Cleanroom Drainage, Hygiene and Safety Equipment
Aspirating Smoke Detection System
An active air-sampling detector that draws room air through a pipe network for sensitive, centralized smoke analysis.
- Active Air Sampling
- Multi-Level Early Warning
- Supervised Pipe Network
- Serviceable Central Detector
Product Introduction
The aspirating smoke detection system uses a monitored fan to draw air from distributed sampling holes through small-bore pipes into a filtered optical sensing chamber. Multiple alarm thresholds can distinguish developing conditions from established fire signatures, while airflow supervision reports blocked or broken sampling lines. Locating the detector cabinet in a serviceable position allows filter and chamber maintenance without opening every cleanroom ceiling point.
Key Features
Configurable thresholds support staged investigation and alarm response.
Airflow monitoring detects pipe blockage, leakage or fan faults.
Replaceable filters protect the optical chamber from background contamination.
Customer Product Concerns
Dilution and directional airflow can delay passive detection, while cleanroom access makes frequent ceiling-device maintenance undesirable.
High air-change rates move smoke away from passive ceiling detectors.A distributed sampling network actively transports room air to the sensing chamber.
Very low alarm thresholds can react to harmless background particles.Filtration, reference settings and staged thresholds separate background from developing smoke.
A blocked sampling hole silently reduces coverage.Continuous airflow supervision reports deviation from the commissioned pipe baseline.
Servicing many room detectors disrupts controlled operations.The fan, filter and chamber are centralized in one accessible cabinet.
Typical Applications
Semiconductor cleanroomsPharmaceutical production suitesData and control roomsHigh-bay controlled spaces
