ROCKER Rocker320 Oil-Free Laboratory Air Compressor

Overview

The ROCKER Rocker320 Oil-Free Laboratory Air Compressor is an engineered solution for clean, reliable, and low-maintenance compressed air supply in analytical, microbiological, and process-support laboratory environments. Utilizing a direct-drive piston compression mechanism—free of lubricating oil—the Rocker320 eliminates the risk of hydrocarbon contamination in downstream applications such as gas chromatography sample introduction, membrane filtration, aquarium aeration, and positive-pressure cabinet operation. Its compact footprint (27.2 × 13.6 × 16.5 cm), lightweight design (4.1 kg), and quiet operation (≤50.0 dB[A]) make it suitable for benchtop integration in ISO Class 5–7 cleanrooms, QC labs, and teaching facilities where spatial constraints and acoustic performance are critical. Designed to operate continuously under variable load conditions, the unit delivers stable airflow up to 12 L/min at regulated pressures up to 80 psi (5.5 bar) when equipped with the integrated coalescing filter assembly.

Key Features

• Oil-free piston compression architecture ensures zero oil carryover—critical for applications requiring ISO 8573-1 Class 0 certified air quality.
• Integrated thermal protection switch automatically interrupts motor power during overheating events and resumes operation upon safe cooldown—enhancing system longevity and operational safety.
• Standard stainless-steel reinforced outlet filter cartridge removes particulates, aerosols, and condensed moisture, delivering purified air compliant with general laboratory-grade specifications.
• Direct-coupled motor-to-piston transmission eliminates belt slippage, vibration harmonics, and associated maintenance—contributing to consistent pressure stability and extended service intervals.
• CE-marked and CSA-certified for electrical safety compliance in both EU and North American regulatory jurisdictions (EN 61000-6-3, EN 61000-6-1, CSA C22.2 No. 61010-1).
• Front-panel pressure regulator enables precise downstream pressure control without external accessories; calibrated scale supports repeatable setpoint reproducibility.

Sample Compatibility & Compliance

The Rocker320 is compatible with standard 8 mm (5/16″) ID laboratory tubing and connects seamlessly to common pneumatic interfaces used in vacuum manifolds, peristaltic pump drivers, and positive-pressure filtration systems. While not intended for medical gas or breathing-air applications, its output meets general-purpose requirements for non-critical instrumentation support per ISO 8573-7:2003 (solid particle and water content classification). The unit conforms to IEC 61000 electromagnetic compatibility standards and includes built-in surge suppression for stable performance in shared lab power circuits. Documentation packages include Declaration of Conformity (DoC) for CE and CSA certifications—supporting GLP audit readiness and equipment qualification protocols.

Software & Data Management

As a standalone mechanical compressor, the Rocker320 does not incorporate digital control interfaces, embedded firmware, or data logging capabilities. It operates via manual on/off actuation and analog pressure regulation—aligning with traditional laboratory infrastructure where simplicity, reliability, and minimal validation overhead are prioritized. For laboratories implementing 21 CFR Part 11-compliant workflows, the device qualifies as “non-configurable hardware” and requires only basic equipment identification, calibration verification (pressure gauge accuracy check), and preventive maintenance records—fully traceable through the included two-year parts warranty documentation.

Applications

• Positive-pressure air supply for sterile filtration housings and laminar flow hoods.
• Aeration of microbial culture media and aquatic life support systems.
• Actuation of pneumatic valves in automated liquid handling platforms.
• Gas supply for flame ionization detectors (FID), nitrogen generators, and zero-air scrubbers.
• Driving air-powered microcentrifuges and pipette washers in high-throughput settings.
• Supporting environmental monitoring systems requiring continuous low-flow compressed air.

FAQ

Is the Rocker320 suitable for use with gas chromatography instruments?
Yes—its oil-free design prevents column contamination and detector fouling; however, users should verify compatibility with instrument manufacturer specifications and consider adding a secondary desiccant or hydrocarbon trap for ultra-high-purity applications.
Does the unit include a pressure gauge?
Yes—a calibrated analog pressure gauge is mounted directly on the front panel adjacent to the regulator knob for real-time output monitoring.
What maintenance is required over the 2-year warranty period?
None beyond periodic visual inspection of the filter element and replacement every 6–12 months depending on ambient dust levels; no lubrication, belt tensioning, or internal servicing is necessary.
Can the Rocker320 be operated continuously for 24/7 applications?
It is rated for intermittent duty (duty cycle ≤ 70%); sustained continuous operation may reduce thermal margin and is not recommended without external cooling or duty-cycle monitoring.
Is the CE marking valid for use in UK laboratories post-Brexit?
The CE mark remains accepted for legacy equipment placed on the GB market prior to January 1, 2023; for new installations, UKCA marking is advised—ROCKER provides technical files supporting UKCA self-declaration upon request.
