Horizontal Laminar Airflow Trolley – Optimal Solution for Clean Environments
Introduction
In production and research environments where strict cleanliness control is required, equipment that protects products from dust, bacteria, and other contaminants is essential. Among these, the horizontal laminar airflow trolley is an ideal solution for maintaining a sterile working area even during internal transportation.
I. What is a Horizontal Laminar Airflow Trolley?
A Horizontal Laminar Airflow Trolley is a mobile device designed to create a localized clean environment by using horizontal laminar airflow. It protects sensitive products such as electronic components, pharmaceuticals, medical instruments, or laboratory samples from airborne contamination caused by dust particles, microorganisms, and external pollutants.
II. Operating Principle
The trolley operates based on the laminar flow principle, ensuring a steady and continuous stream of clean air flowing from back to front in a horizontal direction:
- Air is drawn from the surrounding environment by an intake fan.
- A pre-filter removes coarse dust and large particles.
- A HEPA filter captures up to 99.97% of particles ≥ 0.3 microns in size.
- The clean air is then blown across the working area, forming an “air curtain” that isolates it from external contamination, keeping the contents protected in a sterile zone.
III. Standard Components
A horizontal laminar airflow trolley typically includes the following components:
- Outer frame: Made of 304 stainless steel or powder-coated steel, durable and easy to clean.
- Air filtration system:Airflow fan: AC or EC type, energy-efficient and quiet.
- Pre-filter for large particle removal
- HEPA filter for cleanroom-grade air purification
- Working area: Fully or semi-enclosed to maintain airflow integrity.
- Power source: Operates on mains power or integrated backup battery (UPS) for 2–4 hours of independent use.
- Caster wheels: 360° rotating wheels with locks for easy movement and stability.
- DOP test port (optional): Allows regular testing of HEPA filter integrity.
IV. Key Features
- Stable laminar airflow for effective and non-turbulent protection of products.
- High mobility, suitable for dynamic or changing workspace layouts.
- Complies with ISO Class 5 cleanroom standards.
- Energy-efficient operation through optimized fan and power system.
- Durable materials, corrosion-resistant, and easy to sanitize after use.
- Flexible design with customizable sizes and configurations to meet specific requirements.
V. Practical Applications
The horizontal laminar airflow trolley is widely used in various fields requiring high levels of contamination control:
- Pharmaceutical industry: For transporting raw materials and finished drugs within clean manufacturing processes.
- Electronic manufacturing: Protecting microchips and circuit boards from dust and static particles.
- Medical and hospital environments: Used in operating rooms or laboratories for moving instruments or biological samples.
- Food industry: Transporting sensitive items like dairy products, breast milk, and fermentation ingredients.
- Scientific research laboratories: Maintaining sample integrity during handling and internal transfers.
