LC309-KB-OW Flush-Mount Stainless Steel Cleanroom Telephone (SIP / Analog / 4G)
Stainless Steel Flush Communication for Cleanrooms & Controlled Environments | SIP · Analog · 4G | IP55–IP65 · IK10 · CE · FCC · RoHS · ISO 9001 | 2-Year Warranty
The LC309-KB-OW Flush-Mount Stainless Steel Cleanroom Telephone (SIP/4G/Analog) is a robust industrial communication terminal designed for cleanrooms, pharmaceutical production areas, laboratories, and hygienic industrial environments where durability, corrosion resistance, and vandal protection are critical project requirements.
Manufactured from stainless steel with a wire-drawing finish, this model provides enhanced resistance to impact, humidity, chemical cleaning agents, and mechanical abuse while maintaining a clean flush-mounted appearance suitable for controlled environments.
This device is engineered for long-term reliability, daily sanitation cycles, and straightforward integration into cleanroom wall panels and industrial partitions.
ISO Cleanroom Applicability
Suitable for ISO Class 5 to ISO Class 9 environments
Designed for wipe-down cleaning protocols
Flush-mount design supports validated cleaning procedures
Note: Device suitability refers to surface material and flush construction. Final room classification remains the responsibility of facility airflow and validation design.
The LC309-KB-OW ensures:
Safe, hygienic, and reliable communication without compromising cleanroom integrity.
