A vertical laminar flow clean bench designed to provide ultra‑clean air above ISO 14644‑1 Class 5, suitable for pharmaceutical, clinical, hospital, life‑science, photoelectronic, and microelectronic environments. The HCB‑900V / HCB‑1300V series uses high‑efficiency filters, an ultraviolet sterilisation lamp with start‑up delay, and a vertical work face, with a 304 stainless‑steel work surface for easy cleaning, automatic pre‑clean, and an interlock between UV and fluorescent lamps, ensuring protection of both operator and sample during sensitive manipulations in cleanroom settings.
Airflow is vertical, with an average velocity of 0,2–0,4 m/s directed downward over the work surface, minimizing turbulence and allowing safe handling of microelectronics, cells, plates, sterile materials, and precision components. Both models run on 220/50 Hz (HCB‑900V) or 115/60 Hz and 220/50 Hz (HCB‑1300V), with a vertical filter housing and floor‑standing frame incorporating an integrated stand and universal castors that ease positioning and alignment on cleanbench worktables.
The 304 stainless‑steel work surface includes an automatic pre‑clean cycle that removes surface contaminants before sample handling begins. The UV sterilisation lamp implements a start‑up delay function: when the UV button is pressed, audible and visual alarms alert the operator to leave the area, and the system waits 10 seconds before full UV activation, reducing the risk of direct exposure. The UV lamp can be programmed from 0 to 24 hours, using one‑key preset and automatic on/off sequencing to standardise cycles and reduce waiting time between runs.
The microprocessor‑based control panel features durable push‑button touch switches and memory functions that save end‑of‑cycle settings, avoid repeated manual reconfiguration, and log operating parameters. A mandatory interlock between the fluorescent work lamp and UV lamp ensures the UV lamp can only run when the main lamp is off, and any turn‑on of the fluorescent lamp immediately cuts UV output, preventing unsafe operation. The recessed internal fluorescent illumination reduces glare and eye fatigue and provides uniform lighting over the work surface for long‑duration workflows.
