Available in standard sizes (600×600mm, 1200×600mm) and filtration grades (HEPA H14, ULPA U15/U16), it maintains ISO Class 3-8 cleanliness levels. The low-noise design (<52dB) and slim profile (150mm height) make it ideal for semiconductor, pharmaceutical, and electronics manufacturing cleanrooms.
In Class 1-100 semiconductor cleanrooms, the PuriFan EFU’s ULPA U16 filtration removes 99.9995% of 0.12μm particles, preventing wafer contamination during lithography and etching processes. The EC motor’s variable speed control adapts to dynamic air volume needs, cutting energy costs for 24/7 operations.
For GMP-compliant API (Active Pharmaceutical Ingredient) cleanrooms, the HEPA H14-equipped EFU ensures airborne particle counts meet EU GMP Annex 1 standards. Its quick-release filter frame allows fast replacement without disrupting cleanroom integrity, minimizing production downtime.
In Class 7 medical device cleanrooms, the PuriFan EFU’s uniform airflow distribution maintains consistent cleanliness across assembly stations. The corrosion-resistant aluminum housing withstands frequent disinfectant cleaning, supporting hygiene protocols for implantable device production.
Dimensional diagram
EC motor technology: 30-100% speed adjustment, 0.5kW power rating, and 50,000-hour service life.
Filtration options: HEPA H14 (99.995% @0.3μm) or ULPA U16 (99.9999% @0.12μm) with gel seal.
Low noise operation (<52dB) and vibration-free design protect sensitive equipment.
Smart monitoring: optional differential pressure gauge and wireless status alerts.
Easy installation: drop-in ceiling mount compatible with standard T-grid systems.
Our services include cleanroom layout optimization (EFU quantity/cplacement calculation), on-site installation, and filter integrity testing (DOP method). We provide 1-year warranty on EC motors and offer filter replacement subscriptions. Customization options: non-standard sizes, stainless steel housing, and integrated LED lighting. Documentation includes filter test reports, energy efficiency certificates, and installation manuals.
A1: HEPA filters last 12-18 months in standard cleanrooms; ULPA filters last 18-24 months. Replacement is recommended when differential pressure reaches 250Pa (initial: 100Pa). We offer pressure monitoring kits for proactive maintenance.
A2: Yes. We modify the motor and airflow direction for negative-pressure applications (e.g., biosafety labs). The unit maintains stable performance in pressure ranges from -50Pa to +100Pa.
A3: The EC motor uses 40% less energy than AC motors. Variable speed control reduces power consumption during low-activity periods, and the high-efficiency airflow design minimizes HVAC system load—saving $300-500 per unit annually.
