Introduction to Airflow Management System:

The Airflow Management System is an interconnected control device that regulates the pressure difference between adjacent spaces by controlling the ratio of exhaust and supply air.

SPR-JK200YAirflow Management Main Unit

Designed for negative pressure isolation ward areas, it monitors and controls air pressure difference, air volume, air velocity, valve status, fan operation, ward disinfection, audible and visual alarms, and fault display. Through real-time monitoring, it also performs interconnected control of equipment operational status.

Working PrincipleThe Airflow Management Main Unit communicates with airflow controllers via a two-wire bus, collecting operational status from fans, manual controllers, micro differential pressure sensors, and electric actuators (exhaust/supply air valves). It provides audible and visual indications, records, and prints alarm or fault information. The main unit offers alarm or fault location details to nursing stations or duty rooms, enabling staff to monitor system status and promptly address alarms or faults.

Installation LocationThe Airflow Management Main Unit is wall-mounted in nursing stations or duty rooms. [Note: One unit per nursing station or duty room is sufficient.]

SPR-ZK20EAirflow Controller

Used in negative pressure ward airflow management systems to control the start/stop and speed of supply and exhaust fans.

DefinitionThe Airflow Controller, also known as a Fan Controller, is used in negative pressure ward airflow management systems to regulate the start/stop and speed of exhaust/supply fans.

Application AreasNegative pressure wards, cleanrooms, staircase pressurization systems, garage exhaust systems, etc.

Working PrincipleThe Airflow Controller communicates with the interconnected controller. Based on the operating mode set by the manual controller, it sequentially starts/stops exhaust/supply fans and adjusts the frequency converter according to the opening ratio of exhaust/supply air valves to control fan speed.

Installation LocationThe Airflow Controller is installed in the fan distribution box, with a 1:1 ratio to fans. Each fan requires one airflow controller.

SPR-YP21E; SPR-YC21Micro Differential Pressure Manual Controller

Used in negative pressure ward airflow management systems to monitor and manually control the air pressure difference within the ward.

DefinitionThe Micro Differential Pressure Manual Controller is one of the main devices in negative pressure ward airflow management systems, used to monitor and manually control the air pressure difference inside and outside the ward.

Application AreasNegative pressure wards, cleanrooms, etc.

Working PrincipleThe Micro Differential Pressure Manual Controller, installed at the ward entrance, monitors and controls the relative pressure difference inside and outside the ward in real time. It features preset operating modes for automatic or manual control of air volume regulating valves (supply and exhaust air valves). In cleaning mode, it facilitates disinfection of the ward after patient discharge.

Installation LocationInstalled at the ward entrance, medical corridor, or buffer room, within visual range at a height of approximately 1.5m to 1.6m.
