Laboratory room air flow regulators

LFR regulates the inputs and outputs of air considering the laboratory air volume extractions needs. LFR is made of a control card, a motor, and a mechanical part. Depending on its use and needs, the mechanical part can be available in both galvanized steel and PVC.

• Max power consumption: 5VA
• Analog inputs: 0...10Vdc ou 4...20mA
• Analog outputs 0..10Vdc
• Configurable dry contact output relay
• Integrated sensor: Pressure (0-500Pa)
• External sensor (optionel): Temperature
• Communication: Bus CAN High speed - protocole COMnet
• Temperature resistance: from 10°C to 40°C
• Ducting diameter: 200 / 250 / etc. (see doc)

VFR is an air extraction control system. It allows to regulate the room extraction rates (For the Recovery version) or in ducting (for the standard version). LFR is made of a control card, a motor, and a mechanical part. Depending on its use and needs, the mechanical part can be available in both galvanized steel and PVC.

• Power supply: 24 Vac/dc
• Max power consumption : 5VA
• Analog inputs : 3 inputs 0..10Vdc
• Outputs frequency inverter/registrer set up : 0-2..10Vdc or 0..10Vdc
• Integrated sensor : Pressure (0-500Pa)
• Communication : Bus CAN High speed - protocole COMnet
• Temperature resistance : from 10°C to 40°C
• Ducting diameter : 200 / 250 / etc. (see doc)

 HFRallows to control and maintain the extraction flow of a hood according to the demand. HFR is made of a control card, a motor, and a mechanical part. Depending on its use and needs, the mechanical part can be available in both galvanized steel and PVC.
