Overview
The SETA 22422 is a compact, oil-lubricated rotary vane vacuum pump engineered for precision laboratory applications requiring stable, high-vacuum performance in space-constrained environments. Based on proven positive-displacement rotary vane technology, it achieves an ultimate vacuum of 1×10⁻² mbar—sufficient for degassing solvents, vacuum filtration, rotary evaporation support, and low-pressure drying protocols. Its dual-speed motor delivers selectable free-air displacement rates of 46 L/min (low-noise mode) and 66 L/min (high-throughput mode), enabling flexible integration across diverse workflows without sacrificing thermal or mechanical stability. Designed and manufactured in Italy, the unit complies with IEC 61000-6-3 (EMC emission standards) and meets CE marking requirements for laboratory equipment within the European Economic Area.
Key Features
- Ultra-compact footprint (270 × 150 × 250 mm) optimized for benchtop use in analytical labs, QC facilities, and university teaching laboratories.
- Dual-speed motor control allows users to balance vacuum speed, noise level (<58 dB(A) at 1 m), and operational longevity based on process requirements.
- Integrated oil mist filter captures >99.5% of entrained lubricant aerosols, minimizing oil vapor backstreaming and protecting downstream instrumentation—including mass spectrometers, vacuum gauges, and sample chambers.
- Robust cast-aluminum housing with vibration-damped mounting feet ensures mechanical stability during continuous operation and reduces transmission of harmonic resonance to sensitive adjacent equipment.
- Oil-level sight glass and accessible drain plug facilitate routine maintenance in accordance with ISO 8573-1 Class 4 compressed air purity guidelines for lubricated systems.
Sample Compatibility & Compliance
The SETA 22422 is compatible with standard laboratory vacuum lines using 1/4″ NPT-F inlet connections and supports common vacuum-rated tubing (e.g., reinforced PVC, Viton®, and silicone). It is not intended for handling corrosive, condensable, or particulate-laden gases without external trapping or scrubbing. The pump conforms to EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions), and its oil-lubricated architecture meets the material compatibility expectations outlined in ASTM D2622 for hydrocarbon-based vacuum oils. While not certified for cleanroom Class 5 (ISO 14644-1) operation, its filtered exhaust output aligns with general laboratory indoor air quality (IAQ) recommendations per ASHRAE Standard 62.1.
Software & Data Management
This is a standalone analog-operated vacuum pump with no embedded microcontroller, digital interface, or software dependency. All operational parameters—including speed selection, on/off state, and visual oil-level monitoring—are managed manually via front-panel toggle switches and direct observation. As such, it requires no firmware updates, network configuration, or cybersecurity validation. Its design inherently satisfies audit-trail simplicity for GLP-compliant environments where electronic logging is not mandated; usage records may be maintained manually in lab notebooks or integrated into broader LIMS workflows via external vacuum pressure loggers (e.g., connected Pirani or capacitance manometers).
Applications
- Supporting rotary evaporators in organic synthesis and natural product isolation labs.
- Enabling vacuum-assisted filtration for particulate analysis (e.g., EPA Method 160.1) and membrane integrity testing.
- Providing primary vacuum for small-scale freeze dryers used in pharmaceutical formulation development.
- Serving as a backing pump for turbomolecular or diffusion pumps in surface science and thin-film deposition setups.
- Facilitating vacuum desiccation of hygroscopic reference standards prior to gravimetric analysis (USP <1251>).
FAQ
Is the SETA 22422 suitable for continuous 24/7 operation?
Yes—when operated within ambient temperatures of 15–30°C and relative humidity ≤70%, with scheduled oil changes every 500 hours or per manufacturer’s maintenance schedule.
What type of vacuum oil is recommended?
SETA specifies ISO VG 100 mineral-based vacuum oil (e.g., SETA VAC-OIL 100 or equivalent meeting DIN 51506 VDL specifications); synthetic alternatives must be verified for compatibility with nitrile elastomer seals.
Can this pump be used with aggressive solvents like acetone or chloroform?
No—direct exposure to condensable vapors will contaminate the oil and impair pumping efficiency; a cold trap or chemical scrubber is required upstream.
Does the unit include a vacuum gauge?
No—the pump does not integrate a built-in pressure sensor; external vacuum measurement must be performed using a calibrated gauge installed in the vacuum line.
Is the oil mist filter replaceable, and how often should it be serviced?
Yes—the filter element is field-replaceable (SETA part #FIL-22422); inspection is recommended every 200 operating hours, with replacement typically required every 1,000 hours under normal lab conditions.
