eFlow-CAR is a factory set Constant Airflow Regulator designed to save significant amounts of energy and money by precisely controlling airflow into or out of space, regardless of static pressure, and all along providing high Indoor Air Quality (IAQ). eFlow CAR is composed of fire resistant ABS plastic. It contains a self regulating aero-wing and spring piston design to maintain a factory preset air flow. These CARs are designed to operate in pressure range Low Pressure (.08”-4″w.c.), Standard Pressure (0.2″-1″ w.c) and High Pressure (0.6”-2.4″ w.c). They automatically adjust for variable duct pressures caused by building pressure, thermal stack effect, dust build up and other variable factors. This Constant Airflow Regulator creates a cost effective answer to balancing air systems for HVAC and ventilation in high rise buildings, without the requirement for on-site balancing, electrical/pneumatic controls or sensors. eFlow-CAR may contribute to meeting USGBC LEED Building and Passive House Certification. Flow CAR requires no maintenance under normal conditions.
Standard Construction eFlow-CAR: Classified UL R38307 / UL-2043 for heat release rate and smoke optical density.
