​Overview​​
The VENTEST-300 is a compact yet robust system for testing the filtration efficiency and airflow resistance of HVAC filters, cleanroom media, and industrial exhaust systems. Designed for quality control teams and environmental engineers, it delivers repeatable measurements of PM2.5/PM10 capture rates and pressure drop across a wide range of flow conditions (10–500 m³/h).

​​Core Features​​

1. ​​Aerosol Generation​​: Dry/wet aerosol systems produce particles from 0.3–10 µm to simulate real-world particulate challenges.
2. ​​Dual-Sensor Array​​: Combines laser photometry (±0.5% accuracy) and piezoelectric sensors to measure penetration rates and pressure drop.
3. ​​Modular Design​​: Swappable filter holders accommodate flat panels, pleated filters, and bag filters (10–100 cm²).
4. ​​Data Analytics​​: Real-time software generates ISO 16890-compliant reports with MERV ratings and energy consumption metrics.

​​Applications​​

• ​​HVAC Systems​​: Certifies residential and commercial air filters for energy efficiency (MERV 1–20).
• ​​Cleanroom Certification​​: Validates HEPA filters in pharmaceutical manufacturing (ISO 5–Class 1).
• ​​Industrial Safety​​: Tests explosion-proof filters in oil refineries and chemical plants.

​​Compliance​​
ASHRAE 52.2, EN 779, GB/T 14295.

​​Optional Add-Ons​​

• High-volume pumps (up to 1,000 m³/h).
• Environmental chambers (-20–60°C).
• Cloud-based data management platforms.
