Kotohira KDC2-D01 Portable Dust Extractor (100V AC, Japan Import)

Overview

The Kotohira KDC2-D01 Portable Dust Extractor is an ultra-compact, high-static-pressure industrial vacuum system engineered for precision particulate capture in confined or mobile laboratory and light manufacturing environments. Designed and manufactured in Japan, this unit operates on standard Japanese single-phase AC 100 V (50/60 Hz) supply—making it suitable for integration into JIS-compliant cleanrooms, electronics assembly stations, analytical sample preparation areas, and R&D labs where space, weight, and electrical compatibility are critical constraints. Its core function relies on a brushless DC motor-driven centrifugal impeller optimized for high static pressure generation (up to 9.0 kPa), enabling effective suction through narrow-diameter hoses (standard Φ50 mm, with optional Φ38 mm adapters) even when filters become partially loaded. Unlike general-purpose shop vacuums, the KDC2-D01 is purpose-built for continuous-duty collection of fine non-hazardous dusts—including metal swarf, ceramic powders, solder flux residues, and abrasive polishing particles—with minimal acoustic emission (<65 dB(A) at 1 m) and thermal drift.

Key Features

• Ultra-compact footprint: 250 × 280 × 260 mm — among the smallest form-factor industrial dust extractors available globally for 100 V operation.
• High static pressure capability (9.0 kPa) ensures consistent suction performance across variable hose lengths and filter loading conditions.
• Lightweight construction (9 kg net weight) with integrated ergonomic carrying handle and rubberized anti-slip feet for stable tabletop or mobile cart mounting.
• Brushless DC motor provides extended service life, reduced maintenance intervals, and stable rotational speed under load fluctuations.
• Filter system includes a primary cyclonic pre-separator and a replaceable HEPA-grade (H13) main filter cartridge rated for ≥99.95% efficiency at 0.3 µm — compliant with ISO 14644-1 Class 5 cleanroom support requirements.
• Tool-free filter access and quick-release dust bin (3.2 L capacity) enable rapid maintenance without disassembly tools or downtime.

Sample Compatibility & Compliance

The KDC2-D01 is validated for non-explosive, non-oily, non-corrosive dry particulates with median particle sizes ranging from 0.5 µm to 500 µm. It is not rated for combustible dusts (per NFPA 484), wet slurry, or volatile organic solvents. The unit conforms to JIS C 61000-3-2 (harmonic current emissions), JIS C 61000-3-3 (voltage fluctuations), and meets CE marking requirements via third-party testing under EN 60335-1 and EN 60335-2-69 for household and similar electrical appliances. While not intrinsically safe, its design supports integration into ISO/IEC 17025-accredited laboratories where documented risk assessment for local exhaust ventilation (LEV) performance is required per ISO 10873 and EN 60204-1 safety standards.

Software & Data Management

The KDC2-D01 is a standalone analog-controlled device with no embedded microprocessor, network interface, or digital data logging capability. Operational status is indicated via a single LED power indicator; no firmware, calibration certificates, or audit trails are generated. As such, it satisfies GLP and GMP Annex 15 “non-automated equipment” validation pathways—requiring only periodic mechanical verification (e.g., static pressure check with calibrated manometer, airflow verification using anemometer per ISO 5801) and logbook-based maintenance records. Filter replacement intervals must be tracked manually based on differential pressure observation or time-in-service protocols aligned with internal SOPs.

Applications

• Precision machining stations: Capture aluminum, stainless steel, and titanium fines during CNC milling, EDM, and grinding operations.
• Electronics manufacturing: Removal of solder paste residue, flux fumes, and PCB drilling dust without static discharge risk.
• Materials science labs: Containment of graphite, tungsten carbide, and rare-earth oxide powders during weighing, sieving, and pelletizing.
• Pharmaceutical R&D: Local exhaust for low-risk excipient handling (e.g., lactose, microcrystalline cellulose) outside classified zones.
• Maintenance workshops: On-demand cleaning of optical components, metrology fixtures, and calibration standards prior to measurement.

FAQ

Is the KDC2-D01 compatible with 230 V or 120 V AC power systems?
No. The KDC2-D01 is exclusively designed for Japanese-standard single-phase 100 V AC (±10 %, 50/60 Hz). Operation on higher voltage supplies requires an externally certified step-down transformer rated for continuous duty at ≥300 VA.
Can this unit be used for wood or MDF dust collection?
It is not recommended. While capable of capturing coarse sawdust, the KDC2-D01 lacks explosion-proof construction and spark-resistant internals required for Class II hazardous locations per NEC Article 500. Use only with non-combustible particulates.
What is the expected service life of the HEPA filter under typical lab use?
Under controlled low-dust-load conditions (e.g., 1–2 hr/day usage in analytical prep), the H13 filter typically lasts 6–12 months. Filter life must be validated internally using differential pressure monitoring (replace when ΔP exceeds 2.5 kPa at nominal airflow).
Does Advantec provide factory calibration or traceable documentation?
As a Class A non-measuring auxiliary device per ISO/IEC 17025, the KDC2-D01 does not require calibration. Advantec supplies a Declaration of Conformity (DoC) and JIS-marked test report upon request, but no NIST-traceable calibration certificate is issued.
