HEPA Laminar Flow Workstation for Sterile Processing Departments

1. Product Concept

As a dedicated manufacturer of operating room equipment, we have applied our core expertise in airborne contamination control to the critical environment of the Central Sterile Supply Department. Haihao Clean Packaging Station is engineered specifically for the final assembly and wrapping of surgical instruments prior to sterilization. In this phase, cleaned instruments are most vulnerable to recontamination from ambient airborne particles, lint, and microbial fallout. By creating a localized ISO Class 5 clean air zone over the entire work surface, the Aseptix™ station ensures that every instrument set is packaged under conditions equivalent to those in an operating room, significantly reducing the risk of surgical site infections.

2. Surgical‑Grade Structural Design

The workstation is built to withstand the rigorous daily demands of hospital sterile processing while maintaining impeccable hygiene. The work surface is fabricated from heavy‑gauge 304 stainless steel with a minimum thickness of 1.5 mm, offering exceptional resistance to corrosion from cleaning agents, sterilants, and disinfectants. Its matte, anti‑reflective finish eliminates distracting glare, allowing staff to focus on detailed inspection and wrapping tasks without eye fatigue.

All joints are fully welded and ground smooth, creating a truly seamless surface with no crevices where biological debris could accumulate. Radiused corners of at least 10 mm facilitate thorough cleaning and eliminate bacterial harborage points. Every exposed edge is precision‑formed and deburred to protect both the user and delicate sterilization wraps from snagging or damage. The work surface is positioned at an ergonomic height of 850 mm, accommodating users of various statures and allowing comfortable seated or standing work postures.

3. HEPA Laminar Flow Technology

At the heart of the Haihao station lies a high‑performance air filtration system that delivers ISO Class 5 (Class 100) clean air directly to the critical work zone. A true HEPA H14 filter with certified efficiency of 99.995% at 0.3 microns removes airborne particles, bacteria, fungal spores, and other contaminants from the airstream. A washable pre‑filter captures larger particles and extends the service life of the main HEPA filter, reducing operating costs.

Purified air is directed downward in a uniform, unidirectional laminar flow pattern. This continuous air curtain sweeps away contaminants generated during packaging activities—such as lint from wraps, paper dust from indicators, and skin cells from personnel—and prevents ingress of unfiltered room air. The workstation maintains a slight positive pressure relative to the surrounding environment, ensuring that any air leakage is outward rather than inward. Airflow velocity is adjustable from 0.35 to 0.5 meters per second, allowing users to optimise conditions for different packaging tasks.

4. Integrated Illumination and Electrical Provisions

Proper lighting is essential for accurate instrument inspection and safe wrapping. The Haihao station features integrated LED light bars strategically positioned within the laminar flow hood to provide shadow‑free illumination across the entire work surface. The lights deliver 5500K daylight‑color illumination with a Color Rendering Index above 90, ensuring true‑to‑life colour rendering for visual inspection of instruments and chemical indicators. Flicker‑free operation reduces eye strain during extended use, and a dimming control allows users to adjust light intensity from 10% to 100% based on task requirements.

Multiple waterproof GFCI‑protected electrical receptacles are conveniently located for powering heat sealers, label printers, barcode scanners, and other packaging equipment. Optional integrated data ports support connectivity for computer workstations, enabling electronic tracking and documentation directly at the packaging station. Built‑in cable routing channels keep cords organised and prevent tangling.

5. Ergonomic Workflow and Storage Solutions

The Haihao station is designed to streamline the packaging workflow and reduce physical strain on staff. The generous work surface can be logically arranged into dedicated zones: an inspection area under the brightest illumination, a central assembly zone with ample clearance for organising instrument sets, a wrapping zone near the front edge for easy manipulation of wraps, and a sealing zone adjacent to electrical outlets.

Under‑counter stainless steel cabinets with soft‑close, self‑sealing doors provide secure storage for wrapping supplies, chemical indicators, and tracking labels. Adjustable shelving allows reconfiguration to accommodate supplies of varying sizes, while optional stainless steel drawers offer organised storage for small parts and instruments awaiting assembly. A convenient disposal chute allows staff to discard wrapping trimmings directly into a below‑counter receptacle, maintaining work surface cleanliness. An optional foot‑operated waste bin supports aseptic technique by enabling hands‑free waste disposal.

6. Model Configurations for Every Setting

The Haihao series offers multiple configurations to match the specific needs of different healthcare facilities.

The Haihao 600 Basic Model features a HEPA laminar flow system with fixed airflow, a 1500×700 mm stainless steel work surface, open‑base design with lower storage shelf, LED task lighting, and two GFCI outlets. It is ideal for small CSSD areas or satellite processing stations.

The Haihao 800 Standard Model adds adjustable airflow, under‑counter cabinets with self‑closing doors, dimmable LED lighting, four GFCI outlets, and a digital display with filter monitoring. This model suits most hospital sterile processing departments.

The Haihao1000 Advanced Model includes a 2000×800 mm work surface, full cabinetry with adjustable shelving and drawers, six GFCI outlets and data ports, a 7‑inch touchscreen interface, integrated UV disinfection cycle, and optional barcode scanner integration. It is designed for high‑volume central sterile departments.

Custom dimensions and configurations are available upon request, with a choice of 304 or 316L stainless steel and integration with existing instrument tracking systems.
