LC309-KB-WM Surface-Mount Stainless Steel Cleanroom Telephone, SIP / Analog / 4G
 
The LC309-KB-WM Surface-Mount Stainless Steel Cleanroom Telephone is a rugged wall-mounted communication device designed for cleanrooms, pharmaceutical production areas, laboratories, biotech facilities, food processing plants, hospitals, and controlled industrial environments.
Built with a durable stainless steel enclosure, this wall-mount cleanroom phone provides reliable voice communication in areas where hygiene, corrosion resistance, frequent cleaning, and long service life are important project requirements. The surface-mount design allows installation on cleanroom panels, solid walls, technical partitions, and controlled-area surfaces without requiring a large wall cut-out.
 
The LC309-KB-WM is available in SIP / VoIP, Analog, and 4G LTE versions, allowing the same standardized stainless steel cleanroom telephone platform to be used across different facility communication systems.
 
Designed for Cleanrooms and Controlled Environments
The LC309-KB-WM is suitable for controlled areas where standard commercial phones or adapted office devices may not provide enough durability, cleanability, or resistance to industrial use.
The stainless steel construction, sealed front interface, metal keypad, and vandal-resistant call button make the unit suitable for daily wipe-down procedures, humid environments, and frequent operation by personnel wearing gloves or PPE.
 
Typical environments include:
Pharmaceutical production and packaging areas
ISO-classified cleanrooms
Laboratories and biotech facilities
Hospitals and medical technical areas
Food processing facilities
Industrial wash-down environments
Controlled manufacturing areas
Clean corridors, gowning rooms, and secure production zones

Why Choose the LC309-KB-WM
The LC309-KB-WM is designed as a dedicated stainless steel cleanroom phone, not an adapted commercial device. This helps reduce long-term maintenance issues and provides a lower lifecycle cost in demanding facilities.
 
Key advantages include:
Fast surface-mount installation
No large recessed wall opening required
Strong stainless steel construction
Better resistance to corrosion, impact, and frequent cleaning
Suitable for cleanrooms and controlled industrial areas
Available in SIP, Analog, and 4G versions
One standardized platform for different communication technologies
Long service life under regular sanitation cycles
Professional industrial design for hygienic environments
 
Cleanroom Applicability
The LC309-KB-WM is suitable for controlled environments where cleanability, corrosion resistance, and durable communication hardware are required.
It can be used in ISO-classified cleanroom projects, pharmaceutical facilities, laboratories, food production areas, and other hygienic industrial spaces.
 
Note: Device suitability refers to enclosure material, surface construction, and installation design. Final cleanroom classification and validation remain the responsibility of the facility design, airflow, filtration, cleaning protocol, and qualification process.
