Air Quality

Excellent indoor air quality isn’t a privilege, it’s a right…

BAPI makes a complete line of air quality sensors for demand controlled ventilation including Volatile Organic Compount (VOC), Carbon Dioxide (CO2), Carbon Monoxide (CO) and Nitrous Oxide (NO2). The sensors feature a wide array of custom outputs so they are compatible with all lines of BAS controllers.

The room units are available with optional display, temperature measurement, humidity measurement, temperature setpoint adjustment and occupant override. The non-room units are designed for duct or rough service areas with a rugged BAPI-Box enclosure.

CO2 Sensors

BAPI’s CO2 sensor received an AHR Expo Innovation award because of their built-in Barometric pressure sensor that continuously compensates the output for accurate readings despite the weather or altitude. They come in two models– one that is optimized for continuously occupied areas and another that is optimized for periodically unoccupied areas.

VOC Sensors

BAPI’s VOC sensors respond to all air contaminants, rather than just CO2, for a more accurate indication of indoor air quality than a CO2 sensor alone.

BAPI-Stat Quantum VOC

  • Achieves true indoor air quality, not just CO2 dilution
  • Output is correlated to a CO2 value allowing you to ventilate using ASHRAE’s CO2 based VRP algorithm
  • BAPI-Stat Quantum enclosure with 0 to 5 or 0 to 10 VDC output

BAPI-Stat Quantum Prime VOC

  • VOC alone or temperature and humidity combination
  • Achieves true indoor air quality, not just CO2 dilution
  • Output is correlated to CO2 value allowing you to ventilate using ASHRAE’s CO2-based VRP

BAPI-Box Duct or Rough Service VOC

  • Corresponds to ASHRAE’s CO2-based DCV algorithm
  • Duct aspiration tube or rough service ventilated BAPI-Box
  • 0 to 5 VDC or 0 to 10 VDC output

Hazardous Gas Sensors

BAPI’s CO sensors are available for room, duct and rough service areas. The room units feature a 30ppm alarm trip level with relay and audible alarm. The duct and rough service units include four field-selectable CO ranges between 0 to 100 and 0 to 500ppm, large display and two independent alarm relays with field selectable CO concentration trip levels of 25, 35, 50, 100, and 200ppm. The NO2 units are available for duct and rough service areas and feature four field selectable ranges between 0 to 2.5 and 0 to 10ppm. They also include a large display and two independent alarm relays with field selectable NO2 concentration trip levels of 1, 2.5, 5, 7.5 or 10ppm.
