Product Introduction:
The Class A liquid-bath laminar flow hood is an air purification device specifically designed for localized, high-cleanliness environments, making it ideal for process steps with stringent cleanliness requirements. By employing high-efficiency filtration and directional laminar flow technology, it provides a stable Class A clean environment in the operational area, effectively controlling particulate and microbial contamination.
Core design:
1. Structural Composition
Featuring a modular design, it integrates a fan, a multi-stage air filtration system, and an intelligent control system. It supports both ceiling-mounted and floor-standing installations, making it suitable for various space requirements. The unit’s housing is made of high-quality stainless steel with a seamless surface design, facilitating easy cleaning and disinfection.
2. Cleanliness Assurance
Through a dual-stage filtration system—comprising primary and high-efficiency filters—continuous, unidirectional, vertical laminar airflow is delivered, ensuring that the cleanliness of the work area meets Class A standards (dynamic ≥ ISO Class 5).
3. Flexible Expansion
The unit can operate independently or be connected in multiple units to form a continuous clean zone, making it suitable for assembly-line operations or large-scale cleanroom coverage needs.
Product Advantages
- Stable and Clean: Directed laminar flow design maintains high air cleanliness on the operating surface.
- Flexible adaptation: Optional installation methods, supporting personalized scenario configurations.
- Easy maintenance: Modular structural design ensures convenient filter replacement.
- Durable and reliable: Made of stainless steel, it’s corrosion-resistant and maintains its shape even after long-term use.
Applicable scenarios:
Process steps such as sterile filling in biopharmaceutical manufacturing, assembly of precision electronic components, and dispensing of highly sensitive reagents in laboratories—all of which require locally ultra-clean environments—are particularly well-suited for cleanroom protection of critical workstations.Instructions 1.
