TSI SUREFLOW™ Room Pressure Controls are designed to actually measure the room pressure differential used to prevent chemical vapors from escaping outside the lab. Monitor versions are used in constant volume laboratories to warn building occupants of operating deficiencies. Controller versions go a step further by modulating supply and exhaust air volumes to correct problems as they occur, while maintaining comfort and ventilation within the lab space.

• Direct measurement continuously monitors actual room pressure differential
• Room pressure monitoring is independent of fume hoods, providing system redundancy
• Provides visual, audible and alarm contacts
• Measures supply flow, calculates air changes per hour
• Integral keypad for configuration and calibration
• Passwords limit unauthorized access
• Integrates to building automation system using RS-485 communications with MODBUS or Johnson Controls N2 protocols
• Optional LonWorks communications available on selected controllers

• Energy efficiency
• Laboratory safety
• Laboratory comfort

• 120:24-VAC transformer
• 25-ft transformer cable
