Product Details

The SureFlow Model 8636 Room Pressure Controller is the ideal digital controller for laboratories equipped with fume hoods and is designed to actually measure the differential room pressure that prevents chemical vapors from spreading outside the laboratory. The controller regulates supply airflow and total exhaust airflow to maintain laboratory ventilation and room differential pressure in accordance with standards such as NFPA 45-2000 and ANSI Z9.5-2003.

The Model 8636, as a stand-alone unit, regulates the supply and total exhaust dampers to ensure proper pressurization. It will also adjust the secondary heating and air intake to maintain minimum ventilation intake (air changes per hour) and cooling intake and to control the temperature of the laboratory space.

Model 8636 is easy to integrate with building management systems using alarm relays or digital communications. 8636 supports open MODBUS protocol.
