ROCKER Rocker910 Oil-Free Vacuum Pump

Overview

The ROCKER Rocker910 Oil-Free Vacuum Pump is an engineered solution for laboratories requiring clean, reliable, and maintenance-free vacuum generation. Based on a precision-machined reciprocating piston mechanism, this pump operates without lubricating oil—eliminating the risk of oil backstreaming, vapor contamination, or hydrocarbon residue in sensitive applications such as solvent evaporation, vacuum filtration, or inert-atmosphere sample preparation. Its ultimate vacuum of 25 mbar (abs) and stable flow rate of 45 L/min support consistent performance across moderate-vacuum processes. Designed and manufactured in Taiwan under strict quality control, the Rocker910 complies with international safety and environmental directives—including CE, UKCA, and RoHS—ensuring suitability for regulated environments including GLP-compliant labs and ISO 17025-accredited testing facilities.

Key Features

• Oil-free piston technology ensures zero hydrocarbon emission and eliminates routine oil changes, filter replacements, or oil mist traps—reducing total cost of ownership and downtime.
• Integrated vacuum regulating valve enables precise, manual adjustment of operating vacuum level between atmospheric pressure and 25 mbar, facilitating process optimization for applications like controlled-rate drying or gentle degassing.
• Standard inlet filter cartridge (8 mm ID compatibility) captures particulates and ambient moisture prior to entry into the compression chamber, extending service life of the piston seal and cylinder bore.
• Thermal overload protection built into the motor windings automatically interrupts power when internal temperature exceeds safe operational limits; the system resumes operation after passive cooling—no manual reset required.
• Compact footprint (35 × 13 × 21 cm) and lightweight design (7 kg) allow flexible placement on benchtops, inside fume hoods, or integrated into modular vacuum manifolds.
• Low-noise operation at 68 dB(A) meets standard laboratory acoustic requirements, minimizing auditory fatigue during extended use.

Sample Compatibility & Compliance

The Rocker910 is compatible with aqueous, mildly corrosive, and non-condensable gas streams typical in analytical and preparative workflows—including vacuum-assisted filtration of biological suspensions, desiccation of hygroscopic compounds, and vacuum impregnation of porous media. It is not intended for continuous duty with highly condensable vapors (e.g., acetone, chloroform) or aggressive gases (e.g., HCl, Cl₂) without additional cold traps or chemical scrubbers. All electrical and mechanical components conform to EN 61000-6-3 (EMC), EN 61000-6-1 (immunity), and EN 60335-1 (safety). The CE and UKCA markings attest to conformity with the EU/UK Machinery Directive and Low Voltage Directive. RoHS compliance confirms restriction of hazardous substances per Annex II of Directive 2011/65/EU.

Software & Data Management

As a standalone analog vacuum source, the Rocker910 does not incorporate digital control interfaces, embedded firmware, or data logging capabilities. Its operation is fully manual via front-panel power switch and integrated vacuum regulator. However, it is compatible with external vacuum monitoring systems—including analog pressure transducers (0–10 V or 4–20 mA output) and programmable logic controllers (PLCs)—for integration into automated lab workflows. When deployed in FDA-regulated environments (e.g., pharmaceutical QC labs), users may document operational parameters (e.g., runtime, observed vacuum level, ambient temperature) manually or via connected validated instruments to satisfy 21 CFR Part 11 record-keeping expectations for equipment usage logs.

Applications

• Laboratory vacuum filtration of microbiological samples, cell cultures, and suspended solids (e.g., APHA Standard Method 2540D for TSS analysis).
• Vacuum drying and dehydration of heat-sensitive biomolecules, polymers, or pharmaceutical intermediates in vacuum ovens or desiccators.
• Deaeration and degassing of resins, adhesives, and casting compounds prior to curing—critical in materials science and electronics encapsulation.
• Air sampling for particulate matter (PM₁₀, PM₂.₅) collection using calibrated flow controllers and membrane filters.
• Supporting rotary evaporation systems where low-to-moderate vacuum suffices and oil-free integrity is mandatory (e.g., final solvent removal from natural product extracts).

FAQ

Is the Rocker910 suitable for continuous 24/7 operation?
No—it is rated for intermittent duty (duty cycle ≤ 60%); prolonged continuous use may accelerate wear of the piston seal and trigger thermal shutdown.
Can I connect it directly to a rotary evaporator?
Yes, provided the evaporator’s vacuum requirement falls within 25–100 mbar and no significant solvent vapors are expected to condense in the pump head; a cold trap is strongly recommended.
What maintenance is required?
Only periodic inspection and replacement of the inlet filter cartridge (recommended every 3–6 months depending on ambient dust load); no oil changes, valve adjustments, or seal servicing are needed under normal use.
Does it support vacuum monitoring via analog signal output?
No—the pump has no built-in pressure sensor or electronic interface; external gauges must be installed in the vacuum line.
Is a 110 V / 60 Hz version available?
Yes—model variant 167910-11 is supplied with 110 V, 60 Hz motor configuration upon request; ensure proper grounding and circuit protection per local electrical codes.
