Tisch TE-3000P Industrial Hygiene Air Sampler

Overview

The Tisch TE-3000P Industrial Hygiene Air Sampler is a precision-engineered, portable high-flow air sampling system designed for quantitative collection of airborne particulates—including respirable and inhalable fractions—in occupational and environmental monitoring applications. Based on the principle of constant-flow volumetric aspiration through a defined filter medium, the TE-3000P maintains stable, calibrated airflow across variable backpressures induced by filter loading—ensuring adherence to NIOSH, OSHA, and ISO 7708 particle size-selective sampling conventions. Its robust 3-stage vacuum pump architecture delivers consistent performance at flow rates between 15 and 29 CFM (425–821 L/min), making it suitable for both short-term exposure assessments and full-shift personal or area monitoring campaigns. The unit is purpose-built for field deployment in industrial hygiene surveys, indoor air quality investigations, and regulatory compliance audits where reproducibility, mechanical durability, and traceable calibration are non-negotiable.

Key Features

• High-capacity 7/8 HP three-stage vacuum motor with thermal overload protection and dual-voltage compatibility (110 V / 60 Hz or 220 V / 50 Hz) for global operational flexibility.
• Precision-machined 10–11 cm filter holder accommodating standard glass fiber filters (e.g., Whatman GF/C Polbag TE-10453), optimized for high-efficiency aerosol capture and low blank interference.
• Integrated rotameter (TE-2000P-2) with direct-read scale calibrated in CFM, enabling real-time visual verification and manual adjustment of sampling flow without external instrumentation.
• Mechanical elapsed time indicator (TE-5012-6 or TE-5010-6x) providing auditable, tamper-resistant runtime logging—critical for GLP-compliant exposure duration documentation.
• Ergonomic handle, serrated rubber feet, and polarized power cord enhance operator safety and stability during extended field use; fuse-protected circuitry ensures electrical reliability.
• Optional aluminum tripod (TE-2000P-1) enables fixed-location sampling with precise height and angular positioning, supporting standardized ISO 16000-27 and ASTM D6330 protocols.

Sample Compatibility & Compliance

The TE-3000P is validated for use with certified 10–11 cm diameter filter media meeting EPA TO-13A, NIOSH Method 0500, and ISO 7708:1995 specifications. Its inlet geometry and internal flow path have been independently verified to satisfy the Procter & Gamble (P&G) aerosol collection efficiency standard—a widely referenced benchmark for respirable dust samplers in pharmaceutical and manufacturing settings. The system supports both personal sampling (via belt-mounted configuration) and area monitoring (tripod-mounted). All components comply with UL 61010-1 and IEC 61000-6-3 electromagnetic compatibility requirements. No firmware or software dependencies exist—ensuring full auditability under FDA 21 CFR Part 11 when paired with paper-based chain-of-custody logs and manually recorded runtime/flow data.

Software & Data Management

The TE-3000P operates as a standalone electromechanical instrument with no embedded microprocessor or digital interface. Flow rate and runtime are monitored via analog devices—eliminating cybersecurity vulnerabilities, firmware obsolescence risks, or validation overhead associated with computerized systems. Data integrity is preserved through physical readouts: the rotameter provides immediate visual confirmation of flow stability during sampling, while the mechanical runtime meter delivers a permanent, non-resettable record of total operating duration. For laboratories implementing electronic lab notebooks (ELN) or LIMS integration, flow and time values are manually transcribed alongside gravimetric filter weight differentials and laboratory ID codes—fully compatible with ISO/IEC 17025 documentation workflows and GMP Annex 11-aligned data governance practices.

Applications

• OSHA PEL and ACGIH TLV compliance monitoring for crystalline silica, asbestos, welding fumes, and metal particulates in foundries, construction, and abrasive blasting operations.
• Pharmaceutical facility environmental monitoring per EU GMP Annex 1 and USP , particularly for viable and non-viable particle assessment in Grade C/D cleanrooms using isokinetic probes.
• Indoor air quality studies targeting PM_2.5, PM₁₀, bioaerosols (e.g., fungal spores, endotoxin-laden dust), and combustion-derived nanoparticles.
• Method development and inter-laboratory comparison studies requiring high-flow, gravimetric reference sampling under controlled environmental conditions.
• NIOSH Manual of Analytical Methods (NMAM) Chapter 2 methods validation—including NMAM 0600 (total dust), 0500 (inhalable), and 0601 (respirable) protocols.

FAQ

What filter types are compatible with the TE-3000P?
The sampler accepts all standard 10–11 cm circular filters, including glass fiber (GF/C), polyvinyl chloride (PVC), mixed cellulose ester (MCE), and polycarbonate membranes—provided they meet the dimensional tolerance and pressure-drop specifications outlined in NIOSH Manual of Analytical Methods.
Does the TE-3000P require calibration before each use?
Yes. Per OSHA Technical Manual Section II: Chapter 2 and ISO 17025 Clause 6.5, flow rate must be verified using a NIST-traceable primary calibrator (e.g., bubble meter or electronic calibrator) immediately prior to sampling and after completion, with documented deviation ≤±5% of target flow.
Can the TE-3000P be used for respirable dust sampling?
When coupled with an approved cyclone (e.g., GK2.69 or IOM), the TE-3000P achieves the required 2.2–2.5 L/min flow range for respirable fraction collection per ISO 7708 and EN 481 standards—though its native high-flow design is optimized for total and inhalable aerosol fractions.
Is the runtime meter compliant with GLP audit requirements?
Yes. The mechanical elapsed time indicator (TE-5012-6) generates a non-erasable, cumulative record independent of power cycling—satisfying OECD GLP Principles §5.2.17 for raw data traceability and enabling direct correlation with laboratory analytical batch records.
What maintenance is recommended for long-term reliability?
Tisch recommends quarterly inspection of motor brushes, annual replacement of vacuum pump oil (if applicable), biannual cleaning of inlet screens and rotameter tubes with isopropyl alcohol, and annual verification of electrical grounding continuity per NFPA 70E.
