1. Understanding Clean Room Classifications and Standards
Clean rooms are classified by ISO 14644-1 standards, which define permissible particle counts per cubic meter. For example, ISO Class 5 (formerly Class 100) allows ≤3,520 particles ≥0.5µm/m³, while ISO Class 8 permits ≤3,520,000 particles[1][6]. These classifications dictate equipment specifications, from air filtration to material handling.
Key Standards for OEM Compliance:
- ISO 14644: Defines testing methods for particle counts, airflow, and pressure differentials[3][6].
- GMP Guidelines: Mandate smooth, non-porous surfaces and rigorous cleaning protocols[1][2].
- Federal Standard 209E: Historically used in the U.S., now largely replaced by ISO benchmarks[3].

2. Core Clean Room Equipment Requirements
2.1 Air Filtration and HVAC Systems
High-efficiency particulate air (HEPA) filters are non-negotiable, capturing 99.97% of particles ≥0.3µm[2][6]. Air handling units (AHUs) consume over 60% of facility power, emphasizing the need for energy-efficient designs with 80% recirculation rates[1].
Critical Components:
- Unidirectional Airflow: Prevents cross-contamination by directing air from ceiling vents to floor returns[2][6].
- Temperature/Humidity Control: Maintains stability for sensitive processes like semiconductor fabrication[4][6].
2.2 Surface and Material Compatibility
All surfaces must be smooth, non-shedding, and resistant to corrosion. Stainless steel and coated aluminum are preferred for workstations and fixtures[1][3].
Material Selection Guidelines:
- Non-Porous Walls: Epoxy-coated panels minimize microbial growth[1][5].
- Cleanroom-Grade Furniture: Static-dissipative tables and storage units prevent particle retention[3][5].
2.3 Contamination Control Tools
Essential Supplies:
- Apparel: Low-lint coveralls, hairnets, and shoe covers reduce human-borne particles[2][5].
- Cleaning Tools: HEPA vacuums, lint-free swabs, and tacky mats maintain surface cleanliness[5][6].

3. Advanced Monitoring and Validation Systems
3.1 Real-Time Particle Counters
These devices track airborne contaminants, ensuring compliance with ISO thresholds. For ISO Class 5 environments, continuous monitoring is mandatory[5][6].
3.2 Differential Pressure Gauges
Maintaining positive pressure prevents unfiltered air from entering critical zones. Alarms alert staff to deviations exceeding ±5%[5][6].
3.3 Temperature/Humidity Sensors
Wireless sensors provide data logs for audits, crucial for pharmaceuticals and electronics manufacturing[5][6].

4. OEM Partnership Considerations for Clean Room Design
4.1 Customization for Industry-Specific Needs
- Medical Devices: Require ISO Class 7 or higher, validated sterilization protocols, and traceability systems[4][6].
- Semiconductors: Need vibration-resistant equipment and ESD-safe tools for nanoscale production[4][6].
4.2 Scalability and Maintenance
Modular clean rooms allow OEMs to expand capacity without compromising existing systems. PEKO Precision's ISO Class 6 facility, for instance, uses pre-cleaning staging areas to streamline workflows[4].

5. FAQs on Clean Room Equipment Requirements
Q1: What's the difference between ISO Class 5 and ISO Class 8 clean rooms?
A1: ISO Class 5 allows ≤3,520 particles ≥0.5µm/m³, while ISO Class 8 permits 3,520,000, impacting filtration and airflow designs[1][6].
Q2: How often should HEPA filters be replaced?
A2: Typically every 2–3 years, but continuous monitoring data dictates precise schedules[2][6].
Q3: Can existing factories be retrofitted into clean rooms?
A3: Yes, but structural upgrades like sealed walls and dedicated HVAC are essential[1][3].
Q4: What materials are prohibited in clean rooms?
A4: Porous materials (e.g., wood), shedding fabrics, and non-static-safe plastics[3][5].
Q5: How do pressure differentials prevent contamination?
A5: Higher pressure in cleaner zones pushes air outward, blocking unfiltered inflows[2][6].
