ROCKER Rocker800 Oil-Free Vacuum Pump

Overview

The ROCKER Rocker800 Oil-Free Vacuum Pump is an engineered solution for laboratories requiring reliable, contamination-free vacuum generation in routine and demanding applications. Based on a precision-machined reciprocating piston mechanism, this pump operates without lubricating oil—eliminating oil carryover, vapor backstreaming, and associated maintenance cycles. Its dry-running architecture ensures consistent performance across extended duty cycles while preserving sample integrity in sensitive processes such as solvent removal, lyophilization support, and vacuum-assisted filtration. Designed and manufactured in Taiwan under strict quality control protocols, the Rocker800 complies with IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity) standards, and carries full CE marking for safety and electromagnetic compatibility within the European Economic Area.

Key Features

• Oil-free piston design ensures zero hydrocarbon contamination—critical for analytical sample preparation, pharmaceutical QA/QC, and cleanroom-compatible workflows.
• Integrated thermal protection switch automatically interrupts motor operation when internal temperature exceeds safe thresholds; system resumes operation autonomously after cooling, minimizing downtime and extending service life.
• Robust cast-aluminum housing provides mechanical stability and efficient heat dissipation during continuous operation at rated load.
• Low-noise operation at 68.0 dB(A) enables integration into shared laboratory environments without acoustic interference to adjacent instrumentation or personnel.
• Universal hose interface accepts standard 3/8-inch (9.5 mm) ID vacuum tubing—compatible with common Buchner funnels, vacuum desiccators, drying ovens, and filtration manifolds.
• Energy-efficient 220 W motor delivers 80 L/min free-air flow at 670 mmHg ultimate vacuum—optimized for high-throughput vacuum drying and rapid degassing of viscous or particulate-laden solutions.

Sample Compatibility & Compliance

The Rocker800 is suitable for non-corrosive, non-condensable gas streams typical of aqueous and organic solvent evaporation, inert-gas purging, and vacuum-assisted solid–liquid separation. It is not intended for use with aggressive vapors (e.g., halogenated solvents, strong acids, or oxidizers) unless paired with appropriate cold traps or chemical scrubbers. The pump meets CE requirements per Directive 2014/35/EU (Low Voltage Directive) and 2014/30/EU (EMC Directive), supporting compliance with ISO/IEC 17025-accredited laboratory quality systems. While not intrinsically rated for hazardous locations, its oil-free construction reduces fire risk compared to oil-lubricated alternatives—making it appropriate for general-purpose labs operating under GLP or basic GMP-aligned procedures.

Software & Data Management

The Rocker800 is a standalone analog vacuum source with no embedded microcontroller, touchscreen interface, or digital communication ports (e.g., RS-232, USB, or Ethernet). As such, it does not generate electronic audit trails, data logs, or user-accessible firmware. This architecture aligns with laboratories prioritizing simplicity, long-term reliability, and minimal validation burden—particularly where vacuum generation is a supporting utility rather than a regulated critical process step. For environments requiring 21 CFR Part 11-compliant recordkeeping, integration with external pressure transducers and data acquisition systems (e.g., LabVIEW, SCADA, or ELN platforms) is recommended to capture real-time vacuum level and runtime metadata.

Applications

• Vacuum drying of heat-sensitive biological samples, polymers, and ceramics in benchtop or cabinet-style ovens.
• Rapid vacuum filtration of cell cultures, precipitates, or particulates using glass or polypropylene filter holders.
• Deaeration of adhesives, resins, coatings, and composite preforms prior to casting or lamination.
• Support vacuum manifold systems for parallel sample processing in environmental, food, and clinical testing labs.
• Evacuation of desiccators and glove boxes during moisture-sensitive material handling.
• Pre-vacuum conditioning of membrane filters and chromatography columns prior to solvent equilibration.

FAQ

Is the Rocker800 compatible with vacuum ovens requiring stable deep vacuum?
The Rocker800 achieves an ultimate vacuum of 670 mmHg (~90 kPa absolute), which is sufficient for most convection-style vacuum drying applications but not suitable for high-vacuum processes requiring <100 mbar or molecular-level evacuation.
Can it be used continuously for 8+ hours per day?
Yes—the thermal cut-off protection and optimized cooling geometry support sustained operation under nominal load; however, intermittent duty (e.g., 45 min on / 15 min off) is recommended for maximum longevity in high-ambient-temperature environments.
Does it require periodic filter replacement or maintenance?
No scheduled maintenance is required beyond visual inspection of intake filters (if installed externally) and verification of hose integrity; the absence of oil eliminates oil changes, vapor trap servicing, or valve reseating.
Is AC110V/60Hz version available for North American labs?
Yes—model variants with 110 V / 60 Hz input are available under separate part numbers and retain identical performance specifications, including flow rate and ultimate vacuum.
How does it compare to diaphragm-based oil-free pumps?
Unlike diaphragm pumps, the Rocker800’s piston mechanism delivers higher volumetric efficiency and greater tolerance to transient particulate ingress, making it more robust for filtration-heavy workflows—but with slightly higher acoustic output and mechanical vibration.
