The Horizontal Laminar Flow Hood is a high-performance clean air workstation designed for sterile and particle-sensitive laboratory operations. It provides an ISO Class 5 (Class 100) clean environment through a horizontal laminar airflow system, effectively preventing contamination of samples and workpieces.

Equipped with a high-efficiency HEPA filter (99.99% filtration efficiency at ≥0.3 μm), ultra-clean air flows uniformly across the work surface, continuously removing airborne particles and microorganisms. With user-friendly controls, low-noise operation, and a corrosion-resistant stainless steel work surface, this clean bench ensures reliable performance, operator comfort, and long-term durability.

It is widely used in biomedicine, cell culture, pharmaceutical research, precision instrument assembly, electronics manufacturing, and inspection laboratories.

Q1: How long does the HEPA filter last, and how is it replaced?
A: The HEPA filter typically lasts 1–3 years, depending on usage frequency and environmental cleanliness. Replacement should be performed after powering off the unit. Professional assistance is recommended to ensure proper installation and performance.

Q2: Is this clean bench suitable for cell culture or biosafety experiments?
A: It is ideal for cell culture and aseptic operations. However, for handling hazardous microorganisms, a biosafety cabinet is recommended to ensure personnel and environmental protection.

Q3: Can the airflow speed and noise level be adjusted?
A: Yes. The airflow speed is adjustable within 0.3–0.6 m/s, and the unit operates at a low noise level of ≤65 dB for comfortable use.

Q4: How should the clean bench be cleaned and maintained?
A: Regularly wipe the work surface with 75% alcohol or sterile wipes, avoid blocking air inlets, and inspect the HEPA filter every 6–12 months to maintain optimal performance.
