Rated up to 75 mbar (abs), enabling robust start-up performance even under high inlet pressure conditions—critical for batch-process load-lock evacuation and fast pump-down cycles.
- Dynamic rotor balancing and precision timing gears: Minimize mechanical vibration and acoustic emission (<65 dB(A) at 1 m), supporting installation in noise-sensitive laboratory and R&D environments.
- Integrated high-capacity condensate trap and fluoropolymer-sealed bearing housings: Prevents particulate shedding and vapor-phase contaminant carryover, enhancing long-term reliability in solvent-rich or reactive gas applications.
- Compact, modular footprint with front-access service points: Designed for space-constrained integration into OEM vacuum subsystems or benchtop analytical platforms.
- Optional variable-frequency drive (VFD): Enables stable rotational speed control independent of local mains frequency (50/60 Hz); delivers up to 20% higher volumetric flow rate at 50 Hz compared to fixed-speed equivalents, ensuring consistent performance across global installations.
Sample Compatibility & Compliance
The RP-4001 is compatible with inert, mildly corrosive, and condensable gas streams typical in physical vapor deposition (PVD), electron microscopy sample preparation, residual gas analysis (RGA), and vacuum drying. It is not intended for use with strongly oxidizing agents (e.g., ClF₃, F₂), halogenated solvents above dew point, or abrasive particulates without upstream filtration. The pump complies with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity). Its construction adheres to ASME BPE surface finish specifications (Ra ≤ 0.8 µm) for sanitary vacuum interfaces. While not intrinsically rated for hazardous locations, optional ATEX-compliant motor variants are available upon request for Zone 2 classified areas.
Software & Data Management
The RP-4001 supports analog (0–10 V / 4–20 mA) and digital (RS-485 Modbus RTU) interface protocols for integration into centralized vacuum system controllers. When paired with Agilent’s VacuGraph™ monitoring software (sold separately), users gain real-time access to rotational speed, motor current, thermal status, and runtime diagnostics. Audit trails, event logging, and configurable alarm thresholds support GLP/GMP-aligned documentation requirements. Firmware updates are performed via secure USB interface, and all operational parameters are stored in non-volatile memory to ensure traceability during FDA 21 CFR Part 11-compliant validation protocols.
Applications
- Rapid evacuation of load locks and transfer chambers in thin-film deposition tools
- Backing high-vacuum turbomolecular pumps in surface science UHV systems
- Vacuum degassing of polymer melts and composite resins prior to curing
- Supporting vacuum ovens and freeze dryers requiring high throughput at 10–50 mbar
- Gas handling in helium leak detection systems where hydrocarbon-free vacuum integrity is mandatory
- Process vacuum for analytical instruments including X-ray photoelectron spectroscopy (XPS) and secondary ion mass spectrometry (SIMS)
FAQ
Can the RP-4001 operate as a standalone vacuum pump?
No—it requires a backing pump capable of reaching ≤10 mbar to establish initial vacuum; it functions exclusively as a booster stage.
What is the recommended foreline pressure limit for continuous operation?
Maximum allowable pressure differential is 75 mbar; sustained operation above this threshold may trigger thermal overload protection.
Is the RP-4001 suitable for pumping solvent vapors?
Yes, when equipped with the optional high-capacity cold trap and operated within its specified condensable load limits (up to 5 g/h water-equivalent at 20°C).
Does the pump require periodic oil changes?
No—rotor chamber is entirely dry; only the external gearmotor housing requires scheduled grease replenishment per 10,000 hours of operation.
Can the VFD option be retrofitted to existing RP-4001 units?
Yes, provided the motor winding configuration and controller interface match Agilent’s RP-VFD upgrade kit (part number RP-VFD-KIT-01).
