• 8 Inch - 130-235 CFM - Modulo Constant Airflow Regulator (CAR) by American ALDES

    MR Modulo Adjustable Constant Airflow Regulators balances airflows in heating, ventilation or air conditioning ductwork. They fit easily into round ductwork to maintain constant and reliable airflow within a wide range of differential pressure (0.2-1.0 in. w.g./50 - 250 Pa). The MR Modulo's flexible membrane inflates and deflates according to the difference in pressure between the upstream and downstream flow, thus self-adjusting the airflow. This principle of operation guarantees constant airflow regardless of pressure variations in the ductwork. Available in 4"(10-50 CFM), 5"(10-50 CFM), 5"(60-115 CFM), 6"(60-140 CFM), 8"(130-235 CFM) and 10"(175-385 CFM).

  • ALDES ZRT2, 4" 24V Hi-Low Flow Zone Register Terminal with Constant Airflow Regulator - ZRT-2-4-24R

    The patented Zone Register Terminal (ZRT) ZRT-2-4-24 is designed to introduce flexibility and dynamic control to central fans or air exchangers in single-family and low-rise multi-family homes. The ZRT is a combination grille/register box and control damper and Constant Airflow Regulators (CAR-II) replacing the traditional ventilation fan in bathrooms, laundry rooms and other spaces. In its "OFF" state, the ZRT-2 precisely ventilates the space at a rate of 10, 20 or 30 CFM to provide continuous ventilation in the home. When turned "ON", the ZRT-2 provides a high rate of ventilation in the home through a central fan or air exchanger. This delivers extremely energy efficient ventilation while eliminating extra roof or wall caps on the home. The ZRT enables a single central fan or air exchanger to provide extremely quiet low & high speed zoned ventilation to specific spaces in the home as needed. The ZRT-2-4-24 uses 4" duct connected to a central fan or air exchanger. It is designed to provide zone-controlled spot ventilation and continuous whole house ventilation utilizing a 24V damper to turn the ventilation on and off from spaces in use. This saves energy, reduces noise, improves comfort and improves IAQ (per ASHRAE 62.2 standards). The ZRT-2 can be controlled with ALDES controls...

  • HEAVY DUTY HIGH FLOW 3/4" IN-LINE COMPRESSED AIR PRESSURE REGULATOR, 7 TO 215 PSI ADJUSTABLE, BRACKET, GAUGE

    ADJUSTABLE FROM 7 PSI TO 215 PSI, 160 SCFM FLOW RATE A pressure regulator's primary function is to match the flow of gas through the regulator to the demand for gas placed upon it, whilst maintaining a constant output pressure. If the load flow decreases, then the regulator flow must decrease also. If the load flow increases, then the regulator flow must increase in order to keep the controlled pressure from decreasing due to a shortage of gas in the pressure system. High pressure gas from the supply enters into the regulator through the inlet valve. The gas then enters the body of the regulator, which is controlled by the needle valve. The pressure rises, which pushes the diaphragm, closing the inlet valve to which it is attached, and preventing any more gas from entering the regulator. The outlet side is fitted with a pressure gauge. As gas is drawn from the outlet side, the pressure inside the regulator body falls. The diaphragm is pushed back by the spring and the valve opens, letting more gas in from the supply until equilibrium is reached between the outlet pressure and the spring. The outlet pressure therefore depends on the spring force, which can be adjusted by means of an adjustment knob.

  • Constant Airflow Regulator 4" (30-60 CFM)

    The Constant Airflow Regulators control of the airflow is essential to optimize energy consumption while providing good air quality. Introducing Constant Airflow Regulator by eFlow USA. Our Constant Airflow Regulators, also known as Automatic Balancing Dampers are UL Classified devices that automatically adjust to environmental changes in stack pressure and accurately regulate airflow. Constant airflow regulators are self-regulating and adjustable flow-regulators for commercial and residential buildings. The requested airflow is fixed by a screw driver. It is automatically calibrated to varying pressures without using electricity. Constant airflow regulators save energy and money by precisely controlling airflow into or out of space, regardless of static pressure, and all along providing good air quality. Other sizes available 3" 4" 5" 6" 8" 10" For technical support call 1-833-FLOW-USA
